how to make .eslintrc accept single quotes - javascript

I am facing this error when I 'npm start' my project:
I already know the problem is in the .eslintrc file so I added this:
"rules": {
"quotes": [2, "single"],
}
and it's not working and it's the only solution I know
Update:
I tried deleting eslintConfig from package.json and it didn't work
and also "quotes": ["error", "single"] didn't work

You can try to turn the rule off by passing 0 in the .eslintrc config file:
{
"rules": {
"quotes": [0, "single"]
}
}

Based on the heading the solution is just to add a rule to allow single quotes. Refer below config, checkout rules object:
module.exports = {
env: {
browser: true,
es2020: true,
},
extends: ["eslint:recommended", "plugin:#typescript-eslint/recommended"],
parser: "#typescript-eslint/parser",
parserOptions: {
ecmaVersion: 11,
sourceType: "module",
},
plugins: ["#typescript-eslint", "prettier"],
rules: {
"prettier/prettier": [
1,
{
trailingComma: "es5",
//to enable single quotes
singleQuote: true,
semi: true,
},
],
...require("eslint-config-prettier").rules,
...require("eslint-config-prettier/#typescript-eslint").rules,
},
};
Try this out. If it doesn't work then share a bit more about the problem. May be write a small code try to replicate the issue and then share it here.
I hope this will help you out.
Cheers :)

Run eslint with the —fix flag and the problem will go away

I think you want to disable "quote" and "prettier/prettier" rules.
Please you can pass 0 to disable a rule.
{
"rules": {
"quotes": 0,
"prettier/prettier": 0
}
}

Does somebody know a workaround for this problem with eslint

I am using lint staged and husky to verify the commits, however since today it shows me the following error in the precommit logs.
ESLint: 8.30.0
Error: .eslintrc.cjs:
Configuration for rule "indent" is invalid:
Value {"allowIndentationTabs":true} should be equal to one of the allowed values.
Value {"allowIndentationTabs":true} should be integer.
Value {"allowIndentationTabs":true} should match exactly one schema in oneOf.
This is my config in the .eslintrc.cjs file
module.exports = {
env: {
browser: true,
es2021: true
},
extends: [
'plugin:react/recommended',
'standard'
],
overrides: [
],
parserOptions: {
ecmaVersion: 'latest',
sourceType: 'module'
},
plugins: [
'react'
],
rules: {
indent: ['error', { allowIndentationTabs: true }]
}
}
I have been trying different solutions but in the end they all give the same error
indent rule doesn't have that option
no-tabs has it but I guess it's not what you wanted

Align JavaScript imports "from" Statement to be Vertically Aligned

I would like the end result of my imports to be like this, via a tool that can automatically format my code onSave:
import { Stack, StackProps, Duration, Resource } from "aws-cdk-lib";
import { LambdaStack } from "./lambda-Stack";
import { Construct } from "constructs";
How can I align all of the "from" statements vertically in VS Code? I've looked at both prettier and eslint.
Prettier doesn't care what you want. :-) It's an opinionated tool useful for applying consistency to code within teams (and for avoiding arguments about different formatting styles [although you just get arguments about whether to use Prettier instead]).
If you don't want Prettier's formatting, don't use Prettier. There are other code formatters, some of which offer more control than Prettier does.
You could tell Prettier to ignore each of those import statements:
// prettier-ignore
import { Stack, StackProps, Duration, Resource } from "aws-cdk-lib";
// prettier-ignore
import { LambdaStack } from "./lambda-Stack";
// prettier-ignore
import { Construct } from "constructs";
or
/* prettier-ignore*/ import { Stack, StackProps, Duration, Resource } from "aws-cdk-lib";
/* prettier-ignore*/ import { LambdaStack } from "./lambda-Stack";
/* prettier-ignore*/ import { Construct } from "constructs";
For now there's no "block ignore" in Prettier for JavaScript (only for certain select other languages), although there's an open request for one.
Usually, with prettier or eslint you might want to limit printWidth to defined number of caracter per line. So imagine if you have many imports or long module name :
/* You better should break line overhere |----------| */
import { DepA, DepB, DepC, DepD, DepE, DepF, DepG, DepH, DepI, DepJ } from "./some-long-named-module";
import { OnlyOneImport } from "./other-module";
So my answer is not responding to "how can you align 'from' statements?" but it
may open another question 'should you ?'
Here is a common way to indent imports :
// common way to write import with vertical (Automatable)
import {
DepA,
DepB,
DepC,
DepD,
DepE,
DepF,
DepG,
DepH,
DepI,
DepJ
} from "./some-long-named-module";
import { OnlyOneImport } from "./other-module";
Here is the eslint rule to auto indent your code : https://eslint.org/docs/latest/rules/object-curly-newline
example for object-curly-newline rule in eslint:
# .estlintrc.json
{
...
"rules": {
...
"object-curly-newline": [
"error",
{
"consistent": true,
"multiline": true
}
]
}
}

