Devcontainer WASM-Python

Simple devcontainer for Python development.

Note that Python + WASM is a little different for now, since the interperter (python.wasm) runs a standard .py python script. There is no really great way to package up a script and python.wasm into a single bundle for now, so that is sadly an exercise for the reader.

Usage

Github Codespaces

Just click the button:

Visual Studio Code

Note this assumes that you have the VS code support for remote containers and docker installed on your machine.

git clone https://github.com/dev-wasm/dev-wasm-python
cd dev-wasm-python
code ./

Visual studio should prompt you to see if you want to relaunch the workspace in a container, you do.

Running

Simple example

./python3-wasm main.py

Web serving with WAGI

There is a simple example of web serving via WebAssembly + CGI (WAGI) in the webserver directory. It uses the lighttpd web server and mod_cgi. See the webserver/lighttpd.conf file for more details.

lighttpd -D -f webserver/lighttpd.conf

Once the server is running, VS Code or Codespaces should prompt you to connect to the open port.

It is important to note that the current configuration allows filesystem access to a variety of filepaths for both read and write. This should be considered for test use only, we need to lock down to read-only access for production.

TODO

• Figure out how to get PIP working
• Figure out how to package Python + script as a single .wasm file
