Run Streamlit on Codespaces

Fork this repo, add your Streamlit app to it, and run it on GitHub Codespaces. 🎈

How it works

• .devcontainer/devcontainer.json creates a container with Python 3.10, installs your app dependencies from requirements.txt, and launches streamlit hello.

  • Edit the postAttachCommand to launch your app instead of Streamlit Hello. E.g. if your script is app.py:

    "postAttachCommand": "streamlit run app.py",

• It uses forwardPorts to make port 8501 inside the container available locally.

• Additionally, it sets the following configuration options in .streamlit/config.toml so that the app can be run on Codespaces without the addition of command line arguments:

  [server]
  enableCORS = false
  enableXsrfProtection = false

Example usage

Fork this repo, open it on GitHub Codespaces, wait for the container to load, and click the "Open in browser" button in the bottom right corner when it appears to open the Hello app:

If it weren't for the .streamlit/config.toml file, you would have had to run the following command:

streamlit hello --server.enableCORS false --server.enableXsrfProtection false
