Meet the Winners of Startups in North and Central America

DEXs (decentralized exchanges) have become increasingly popular within the cryptocurrency world in recent months, as they provide traders with an alternative to centralized exchanges that essentially hold and control user funds. Today’s popular DEXs are still blockchain specific, with Ethereum-based solutions leading the charge; and has since exploded both in popularity and valuation, with a current market cap of around $16 billion. Uniswap was deployed to the Ethereum mainnet back in November 2018 and is another leading DEX platform running on Ethereum. Binance Smart Chain and Polygon (formerly Matic) have since emerged with various DEX solutions on their respective blockchains, including PancakeSwap and QuickSwap, offering users alternatives to Ethereum’s sometimes high GAS fees and long transaction times. Sushiswap was later forked from Uniswap The Polkadot blockchain is the lovechild of once Ethereum core developer Gavin Wood and is one of the most exciting blockchains to have emerged in recent years; the ever-expanding Polkadot ecosystem has over 250 projects (including dApp platform Plasm, Smart Contract platform Moonbeam and Operating System parachain Clover) on its innovative parachain infrastructure that is supported by Substrate. Referred to as the ‘blockchain of blockchains', Polkadot enables private and public blockchain apps to exchange data in a trustless and decentralized environment. With the eyes of the blockchain community fixed on , there will undoubtedly be an influx of both platform participants and traders on the platform in the coming months. It, therefore, comes as no surprise that in order to give users a place to trade the various tokens that power projects built on Polkadot and it’s parachains. Polkadot’s crowd loan (PLO) events DEXs are today being built throughout the ecosystem Below are four promising platforms and protocols that offer Polkadot users decentralized token swapping functionality and a lot more besides. Polkadex With a mainnet launch scheduled for Q3-Q4 2021, Polkadex looks to bridge the gap between DEX and CEX, enabling users to utilize features that are traditionally only available on centralized platforms, such as margin trading, but in the self-sovereign DEX environment that sees them keep complete control of their funds at all times. Built on Substrate, the order book-based DEX is more than just a simple swap protocol, as it also enables users to place market orders and limit buys/sells, as well as trade their assets for fiat or even delegate their assets to third parties for use with bot trading and the likes. Central products and features within the Polkadex suite include: Orderbook The Polkadex Orderbook can support up to 500,000 transactions per second with low latency, made possible using its unique TEE architecture, and is the flagship product of the Polkadex platform. The order book supports both Ethereum and Substrate-based assets; the Polkadex team will connect to Ethereum via Snowfork, a trustless bridge, and, once complete, users will be able to lock up their assets in Ethereum and trustlessly bridge liquidity to Polkadex. PolkaIDO Polkadex IDO is a one-stop-shop efficient solution for all the activities from conducting the fundraise to listing tokens on Polkadex exchange fully on-chain. The IDO platform will be the easiest way to deploy tokens and distribute them among IDO participants. Teams will receive an end-to-end product that allows them to create tokens, bridge to other networks, list in the Orderbook, conduct IDOs and also finally migrate to their own blockchains later on in the project’s development. It’s a full governance-driven DAO using on-chain randomness to select lucky participants. Polkapool Polkapool tackles the often unmanageable Gas fees and transaction times that plague traders on the Ethereum network with the introduction of feeless swaps; as a DEX AMM (automated market maker) inspired product, Polkapool also eliminates front-running with fast transaction fees on the Polkadot blockchain. Polkapool will also take advantage of Polkadex’s cross-chain bridges and allows for interoperability between tokens and liquidity on different blockchain networks. Polkadex’s “Fluid Switch Protocol” helps investors to park funds and earn interest as part of its Perpetual Liquidity Mining program powered by blockchain rewards, making sure that Polkadex can offer traders and liquidity providers continuous liquidity and eradicating slippage issues. Trading Bots + Fiat On-Ramp Polkadex low