ESLint 仅针对特定目录（eslintrc、create-react-app）

Question

I have a folder structure similar to this:

/root
 .eslintrc.json
 package.json
 /someFolder
   /sub
   /sub
 /anotherFolder
 /src
   /containers
   /components
 /oneMoreFolder
   /sub
   /sub

I'm working with create-react-app and am applying airbnb rules. I have been able to run the linter in a specific folder easily from the CLI but on compile, it targets ALL folders.

I want to run the linter on compile on just the files within the /src folder.

How can I go about this? I've tried a number of solutions.

Thank you!

TL:DR How do I target just one subfolder and all of its files on compile when using eslint and create-react-app?

Answer 1

inside your .eslintrc.json

{
  "rules": {
    "quotes": [ 2, "double" ]
  },

  "overrides": [
    {
      "files": [ "src/**/*.js" ],
      "rules": {
        "quotes": [ 2, "single" ]
      }
    }
  ]
}

in .eslintignore

 /someFolder
 /anotherFolder
 /oneMoreFolder

You need to do something like eslint src/**/*.js[x] . If you are running a webpack build(or precommit hook) that does linting check then add it within the scripts object inside package.json .

Answer 3

I used ignorePatterns option. It'll tell ESLint to ignore specific files and directories. It's useful when your IDE (ex. VS Code) is reporting errors in unwanted files.

{
  "ignorePatterns": ["gulpfile.js", "gulp/**/*", "webpack.config.js"]
}

You can Also use the .eslintignore file.

Answer 4

Where you have written the script to run lint in package.json , there only mention the folders you want to target

scripts:{"lint": "eslint src public"}

Then if you want to ignore some type of files in the respective folders, you can mention in ESLint config file.
