69 Stories To Learn About Productivity Tools

It’s Tuesday at 8:32 a.m. Sarah, a facilities manager, is darting off to work. She offers a quick goodbye to her twelve-year-old daughter, who’s texting a friend and listening to music on her Bluetooth headphones. Sarah gets into her EV, which automatically connects to her phone, and begins playing a song from her 80’s playlist. Upon Sarah’s entry, the car adjusts the seats and steering column height according to her preferences. On the drive to work, she uses a virtual assistant to call her husband to remind him of a dinner commitment that night. Finally, Sarah gets to work and wants to run an energy consumption report for two of her buildings. However, her submeter app and her energy dashboard don’t connect natively. Frustrated, Sarah calls her integrator for help. They give her an estimate of a week. Most of us understand Sarah’s frustration. It’s almost absurd how much connectivity, personalization, and power we possess in our ordinary lives that isn’t translated to working with buildings. Like Sarah, we often think: “ is ” Why the hell is this so hard to do when using our personal devices so easy! There’s a reason why Sarah and many of us in the automated buildings industry have this experience. All our everyday gadgets and technology today use cloud-native architecture. Imagine if your building gave you as much power to connect, to manage, and to create as your smartphone did. In general, the automated buildings industry has been slow to adopt cloud-native technology, and our buildings and stakeholders like Sarah are paying the costs. But there’s a way for the industry to embrace the power of cloud-native and transform our properties into powerhouses of integration and automation. It’s the Interoperable Building Box or IBB from the Coalition for Smarter Buildings ( ). C4SB Why Do We Need an IBB? Today, the smart buildings industry is facing an onslaught of challenges and disruptions from multiple sides. Building information systems are getting increasingly complex—more sensors, more points, more systems, AI, and digital twins. We have a flood of information and streams of data, yet no single nozzle that will do the work of putting out the fire. We also have incredible applications that do wonderful things, but getting them to work and communicate with each other seems to always be a Herculean task. The amount of effort and time is a major pain point for folks like Sarah, who expect things to work as easily as everything else in their lives. For most, the benefits of integration outweigh the level of effort. This is the main reason for the slow adoption rate. only just The industry’s slow shift to cloud-native is revealing a serious skills gap. Cloud-native has been the standard architecture for IT departments for years now, and the onboarding of OT into the cloud-native space is beginning to blur the lines between the two. IT and OT are converging, and knowledge of both is becoming a prerequisite. Today, it’s difficult to find enough workers with the skills and knowledge level to tackle both. All these challenges hobble the goal of delivering smart technology at scale. Overcoming these obstacles requires technology that facilitates app integration while also improving the experience of industry stakeholders like Sarah. Instead of retooling our entire workforce, we can retool the way we interface with building systems. What is an Interoperable Building Box or IBB? Let’s start with a technical definition: The IBB (Interoperable Building Box) is orchestration software running on a physical or virtual machine that exists on-prem; the IBB acts as a standardized interface to connect a building’s local network to the . The IBB runs containerized cloud-native applications and services based on the Open Container Initiative ( ) standard. The IBB makes deploying and managing containerized software easier and more secure and provides an automated way for systems to discover and connect with systems having matching capabilities both within the IBB or in the Cloud in a plug-and-play manner. Internet Cloud OCI The purpose of the IBB is to make a building cloud native. That is, all its technologies and apps are built to work within (i.e., “native to”) a cloud environment. It must also support standard cloud functionalities like containerization, dockers, and orchestration (Kubernetes). By functioning like a standard cloud provider, the IBB allows the building to reap the advantages of localized control, namely better resiliency, security, and faster access. inherently Imagine “A Smartphone for Your Building” In a way, you can think of the IBB as a “smartphone for your building.” Consider all the ways your phone expands your capacity to do things. You can talk to anyone, anywhere, at any time. You can download, install, and run almost an unlimited number of apps. You can connect to the internet, access cloud storage, store local data, share files with your computer, and connect to wireless devices. In the same way, the IBB expands your building’s potential by providing it greater power to communicate and connect. Overall, your property becomes exponentially more efficient and productive. And because the IBB is located on-prem (i.e., in your building’s “pocket”), it can reliably deliver secure local storage of sensitive data and low latency times. For example, data from equipment sensors need not make the long round-trip to a cloud platform and back again. Data storage and computation are already . Such local processing makes storage of sensitive information more secure, while low latency times help protect critical systems and sensitive equipment, while the cloud connection automatically creates a copy of such data for backup and analysis in the cloud. This is analogous to taking a picture on your smartphone; you can see the image immediately, and it is also stored in your cloud photo album. in the building Parts of the IBB At the heart of IBB is containerization—a technology for packaging, distributing, and managing applications in a self-contained unit (i.e., “containers”). Containers house everything an app needs to run, and this isolation makes them lightweight, portable, and consistent. Since multiple containers can run on the same IBB, they share the required computing resources (CPU, memory, etc.). cloud-native The IBB consists of three main parts: , , and . These parts function together to make deploying and managing containerized apps easier and more secure. Operating System (OS) Administration IBB Apps (OS) Operating System Like a great deal of cloud-native computing environments, IBB runs on Linux, either on bare metal hardware or on a suitable Virtual Machine. The OS layer of the