Your Angular tech debt can now fix itself — ahc fix

bash

$ ahc fix . --dry-run



  Would apply 12 fixes:

  ~ src/app/user-list.component.ts:8   Added OnPush to "UserListComponent"

  ~ src/app/cart.service.ts:45         Removed console.log('debug')



$ ahc fix .

  ✔ 12 fixes applied. Review with git diff, then re-run ahc scan.

What it fixes today — deliberately conservative:



Missing OnPush — inserts changeDetection: ChangeDetectionStrategy.OnPush plus the import. Real AST transform (ts-morph), not regex.

console.log — removed. console.warn/console.error stay (usually intentional), and console.log used as an expression value is never touched.

--dry-run first, always. And the CLI reminds you: OnPush changes

rendering behavior — review the diff before committing.



Rules that know your Angular version

The scanner reads @angular/core from your package.json and gates

rules accordingly:





Angular 14 detected — Signals rules skipped (requires Angular 16+)

No noise about input() migration on Angular 14. Rules light up as

your version unlocks them.



How far are you from modern Angular?



$ ahc migrate-check .



  Modernization readiness — Angular 18

  ✔ Standalone components      15/15

  ✔ Signal inputs              3/3

  ✔ Built-in control flow      11/11

  • OnPush change detection    13/15  → 2 components on default CD

Break the build when quality drops

Try it

No install needed:





npx @angular-health-check/cli scan .

# or

pnpm dlx @angular-health-check/cli scan .

What should ahc fix handle next? trackBy? @Input() → input()

migration? The next fixer ships based on the comments.
