ESLint not working in VS Code?
JavascriptVisual Studio-CodeEslintJavascript Problem Overview
ESLint is not working for me in VS Code. I have the plugin installed in VS Code, and ESLint itself as a developer dependency in my package.json, which I have installed as well.
I modified the following option in the VS Code User Settings:
{
"eslint.options": { "configFile": "C:/mypath" }
}
I have use the command eslint --init
to add the basic .eslintrc.json
to the main directory of my package.
Other people were able to get ESLint feedback from VS Code using the exact same package with the exact same ESLint config file.
I have received no feedback of any kind when directly breaking multiple rules that were all included in the recommended rule set that is by default inside of the .eslintrc.json
file.
What am I missing?
Edit: I have tested using ESLint via command line, and everything worked as expected, with the errors found where they should have, however, these same errors never showed up in VS Code. The issue seems to be on VS Code's side and not ESLint.
Javascript Solutions
Solution 1 - Javascript
If ESLint is running in the terminal but not inside VSCode, it is probably
because the extension is unable to detect both the local and the global
node_modules
folders.
To verify, press Ctrl+Shift+U in VSCode to open
the Output
panel after opening a JavaScript file with a known eslint
issue.
If it shows Failed to load the ESLint library for the document {documentName}.js
-or- if the Problems
tab shows an error or a warning that
refers to eslint
, then VSCode is having a problem trying to detect the path.
If yes, then set it manually by configuring the eslint.nodePath
in the VSCode
settings (settings.json
). Give it the full path (for example, like
"eslint.nodePath": "C:\\Program Files\\nodejs"
) -- using environment variables
is currently not supported.
This option has been documented at the ESLint extension page.
Solution 2 - Javascript
In my case, since I was using TypeScript with React, the fix was simply to tell ESLint to also validate these files. This needs to go in your user settings:
"eslint.validate": [ "javascript", "javascriptreact", "html", "typescriptreact" ],
Solution 3 - Javascript
configuring working directories solved it for me, since I had multiple projects with own .eslintrc
files openend in the same window.
Put this in your .vscode/settings.json
"eslint.workingDirectories": [
"./backend",
"./frontend"
],
thanks to this guy on github: https://github.com/microsoft/vscode-eslint/issues/696#issuecomment-542592372
PS: useful command to list all subdirectories containing an .eslintrc
except /node_modules:
find . .eslintrc | grep .eslintrc | grep -v node_modules
Solution 4 - Javascript
There are a few reasons that ESLint may not be giving you feedback. ESLint is going to look for your configuration file first in your project and if it can't find a .eslintrc.json there it will look for a global configuration. Personally, I only install ESLint in each project and create a configuration based off of each project.
The second reason why you aren't getting feedback is that to get the feedback you have to define your linting rules in the .eslintrc.json. If there are no rules there, or you have no plugins installed then you have to define them.

Case 1/2: First-time plugin installation? approval is necessary
Little "weird" user experience (Hard to notice) - anyway - Since V 2.1.10 -
You must change the "currently block" status bar on New/First installation.
2.1.10
changelog (08/10/2020)
ESLint plugin Version > no modal dialog is shown when the ESLint extension tries to load an > ESLint library for the first time and an approval is necessary. > Instead the ESLint status bar item changes to ESLint status icon > indicating that the execution is currently block.
Click on the status-bar
(Right-Bottom corner):
Opens this popup:
Approve ==> Allows Everywhere
-or- by commands:
ctrl + Shift + ESLint: Manage Library Execution
Read more here under "Release Notes":
https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint
Case 2/2: The plugin already installed/approve
Open the terminal Ctrl+`
Under output ESLint
dropdown, you find useful debugging data (Errors, warnings, info).
For example, missing .eslintrc-.json
throw this error:
Error: ENOENT: no such file or directory, realpath
Next, check if the plugin enabled:
By deafult there is no need to edit eslint.probe
Last, Since v 2.0.4 - eslint.validate
in "normal cases" (react, vue, typescript, js, html, md) not necessary anymore (old legacy setting)**
**Many out-of-date stackoverflow answers (even her) indicate that eslint.probe
file should be edited.