IBB also includes the open-source Kubernetes (often known as k8s) orchestration platform that manages IBB App containers. The OS layer of the IBB also includes other open-source software to further automate the management of IBB Apps. Administration The admin area of the IBB provides the tools for administrators to install and manage containerized applications. This includes software for the management of IBB Apps installed in the IBB, as well as user access and security policies and management. These admin tools provide admins access to the IBB remotely, using secure proxying mechanisms. IBB Apps These are the Apps and services provided by Independent Software Vendors (ISVs) that are installed in the IBB by admin users using the Admin tools provided. Each IBB App exists in its own container environment and thus operates separately from other containers (as if in its own hardware environment). Each IBB App communicates with other IBB Apps using IP networking with the help of IBB orchestration. Improving Stakeholder Experience IBB implementation improves the experience for all stakeholders because it simplifies the integration process. Currently, building owners and managers like Sarah need to employ capable folks with specialized knowledge to get things to work together. The process is complex, time-consuming, and expensive. The IBB takes the complexity out of the process by facilitating plug-and-play workflows. Let’s see how this works by following the process of installing and configuring an IBB using two different personas. IBB Installation Both HVAC and IT engineers can use familiar workflows and tools when installing and configuring an IBB. Here are the steps for installing an IBB for an HVAC Engineer and a DevOps: —Jake is tasked with installing a physical IBB device. He orders a suitably specified IBB-compatible device from his trusted vendor (CPU, memory, storage, etc.), takes it to the site, fastens it to a wall, connects it to the network, and on his browser, navigates to the IBB’s address and the IBB “Welcome” page. Jake (HVAC Engineer) —Mandy is tasked to install an IBB in a Virtual Machine on-prem. She navigates to the IBB repository on GitHub, looks over the IBB installation instructions, downloads the code, installs the IBB in the VM using her standard DevOps tools, and navigates to the IBB’s address and to the IBB “Welcome” page. Mandy (DevOps) Both Jake and Mandy were able to work in ways comfortable with their respective experience and skillset to achieve similar results; Jake through physical “box” installation that he was comfortable with, and Mandy used online “virtual” tools she uses daily. These flexible workflows and tools speed up the integration process. IBB Configuration Once installed, Jake and Mandy will need to configure the IBB to their specific needs for the building. On the IBB “Welcome” page, Jake/Mandy find a list of management platforms that support the IBB. They select the platform being used for their building project. In this example, they choose . Next, they login into the portal. The IBB is now installed and configured to the appropriate management platform. Acme X Cloud Acme X Cloud Acme X Cloud Now, let’s continue the configuration, considering Jake’s workflow. App Installation Once the configuration is complete, Jake can install and manage applications. He begins by choosing the “Install IBB App” option in the management platform (i.e., ). Next, he selects the app he wants to install. In this case, he wants to install a Haystack IDL (Independent Data Layer). Jake configures the app as necessary. The IDL app is installed, and Jake is presented with its UI. Acme X App Integration Next, Jake wants to install a dashboard required for the IDL. He uses the same IBB management system to install and configure the dashboard. The dashboard is then automatically connected to the IDL and runs the way Jake configured it. That is, the dashboard is running in the IBB, and it’s also connected to the IDL because they have compatible capabilities. Both Jake and Mandy can work efficiently and productively using their own skills and knowledge. Jake knows the apps he installed are compatible and already comply with IT policies. Mandy knows that the IBB is either a well-managed physical device or a virtual device she herself can oversee. More importantly, both engineers work within the purview of their own skill set. That is, they need not know anything about what the other does. In this way, the IBB helps ameliorate the industry’s skills gap. Instead of retooling our entire workforce, we can retool the way we interface with building systems. Vendors and End Users As was stated earlier, the idea of cloud-native architecture and containerization isn’t new; it’s only newly applied to the building automation industry. For years, app developers and the IT industry have built massive ecosystems that support and expand these technologies. Every time you use the Internet or your smartphone, you are using cloud-native. Everyone benefits, and now buildings can reap these benefits with the IBB. For example, mobile app developers follow common standards and protocols within both the iOS and Android platforms. The standards give developers dependable and consistent guidelines that make app deployment easy. Moreover, markets like Apple Store and Google Play ensure these standards are followed. Customers who download these apps can trust they are secure, reliable, and compatible with their devices. There’s no need to call someone to integrate your Instagram app to your iPhone. It just works. Now, contrast the above with today’s automation industry workflows, where thousands of vendors and developers create apps built with a disparate collection of proprietary standards, protocols, and guidelines that run on different platforms. Some are cloud-native, but most aren’t. With the support of vendors and the automation community, we can adopt the IBB and cloud-native architecture to create a collaborative ecosystem that would unleash the functionality and creativity of the entire industry. Conclusion The IBB not only holds the promise of streamlined integration and enhanced efficiency for the smart buildings industry, but it also addresses the very frustrations experienced by stakeholders like Sarah. For her, the dream of plug-and-play apps for her building is in reach. The IBB will result in a disruption to the entire industry by changing the way we develop, deploy, and manage our apps and data. Cloud-native offers the freedom and power our industry needs to leap forward and meet Sarah’s expectations. Moreover, the IBB’s benefits ultimately trickle down to the building’s users, tenants, and occupants. Also published . here

