In my typescript project, I am using eslint. The files below are in the root, and I have also subfolders /dist and /src.
eslintrc.js
module.exports = {
root: true,
parser: '@typescript-eslint/parser',
parserOptions: {
tsconfigRootDir: __dirname,
project: ['./tsconfig.json'],
},
rules: {
strict: 'error',
semi: ['error', 'always'],
'no-cond-assign': ['error', 'always'],
},
plugins: ['@typescript-eslint'],
extends: [
'eslint:recommended',
'plugin:@typescript-eslint/recommended',
'plugin:@typescript-eslint/recommended-requiring-type-checking',
],
}
tsconfig.json
{
"compilerOptions": {
"outDir": "dist",
"noImplicitAny": true,
"moduleResolution": "Node",
"resolveJsonModule": true,
"module": "ES2020",
"target": "ES2020",
"lib": ["ES2020"],
"allowJs": false,
"alwaysStrict": true
},
"include": ["src"]
}
the word module on top has a red line with this error
Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: .eslintrc.js.
The file must be included in at least one of the projects provided. eslint
How can I fix this?
Update your eslintrc.js to include:
ignorePatterns: ['.eslintrc.js']
same error, this worked for me: https://github.com/nestjs/nest/issues/4900#issuecomment-669743374 https://github.com/nestjs/nest/issues/4900#issuecomment-707330674
looks like config file must be named .eslintrc and use json format instead of .eslintrc.js and parserOptions.createDefaultProgram must be setted to true
The annoying error is basically saying the file eslintrc.js itself is both:
So, ESLint doesn't know what to do and freaks out!
Note that while this file doesn't include your codes, you should decide whether you want this file to be linted (e.g. for tab vs space, or double quote vs single quote,) or not.
You can omit either (1) or (2) from the conflicting situation above.
It's easier. Just add the name of the file (e.g. .eslintrc.js) to .eslintignore.
You can also see case 1.3 of my answer, here for different ways it can be done.
Typescript-ESLint gets the list of files to include from tsconfig.json via parserOptions > project.
So, you can either add the file to the existing tsconfig.json (Solution 2.1) or create a secondary tsconfig.eslint.json to include files like this, that you want to be linted by typescript-eslint, but not necessarily processed by the Typescript compiler.
Solution 2.1: add it to the existing tsconfig.json
// in tsconfig.json ...
"include": [
".eslintrc.js",
// ...
]
Solution 2.2: add it to a separate tsconfig.eslint.json file
Create a file names tsconfig.eslint.json with this content:
// new file: tsconfig.eslint.json
{
"include": [
".eslintrc.js"
]
}
and then inject it into eslintrc.js's parserOptions > project (yes, project accepts both a string, and an array of strings) :
// in eslintrc.js ...
parserOptions: {
project: [
resolve(__dirname, './tsconfig.json'),
resolve(__dirname, './tsconfig.eslint.json'),
],
}
PS. This answer is very similar, I shall give some credit to that.
