# Installation
Get up and running with Freighter by installing the browser extension and choosing the right integration method for your app.
## Prerequisites
1. Install the Freighter browser extension from the [Chrome Web Store](https://chromewebstore.google.com/detail/freighter/bcacfldlkkdogcmkkibnjlakofdplcbk) or [Firefox Add-ons](https://addons.mozilla.org/en-US/firefox/addon/freighter/).
2. Choose an integration method below based on your project setup.
## Choose Your Integration
### npm / yarn
Use this when building with a bundler (Webpack, Vite, etc.) in a React, Next.js, or other modern JS framework.
**Ideal for:**
* React, Vue, Svelte, or Angular applications
* Server-side rendered apps (Next.js, Nuxt)
* Any project using a JavaScript bundler
```bash
npm install @stellar/freighter-api
```
```bash
yarn add @stellar/freighter-api
```
Then import in your code. You can import the entire library:
```javascript
import freighterApi from "@stellar/freighter-api";
```
Or import only what you need:
```javascript
import {
isConnected,
getAddress,
signAuthEntry,
signTransaction,
signMessage,
addToken,
} from "@stellar/freighter-api";
```
> See the [Extension Integration](/extension-freighter-api/extension.md) for the full API reference.
### CDN (script tag)
Use this for plain HTML pages or projects without a build step. The library is loaded directly in the browser.
**Ideal for:**
* Static HTML sites
* Prototypes and quick experiments
* Projects without a bundler
Add to your ``:
```html
```
This always loads the latest version automatically. To pin a specific version:
```html
```
Then access the API via `window.freighterApi`:
```javascript
const { address } = await window.freighterApi.requestAccess();
```
