Generate Typescript definitions from a Javascript file

Question

Is there any way to generate Typescript definitions from a NodeJS/Javascript file ?

I have file which looks like :

module.exports = {
  account_a: {
    name: 'a',
    title: 'Account a',
  },
  account_n: {
    name: 'n',
    title: 'Account n',
  },
  // and so on
};

and would like to generate some Typescript definitions of it.

Actually, I'm copy/pasting its content to a TS file and compile it using tsc --declaration . but it's not ideal, any idea ?

I tried the solutions provided in this topic but it's not really what I am trying to achieve, I don't want to generate a .ts file, only its defintions — Léo Georges

Does this answer your question? How do you produce a .d.ts "typings" definition file from an existing JavaScript library? — jaspenlind

Sounds like tsc --allowJs --declaration file.js is what I'm looking for, thank you — Léo Georges

actually you can using in TypeScript this below code

**exports** = {
      account_a: {
        name: 'a',
        title: 'Account a',
      },
      account_n: {
        name: 'n',
        title: 'Account n',
      },
      // and so on
    };