Introductory Guide to the Interoperable Building Box (IBB)

In my , I have shown a way to unify the implementation of the most well-known graph-traversal algorithms. Now, let's make it more visually appealing and look into the performance differences. last post The story behind A few years ago, Yandex organized a contest called with an enticing prize: a ticket to a . The contest resembled a game, with participants tasked with finding optimal routes on a map and optimizing delivery using robotic couriers. Robots Couriers closed self-driving conference for professionals As I delved into the topic, I discovered that despite route finding being a solved problem, it continued to interest the professional game development community. Between 2010 and 2020, engineers , particularly beneficial for AAA games with massive maps. Reading on these optimizations was an exciting experience. made significant optimizations to the A* algorithm articles and research papers Furthermore, the contest requirements were designed to enable easy assessment of program outputs by the contest’s testing system. As a result, there was little emphasis on visualization. I found exploring this field intriguing and developing a small application that uses well-known graph algorithms to find routes on a grid map. To visualize my findings, I employed the SFML graphics library. Goal This project builds upon one of , where I demonstrated that four well-known path-finding algorithms (BFS, DFS, Dijkstra's, and A*) are not fundamentally different and can be implemented in a universal way. However, it was challenging to showcase significant performance differences among these algorithms in that project. my previous endeavors In this article, I aim to use improved test data and design something visually exciting. While the Yandex Contest task mentioned earlier aligns well with my goals, I will not solve their specific problem here since it heavily relies on their test system, which is currently unavailable. Instead, I will extract general ideas for input parameters from that contest and create my own implementation. Imaginary world Imagine a technically advanced and innovative city where the future has arrived long ago. In this city, the majority of orders are delivered by courier robots, and it has become a rarity for a person to deliver an order from a cafe. In this task, we invite you to participate in finding optimal routes to deliver orders efficiently. Let's envision the city as an N × N map. For simplicity, we assume that each robot occupies exactly one cell, and each cell can either be passable or not for the robots. In one step, a robot can move in any of the four cardinal directions (up, down, left, or right) if the target cell is free. And I'm of the original task: ignoring the rest At the beginning of the test, you need to output the number of robots you want to use to deliver orders and their initial coordinates. The construction of each robot will cost Costc rubles. Next, T iterations of the simulation will be performed. One iteration represents one virtual minute and consists of 60 seconds. At each iteration, your program will be given the number of new orders, and in response, the program should tell you what actions each robot performs (60 actions per robot). For each successfully delivered order, you will receive max(0, MaxTips - DeliveryTime) dollars in tips, where MaxTips is the maximum number of tips for one order, and DeliveryTime is the time from the moment the order appeared to its delivery in seconds. The total number of points that you earn in one test is calculated by the formula TotalTips - R × Costc, where TotalTips is the total number of tips earned, R is the number of robots used, Costc is the cost of building one robot. The Costc and MaxTips values are set in each test. If you earned less tips than you spent on making robots, your total points will be 0. You will also receive 0 points for the test if you perform any incorrect action. Input The program uses standard input to read the parameters. This approach allows us to specify test data of various complexities using input files. The first line of input contains three natural numbers: N (the size of the city map), MaxTips (the maximum number of tips per order), and Costc (the cost of building one robot). I ignored both MaxTips and Costc parameters for my first implementation and maybe will consider that in the future. Following that, each of the next N lines contains N characters representing the city map. Each string can consist of two types of characters: '#' - indicates a cell occupied by an obstacle. '.' - indicates a free space. Next, you will be provided with two natural numbers: T and D (T ≤ 100,000, D ≤ 10,000,000). T represents the number of interaction iterations, and D represents the total number of orders. Output Your task is to visualize the map and the optimal routes using the SFML graphics library. Modelling the maps I'm fond of maps represented as a grid of cells. Thus, I prefer to render all the results and map them as a grid on cell by cell basis. There is also the option to execute path search right on the grid without using any additional data structure (and I have implemented this as well for learning purposes: see in code). But because of a grid, it is easy to represent a map as a graph in one way or another. I prefer to use an adjacency list of cells for most of the algorithms like BFS, Dijkstra's, and A-Star. For algorithms like Bellman-Ford, it may make sense to use an Edges List instead of an Adjacency List. That's why if you explore the codebase, then you will find all of it, and they all are working examples. To split the logic and responsibility, I have a entity that is responsible for executing path finding according to the orders and tasks configuration that is specified via the file and related map files.

