karax

The frontend uses Karax, which is my favorite frontend/SPA library in any language. It is an absolute joy to use, even if it's a bit rough around the edges. https://github.com/karaxnim/karax

I have used Nim for personal projects for 6 years now and it continues to surprise me on how well versed it is for many problem domains. I am fond of it's SPA framework, karax https://github.com/karaxnim/karax for which I wrote a translation utility https://github.com/nim-lang-cn/html2karax Latest Nimv2 release candidate has improved in the ergonomics and syntax that affect compilation to js, so I was able to cleanup my webapp's code to be less verbose. On GPU programming there has been a few projects that touch GPU programming, most notably https://github.com/treeform/shady

It's great to hear Nim in production stories! > I feel like Nim made me fall in love with programming again. Same. It's just so frictionless and productive, and you know your code will run on basically any platform in a nice, efficient, self contained executable. For me it's a language of sensible defaults. Speed and safety first, and opt-in machine level control. Want to target that obscure microcontroller? No worries: https://github.com/PMunch/ratel. Want to use Unreal? Sure: https://github.com/jmgomez/NimForUE. Want to target the web? Native React support with https://github.com/andreaferretti/react.nim or web apps with https://github.com/karaxnim/karax. The list goes on! https://github.com/nim-lang/Nim/wiki/Curated-Packages But, what if you want to use that battle tested C++ library? Nim can compile to C++ so you have native ABI FFI!

> the real killer feature to me is the javascript target Agree, this is amazing because you can share code and data structures between front and backend (for example: https://github.com/karaxnim/karax). Also, it's really nice having high level stuff like metaprogramming and static typing spanning both targets. Things like reading a spec file and generating statically checked APIs for server/client is straightforward, which opens up a lot of possibilities.

I don’t know about other web-guides. Nim’s official website is made with Nim and available at Github[0], but it has become at bit more complicated after they switched to Karax[1]. Jester’s tests gives a good view on the routing procedures[2]. The official tutorials[3] are pretty good, when you get the grab on how to ”decode” them. For web development with websockets and microservices I would suggest you to have a look at the Redis package[4], and @treeform’s Websocket[5] and JsonParsing-packet[6].

Builtin templates in Nim are awesome but since then, there is the possibility to render pages server-side with karax: https://github.com/karaxnim/karax Check my project that converts a static web page to ready to use karax DSL code: https://github.com/nim-lang-cn/html2karax

Karax [1] being Nim's SPA framework that also supports server side rendering. [1]: https://github.com/karaxnim/karax

`buildHtml` is a macro, the code passed to it via it's invocation (the 'colon-delimited indented code blocks') is then transformed as explained in the readme https://github.com/karaxnim/karax#hello-world and compiled. Macros are explained in the manual https://nim-lang.github.io/Nim/manual.html#macros

(Author here) Thanks! The inputs aren't sanitized in this example, but the output (the generated HTML) actually is in this case. Specifically this part: text ": " & sentMessage.getStr() The `text` function in the Karax DSL is actually escaped once it is converted to a string, see https://github.com/karaxnim/karax/blob/c71bc927494418c3f52f9... for the implementation if you are curious. There is a way to render raw HTML using `verbatim` instead of `text` in Karax. So in this case, I believe it would be protected against XSS to some extent, but I obviously haven't done an in depth security check for a demo/simple project. There are plenty of other potential issues as well (username collisions, websocket errors, user lists) but I judged those to be out of the scope of a simple project like this.

Well no language is perfect, but Nim can be used in almost every domain because of it's compilation targets(C, C++, JS) and it's fast compile times(who needs interpretation when compile times are that fast!): * Shell scripting, I still assume most people will just use Bash tho: https://github.com/Vindaar/shell * Frontend: https://github.com/karaxnim/karax or you could bind to an existing JS library. * Backend: For something Flask-like: https://github.com/dom96/jester or something with more defaults https://github.com/planety/prologue * Scientific computing: the wonderful SciNim https://github.com/SciNim * Blockchain: Status has some of the biggest Nim codebases currently in production https://github.com/status-im?q=&type=&language=nim&sort= * Gamedev: Also used in production: https://github.com/pragmagic/godot-nim and due to easy C

Templating as in Jinja? I'm using Karax (https://github.com/karaxnim/karax#server-side-html-rendering) and it's awesome.

For me, it's a full stack language, write the frontent with karax https://github.com/pragmagic/karax or react bindings https://github.com/kristianmandrup/react-16.nim and backend in pure nim with any of the available web frameworks (jester/prologue/looper) and orms (ormin/norm) and share code and type declaration between the two.
