为什么eslint无法检测目录中的所有文件，但可以检测单个文件？

Question

This is my directory structure.

I want to config some eslint rule to detect my code.

In .eslintrc , I write these configuration items.

{
  "extends": "airbnb",
  "rules": {
    "valid-jsdoc": 2,
    // Disable until Flow supports let and const
    "no-var": 0,
    "react/jsx-uses-react": 1,
    "react/jsx-no-undef": 2,
    "react/wrap-multilines": 2,
    "func-names": 0,
    "new-cap": 0,
    "no-undef": 0,
  },
  "plugins": [
    "react"
  ]
}

I have used npm script to run eslint.

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

Normally, when I run npm run lint , it will detect all the files in src directory.

But, unfortunately, nothing output.

I don't know why. I guess maybe I have writed wrong configuration items. But after I write npm scripts "lint": "eslint src/component/App.jsx" , eslint works.

So where is the problems? Eslint can detect single file well, but it can't detect all the files in some directory.

when you run eslint src , by default its looking for all the files with .js extension. I think in your case you want to change command to eslint src --ext .js,.jsx . This will look for all the files inside src with .js and/or .jsx extensions. (personally recommend)

If you want to use glob to solve this issue then you can change your cmd to eslint src/**/*.jsx
