Supported Frameworks and Languages

Start from a template on the Wasmer website: https://wasmer.io/templates . Wasmer includes custom detection that identifies your repository type (e.g., Next.js, Astro, Laravel, WordPress, Symfony, Django, Flask, FastAPI, MCP, and more), packages it automatically with Wasmer, and deploys it to Wasmer Edge — no Dockerfile required.

PHP

Detection: any repo containing at least one .php file is treated as PHP.
Dependencies: Composer dependencies are installed automatically (composer.json / composer.lock).
Frameworks: Laravel, Symfony, WordPress.
Notes: Typical entry points like public/index.php are supported.

Python

Detection: presence of requirements.txt or pyproject.toml.
Dependencies: installed automatically in the deployment image.
Post‑deploy tasks: framework‑specific steps can run (e.g., Django migrations).
Frameworks: Django, Flask, FastAPI, MCP, Streamlit.
Servers: Uvicorn (ASGI and WSGI), Daphne (ASGI).

Example layout:


# Python
requirements.txt  or  pyproject.toml
app.py            # Flask / FastAPI entrypoint
manage.py         # Django projects

Static Sites

Detection: index.html at the repo root or a Staticfile.
Served directly from the Edge network.

JavaScript Frameworks (auto‑detected)

Examples: Next.js, Astro.
Typical signals: framework configs (e.g., next.config.*, astro.config.*) and package scripts (build, dev). Wasmer builds and packages for Edge.

Databases (auto‑detected)

Support: MySQL (currently supported).
Behavior: If your app requires a database, Wasmer will automatically detect it and attach a MySQL database to your app.
Connection: When running on Wasmer Edge, these environment variables are prepopulated with the connection details:
- DB_HOST, DB_PORT, DB_NAME, DB_USER, DB_PASSWORD.

Quick Reference


PHP:       any *.php  → installs Composer deps
Python:    requirements.txt | pyproject.toml → installs deps, runs framework steps
Static:    index.html | Staticfile → served as static
JS:        Next.js / Astro → auto build + package
DB:        MySQL (auto‑detected) → env: DB_HOST, DB_PORT, DB_NAME, DB_USER, DB_PASSWORD

To get started, pick a template at https://wasmer.io/templates and push your code. The platform will handle dependency installation, build, packaging, and rollout to Wasmer Edge automatically.
