Web apps

Open Publish › Web. Its card, Create web app, builds the app as a website: static files that run your Python app in the visitor's browser, with no server of your own needed to run it.

When the run finishes, Download the .zip. Update builds the app as it is now. The web settings (base URL, routing, the installed app's colors, …) are on the Settings tab.

Host the app

The .zip holds a folder of static files with index.html at the top. Any web server or static host can serve it:

1. Unzip the download.
2. Upload the folder's contents to your host: for example GitHub Pages, Netlify, Cloudflare Pages, an S3 bucket, or your own nginx or Apache.
3. Open the site's address. It has to be served over http:// or https://: opening index.html from your disk doesn't work.

To try it on your computer first, serve the folder locally, e.g. python -m http.server --directory <folder> and open http://localhost:8000.

Hosting in a subfolder

If the app isn't at the root of its site (e.g. https://example.com/my-app/), set Base URL to that path (/my-app/) in Publish › Web › Settings and Update the app.

Page addresses

With Route URL strategy set to path (the default), the app's pages have clean addresses like /settings. The host then has to send every address to index.html: on most static hosts that's a "single-page app" or "fallback to index.html" option. If your host can't do that, set Route URL strategy to hash: addresses become /#/settings and need nothing from the host.

Questions

Is it the same as the preview?

Yes: both run your app in the browser with Pyodide, so the packages that work in the preview work here too.

Can Studio host it for me?

Not yet.
