Visual Studio 2017 RTM JavaScript IntelliSense not working [closed]

Question

The JavaScript IntelliSense is not working on Visual Studio 2017 RTM editor. I can’t even format the code, nothing is working.

Answer 1

UPDATE: Looks like latest update of VS 2017 (15.3) solve the issue.

This is because of the new javascript language service http://aka.ms/JavaScriptExperimental

To disable and bring back JS, go to: Tools - Options - text editor - Javascript/Typescript - Language service - General and disable the very first option.

Answer 2

Enabling Auto List members helped me:

On the menu go to: Tools > Options >> Text Editor >> All Languages >> General

Uncheck and check back "Auto List Members" to make it a check sign instead of a square Uncheck and check back "Parameter Information" to make it a check sign instead of a square

The problem might be that you have too much JavaScript being analyzed due to particularly large JS libs. You can exclude those from your project with a tsconfig.json file (example below). The only catch is any library you exclude from your project must be explicitly included in the "typeAcquisition" settings in order to get IntelliSense for it.

{
  "compilerOptions": {
    "allowJs": true,
    "noEmit": true,
    "lib": ["es2016", "dom"]  // only necessary if you need new stuff like promises
  },
  "exclude": [
    "wwwroot/lib/" //add folders that contain javascript libraries here
  ],
  "typeAcquisition": {  
    "enable": true,
    "include": [
      "jquery"  // add any libraries excluded in the folders above here
    ]
  }
}

Based on which type Project you're working you must install the jquery or other libraries to be helped by Intellisense.

For exemple: if you're using ASPNET Core and want to be helped with jquery statments, you must add a bower configuration file, and then add a Key/Value pair in this file: "jquery":"version"...

After that, build the Project and enjoy the Intellisense working.
