In my Nest js app, i want to add libraries which doesnt have any nest specific implementation. For example sharp or jimp.

I have added these in my project like

npm i jimp.

and imported in my code like this.

import Jimp from 'jimp';

It works fine when i build and serve locally, but when i serve it from docker and build production version, i get the following error :

> planiac@0.0.0 serve /app
backend_1  | > node dist/apps/api/main.js
backend_1  | 
backend_1  | internal/modules/cjs/loader.js:965

Try this instead of import

const jimp = reuire("jimp")

In your Docker, it looks like jimp is not loaded in your node_modules. Try running npm i jimp with the --save option, so that the package is saved into package-lock.json, and make sure your Docker build runs npm install (which it probably already does since you are using Nest)

When you just have the require, like padmakar stated, you won't have the types included. If you want to have type intellisense:

import { default as jimpi } from 'jimp';
const Jimp = require('jimp') as typeof jimpi;
