How to read from .json files from TypeScript / Angular

Locate, or create, your typings.d.ts file and add the following lines:

declare module "*.json" {
  const value: any;
  export default value;
}

Otherwise you will get an error saying the compiler can’t find module filename.json.

Then you can include a .json file in your project. For example this file:

{
  "version": "6.01"
}

And you can read from such a file like this:

import * as versionData from '../version.json';

// ...

if (versionData && (versionData).version) {
      this.version = (versionData).version;
}