    "map___": "../../data/maps/test_07_partially_blocked_map",
    ... Note that "map_” "map__" etc. are not really configuration properties. They are ignored during the application run. Since there is no way to comment on the part of the JSON file, I use underlining in the property name so it can stay in the config file but not be used. looks like this: The map file 25 50 150

6 6 4 20 This is one of the simplest examples that contain either blocked or not blocked cells. I have prepared a lot of various examples of input parameters and test data. Starting from very small parts that let you debug and learn the code, finishing with a huge piece of map (from the real existing city) that allows us to measure the performance of a Graph algorithm. How do we draw such maps? When a map contains only cells with binary state (either blocked or non-blocked), this basically means that any edge of a graph either exists or not. To find a path in the graph, we have to represent it efficiently. Like in my previous post, I have used an with the relationship as Vector[NodeId]->points to->Vector[Neighbour Nodes]: adjacency list typedef std::vector<std::vector<std::shared_ptr<Cell>>> Graph; When we exploring grids it's not really necessary to use graphs at all. We are capable to traverse grid using BFS/DFS algorithms cell by cell without thinking about edges. See method for example. _GetPathByBFSOnGrid First, the initialization code reads the file and converts it into row by row and column by column: the grid bool RectangularMap::LoadMap(const std::string& filepath, bool shadow)
{
...
  // Fill the grid.
  _verticesNumber = 0;
  for (int row = 0; row < _height; row++)
  {
    ...
    for (int col = 0; col < _width; col++)
    {
      int x = col;
      int y = row;
      if (line[col] == BLOCK_CELL)
      {
        // Create a shared pointer here to safely pass pointers between the classes.
        _grid[row][col] = std::make_shared<Cell>(x, y, line[col], blockColor, shadow, _scaleFactor);
      }
      else
      {
        ...
      }
    }
  }

