Ignore multiple files or folders – To turn off ESLint in the whole file, you can add /* eslint-disable */ in the first line of that file. Alternatively, you can create a file,eslintignore in the root catalog. The format of this file matches the format of,gitignore and you can add there not only files but directories too.

How do I disable workspace ESLint?

is there any way to disable just few rules rather than the whole eslint? Jun 15, 2020 at 15:06 @SirajAlam I don’t think you can do that with VS Code settings, you would have to configure your,eslintrc file to disable specific rules. eslint.org/docs/user-guide/configuring Jun 17, 2020 at 13:13 this warning is shown This setting is deprecated. Disable ESLint using the extensions viewlet. Dec 9, 2020 at 16:05 @AwaisNasir definately agree. Only melMass updated their answer stackoverflow.com/a/65268582/1906088 and it needs to be appreciated cause it’s the only one up to date for this one at the moment. Jan 28, 2021 at 7:57
The old: “eslint.enable”: false Is deprecated, now you need to use the builtin VSCode mechanism for disabling extensions:

Create,vscode folder in your project root and there create a settings.json then add the following config: Maybe after this setting you should consider adding the,vscode/settings.json line to your,gitignore file too, but it is based on your dev team’s preference. webpreneur webpreneur 746 9 silver badges 15 bronze badges 2

Uncheck the EsLint:Enable 
answered Oct 24, 2018 at 11:45 1-) npm install -g eslint 2-) Open up settings.json and add the property: “eslint.enable”: false answered Oct 24, 2018 at 9:12 
In VSCode, go to File >> preferences >> settings Type ‘eslint quiet’ in the search bar and click the check box for quiet mode. In quiet mode, eslint would ignore basic errors. This should work for many VSCode users as at March 4, 2022. You’re welcome! answered Mar 4 at 17:33 Emeka Orji Emeka Orji 159 3 silver badges 9 bronze badges 1
To be more precise, the Quiet setting ignores warnings in the VSC UI. Oct 8 at 19:14
Please open settings.json file and edit the configuration as below: “eslint.enable”: false Hope this helps. answered Sep 21 at 16:23

This does not disable ESLint, it just applies automatic fixes which so that the syntax warnings/errors are resolved. OP only wanted to disable the integration, or markers that were set by ESLint extension. Oct 8 at 19:18
Is ESLint mandatory?
No offense bro, but to me, it seems ESLint isn’t a big deal. My production code has been running for 2 years without linting at all. Why should I use one now? First, I’d like to say that it’s true. You can work with JavaScript without linting. In fact you can work with any programming language without linting at all. Every wrong syntax will trigger an error, and you’ll have to fix your code before putting it live. From my experience however, linters most useful function is that it makes the app look like it was written by one person, Every developer has their own style, and using ESLint means you have a written agreement about how your JavaScript code base should look like. Okay, I understand that one. But code style alone isn’t enough to convince me. Have you ever made a commit where you forgot to cleanup console.log() ? ESLint can catch those code and returns error. Hey, now that you mention it, sometimes I do that. Yeah, sometimes developers are exhausted from looking at their editor all day long. Small mistakes, but still need to be fixed nonetheless. Also, sometimes we forgot to delete unused import statements, At one time I imported a React component that I needed for development, but by the time I’m done with the task, I have removed the component from use. The import statement was left in the file, which should’ve been deleted. Whoops. Sometimes I did that too. Whoopsie. Yes, ESLint will make you see those pesky unused variables or imports. Another useful thing about ESLint is that it can help you with stuff that’s hard to catch by running or looking at the code. Consider this example. Can you guess what’s wrong with the code? for ( i = 10 ; i >= 5 ; i ++ ) Enter fullscreen mode Exit fullscreen mode Hmm. What’s wrong with it? Kinda hard to see, huh? Well, the increment value is moving in the wrong direction and causing infinite loop. Ah my bad! Rather than thinking about what’s wrong with the code, you can have ESLint tell you that the loop will never end. It can save some seconds. LOL Let’s see another example here: if ( username = ” Douglas ” ) Enter fullscreen mode Exit fullscreen mode That’s assignment operator there, not comparison. Yeah, and when you run the code JavaScript will just return true instead of yelling at you. Linters will disallow assignment operator in conditional statements where comparison operator is expected. Oh. that’s neat. still I’ve seen its documentation, seems I need to configure lots of stuff before I used it. Well, you do configure Gulp or Webpack for your project all the time, don’t you? ESLint configuration isn’t that hard to get. If you’re really that lazy though, you can just use its shareable config which you can use freely. Like boilerplate rules, huh? Yes, but don’t just set it and then forget! You have to see if the rule make sense for the project. As an example, there is ES Style Guide by Google here. Make sure you see its documentation first. Sigh. is there any way I can just set and forget? Another configuration to maintain is burdensome. Well, there is an initiative to make a universal rule of high quality JavaScript code that you can just install and run without configuring anything at all. It’s called Standard, The rules laid out in Standard are fixed and contributors debate on the issue section of the repo for the rules. Awesome! I’m gonna try that! If you decided to use it, there’s also text editor plugins you can use. Alright. One less configuration to think about! You know what’s funny? What? Somehow I think many developers do agree with you on ESLint configuration being a burden. Standard managed to snag the first place in Github clean code linters collection, Well, not all developers are the same. Most definitely don’t love the idea of having to configure everything. Except you, maybe. Maybe. 🤓 Anyway, don’t forget to add a git hook so that the linter is always run before a commit.

