@ionic/v4-migration-tslint

An effort to warn about and automatically fix syntax changes listed in BREAKING.md using tslint, codelyzer, and the Angular compiler.

We are looking for contributors to help build these rules out! See CONTRIBUTING.md to help out. 💖

   📝 Hints:

   • Run tslint with -t verbose to output the rule names of lint errors which correspond to the table of rules below.
   • Run tslint with --fix to attempt automatic fixes (note: not all rules have fixes, and be sure to save a backup in version control before running with --fix)

Rules
