TS7016

error TS7016: Could not find a declaration file for module ‘uuidjs‘.

Broken Code ❌

1

import UUID = require('uuidjs');

Fixed Code ✔️

The problem shows that uuidjs is a plain JavaScript module and doesn’t ship with TypeScript declaration files (.d.ts). That’s why we have to use the CommonJS import syntax to import this module in a Node.js project:

1

const UUID = require('uuidjs');

A proper fix would be to have a uuidjs.d.ts as part of uuidjs: https://github.com/LiosK/UUID.js/issues/6

Example:

1
2
3

declare class UUID {
  static generate(): string;
}

1
2

import UUID from 'uuidjs';
const id = UUID.generate();