latency Orderbook also allows for high-frequency and algorithmic trading, with users able to set buy and sell orders through third-party bots whilst still retaining custody of their funds. Bots will handle both institutional and retail customers. Polkadex also plans to introduce a fiat on-ramp function with Polkadex Fiat, meaning that DeFi users will have more options to choose from when exchanging their assets. The platform aims to make powerful trading tools more accessible to DeFi users while maximizing liquidity and cross-chain support. Polkadex received funding from Web3 Open Grants Program and is also partnered with CMS, Cluster, Blocksync Ventures, Existential Capital, and others. “At Polkadex we are combining the benefits of centralized and decentralized exchanges to create a revolutionary decentralized cryptocurrency trading platform built for newcomers, experienced DeFi users and institutional traders alike.” Zenlink Zenlink is an exciting Polkadot-based cross-chain DEX that enables users to swap any crypto asset across Polkadot’s parachains seamlessly and safely. with the introduction of a powerful DEX module and aggregator that any Polkadot-based project can utilize for themselves. Zenlink aims to build a “cross-chain DEX network” Zenlink differs from others on this list, as it essentially has the power and functionality to connect the liquidity of all projects and parachains built on Polkadot; amongst the main products, Zenlink offers a pluggable DEX module that allows different parachains to have DEX capabilities with just one-click. Zenlink consists of two innovative core products: Zenlink DEX Protocol Zenlink DEX protocol is the underlying cross-chain DEX protocol for parachains to interoperate and share liquidity pools. It is built on the XCMP protocol developed by a team led by Gavin Wood, Founder of Polkadot. The cross-chain protocol on Polkadot can be compared to the traditional TCP/IP protocol. The XCMP protocol is similar to the data link layer on TCP/IP, which solves the transmission function of the indiscriminate perception protocol between each chain (route). Zenlink DEX Protocol is similar to the application layer on TCP/IP. As long as a parachain implements Zenlink DEX Protocol, it can share all the liquidity pool of parachains on Polkadot. Zenlink DEX Protocol introduces into the Polkadot ecosystem a simple yet powerful and highly versatile pluggable DEX Module, that gives parachain project teams the power to access and offer DEX capabilities to users. Notably, the ability to replace and upgrade Zenlink DEX modules means that systems can be easily customized and improved with minimal friction for project teams. The Zenlink DEX Protocol will be implemented in three forms: Module, WASM, and EVM. Cross-Chain Capability and Liquidity Sharing Once the Zenlink Module is deployed on a Polkadot-based platform or parachain in a “plug-and-pull” style, projects can connect with others and share liquidity across the entire network, representing an exciting move forward for the Polkadot ecosystem as a whole. Liquidity pools are formed in each parachain after deployment of the Zenlink Module, with a powerful DEX Aggregator then opening the liquidity pool across parachains to enable liquidity sharing between the DEX Module on different parachains. Zenlink promotes more overall growth in the ecosystem and encourages robust connections between Polkadot’s various parachains with the introduction of liquidity sharing capabilities; sharing of the DEX orderbooks across parachains also means a smooth and superior trading experience for users in the Polkadot ecosystem as the overall platform steps further into the limelight. to power the DeFi products that are being built with its cross-chain DEX modules. Zenlink also integrates Chainlink’s price oracles Zenlink DApp The Zenlink DApp is a front-end interactive product that ensures a smooth user journey and a “one-click” trading experience. By performing actions on the back end, such as path searches for trading pairs that may not yet be supported, the Zenlink DEX DApp takes the logic out of the hands of the user and enables a simple and unified trading experience with low slippage and rapid transaction finality. The Zenlink DEX Protocol and, having already partnered with several parachain , Plasm Network, Phala Network, and Math Chain, the Zenlink team are on a mission to unite the many pioneering projects being built on Polkadot in a bid to unlock the liquidity that is currently siloed within each of the parachains within the DOT ecosystem. The project