Summary

Because Node.js patch and minor releases can introduce compatibility issues such as changed function signatures or character-encoding behavior, the authors aligned their language server and VS Code extension testing with the exact Node version used by VS Code. They identified VS Code’s `.nvmrc` file as the primary source for that version and chose to support the Node release used by the latest VS Code release rather than test older versions. To keep the project synchronized as VS Code updates, they created a scheduled RWX cron workflow that retrieves VS Code’s latest release tag, fetches its `.nvmrc`, clones the language server repository, detects the repository’s configured Node version using `rwx/tool-versions`, and fails when the two versions differ. Cron failures are sent to Slack, providing a prompt to update the project’s Node version when VS Code changes its runtime.
