In typescript, how to do import merge from "lodash/merge"

Actually you can import a single function using the 'lodash.merge' library

import merge from 'lodash.merge'

const result: any = merge(obj1, obj2)

BUT

You need to add this property to the tsconfig.json "esModuleInterop": true without this it will not work

Update

The modern way to do that is to use the individual packages. e.g. for merge you would install and use lodash.merge i.e.

import merge from 'lodash.merge'

PS: Ensure "esModuleInterop": true is in your tsconfig.json as its needed for the ES default import of merge to work.

Old Answer

Cannot find module "lodash/merge". How to solve it

The definitions for TypeScript don't support individual loading of lodash members. So you can only import * as _ from "lodash".