has already received two Web3 Foundation grants, the second to develop the DEX smart contract implementation, which is open-source in line with Polkadot’s ethos of a decentralized web and also secured a $1.1M angel round of funding that was led by Continue Capital, Hashkey, D1 Ventures, IOSG Ventures, and Youbi Capital. will be integrated into Shiden and Bifrost soon according to recent team updates auction-winning projects such as ChainX “As an important protocol layer project in the Polkadot DeFi stack, Zenlink will play a key role in connecting the huge liquidity of the Polkadot DeFi ecosystem, such as helping parachain projects to deploy DEX and achieve liquidity sharing with one click, linking all DEX aggregation liquidity on the Polkadot.“ Polkaswap Hosted on the SORA 2.0 network, Polkswap’s DEX is another project supported by the Web3 Foundation Grants Program and it’s focus on interoperability looks to connect the rest of the blockchain development world with the Polkadot ecosystem as a non-custodial liquidity aggregator and cross-chain AMM DEX. Behind the colourful and friendly branding of Polkaswap sits a powerful product aiming to bridge the gap between the broader crypto landscape and the quickly growing Polkadot ecosystem; Users can add tokens from the Polkadot ecosystem as well as from other blockchains to the platform’s exchange, opening up a world of new trading opportunities for both ERC-20 tokens and assets from any other blockchain that can be connected to Polkadot. Built on Substrate with scalable Hyperledger Iroha v2 and written in Rust, Polkaswap looks to offer users rapid transaction finality and lower gas fees than Ethereum-based DEXs. Open Source Development Polkaswap’s codebase is open-source and anyone can add liquidity sources by making contributions to the Polkaswap codebase. The project has been contributed to by , a Japanese firm and “global technology company delivering blockchain-based solutions for enterprises, universities, and governments”. Soramitsu Polkaswap is constructed upon , which utilizes Substrate and includes bridges to many other blockchains, including Ethereum and Bitcoin. SORA Network is looking to have its own parachains for Polkadot and Kusama and will have its own set of validators in the future. The Soramitsu team are the developers behind SORA Network and have also developed solutions such as Kagome, a C++ implementation of the Polkadot Host, and the  C++ Filecoin implementation. They are also collaborating with the National Bank of Cambodia to develop Bakong, an integrated fintech payment system. SORA Network The PSWAP Token The native PSWAP token was introduced after community governance and serves as a utility and governance token used to reward liquidity providers on the platform. PSWAP tokens are burned with transactions and decrease in supply over time, with a 0.3% fee (the same as Uniswap) for every swap used to buy back tokens; new PSWAP tokens are minted to reward liquidity providers. Rewards to liquidity providers started at 100% of burned trading fees but will gradually be reduced to 35% of daily burned tokens after 5 years. Polkaswap’s native PSWAP token was not made publicly available via IDO but instead was rewarded to users who provided liquidity for specific Sora.farm pairs over several months. In total, 3.5 billion PSWAP tokens were issued as farming rewards, with further tokens distributed through the build-up of reserves in the token bonding curve for SORA v2 and issued as rewards to market makers on the Polkaswap DEX. Peer-to-peer fiat to crypto transactions and fee-less transactions are some of the releases outlined on the Polkswap roadmap in the coming months. “Polkaswap is a non custodial AMM DEX designed uniquely for the Polkadot ecosystem and the interoperable future. Polkaswap aims for liquidity, security, convenience and a user-friendly interface, where an immediate exchange of assets can take place.” KaruraSwap Karura is not only a DEX-focused platform being built within the Polkadot ecosystem but is a scalable, EVM-compatible DeFi suite that was founded by the . The platform offers an array of DeFi applications such as a trustless staking derivative named liquid KSM, a multi-collateralized stablecoin backed by cross-chain assets named kUSD, and an AMM DEX trading platform. The DEX specifically was successfully launched and near the end of July 2021. Acala Foundation went live for trading on Polkadot’s canary network Kusama Karura Swap between an expanded selection of token pairs away from centralized exchange listings. New