6699 :: Targeting JavaScript

• halloleo (orginal) [2020-08-20T06:15:11+02:00] view original

  I have played a little bit with nim (and the C backend) - and I like it.

  For me the opportunity comes up to use it in a small project (mangling some time-related tabular data). However the project has to target nodejs. My question is: How mature and up-to-date is the JavaScript backend of nim? Do people use it (apart from the demo game featured on the homepage)? How do nim packages work with the JavaScript backend?

  Thanks for any advice!

  It works well and is mature. However, only selected libraries work on it and "nim js" targets the JS a browser supports, including the DOM. nodejs support is provided via nim js -d:nodejs but we only support it for easier automated testing.

  Thanks heaps for the reply.

  And thanks for the info about pattern import for accessing JS libraries. Do we have any examples of wrappers for JS libraries (like e.g.d3.js)?

  Basically if it can run compile-time it runs on JavaScript, probably.

  Check the Wiki, everyone is welcome to improve it, is not perfect.

  Hey, the comparison with Typescript is quite enlightening! Thanks. :-)

  That looks great for wrapping D3 or similar, @akavel. Thanks.
