If you haven't tried the autofix options for eslint and rubocop, you're seriously missing out!
- Be SURE you have a clean git status, as you'll want to review what the autofix does to your code!
- Rubocop: Be sure to be in the right directory where you have Ruby files, probably the top level of your Rails project.
rubocop -a
- eslint:: Be sure to be in the right directory where you have JS files.
eslint --fix .
or
npm run lint -- --fix
Autofixing is a HUGE time saver!
Rules are configured with a 0, 1 or 2. Setting a rule to 0 is turning it off, setting it to 1 triggers a warning if that rule is violated, and setting it to 2 triggers an error.
Rules can also take a few additional options. In this case, the rule can be set to an array, the first item of which is the 0/1/2 flag and the rest are options.
See file .eslintrc for examples of configuration
Rules can also be specified in the code file to be linted, as JavaScript comments. This can be useful when the rule is a one-off or is a override to a project-wide rule.
For example, if your file assumes a few globals and you have the no-undef rule set in the .eslintrc file, you might want to relax the rule in the current file.
/* global $, window, angular */
// rest of code
It's also useful to disable ESLint for particular lines or blocks of lines.
console.log('console.log not allowed'); // eslint-disable-line
alert('alert not allowed'); // eslint-disable-line no-alert
/* eslint-disable no-console, no-alert */
console.log('more console.log');
alert('more alert');
/* eslint-enable no-console, no-alert */
You can disable all rules for a line or block, or only specific rules, as shown above.
