Eslint 解析器的误报

Question

I am getting a false positive error when running the vue app. It is telling Constructor name should not start with Lower case letter. How to fix this probelm.

My .eslintrc.js is as follows

module.exports = {
  root: true,
  env: {
    browser: true,
    node: true,
  },
  parserOptions: {
    parser: 'babel-eslint',
  },
  extends: [
    '@nuxtjs',
    'prettier',
    'prettier/vue',
    'plugin:vue-scoped-css/recommended',
    'plugin:prettier/recommended',
    'plugin:nuxt/recommended',
  ],
  plugins: ['prettier'],
  // add your custom rules here
  rules: {
    'nuxt/no-cjs-in-config': 'off',
    'no-console': 'off',
    'vue-scoped-css/require-scoped': 'error',
    'vue/component-name-in-template-casing': 'error',
    'prettier/prettier': ['error', { endOfLine: 'auto' }],
  },
}

The error when I am trying to run the app is

$ npm run lint:fix

> v-moa-app@1.0.0 lint:fix
> npm run lint -- --fix


> v-moa-app@1.0.0 lint C:\Users\502622018\moa_workspace\v-moa-app
> eslint --ext .js,.vue --ignore-path .gitignore . "--fix"

The part for which this error is generated is as below:

const decoded = new Buffer.from(encoded, 'base64').toString()

Answer 1

The from property on Buffer is not a constructor. It's just a plain method, so you shouldn't use new with it. See the docs . You need:

const decoded = Buffer.from(encoded, 'base64').toString()
