# 3rd Party Library Installation Simply install your library via `npm install lib-name --save` and import it in your code. If the library does not include typings, you can install them using npm: ```bash npm install d3 --save npm install @types/d3 --save-dev ``` If the library doesn't have typings available at `@types/`, you can still use it by manually adding typings for it: 1. First, create a `typings.d.ts` file in your `src/` folder. This file will be automatically included as global type definition. 2. Then, in `src/typings.d.ts`, add the following code: ```typescript declare module 'typeless-package'; ``` 3. Finally, in the component or file that uses the library, add the following code: ```typescript import * as typelessPackage from 'typeless-package'; typelessPackage.method(); ``` Done. Note: you might need or find useful to define more typings for the library that you're trying to use.