Does ESLint run automatically?
Step 4 – Adding Code Actions on Save – Trying to manually run ESLint: Fix all auto-fixable Problems periodically is not very reliable. However, having lint rules run every time you save your work can be more reliable. You can set up ESLint to run auto-fix every time you press CTRL+S (or COMMAND+S ). For ESLint to work correctly on file same, you must change the Visual Studio Code preferences. Go to File > Preferences > Settings (or Code > Preferences > Settings ). For this tutorial, we will modify the – it is also possible to apply these settings for all projects. Click Workspace and search for Code Actions On Save : Editor: Code Actions On Save Code action kinds to be run on save. Edit in settings.json Then click settings.json,,vscode/settings.json In settings.json paste the following code:,vscode/settings.json, “eslint.validate” : } Now, undo the fixes you made to the JavaScript file you created earlier. Then save the file. The auto-fixable problems will be automatically addressed.

How do I disable TypeScript in a file?
Disable type checking for JavaScript files in TypeScript Borislav Hadzhiev Last updated: Mar 12, 2022 Use the // @ts-nocheck comment to disable all type checking in a TypeScript file. If you need to disable all type checking for JavaScript files, set the checkJs option to false in your tsconfig.json file. When the option is disabled, errors are not reported in JS files.
Index.ts Copied! // 👇️ ts-nocheck disables type checking for entire file // eslint-disable-next-line @typescript-eslint/ban-ts-comment // @ts-nocheck // 👇️ ts-ignore ignores any ts errors on the next line // eslint-disable-next-line @typescript-eslint/ban-ts-comment // @ts-ignore function multiply ( a, b ) The comment disables type checking for an entire file.
If you’re using a linter, you might have to disable the ban-ts-comment rule on the previous line. If you need to disable all type checking for JavaScript files, you have to set the option to false in your tsconfig.json file. tsconfig.json Copied! } The option allows you to import JavaScript files in your TypeScript project.
- By default you are only allowed to import files with,ts and,tsx extensions, but when allowJs is enabled, you can also import,js and,jsx files in your TypeScript files.
- When the checkJs option is enabled, errors are reported in all JavaScript files in your project.
- Setting checkJs to false disables all error reporting for JavaScript files in your TypeScript project, but you are still able to import and use your Javascript files because the allowJs option is set to true,
If you only want to disable type checking for a single line, you can use the // @ts-ignore comment. index.ts Copied! // eslint-disable-next-line @typescript-eslint/ban-ts-comment // @ts-ignore function multiply ( a, b ) The // @ts-ignore comment disables all type checking errors on the next line.