tokens can be quickly added to Karura Swap through governance; fresh trading pair listings are approved through governance, and pairs can be added quickly to the platform without the need for intermediary or centralized involvement. Karura Swap's novel design that was inspired by the (first introduced by Uniswap) also allows for users to transact in illiquid markets, enabling the swap of any token to any other token in a single transaction provided there is a path between the two. allows for users to trade directly “constant product formula” TVL (total value locked) on , with an initial TVL of over $3.4 million USD locked in by utilizing a “Bootstrap feature,” which allows a liquidity sandbox for trading pairs. This warm-up period essentially encourages a pool to reach adequate liquidity before going live, also aiming to tackle frontrunning and market manipulation. KaruraSwap hit $35.65M on August 9th 2021 conducted by Kusama recently with 501,000 KSM  (equal to over $100 million USD at the time of writing) raised by the Karura and Polkadot communities. As part of what aims to be a complete DeFi package, Karura enables users to swap, borrow, lend, earn, and more all in one spot. Karura won the first Parachain Slot Auctions “Karura Apps offer the ability to trustlessly trade tokens without intermediaries through Karura Swap. Karura Swap is a trustless, automated market maker (AMM)-style decentralized exchange on the Karura network. Karura Swap supports the ability to trade native Substrate tokens and ERC-20 tokens.” Conclusion The future of Web3 is seemingly unstoppable, and the cryptocurrency world is sure to benefit from the various solutions and products explored above, with several pioneering projects now offering DEX functionality within the Polkadot ecosystem. Although some are offering different solutions than others, the overall goal to incentivize growth within the blockchain industry remains the same, and the above projects are shining examples of what can be achieved when utilizing both Polkadot’s and Kusama’s exciting infrastructure. What is the DEX solution on Polkadot that gets you most excited right now? Let me know on Twitter!

DEX on Polkadot? Here are 4 projects to Consider

In 2019, the of U.S. venture capital investments was $108 billion. In the same year, the federal government spent on research and development. value $131 billion These taxpayer dollars are earmarked to advance science and technology to fuel economic growth, improve competitiveness, solve social challenges, and of course, national defense. The government has done this for decades, so why don’t people mention this money when talking about startup funding? In a word, bureaucracy. Anyone who’s applied for or managed a grant understands how convoluted the process is. Some say it’s not worth the money, but others are working to change that. Sedale Turbovsky, a multi-time founder who was frustrated with the grant process, is one of those people. “I was the CEO of a clean-tech company that relied on grant funding to operate in the commercial vehicle industry. My team and I spent so much of our time working on a single grant, writing reports, and dealing with compliance that it cut away at our ability to create real impact in the market,” says Turbovsky. He realized that a private company might have a shot at improving public funding. The vision was to create a company that bridges the gap between government and startups, and the result is . Two years into its journey, the company has a simple application that matches startups to funding and a grant writer, and guides them through the process. OpenGrants.io Behind the scenes, the company built software and gathered a small army of grant writers to fuel the experience. The team is also working on a grant management system to support compliance headaches, which is expected to launch later this year. For Sedale, this is about more than efficiency. Historically, grants have been largely awarded to select stakeholders based on their connections and experience. As a bi-racial founder from a rural community, he knows firsthand how hard it is to get a company off the ground with limited access to resources. That’s why OpenGrants aims to literally open the door for minority-, woman- and veteran-owned companies, as well as other underrepresented groups. The hope is that more equitable public funding will help create companies that actually improve our society, instead of continuously funding incumbents. It's a concept everyone can agree on. The question now is whether they can pull it off.

