npm install eslint //For a local install
 or 
npm install -g eslint //For a global install.

2) Then, open Setting.json file in VS code. by File-> Preferences->Settings.

3) Add following setting.

 {
    "eslint.enable": true,
    "eslint.autoFixOnSave": true,
    "eslint.run": "onType",
    "eslint.options": {
        "extensions": [".js",".vue"]
    },
    "eslint.validate": [
      "javascript",
      "javascriptreact",
     {
      "language": "html",
      "autoFix": true
     },
     { "language": "vue", "autoFix": true },
     { "language": "js", "autoFix": true }
   ],
