How to use typescript typing for a legacy project in vscode

Currently I have a project with structure

...
└───folder1
│   │   file011.js
│   │   file012.js
│   └───...
└───folder2
│   │   file021.js
│   └───file022.js
│
└─── files...

I tried to include a type.d.ts to the root, then tried putting it in a typings folder but none worked.

How do I enable typing for my case ? There is no folder with name src

With TypeScript 2.3 you can specify the checkJS option to type check JS files.

It won't work as long as your files are still named "*.js". Try renaming a file to ".ts", then the typescript compiler can do it's magic.

You also have to create a tsconfig.json to configure the typescript compiler.

The settings really depend on the type of project you are using. If you don't use a module system like requirejs, you need to get typings for global modules.

EDIT: Removed reference to Visual Studio project settings as this question is about vscode