  // Make a graph
  InitialiseGraph();
...
} Then, it creates an actual graph as : an adjacency list void RectangularMap::InitialiseGraph()
{
  MapBase::InitialiseGraph();
  ...
  unordered_set<int> visited;

  for (int rr = 0; rr < _grid.size(); rr++)
  {
    for (int cc = 0; cc < _grid[rr].size(); cc++)
    {
      if (_grid[rr][cc]->GetId() > -1)
      {
        for (int i = 0; i < 4; i++)
        {
          int r = rr + dr[i];
          int c = cc + dc[i];

          if (r >= 0 && c >= 0 && r < _width && c < _height &&
              _grid[r][c]->GetId() > -1)
          {
            if (_isNegativeWeighten)
            {
              ...
            }
            else
            {
              _adjacencyList[_grid[rr][cc]->GetId()].push_back(_grid[r][c]);
            }
          }
        }
      }
    }
  }
} Grid representation is useful to draw on the screen using the SFML library. We can draw (this is exactly what I do for small maps): by creating a geometric object ...
for (int j = _visibleTopLeftY; j < _visibleBottomRightY; j++)
{
  for (int i = _visibleTopLeftX; i < _visibleBottomRightX; i++)
  {
    _grid[j][i]->Draw(_window, _scaleFactor);
  }
}
...
sf::RectangleShape tile;
tile.setSize(sf::Vector2f(_cellSize - 5, _cellSize - 5));
tile.setPosition(sf::Vector2f(_x * _cellSize, _y * _cellSize));
tile.setFillColor(_color);
window.draw(tile); Or we can do it for larger maps: efficiently pixel by pixel sf::Uint8* pixels = new sf::Uint8[_width * _height * 4];

for (int j = _visibleTopLeftY; j < _visibleBottomRightY; j++)
{
  for (int i = _visibleTopLeftX; i < _visibleBottomRightX; i++)
  {
    int index = (_grid[j][i]->GetY() * _width + _grid[j][i]->GetX());

    sf::Color color = _grid[j][i]->GetColor();
    pixels[index * 4] = color.r;
    pixels[index * 4 + 1] = color.g;
    pixels[index * 4 + 2] = color.b;
    pixels[index * 4 + 3] = color.a;
  }
}

sf::Texture texture;
texture.create(_width, _height);
texture.update(pixels);
sf::Sprite sprite;
sprite.setTexture(texture);
sprite.setScale(cellSize, cellSize);
_window.draw(sprite); Finally, let's see what a map defined by file would look like. Originally, the file defined this: test_25_xmax ..............C.................
..............#.................

.............###................
.............###................
.............###................ And a map renderred with SFML looks like this: Because I wanted all of that to be controlled by the user with the keyboard, I left all the user-behavior logic in the . I like to call it “Controller” logic. main.cpp SFML library makes it very easy to handle keyboard events: while (window.isOpen())
{
  Event event;
  while (window.pollEvent(event))
  {
    if (event.type == Event::Closed)
      window.close();

