Ensuring Version Consistency Across All Environments
Blog post from RWX
Engineering teams should pin identical major, minor, and patch versions of tools and runtimes across development, staging, and production to avoid subtle compatibility failures. RWX encountered such an issue when code relying on default arguments in Node.js 20.12.2 ran on 20.11.1, where those defaults were unavailable; acceptance tests caught the resulting error in staging, but version checks could have prevented it earlier. The recommended approach is to maintain a single version source of truth, such as an asdf `.tool-versions` file, and enforce consistency through CI. RWX extracts Node.js, Go, and pnpm versions from this file, supplies them to installation tasks, and uses checks against provisioning scripts, package metadata, and dependency-installation scripts to ensure every reference matches. File filters allow the validation task to run efficiently by using cached results when relevant version files have not changed.
