How to enable autocomplete for Google Apps Script in locally-installed IDE

Question

I\'m trying to build GAS projects locally using clasp.

Any locally-installed IDE is a huge improvement over Google\'s Script Editor, so the tool looks very promising

This answer is a minor variation on the accepted one for IDEs/extensions which support Typescript auto completion based on tsc/tsserver:

• Install TypeScript and @types/google-apps-script

  • https://www.npmjs.com/package/typescript
  • https://www.npmjs.com/package/@types/google-apps-script

• Create a jsconfig.json file in your local project directory:

  { 
      "compilerOptions": {
          "checkJs": true
        }
  }    
  

• Alternatively, If you're using typescript along with javascript, then create a tsconfig.json:

  { 
      "compilerOptions": {
          "allowJs": true,
          "checkJs": true,
          "types": ["google-apps-script"]
        }
  }    
  

• Include both filenames in .claspignore, if you're using clasp and if the file is in your local directory.

• You can also use any of this config globally, if the config is in your home/parent directory, as tsc searches for this config from project/local folder to root(in which case, you don't need to include it in .claspignore).