> eslint.probe
= an array for language identifiers for which the
> ESLint extension should be activated and should try to validate the
> file. If validation fails for probed languages the extension says
> silent. Defaults to [javascript
, javascriptreact
, typescript
,
> typescriptreact
, html
, vue
, markdown
].

In my case, I had not installed he ESLint extension in VSCode, which was causing issue. Did it and it started working again.
Solution 7 - Javascript
Since you are able to successfully lint via command line, the issue is most likely in the configuration of the ESLint plugin.
Assuming the extension is properly installed, check out all ESLint related config properties in both project (workspace) and user (global) defined settings.json.
There are a few things that could be misconfigured in your particular case; for me it was JavaScript disabled after working with TypeScript in another project and my global settings.json ended up looking following:
"eslint.validate": [
{ "language": "typescript", "autoFix": true }
]
From here it was a simple fix:
"eslint.validate": [
{ "language": "javascript", "autoFix": true },
{ "language": "typescript", "autoFix": true }
]
This is so common that someone wrote a straight forward blog post about ESLint not working in VS Code. I'd just add, check your global user settings.json before overriding the local workspace config.
Solution 8 - Javascript
Restarting VSCode worked for me.
Solution 9 - Javascript
If you are using a global installation of ESLint, any plugins used in your configuration must also be installed globally. Like wise for local install. if u have installed locally and properly configured locally, yet eslint isn't working, try restarting your IDE. This just happened to me with VScode.
Solution 10 - Javascript
In my case ESLint was disabled in my workspace. I had to enable it in vscode extensions settings.
Solution 11 - Javascript
In my case setting eslint validate to : "eslint.validate": [ "javascript", "javascriptreact", "html", "typescriptreact" ], did the job.
Solution 12 - Javascript
I resolved the issue by restarting the ESLint Server. You can do this by opening up the Ctrl
+ P
menu. Then you can enter > ESLint: Restart ESLint Server
.
Solution 13 - Javascript
I use Use Prettier Formatter and ESLint VS Code extension together for code linting and formating.
now install some packages using given command, if more packages required they will show with installation command as an error in the terminal for you, please install them also.
npm i eslint prettier eslint@^5.16.0 eslint-config-prettier eslint-plugin-prettier eslint-config-airbnb eslint-plugin-node eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks@^2.5.0 --save-dev
now create a new file name .prettierrc in your project home directory, using this file you can configure settings of the prettier extension, my settings are below:
{
"singleQuote": true
}
now as for the ESlint you can configure it according to your requirement, I am advising you to go Eslint website see the rules (https://eslint.org/docs/rules/)
Now create a file name .eslintrc.json in your project home directory, using that file you can configure eslint, my configurations are below:
{
"extends": ["airbnb", "prettier", "plugin:node/recommended"],
"plugins": ["prettier"],
"rules": {
"prettier/prettier": "error",
"spaced-comment": "off",
"no-console": "warn",
"consistent-return": "off",
"func-names": "off",
"object-shorthand": "off",
"no-process-exit": "off",
"no-param-reassign": "off",
"no-return-await": "off",
"no-underscore-dangle": "off",
"class-methods-use-this": "off",
"prefer-destructuring": ["error", { "object": true, "array": false }],
"no-unused-vars": ["error", { "argsIgnorePattern": "req|res|next|val" }]
}
}
Solution 14 - Javascript
I had similar problem on windows, however sometimes eslint worked (in vscode) sometimes not. Later I realized that it works fine after a while. It was related to this issue: eslint server takes ~3-5 minutes until available
Setting enviroment variable NO_UPDATE_NOTIFIER=1
solved the problem
Solution 15 - Javascript
I'm giving the response assuming that you have already defined rules in you local project root with .eslintrc and .eslintignore. After Installing VSCode Eslint Extension several configurations which need to do in settings.json for vscode
eslint.enable: true
eslint.nodePath: <directory where your extensions available>
Installing eslint local as a project dependency is the last ingredient for this to work. consider not to install eslint as global which could conflict with your local installed package.
Solution 16 - Javascript
I had a similar problem with eslint saying it was '..not validating any files yet', but nothing was reported in the VS Code problems console. However after upgrading VS Code to the latest version (1.32.1) and restarting, eslint started working.
