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.

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

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 in 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*/

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 */

via @goofballMagic's link above:

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 use an inline comment: // eslint-disable-next-line rule-name.

Example

// eslint-disable-next-line no-console
console.log('eslint will ignore the no-console on this line of code');

Reference

ESLint - Disabling Rules with Inline Comments

1

The general end of line comment, // eslint-disable-line, does not need anything after it: no need to look up a code to specify what you wish ES Lint to ignore.

If you need to have any syntax ignored for any reason other than a quick debugging, you have problems: why not update your delint config?

I enjoy // eslint-disable-line to allow me to insert console for a quick inspection of a service, without my development environment holding me back because of the breach of protocol. (I generally ban console, and use a logging class - which sometimes builds upon console.)

Or for multiple ignores on the next line, string the rules using commas

// eslint-disable-next-line class-methods-use-this, no-unused-vars

To disable a single rule for the rest of the file below:

/* eslint no-undef: "off"*/
const uploadData = new FormData();

1

To disable all rules on a specific line:

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

single line comment did not work for me inside a react dumb functional component, I have used file level disabling by adding /* eslint-disable insertEslintErrorDefinitionHere */

(normally if you are using vs code and getting eslint error, you can click on the line which gives error and a bulb would show up in vs code, right click on the light bulb and choose any disable option and vs code will do it for you.)

My answer, similar to others given, but shows how you can also add a comment to yourself on the same line.

// eslint-disable-line // THIS WON"T WORK

Use -- if you also need to write a comment on that line (eg. maybe why eslint is disabled)

// eslint-disable-line -- comment to self (This DOES work)

Can be used in conjunction with specific eslint rules to ignore:

// eslint-disable-line no-console -- comment to self (This Also Works!)

You can add the files which give error to .eslintignore file in your project.Like for all the .vue files just add /*.vue
