Turning off eslint rule for a specific line – Dev

The best answers to the question “Turning off eslint rule for a specific line” in the category Dev.

QUESTION:

In order to turn off linting rule for a particular line in JSHint we use the following rule:

/* jshint ignore:start*/
$scope.someVar = ConstructorFunction();
/* jshint ignore:end */

I have been trying to locate the equivalent of the above for eslint.

ANSWER:

Update

ESlint has now been updated with a better way disable a single line, see @goofballLogic’s excellent answer.

Old answer:

You can use the following

/*eslint-disable */

//suppress all warnings between comments
alert('foo');

/*eslint-enable */

Which is slightly buried the “configuring rules” section of the docs;

To disable a warning for an entire file, you can include a comment at the top of the file e.g.

/*eslint eqeqeq:0*/

ANSWER:

To disable next line:

// eslint-disable-next-line no-use-before-define
var thing = new Thing();

Or use the single line syntax:

var thing = new Thing(); // eslint-disable-line no-use-before-define

See the eslint docs

ANSWER:

From Configuring ESLint – Disabling Rules with Inline Comments:

/* eslint-disable no-alert, no-console */


/* eslint-disable */

alert('foo');

/* eslint-enable */


/* eslint-disable no-alert, no-console */

alert('foo');
console.log('bar');

/* eslint-enable no-alert, no-console */


/* eslint-disable */

alert('foo');


/* eslint-disable no-alert */

alert('foo');


alert('foo'); // eslint-disable-line

// eslint-disable-next-line
alert('foo');


alert('foo'); // eslint-disable-line no-alert

// eslint-disable-next-line no-alert
alert('foo');


alert('foo'); // eslint-disable-line no-alert, quotes, semi

// eslint-disable-next-line no-alert, quotes, semi
alert('foo');


foo(); // eslint-disable-line example/rule-name

ANSWER:

You can also disable a specific rule/rules (rather than all) by specifying them in the enable (open) and disable (close) blocks:

/* eslint-disable no-alert, no-console */

alert('foo');
console.log('bar');

/* eslint-enable no-alert */