Solution 17 - Javascript
In my case, I had to enable the ESLint "Always Show Status" setting in VSCode:
Then linting results started showing up immediately in VSCode.
Solution 18 - Javascript
If you are developing a project with eslint as an package.json dependency, make sure you run npm install
. That fixed it for me.
Solution 19 - Javascript
For me, i did accidentally disable ESLint when some prompt was shown by it.
Doing below steps fixed it for me
Shift + Command + P
and selectESLint: Disabled ESLint
- Close vscode
Shift + Command + P
and selectESLint: Show Output Channel
Solution 20 - Javascript
In my case, it wasn't working because I had added only one folder of the monorepo to the project, even though I had the package.json
and the extension configured. I worked only when I added the whole project (which contained the package.json
file) to the VS Code.
Solution 21 - Javascript
After installing the Eslint npm package and/or VS Code Extension by Dirk baeumer, Create .eslintrc.js configuration file as per your coding conventions.
Then, Enable all ESLint configurations in VSCode settings as follows:
- Pressing shortcut key Ctrl + or Command + based on your OS OR search "Settings"
- Type @ext:dbaeumer.vscode-eslint in your Search bar
- Tick mark the following checkboxes
- Eslint: Debug
- Eslint: Enable
- Eslint: Format Enable
- Eslint: Lint Task Enable
Happy Linting 邏
Solution 22 - Javascript
The .eslintrc.js file had a typo . More specifically I tried to add a rule in a wrong way . Once I removed the falsey rule everything was working fine immediately .
Solution 23 - Javascript
Go to your settings.json file, add the following and, fix the eslint.nodepath. Tailor it to your own preferences.
// PERSONAL
"editor.codeActionsOnSaveTimeout": 2000,
"editor.codeActionsOnSave": {
"source.fixAll": true
},
"editor.fontSize": 16,
"editor.formatOnSave": true,
"explorer.confirmDragAndDrop": true,
"editor.tabSize": 2,
"eslint.codeAction.showDocumentation": {
"enable": true
},
"eslint.nodePath": "C:\\{path}",
"eslint.workingDirectories": ["./backend", "./frontend"],
Solution 24 - Javascript
In my case, I had the .eslintrc.json
file inside the .vscode
folder. Once I moved it out to the root folder, ESLint started working correctly.
Solution 25 - Javascript
You can open problem
tab to check there is an ESLint permission request or not. If you see it, try to click the lightbulb and fix the issue, it works for me.
problem tab in vscode terminal window
wish you luck!
Solution 26 - Javascript
Windows user here.
Tried everything, nothing worked. Finally removing the folder with eslint in .vscode/extensions and reinstalling fixed!
> C:\Users<user>.vscode\extensions
Solution 27 - Javascript
If you are using Yarn version 2, it might be the culprit. For me, once I ran yarn set version classic
and yarn install
everything started working again.
Solution 28 - Javascript
I had the same issue. ESLint extension was enabled and .eslintrc file had some rules but VS Code did not show any autofix for my code.
The problem was in my folder structure, it was something like that
-workspace-folder
-client
-node_modules
-src
-.eslintrc.json
-package.json
-...other files
After changing folder structure to the like below example, with the delete package-lock.json and reinstallation of all deps, VS code began to show es lint errors.
-workspace-folder
-node_modules
-src
-.eslintrc.json
-package.json
-...other files
Solution 29 - Javascript
I get the same problem of eslint not working. When adding these extensions in .eslintrc.json file, it works fine for me :
"extends": [
"plugin:@angular-eslint/recommended",
"plugin:@angular-eslint/template/process-inline-templates",
"eslint:recommended",
"plugin:@typescript-eslint/recommended"
],
Solution 30 - Javascript
In my case, I followed https://eslint.org/docs/user-guide/getting-started#installation-and-usage to setup the es-lint. But after the installation it's wasn't working.
Fix: But just restarting the vs-code solved the problem for me.
Solution 31 - Javascript
In my case ESLint was properly installed and enabled and working in another workspace with identical settings.
What helped was to disable the extension in the workspace where it was not working, reload VSCode and then enable the extension back. Then it immediately started working.
Solution 32 - Javascript
For me, the latest version of eslint does not work correctly with Visual Studio code in all my packages, so I had to install an earlier global version:
npm i -g [email protected]
