Where can I find the @types for a specific lodash package?

Seeking to utilize a specific function from lodash - assignin. I have successfully installed lodash.assignin and incorporated it into my project:

import assignIn = require('lodash.assignin');

However, when compiling, an error occurs: "error TS2307: Cannot find module 'lodash.assignin'".

I recognize the need for typings related to the lodash.assignin package, but only the lodash/assignin type is available in @types/lodash.

I am hesitant to install the entire lodash package simply for one of its functions. Is there a way for lodash to provide typings for individual packages?

Answer №1

Sorry, but the package lodash.assignin is not available. You can find a list of available lodash packages here.

For instance, if you want to use the method first, you will need to install it by running npm i --save lodash.first. After installing, you can use the method in your code like this: 

const first = require('lodash.first');

Answer №2

After much experimentation, I finally cracked this puzzle by applying the following solution to a different package:

src/types/lodash.groupby.d.ts:

import { groupBy } from 'lodash'

export default groupBy


yarn add -D '@types/lodash@^4.6.0'

To utilize this, import as follows:

import groupBy from 'lodash.groupby'

This setup is tested with TypeScript 2.9.
