Robyn - Robyn works on windows! 🥳

Published by sansyrox about 2 years ago

This release removes multiprocessing from windows. This was a hard decision to take but since TCP sockets are not serialisable on non Unix machines, it only made sense.

Since slow Robyn is better than a defunkt Robyn :)

What's Changed

New Contributors

Full Changelog: https://github.com/sansyrox/robyn/compare/v0.10.0...v0.11.0

You can make a request to http://localhost:5000/query?a=b and can access the params in the following way:

@app.get("/query")
async def query_get(request):

    return jsonify(query_data)

The hot reloading server is now fixed and works on Linux and OSX(i.e. on all important operating systems). Windows support for dev server is still WIP.

Special thanks to @patchgamestudio for their contribution with the query params 🥳