On The Issues of Grant Process

Prisma, WunderGraph, graphqurl, GraphQL Voyager, and more. Discover the best GraphQL Dev Tools that can help you streamline your development workflow. From full stack development to schema visualization, to performance monitoring, these tools have got you covered. GraphQL has rapidly gained popularity in recent years, and is now used by major companies like Shopify, Pinterest, GitHub, and Twitter for their core businesses. The reason for this widespread adoption? By standardizing multiple techniques under one umbrella, the GraphQL spec saves developers time and resources that would otherwise be spent in reinventing wheels and then wiring them together. Plus, GraphQL can save you bandwidth, letting you access all relationships with a single query while giving you only the data you ask for — no more, no less. It offers fantastic development experience, with a strongly typed schema that makes describing the exact data you want or need, incredibly easy. In certain situations, it can even be the bandaid (in the form of a contract) that saves your project if you have organizational issues where your backend people don’t get along with your frontend people! There are plenty of gotchas to consider, from backend architecture to caching, security, and versioning. It’s just a complex language to develop for. But one thing GraphQL is not, is a silver bullet. Thankfully, the ecosystem around GraphQL is a burgeoning one, and there are many dev tools that can ameliorate these pain points and make life easier for you as a developer. Knowing the right tools is half the job when it comes to GraphQL, so I’ve put together a list of 10 that covers the spectrum of use-cases from schema visualization to full-stack development, to documentation, to testing. Let’s get right to it! The List 1. GraphiQL Getting started with GraphQL? This is probably the first tool you’ll ever use. is an open-source, lightweight, interactive in-browser IDE from the GraphQL Foundation. Any GraphQL API with a GraphiQL implementation makes it possible to try out queries and examine the schema to understand what the API can even do, without ever leaving your browser or writing code to interface with the API. GraphiQL To that end, GraphiQL supports the official GraphQL spec out-of-the-box and includes several fancy features like a visual query builder, API doc explorer, and intelligent auto-completion that is actually aware of the current GraphQL type schema, with live syntax + validation error highlighting. Taking inspiration from OpenGraph’s explorer, GraphiQL 2 has added a Doc Explorer, which provides a hierarchical view of the schema, making it easier to navigate and explore. Also present: tabs, variables, merging fragments, prettifying operation payloads, history, better-looking UI with themes, and more, out of the box. GraphiQL has been around for some time, but it was starting to get a little long in the tooth. GraphQL Playground had it beat in terms of UI/UX, and with its less technical debt, was easier to recommend. However, with the release of GraphiQL 2, this has changed. Playground is now part of the GraphQL Foundation and has been merged into GraphiQL 2, in a rare case of the sequel being better than the original movie. GraphiQL comes as a dependency you can add to your React projects ( ) with: and then render via components npm install graphiql Bear in mind that you’ll also need to have , , and installed as peer dependencies of graphiql. Or, you can just use , embedded into HTML. react react-dom graphql pre-bundled static assets from Jsdelivr/Unpkg 2. WunderGraph This is one of the most exciting new dev tools I’ve worked with. is a BFF/API Gateway that can do what we know as “federation” or “schema stitching”, but for your data sources, whether they’re SQL/NoSQL DB’s, OpenAPI REST or GraphQL APIs, Apollo Federations, or any other. . WunderGraph all Check out the full list here Here’s what a typical WunderGraph workflow looks like: You define your data dependencies in a config file (instead of putting them in your application code), the WunderGraph server introspects them individually, and namespaces and consolidates each into a virtual graph layer. You can then write GraphQL queries, or async resolvers in TypeScript (with for validation) to get any combination of data you need from the graph, composing different APIs and data sources together. If querying in GraphQL, you can use a special _join field to skip the burden of doing these in-code JOINs entirely. Zod If you’re using a React-based framework (like NextJS or Remix), or SolidJS, WunderGraph then generates fully typesafe data fetching hooks for you (using or under the hood) that you use on the frontend to access that data. No need to write and maintain your own types. Vercel’s SWR TanStack Query If not, the WunderGraph server (WunderNode) serves the result of each operation as JSON-RPC over good ol’ HTTP REST API endpoints, solving the security and caching issues of GraphQL in one fell swoop. Using WunderGraph lets you leverage GraphQL only during dev, getting you all the devex wins of GraphQL without any of its pain points. A win-win! At no point in this process do you ever need to expose a public GraphQL endpoint. WunderGraph uses persisted queries that apply the Stale-while-Revalidate model, and offers isomorphic typesafety. You could literally make changes to the server code, and see the changes in real time on the client. You can’t do better than that for devex. Plus, if you’d rather not use GraphQL at all, you can still do everything you want using TypeScript Operations alone, making WunderGraph a full stack dev tool that’s like tRPC…but supports GraphQL as a first-class citizen. 