The process of hosting a Robyn app on various cloud providers.

Railway

We will be deploying the app on Railway.

A GitHub account is needed as a mandatory prerequisite.

We will deploy a sample "Hello World," demonstrating a simple GET route and serving an HTML file.

Directory structure:

app folder/
  main.py
  requirements.txt
  index.html

Note - Railway looks for a main.py as an entry point instead of app.py. The build process will fail if there is no main.py file.

from robyn import Robyn, serve_html


app = Robyn(__file__)


@app.get("/hello")
async def h(request):
    print(request)
    return "Hello, world!"


@app.get("/")
async def get_page(request):
    return serve_html("./index.html")


if __name__ == "__main__":
    app.start(url="0.0.0.0", port=PORT)

<h1> Hello World, this is Robyn framework! <h1>
