How I can get a warning instead of an error while using ESLint?
I use ESLint 6.7.2 version with a plugin for babel and react.
This is my actual .eslintrc.json:
{
"env": {
"browser": true,
"es6": true
},
"extends": [
"eslint:recommended",
"plugin:react/recommended"
],
"globals": {
"Atomics": "readonly",
"SharedArrayBuffer": "readonly"
},
"parserOptions": {
"ecmaFeatures": {
"jsx": true
},
"ecmaVersion": 2018,
"sourceType": "module"
},
"plugins": [
"react"
],
"rules": {
},
"settings": {
"react" : {
"version": "16.7.0"
}
},
"parser": "babel-eslint"
}

To apply the ESLint no-unused-vars rule to a block of JavaScript code, we can wrap the code block that we want to apply the rule to with /* eslint-disable no-unused-vars */ and /* eslint-enable no-unused-vars */ respectively. to wrap the code that we want the rule to apply with the comments.
To automatically remove unused imports, we will need to add the eslint-plugin-unused-imports plugin. Now, when you run ESLint, you should see error lines saying error '<imported-var>' is defined but never used unused-imports/no-unused-imports for the files where you have unused imports.
If you want to disable an ESLint rule in a file or on a specific line, you can add a comment. On a single line: const message = 'foo'; console. log(message); // eslint-disable-line no-console // eslint-disable-next-line no-console console.
I've found the answer:
It enough to add a rule for no-unused-vars:
"rules": {
"no-unused-vars": "warn"
},
Also, restart the server.
