Reason for the article: Static HTML documents generation Email body generation : Parameters to compare Straightforward usage Minimum complexity Minimum dependencies I went through a ton of articles and questions on stack overflow, stack exchange, here are some : options how to generate HTML documents RazorEngine RazorLight HtmlContentBuilder Web app to call locally and render HTML on serverside Simple templating with keys replacing Handlebars.Net 1. RazorEngine While checking the approach I was not able to run it on .Net Core. It requires lots of dependencies and obsolete libraries. RazorEngine Knowing that everybody would avoid obsolete technologies and .Net framework libs I think going with this generator is not the right way. 2. RazorLight After some research, I was able to run the Razor engine using this library on “netstandard” library, please see the following code below. Pros: Powerful generation engine Cons: It brings lots of libraries in the dependencies The library is not official A latest valid working version is 2.0.0-rc.3 May require DevOps effort to make it work on the environments Requires next property inside PropertyGroup for the app which uses this library true < > PreserveCompilationContext </ > PreserveCompilationContext 3. HtmlContentBuilder is more suitable for dynamic HTML creation and requires lots of preparation to build actual HTML output. I do not see the benefits of using this library for current goals. HtmlContentBuilder 4. Web App to Call Locally and Render HTML on Serverside This idea died in my head at the very beginning, since to achieve this we needed to: Create a separate resource using aspnet core, asp.net framework or other Maintain this resource Maintain dispatcher/client for the resource Make calls to this service endpoints locally from any place you need to generate an HTML document Send data required for rendering in the body of each request or implement data retrieving before generating an HTML 5. Simple Templating Here is the code example with the simplest and atomic approach implemented in .net core console application: Key points: No dependencies and external apps required It may be implemented in any place and will not complicate the system Nothing new for C# developer Each HTML builder is atomic and knows what to build and where to place data It may have the functionality to get the template from a file It may call some additional builders to get HTML from there (f.e. for header and footer) It may have the functionality to get some common HTML or CSS from another file 6. Handlebars.Net After all the previous disappointing findings I started locking in using JS frameworks to do the generation of documents, that is how I found but written fully in .NET Handlebars.js . So Handlebars.Net is a really easy and fast way to do documents generation because it doesn't use any scripting engine to run a Javascript library; it compiles Handlebars templates directly to . It also mimics the JS library's API as closely as possible. IL bytecode Since Handlebars.js has a big community and a long story you will be able to find answers to your questions to build a valid HTML. The link to their Github repo is . here Conclusion The simplest and fastest way for simple files generation would be to go with simple templating which will not bring new dependencies into the project. On the other hand, people who know Razor may be easier to go with a powerful Razor engine via RazorLight, but it may require DevOps effort to make sure dependent libraries are in place in the environments. And I think the easiest and most extendable way would be which is straightforward in usage. Handlebars.Net In addition All these findings can be applied not only to generate HTML files, but for XML files and any plain text documents. Also, this article will be useful for those who are looking for a way to generate PDF documents since data sources for the generation of PDF files may be HTML string. A good topic to explore next would be: "How to convert HTML to PDF." Lead image courtesy of Nathan da Silva on Unsplash.