    if (event.type == Event::KeyPressed && event.key.code == Keyboard::Space)
    {
      ... Do what you need here
    }
  }
} The main idea is for user triggers (press of a SPACE button) to read the map file and rendering the map, and then by a second trigger (second press of a SPACE button) to load the routing task and calculate the shortest path between two points on the map: ...
if (navigator->IsReady())
{
  navigator->Navigate(); // Finding route between two points
}
else
{
  if (map->IsReady()) // Second SPACE press runs the routing
  {
    skipReRendering = true;
    if (navigator->LoadTasks(filepath))
    {
      navigator->SetMap(map);
    }
  }
  else // Load and draw map
  {
    drawLoading(window, font);
    if (!map->LoadMap(filepath, shadowed))
    {
      return 0;
    }
    drawProcessing(window, font);
  }
}
... We need to go deeper I wanted to play with more Graph algorithms, and they all have their limitations, so I decided to implement multi-color maps that can be represented by multi-weighted graphs. Every cell is colored, and the color means that the edge not only exists but also applies some weight (or fee, or fine, you name it). So, the edge might be blocked, half blocked, not blocked, ... you got the idea. Thus, I have implemented multi-color maps that look more joyful and look like a game-ready (example from file ): test_31_multi_weight_graph_map Some of the configuration files contain more complex maps from really existing cities, like : test_29_yandex_weighten_real_map As a challenge, now we should handle maps with very flexible configuration. essentially contains a lot of logic inside, including all the graph algorithms and even more than needed (because I like to play with things, even if it's not particularly useful for now). RectangularMap.cpp I have implemented , , , algorithms, and a number of additional "utility" algorithms like Topological Sort, Single Source Path, that are not useful for the current application state (because they work on Directly Acyclic Graphs, which are not type of Graphs I currently use), but I have some ideas to use it in future improvements. BFS#Line 598 Dijkstra#Line 299 A-Star#Line 356 Bellman-Ford#Line 428 I didn't polish all the code and didn't get it ideal enough, but it allows me (and, I hope, will allow you) to play with the code and compare performance metrics. Sorry about some commented lines here and there, maybe some dirty code...it's all way of learning :). To grasp an idea of what's inside, I recommend you review the . RectangularMap.h There are also some fun features, like a Focus feature that allows one to render only a particular part of a map. It changes focus by re-rendering the necessary part using the when the user presses the PgDown or PgUp buttons. It is pretty easy to improve this feature and implement "Zoom" functionality. Take it as a homework, if you like it. Observer pattern Focus feature with map file in work: test_29_yandex_weighten_real_map Classes diagram looks like this: Run and play I believe the most joyful part is just running this little application is playing with variations of its configuration and algorithms. You can do a lot of experiments by using various map files as input parameters with different test data as well as change the logic in the code. After starting, you need to press SPACE an application will render a map according to the configuration file, and it makes a lot of sense to start exploring from the simplest test cases and moving forward to the most complex ones. Pressing SPACE one more time executes the routing algorithms and finds the path between the start and the nearest order. BTW, It's not yet done, but it is easy to implement reading all the rest of the orders available in map configuration files and execute pathfinding to all of them. Here is the route found on the map defined by file : test_18_yandex_super_high_res It is also capable of finding routes in the maps that simulate existing cities, like : test_29_yandex_weighten_real_map Finding efficient paths between two coordinates becomes challenging for algorithms like BFS but can be easily done by A-star. Based on the cells found in the map configuration files, the application will treat the map as a weighted or non-weighted graph and will select the right algorithm for it (and you can easily change this as well). It's easy to see the difference between BFS and A-Star performance: Final words With this, I want to leave you alone and let you play with these code examples. I hope you will find it fascinating and will learn a lot from it. Stay tuned!

