While we recommend using our templates to get started, you can also install the API client manually.

​
As a <script> import

Start using the Extensions API client by inserting this code into the <head> tag of your HTML: 
<script src="https://unpkg.com/@replit/extensions@1.8.0/dist/index.global.js"></script>
Start using the API client by creating a new <script> tag and using the pre-defined replit variable. 
<script>
  async function main() {
    await replit.init();

    ...
  }

  window.addEventListener('load', main);
</script>

​
As an npm package

Install the client with your preferred package manager, and use the import statement to start using it. 
npm install @replit/extensions
yarn add @replit/extensions
pnpm add @replit/extensions
After installing the API client, use the import statement to start using it. 
import {
  fs,
  data,
  ...
} from '@replit/extensions';