💡 The WunderGraph server responsible for codegen and serving the JSON-RPC endpoints is a Go + NodeJS server that can be deployed to anything that supports Dockerized images ( , or, if you want a fully-managed service, ). To know about deployment and much more, check out their docs . fly.io WunderGraph Cloud here 3. GraphQL Voyager is a developer tool for visualizing and exploring GraphQL APIs. Using it, you can represent any GraphQL API as an interactive graph. GraphQL Voyager This is an interesting one. It provides a clear, visual, interactive representation of the schema, making it great for understanding a system, onboarding new team members (ensuring that all team members have a shared understanding of how the API works) and just exploring relationships between data. GraphQL Voyager helps developers and stakeholders alike understand how the API works and what data is available. The latest release of GraphQL Voyager includes support for custom themes, the ability to collapse nodes in the schema, and improved accessibility. You can also now export the schema as a JSON or SDL file, making it easier to share updates with other developers, or use it in other tools. This also comes as a dependency you can add to React projects, and render via components. npm install --save graphql-voyager  
# or  
yarn add graphql-voyager 4. SpectaQL GraphQL simplifies documentation by having the schema itself be the “good enough” option for docs… but as any developer would tell you — there’s never a substitute for proper documentation that helps developers at all stages of the knowledge funnel. , then, is a Node.js library that addresses exactly this need. It auto-generates static documentation for a GraphQL schema for all Types, Fields, Queries, Mutations, Arguments and Subscriptions by default, and can even filter/hide any on demand. SpectaQL You install it as a dependency with: npm install spectaql  
# or  
yarn add spectaql Define a to specify how you’d like to generate your docs (Read more about that ) config.yml here And when ready, simply generate your docs with: npx spectaql config.yml Your generated documentation will be located in the public directory by default. You can either copy the generated HTML to your web server, write the output to somewhere else using the option, or add a flag and view your docs live by pointing your browser to . -t /path/to/ouputDir -D [http://localhost:4400/](http://localhost:4400/) 5. GraphQL Network Inspector The best example of how the tiniest things can make a huge difference to developer experience. The is an open-source tool (MIT License) that sits as a , adding a separate “GraphQL” tab to its dev tools so you can inspect every single GraphQL request — including support for batched and persisted queries. GraphQL Network Inspector Chrome extension It works with any GraphQL client (including Apollo and Relay), and lets you search and filter queries/mutations, copy request/response bodies with one click, and, most importantly : saves you the trouble of sifting through every payload in the Network tab (which would be like searching for a needle in a haystack; all requests there would be identical — made to the same URL) to understand what’s happening with your GraphQL queries, or how to even start optimizing them. 6. Postman is easily the go-to tool for API development/testing for millions of devs, helping them build, test, and document APIs. It provides an intuitive interface for making HTTP requests, organizing requests into collections, and automating workflows, with built-in integrations for GitHub, Slack, and Jenkins. Postman What’s of interest to us, though, is its built-in support for GraphQL. Using Postman’s GraphQL client, you can: Create and send GraphQL queries, mutations, and subscriptions using GraphQL variables and fragments, Analyze query response times and other performance metrics in real-time (particularly useful for benchmarking subscriptions) Export GraphQL operations as code snippets, or save them into a collection to reuse later, document and share with teammates, or publish it to the world via the , Postman Public API network Introspect a GraphQL endpoint to import a GraphQL schema, saving it for future querying. Explore the schema to see its fields, relations, and all scalar types possible. Postman’s GraphQL client is incredibly useful for just learning the technology, too, as developers get auto-completion while writing GraphQL queries/mutations/subscriptions, and the visual Query Builder lets you simply select fields from the Schema Explorer and generate these operations without writing any code at all. The UI, too, makes this intuitive — you can split panes to have the Schema Explorer, Query Builder, and the Response window all side-by-side, on the same screen. Also, Postman is particularly useful for API development teams that are working across multiple platforms and programming languages. Here’s an example: if you were using WunderGraph, you could generate and share a Postman Collection on-the-fly during development for your defined operations (and their WunderGraph-generated JSON-RPC API endpoints), making it easier to collaborate with other devs on projects. 7. Graphqurl is a nifty little CLI built by the Hasura team that’s essentially “cURL, but for GraphQL!” graphqurl This is one of my favorite tools. I particularly like using it to spin up a local instance of GraphiQL from the command line, on-demand, against any endpoint (with custom auth headers and everything) and get autocomplete with it, too. It’s an essential part of my GraphQL development workflow, making me significantly more efficient and productive. Installation npm install -g graphqurl Usage gq https://my-graphql-endpoint/graphql \  
