Micro-frontends of edX are currently using Node JS v16 that will no longer get support after September 11, 2023. We have to upgrade Node JS version to v18 before that

Approach

We have created tickets in each MFE for node upgrade ticket and all the tickets are added in Maintenance board. FED-BOM is creating PRs in each MFEs and adding these in the Maintenance boards as well. FED-BOM is following these steps to upgrade Node JS

Steps to upgrade

  • First we need to use node v18. The suggested way is to use nvm to use Node v18

  • Delete the package-lock.json file and run npm install

  • Identify and update packages according to node v18

  • Add/Update .nvmrc to use v18

  • Update CI workflow to use node version from .nvmrc

  • Update Release workflow to use node version from .nvmrc

  • Update lockfileversion-check.yml workflow to use openedx/.github/.github/workflows/lockfileversion-check-v3.yml@master

  • Update Readme according to node v18 changes

  • Run unit tests, linting and build scripts if exists.

  • Test extract (pull/push) translations

  • Start & test the project

  • Perform consumer testing if its a library to check its impacts on consumers

  • If its a library and consumers are breaking with node upgrade, it should be release as a major version so renovate doesn’t auto merge its changes in consumers.

Know issues

  • Sometimes npm create cache with node 16 and when run on node 18 it might cause some random errors(e.g: axios mock errors). To handle such issues, it is recommended to remove node_modules.

  • In some cases, we have to update semantic release version to v20 as v20 of semantic release doesn’t support node version <18
