Running Datasette on Replit#

I figured out how to run Datasette on https://replit.com/

The trick is to start a new Python project and then drop the following into the main.py file:

1
import uvicorn
2
from datasette.app import Datasette
3

4
ds = Datasette(memory=True, files=[])
5

6

7
if __name__ == "__main__":
8
    uvicorn.run(ds.app(), host="0.0.0.0", port=8000)

Replit is smart enough to automatically create a pyproject.toml file with datasette and uvicorn as dependencies. It will also notice that the application is running on port 8000 and set https://name-of-prject.your-username.repl.co to proxy to that port. Plus it will restart the server any time it recieves new traffic (and pause it in between groups of requests).

To serve a database file, download it using wget in the Replit console and add it to the files=[] argument. I ran this:

1
wget https://datasette.io/content.db

Then changed that first line to:

1
ds = Datasette(files=["content.db"])

And restarted the server.
