Auto-fixing

The extension supports automatic fixing of warnings to the extent that it is supported by eslint. For warnings which support an auto-fix. You can apply the quick fix by either:

  • Set eslint.autoFixOnSave to true and save your file (recommended).
  • Trigger <Plug>(coc-codeaction) with mapped keys, and select a fix action in the input list.
  • Run command :CocCommand eslint.executeAutofix.
  • Trigger command eslint.executeAutofix from :CocCommand.
