CLI 4.6.1 PATCHES SOURCE MAPS, REVERTS TYPESCRIPT BUNDLING BREAKAGE

By RepoJournal · Filed · About Shopify

Shopify CLI shipped a hotfix for UI extension source maps, but immediately rolled back a production-breaking change that removed TypeScript from the bundle.

Shopify CLI 4.6.1 went live with a cherry-picked fix to serve UI extension source maps during development [1]. The fix shipped cleanly via the stable/4.6 branch [2], and the team followed standard release hygiene by removing the changeset from main to prevent duplicate changelog entries in the upcoming 4.7.0 release [3]. However, an earlier commit to remove TypeScript from the production CLI bundle [4] broke the app dev command entirely, leaving developers unable to run shopify app dev. The revert is already staged [4] and addresses the immediate blockers. The team executed 4 commits and 2 PRs across the cycle, keeping the hotfix cycle tight.
