Django + Wasmer Edge

This example shows how to run a standard Django 5 project on Wasmer Edge.

Demo

https://django-template.wasmer.app/

How it Works

Key files to know:

  • api/settings.py
    • Adds the sample app ('example') to INSTALLED_APPS.
    • Sets ALLOWED_HOSTS = ['127.0.0.1', '.wasmer.app'] so both local development and Wasmer Edge subdomains work.
    • Points WSGI_APPLICATION to api.wsgi.app, meaning Wasmer will import api/wsgi.py and look for app.
  • api/wsgi.py
    • Calls get_wsgi_application() and exposes it as a module-level variable named app (the entrypoint Wasmer runs).
  • example/views.py
    • Defines index(request) which renders the current time in a simple HTML page.
  • example/urls.py and api/urls.py
    • Wire the index view to the root URL (/) and include it in the project’s root URL patterns.

Because Django serves via WSGI, Wasmer Edge runs the project without extra adapters.

Running Locally

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt  # or pip install django
python manage.py migrate
python manage.py runserver

Deploying to Wasmer (Overview)

  1. Collect static files and apply migrations as part of your build (e.g., python manage.py collectstatic --no-input).
  2. Ensure api.wsgi:app is the entrypoint in your deployment configuration.
  3. Deploy to Wasmer Edge and browse to https://<your-subdomain>.wasmer.app/.
