How to update the version of Node.JS / Rust / Python

We manage asdf for our tool chain. Here you can also update the used programming language. Example with Node.JS:

# List all versions of Node.JS
asdf list all nodejs

# Install version X
asdf install nodejs X

In case the repository has a .tool-versions file make sure that you change it accordingly (e.g. via asdf local nodejs X). After installing the new version make sure that you make the appropriate changes in the repository:

• Update GitHub actions (for example https://github.com/serlo/cloudflare-worker/blob/47fc44af9841fb67c5c42696aa30fd74e0865c7a/.github/workflows/js.yml#L11 need to have the right version)
• Update Dockerfile for all created docker files (example https://github.com/serlo/api.serlo.org/blob/56aff08b8c5d3d66602c53190d47ac1544d76b2b/packages/server/docker/server/Dockerfile#L1)
• For Node.JS: Update engines in package.json (see https://github.com/serlo/cloudflare-worker/blob/47fc44af9841fb67c5c42696aa30fd74e0865c7a/package.json#L83-L85)
• Make sure everything is still working (tests, lints, build of docker images, ...)
