PHOENIX DITCHES BABEL FOR JEST, MODERNIZES BUILD CHAIN
By RepoJournal · Filed · About Elixir & Phoenix
Phoenix removes a build dependency that's been dead weight for years, cutting complexity while the CI pipeline gets its first major upgrades in months.
The framework dropped Babel entirely in favor of Node's native `--experimental-vm-modules` flag [1], simplifying the test infrastructure without sacrificing functionality. This is the kind of cleanup that compounds. Fewer dependencies mean fewer security surface areas and faster test runs. Meanwhile, ESLint jumped from 10.4.1 to 10.6.0 [2], bringing new rule capabilities that'll catch more bugs before they leave local machines. The CI pipeline is getting real attention too: actions/checkout jumped a full major version to 7.0.0 [5], tightening fork PR security with new protections against pull_request_target attacks. Both actions/cache [3] and git-auto-commit-action [4] shipped updates handling edge cases that affect large repositories. These aren't flashy changes, but they're the kind that make production deployments feel snappier and CI logs less cluttered.