-H 'Authorization: Bearer <token>' \  
-q 'query { table { column } }'  
  
# Or just open a GraphiQL instance with:  
  
gq https://my-graphql-endpoint/graphql -i You can also use as a Node.js library that you call from a lambda, for example. Find instructions for that . graphqurl here 8. Prisma is an open-source ORM (Object-Relational Mapping) tool that streamlines data modeling, migrations, and data fetching from MySQL, PostgreSQL & SQL Server databases — providing a type-safe database access layer for GraphQL servers. Prisma Why use Prisma? Well…GraphQL does indeed make querying data much simpler and more intuitive than REST APIs, but you still have to write resolvers that define your server actually fetches the needed data from the database. If you don’t know what you’re doing, it’s incredibly easy to write sub-optimal queries (fetches too many records at once, are too complex, too deeply nested, etc.) that have a high-performance cost. how That’s where Prisma comes in. As an ORM, it specializes in crafting queries with a strong focus on performance — using various optimizations like batching and caching under the hood to provide a default best-practices way to interface with each database it supports. Using Prisma ORM inside of your GraphQL resolvers to query a database, means you can rest assured you’ll get the most typesafe, performant, optimized data fetching possible, every single time. 9. GraphQL Faker is a well-known library for quickly testing and prototyping APIs with realistic mock data. If you’re building GraphQL APIs, does the same, speeding up your development cycle by quickly generating fake data (for the archetypes of eCommerce, Finance, Names/Addresses, Timestamps, and more) that conforms to your GraphQL schema. Faker.js [graphql-faker](https://github.com/IvanGoncharov/graphql-faker) You provide a GraphQL schema as SDL, and graphql-faker will allow you to define custom resolvers for fields in your schema, which means you can generate realistic fake data that matches your exact use case. Scalar types like strings and numbers are supported out of the box, as are more complex data structures like objects and arrays. GraphQL Faker runs as a local server (that can be called from your browser, cURL, graphqurl, or just your app.), and also provides an interactive GraphQL query editor with autocompletion (even for its and directives). @fake @examples It can even proxy an existing GraphQL API, and extend it with faked data! Installation npm install graphql-faker --save-dev Usage graphql-faker [options] [SDL file]  
# You can also open the interactive query editor like so:  
graphql-faker - open [SDL file] If you don’t provide an SDL schema, graphql-faker will just use a default. Learn more about the CLI and its usage . here 10. GraphQL Inspector is a dev tool for GraphQL that allows developers to validate, lint, and compare GraphQL schemas. It supports both SDL and AST formats. GraphQL Inspector It outputs a list of changes between two GraphQL schemas, and even lets you see a diffed view of the before and after. This helps identify potential breaking changes to your GraphQL schema before you deploy them to production. This is incredibly helpful if, for example, you’re adding a new field to your GraphQL schema, and want to make sure that it doesn’t break any existing queries or clients that rely on your API. Another cool feature is its Slack, Discord, and general webhooks integration, allowing you (and your team) to stay up to date on any change to the schema. Every change is precisely explained and marked as breaking, safe, or dangerous. What’s more, its can interface with your repo, and generate a list of all proposed changes to your GraphQL schema on every single PR, giving you all the information you need to know whether you should implement the changes or not. GitHub App The Right Tools for the Job As developers continue to embrace GraphQL ( — and climbing!), a plethora of powerful tools are emerging to simplify the development process — shoring up its gotchas and enhancing productivity. fourth most used API architecture in 2022 From query visualization with GraphQL Voyager, to WunderGraph as an API gateway that turns GraphQL into JSON-RPC in real-time, to testing and documentation with Postman and SpectaQL, these 10 development tools provide an arsenal of features to make the lives of GraphQL developers easier. Whether you’re an experienced GraphQL developer or just starting out, I hope this list has nudged you toward the tools you need to streamline your workflow, improve code quality, and deliver high-quality GraphQL APIs in less time.
