Turning off eslint rule for a specific file

问题

Is it possible to turn off the eslint rule for the whole file? Something such as:

// eslint-disable-file no-use-before-define 

(Analogous to eslint-disable-line.) It happens to me quite often, that in a certain file, I'm breaking a specific rule on many places which is considered OK for that file, but I don't want to disable the rule for the whole project nor do I want to disable other rules for that specific file.

回答1:

You can turn off/change a particular rule for a file by putting the configurations at the top of the file.

/* eslint no-use-before-define: 0 */  // --> OFF

or

/* eslint no-use-before-define: 2 */  // --> ON

More info: http://eslint.org/docs/user-guide/configuring.html#configuring-rules

回答2:

Just place /* eslint-disable */ at the top of the file

You can tell ESLint to ignore specific files and directories by creating an .eslintignore file in your project’s root directory:

.eslintignore

build/*.js
config/*.js
bower_components/foo/*.js

The ignore patterns behave according to the .gitignore specification. (Don't forget to restart your editor.)

You can also disable/enable a rule like this:

/* eslint-disable no-use-before-define */
... code that violates rule ...
/* eslint-enable no-use-before-define */

Similar to eslint-disable-line as mentioned in the question. It might be a better method if you don't want to have to restore a complicated rule configuration when re-enabling it.

回答5:

To temporarily disable rule warnings in your file, use block comments in the following format:

/* eslint-disable */

This will disable ESLint until the

/* eslint-enable */

comment is reached.

Accepted answer didn't work for me (maybe a different version of eslint...? I'm using eslint v3.19.0), but did find a solution with the following...

Place the following on the top of your file

/* eslint-disable no-use-before-define */

This will disable the rule for the entire file

It's better to add "overrides" in your .eslintrc.js config file. For example if you wont to disable camelcase rule for all js files ending on Actions add this code after rules scope in .eslintrc.js.

"rules": {    
...........    
},
"overrides": [
 {
  "files": ["*Actions.js"],
     "rules": {
        "camelcase": "off"   
     }
 }
]

Based on the number of rules you want to ignore (All, or Some), and the scope of disabling it (Line(s), File(s), Everywhere), we have 2 × 3 = 6 cases.

---

1) Disabling "All rules"

Case 1.1: You want to disable "All Rules" for "One or more Lines"

Put /* eslint-disable-line */ at the end of the line(s), or /* eslint-disable-next-line */ right before the line.

Case 1.2: You want to disable "All Rules" for "One File"

Put the comment of /* eslint-disable */ at the top of the file.

Case 1.3: You want to disable "All rules" for "Some Files"

There are 3 ways you can do this:

1. You can go with 1.2 and add /* eslint-disable */ on top of the files, one by one.
2. You can put the file name(s) in .eslintignore. This works well especially if you have a path that you want to be ignored. (e.g. apidoc/**)
3. Alternatively, if you don't want to have a separate .eslintignore file, you can add "eslintIgnore": ["file1.js", "file2.js"] in package.json as instructed here.

---

2) Disabling "Some Rules"

Case 2.1: You want to disable "Some Rules" for "One or more Lines"

You can put /* eslint-disable-line quotes */ (replace quotes with your rules) at the end of the line(s), or /* eslint-disable-next-line no-alert, quotes, semi */ before the line.

Case 2.2: You want to disable "Some Rules" for "One File"

Put the /* eslint-disable no-use-before-define */ comment at the top of the file. More examples here.

Case 2.3: You want to disable "Some Rules" for "Some files"

This is less straight-forward. You should put them in "excludedFiles" object of "overrides" section of your .eslintrc as instructed here.

回答9:

/*eslint-disable */

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

/*eslint-enable */

it worked for me

回答10:

You can just put this for example at the top of the file:

/* eslint-disable no-console */

回答11:

You can turn off specific rule for a file by using /*eslint [<rule: "off"], >]*/

/* eslint no-console: "off", no-mixed-operators: "off" */

Version: eslint@4.3.0
