Is there a way to import just one function from lodash? I attempted it like this:
import get from 'lodash/get';
Even after installing both lodash and @types/lodash, I encountered the following error message:
@types/lodash/get/index"' has no default export.)
To streamline your lodash imports in TypeScript, you can easily bring in a single function like this:
import isEqual from 'lodash/isEqual';esModuleInterop flag in your compiler options (tsconfig.json).
Here is an example configuration:
{
"compilerOptions": {
"module": "commonjs",
"target": "es5",
"lib": ["es6", "dom"],
"moduleResolution": "node",
"esModuleInterop": true,
...
}
}
I faced the same issue and found my solution here.
Here is what you need to do:
Make sure to install lodash-es
npm install --save lodash-es
Instead of using the regular lodash

Update 1: Although it should be simpler,
Step 1: Install typings
npm i -D @types/lodash-es
Step 2: Import from "lodash-es" instead of just "lodash"
Step 3: Import in this way for better results (to avoid a larger bundle size)
import orderBy from 'lodash-es/orderBy';
I have successfully implemented the necessary steps to ensure the functionality of lodash.random, and I believe this approach will also be effective for lodash.get:
npm install --save lodash.randomnpm install --save-dev @types/lodash.randomcompilerOptions.allowSyntheticDefaultImportstrue in your tsconfig.jsonimport { random } from 'lodash';In order to solve this issue, I found that the only way was:
import get = require("lodash.get");You can find a similar example here.
The alternative suggestion of
import * as get from 'lodash.get';Even with the following in my tsconfig.json:
"allowSyntheticDefaultImports": true,
"esModuleInterop": true
It still fails (not for React, moment, and other packages, but specifically for the lodash.get package). So, using require may not look pretty, but it gets the job done (albeit at the expense of breaking ES6 import syntax).
After encountering a comparable error, I was able to resolve it with the following solution:
import * as retrieve from 'lodash.get';
If you want to access the functionality, you have two options:
import { get } from "lodash";
Alternatively, you can use:
import { get } from "lodash-es";
To utilize the latter option, you will need to install the appropriate typing file (which includes the default export):
npm install @types/lodash-es --save-dev