Table of contents What is Vite? How does Vite work? Why use Vite over CRA? Performance Hot Module Replacement(HMR) Native ECMAscript module support Rich Features Prerequisites Creating a Project with Vite Conclusion Create React App (CRA) has long been the go-to tool for many developers of all skill levels when it comes to constructing a React app (beginners, intermediate and even experts). It does, however, have some significant drawbacks, which are speed and performance. It is well known that CRA can be somewhat slow while building a project and setting up a development server, requiring around 5-10 minutes (depending on factors like hard disks, and internet connectivity issues). Time typically adds up, which is why I'm going to introduce you to a tool called . Vite is a build tool similar to Webpack (CRA uses Webpack beneath the hood). More information is available ).) Vite here In this article, I'll walk you through the process of building a React App with Vite. You will learn the differences between CRA and Vite, as well as some of its features and benefits, and also how to create a React App with Vite. What is Vite? Vite, pronounced , like "veet" is the next generation in frontend tooling. It focuses on speed and performance by improving the development experience for modern web projects. /vit/ Vite is created by Evan You, who is the creator of Vue.js, but it's not a Vue-only tool. It can be used for React, Preact, Svelte, Vue, Vanilla JS, and LitElements. It consists of two major parts: A dev server which provides support for Hot Module Replacement (HMR) for updating modules during the execution of the application. When changes are made to the source code of an application, only the changes are updated, rather than the entire application. This feature helps speed up development time. A build command that bundles your code with Rollup, pre-configured to output highly optimised static assets for production. How does Vite work? At its core, Vite does 2 things: Serve your code locally during development. Bundle your Javascript, CSS and other assets together for production. There are other tools(bundlers) that do the same thing, such as webpack, Parcel and Rollup, so what makes Vite different? The problem with the tools mentioned above is that they have to build everything on every save, and if you have a very large application, that could take several minutes every time you save, even with Hot reloading in some frameworks, the update speed gets significantly slower as you add more code and dependencies to the app. Vite has taken a different approach to this, kind of a reverse approach. Vite starts the server right away, takes the dependencies that don't change often, and pre-bundles them using . esbuild is a Javascript build tool written in Go, which pre-bundles dependencies 10-100 times faster than Javascript-based bundlers. Esbuild Let's take a look at the illustrations below to get a better understanding of how it works. The above diagram represents a traditional bundle-based development server, where we have an entry point, the possible routes and all the modules, which are then bundled together, and then the development server is ready. Vite, on the other hand, uses route-based code-splitting to figure out what parts of the code actually need to be loaded, and doesn't have to pre-bundle everything. Vite serves the source code using native ES Module support in modern browsers. This lets the browser take the job of bundling in development, which consequently makes your code to load instantly, no matter how large the app is. It also supports Hot Module Replacement for an extremely fast feedback loop during development. When building for production, Vite uses Rollup under the hood, so you don't have to worry about configuring it. Why use Vite over CRA? You may be asking why you should use Vite now that we've covered what it is and how it works. We've gone through a few benefits in the previous section, so I will just highlight them here. Performance Pre-bundling with ESbuild makes it 10 to 100 times faster than using any other JS bundler. This helps improve page speed and convert CommonJS / UMD modules to ESM. Hot Module Replacement(HMR) Vite uses HMR capabilities to keep track of changes in your application without reloading the full page. With the HMR API, the browser will only load the modified section of the page and still retain the application's state. You don't need to manually set these up - when you create an app via , the selected templates would have these pre-configured for you already. create-vite Native ECMAscript module support Vite supports ES modules natively. It allows you to develop for the browser with bare imports like Typescript and it converts them into properly versioned imports on build. Rich Features Out-of-the-box support for TypeScript, JSX, CSS and more. Check out other Features . here Prerequisites Before using Vite, you'll need a couple of prerequisites: or higher Node.js version 14.18 Package manager - or Npm Yarn Compatible browser for development The third requirement is a browser that supports . You can check to see if your browser is supported by visiting: . dynamic imports caniuse.com/es6-module-dynamic-import Most modern browsers are supported, with the exceptions being Internet Explorer, Opera Mini, and the Baidu browsers. But if you're on a somewhat recent version of Chrome, Edge, Safari, or Firefox, you should be all set. Creating a Project with Vite To application, open your terminal and navigate to the folder where you want to save the Vite program. Then run this command: create a Vite npm create vite@latest You'll be prompted to select a framework and a variant(template). In our case, we'll be using React, so select React. You can also directly specify the template you want to use and the project name in one single line: npm create vite@latest my-react-app --template react Note: is the name of the Vite application that we want to create. You can change it to whatever name you prefer. my-react-app Next, run the following commands in the terminal cd my-react-app
npm install
npm run dev Moving on... Running the above command will start the development server. Then open your browser and enter . http://localhost:3000 You should see a React logo with a counter and a button, as shown below: Conclusion There we go! We've looked at what Vite is, how it works, and some of its features. We also learned how to set up applications using Vite. For this project, the create vite app command was set up in 10 seconds. After which I ran to install dependencies, which took 35 seconds. So, all in all, the project was set up in 45 seconds. Which I'm sure you'll agree is way faster than CRA ;-) npm install I would love to hear your thoughts in the comments section, and if you enjoyed this post or found it insightful, kindly share it with your friends and colleagues. Also, consider subscribing to my blog. Till next time, thanks for reading, and happy coding! Before you go, here are some to check out. community-maintained templates Also published here.

The social media giant has notified affectees and also shared details of the 400 malicious apps that were stealing users' information to Apple Inc. and Google parent Alphabet Inc. so they're removed from their app stores. Outside of the security breach, the internet was busy discussing Facebook's lofty attempts at bringing the metaverse to the masses. The company's metaverse app Horizon Worlds is so bad that even Facebook's own employees don’t like it, The Verge reports. What's worse is that the exec in charge of building and growing Horizon Worlds is forcing employees to plug into the app and "fall in love" with it. It's still far too early to tell what the metaverse will evolve into, and as this New York Times reporter correctly points out, explaining the metaverse through the lens of Horizon Worlds would be like describing the internet from the lens of AOL chatrooms (for the non-Boomers, AOL was an instant messenger that was eventually replaced by social media). Still, the reporter's overall impression of Horizon Worlds was positive (far more than Facebook's own employees) even though she met a lot more children than she had anticipated. Facebook founder Mark Zuckerberg is already betting his all on the potential of the metaverse, and with the Connect event right around the corner, we'll get to hear more about the future of the industry from the CEO himself.
