TSLint Warnings instead Errors in Webstorm

That TSLint rules in Webstorm are displayed as error messages is something that drives me nuts. Today I discovered that one can change that behaviour in Webstorm:

  • 'Preferences' -> 'Editor' -> 'Inspections'
  • Select linter ('TypeScript'->'TSLint', or just use the search box with tslint
  • Change Severity to a desired level like 'Warning' or 'Weak Warning'