How do I tell ESLint to ignore a folder?
The,eslintignore File – You can tell ESLint to ignore specific files and directories by creating a,eslintignore file in your project’s root directory. The,eslintignore file is a plain text file where each line is a glob pattern indicating which paths should be omitted from linting.
- For example, the following omits all JavaScript files: **/*.js When ESLint is run, it looks in the current working directory to find a,eslintignore file before determining which files to lint.
- If this file is found, then those preferences are applied when traversing directories.
- Only one,eslintignore file can be used at a time, so,eslintignore files other than the one in the current working directory are not used.
Globs are matched using, so a number of features are available:
Lines beginning with # are treated as comments and do not affect the ignore patterns. Paths are relative to the current working directory. This is also true of paths passed in via the -ignore-pattern, Lines preceded by ! are negated patterns that re-include a pattern that was ignored by an earlier pattern. Ignore patterns behave according to the,gitignore,
Of particular note is that like,gitignore files, all paths used as patterns for both,eslintignore and -ignore-pattern must use forward slashes as their path separators. # Valid /root/src/*.js # Invalid \root\src\*.js Please see ‘s specification for further examples of valid syntax.
node_modules/ is ignored. dot-files (except for,eslintrc.* ) as well as dot-folders and their contents are ignored.
There are also some exceptions to these rules:
If the path to lint is a glob pattern or directory path and contains a dot-folder, all dot-files and dot-folders are linted. This includes dot-files and dot-folders that are buried deeper in the directory structure. For example, eslint,config/ would lint all dot-folders and dot-files in the,config directory, including immediate children as well as children that are deeper in the directory structure. If the path to lint is a specific file path and the -no-ignore flag has been passed, ESLint would lint the file regardless of the implicit ignore rules. For example, eslint,config/my-config-file.js -no-ignore would cause my-config-file.js to be linted. It should be noted that the same command without the -no-ignore line would not lint the my-config-file.js file. Allowlist and denylist rules specified via -ignore-pattern or,eslintignore are prioritized above implicit ignore rules. For example, in this scenario,,build/test.js is the desired file to allowlist. Because all dot-folders and their children are ignored by default,,build must first be allowlisted so that eslint becomes aware of its children. Then,,build/test.js must be explicitly allowlisted, while the rest of the content is denylisted. This is done with the following,eslintignore file: # Allowlist ‘test.js’ in the ‘.build’ folder # But do not allow anything else in the ‘.build’ folder to be linted !.build,build/* !.build/test.js The following -ignore-pattern is also equivalent: eslint -ignore-pattern ‘!.build’ -ignore-pattern ‘.build/*’ -ignore-pattern ‘!.build/test.js’ parent-folder/

How do I get rid of unused imports in ESLint?
Automatically remove unused imports – To automatically remove unused imports, we will need to add the eslint-plugin-unused-imports plugin. Install it using npm: npm install eslint-plugin-unused-imports -save-dev Then add it to your configuration file; here with the recommended rules from the author: ] } } Now, when you run ESLint, you should see error lines saying error ‘ ‘ is defined but never used unused-imports/no-unused-imports for the files where you have unused imports.

Why is ESLint needed?
Table of Contents – ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code, with the goal of making code more consistent and avoiding bugs. In many ways, it is similar to JSLint and JSHint with a few exceptions:
ESLint uses Espree for JavaScript parsing. ESLint uses an AST to evaluate patterns in code. ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.
Is linting necessary?
Why Is Linting Important? – Linting is important to reduce errors and improve the overall quality of your code. Using lint tools can help you accelerate development and reduce costs by finding errors earlier.

Why is ESLint taking so long?
Review the ESLint Config – TIMING=1 revealed that the prettier/prettier rule was taking up ~70% of the lint runtime for our project! $ TIMING = 1 eslint,/ Rule | Time ( ms ) | Relative :- | -: | -: prettier/prettier | 451.628 | 69.2 % import/no-unresolved | 26.703 | 4.1 % import/no-extraneous-dependencies | 22.003 | 3.4 % no-unused-vars | 9.794 | 1.5 % no-redeclare | 8.697 | 1.3 % react/jsx-no-bind | 7.798 | 1.2 % import/no-named-as-default-member | 6.610 | 1.0 % react/no-deprecated | 5.764 | 0.9 % react/destructuring-assignment | 5.180 | 0.8 % react/void-dom-elements-no-children | 4.900 | 0.8 % I had originally set up our ESLint config with eslint-plugin-prettier to run Prettier as an ESLint rule through this config:,eslintrc.js The alternative would be to run Prettier through the prettier-vscode Visual Studio Code extension.