Here some example of how I use it

eslint no-use-before-define rules does not work in node.js

I use node.js 12.3.0 and i had installed eslint 7.0.0 by npm.
So i wrote the .eslintrc.js like below.
module.exports = {
"env": {
"commonjs": true,
"es6": true,
"node": true
},
"globals": {
"Atomics": "readonly",
"SharedArrayBuffer": "readonly"
},
"parserOptions": {
"ecmaVersion": 12
},
"rules": {
"semi": ["error", "always", {"omitLastInOneLineBlock": true }],
"no-shadow-restricted-names" : "error",
"no-unused-vars": ["warn", { "vars": "all" }],
"no-redeclare": ["error", { "builtinGlobals": true }],
"no-use-before-define": ["error", { "functions": true, "classes": true, "variables": true }]
}
};
As you know, i already added "no-use-before-define" but it didn't work.
All another eslint rules are worked fine but only "no-use-before-define" didn't check anythings.
Here is my examples js file.
let c = qwertqwert(); //As you know qwerqwert is not defined. I want to check this.
a = 123123; //I don't want to allow assign any value to variable before declaration.
b = asdfafasfdasdfas; //Also i need to check any undefined variable or functions are used.
Does "no-use-before-define" can check this?
It seems only can check when i use the variable or function before define or declaration.
Func(); //I use(call) first.
//But the define statement is after.
function Func()
{
return 10;
}
Above code had checked fine by eslint but it is meaningless.
Because i want let eslint to check usage of undefined functions or value.
if you define eslint should show the error you should write a rule like
if you don't want rule you can remove it or skip rule by file
"no-use-before-define": [
"error",
{
"functions": false,
"classes": false,
"variables": false
}
],
NOTE :- i am using extension of airbnb
extends: [
'airbnb-base',
],
it works for me
node js :- 14.17.6
eslint :- 7.12.1+
and if function is not defined then it shows

How to use allow: options with eslintrc.js

I am having the following eslintrc.js:
module.exports = {
extends: ['airbnb-typescript/base'],
parserOptions: {
project: './tsconfig.json',
sourceType: 'module',
},
ignorePatterns: ['*.js'],
rules: {
'no-underscore-dangle': 0,
...
}
};
And I'd like to include some exceptions with allow: [ /** */ ]. But each time when I am adding this as a key: value property in my file, ESLint returns me an error with the following text: unable to use allow on top level. So the question is, how to achieve such results, with allow?
Long story short, I am unable to use my set of rules with MongoDB _id naming, so I have ESLint just to ignore only _id in variable naming, instead of disabling the naming-convention rule itself.
Is there any way to solve this problem?
It works for me:
"no-underscore-dangle": ["error", { allow: ["_id"] }]
If you are using the #typescript-eslint/naming-convention rule, you may also need to add this:
"#typescript-eslint/naming-convention": [
"error",
{
selector: ["variable"],
format: ["strictCamelCase", "PascalCase", "UPPER_CASE"],
filter: {
regex: "^_id$",
match: false,
},
},
],

no-use-before-define wrongly catches use of the global window variable

Working in electron vue-cli project. Trying to upgrade eslint but the default setup has no-use-before-define enabled.
This causes it to catch every use of things like window.process.env.username as an error.
I tried setting my rules as "no-use-before-define": ["error", { "variables": false }], but it didn't help. Adding window as a global also didn't help. Is there a way to fix eslint to be happy with the window variable?
I do like the idea of this feature, so I would like to leave it on if possible. But just turning it off is ok too if that's the best answer.
If it helps, this is my current .eslintrc.js file
// https://eslint.org/docs/user-guide/configuring
module.exports = {
root: true,
parserOptions: {
parser: 'babel-eslint'
},
env: {
browser: true
},
extends: [
// https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention
// consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.
'plugin:vue/essential',
// https://github.com/standard/standard/blob/master/docs/RULES-en.md
'standard'
],
// required to lint *.vue files
plugins: [
'vue'
],
// add your custom rules here
rules: {
// Don't error on variables that are global, like window, not working.
"no-use-before-define": ["error", { "variables": false }],
'generator-star-spacing': 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off',
"vue/html-self-closing": ["error", {
"html": {
"void": "always",
"normal": "any",
"component": "always"
},
"svg": "always",
"math": "always"
}]
}
}
Thanks
-Edit
Tried
globals: {
window: 'writable'
},
But to no effect
