Description

qwik migrate-v2 has only been developed and published on the v1 branch, where it ships inside @builder.io/qwik. This PR moves it to main so it ships with @qwik.dev/core. That way a fix to the migration doesn't need a v1 release, and the migration always targets the v2 version it ships with.

Related PRs:

• Companion v1 PR (makes v1's qwik migrate-v2 run this one and deletes the v1 copy): feat(cli): run migrate-v2 from @qwik.dev/core #9179. Merge and release this one first.
• The docs update (npx @qwik.dev/core@latest migrate-v2) is in the draft docs: run migrate-v2 from @qwik.dev/core@latest #9184. It should merge only after this PR is released, because docs deploy right after CI passes on main, and until then @latest still has the old migration, which fails on v1 apps pinned to Vite 7.

Commits:

1. build(cli): bundle semver and ignore, load ts-morph from the project. The v1 code imports these at the top of the file. In main's ESM cli.mjs, a top-level import of an external package would come back as chore: update pnpm-lock.yaml and package.json to include ts-morph and… #8507: every qwik command crashes when those packages are missing. semver and ignore are small, so they are now bundled. ts-morph goes through a lazy createRequire(process.cwd()), which only runs when the migration starts. This is also what lets npx @qwik.dev/core@latest migrate-v2 work: the CLI then lives in the npx cache, and it has to find the ts-morph that the migration installs into the user's project.

2. feat(cli): port the v1 migrate-v2 command. packages/qwik/src/cli/migrate-v2 is copied from origin/v1, with two small changes:

   • Two import-name lookups are narrowed to identifiers, because main's ts-morph 27 also types import specifier names as string literals.
   • visitNotIgnoredFiles now returns /-separated paths on every OS. On Windows it returned \ paths, so /routes/ and path-marker checks never matched: error-boundary renames and some warnings and next steps were silently skipped. v1 CI only ran the unit tests on Linux, so it never caught this. Main's Windows unit-test job did.

   Main's older edits to this folder are superseded: the lazy imports are now handled by the build change, and v1 deliberately reverted the jsxs/jsx-runtime rewrite in db9934f. run-migration.starters.unit.ts is left out because it copies the repo's starters, and main's starters are already v2. The qwik-local/loop-style lint rule is skipped for this folder. It is a runtime perf rule, and skipping it keeps the code close to v1, which makes the port easy to check.

Verification:

• pnpm vitest run packages/qwik/src/cli: 152 tests passed. CI's Linux and Windows unit-test jobs pass.
• pnpm build.core, which includes tsc -p packages/qwik/tsconfig.json, passes with no generated-file changes. pnpm eslint packages/qwik/src/cli, prettier and pnpm tsc.check are clean.
• Importing cli.mjs from a directory with no node_modules failed with "Cannot find package 'ignore'" before commit 1 and works after it.
• End to end with the published preview: npx https://pkg.pr.new/QwikDev/qwik/@qwik.dev/core@9178 migrate-v2 on a v1 base + playground starter (Vite ^7.3.7) installed ts-morph 23 into the project, migrated, removed ts-morph, bumped Vite to ^8.0.0 and installed @qwik.dev/core. No @builder.io references were left in the code or config, and vite build passes on the migrated app.
