# @astrojs/netlify
This adapter allows Astro to deploy your SSR site to [Netlify](https://www.netlify.com/).
Learn how to deploy your Astro site in our [Netlify deployment guide](https://docs.astro.build/en/guides/deploy/netlify/).

## Why Astro Netlify
If you're using Astro as a static site builder—its behavior out of the box—you don't need an adapter.
If you wish to [use server-side rendering (SSR)](https://docs.astro.build/en/guides/server-side-rendering/), Astro requires an adapter that matches your deployment runtime.
[Netlify](https://www.netlify.com/) is a deployment platform that allows you to host your site by connecting directly to your GitHub repository. This adapter enhances the Astro build process to prepare your project for deployment through Netlify.
## Installation
Add the Netlify adapter to enable SSR in your Astro project with the following `astro add` command. This will install the adapter and make the appropriate changes to your `astro.config.mjs` file in one step.
```sh
# Using NPM
npx astro add netlify
# Using Yarn
yarn astro add netlify
# Using PNPM
pnpm astro add netlify
```
If you prefer to install the adapter manually instead, complete the following two steps:
1. Install the Netlify adapter to your projects dependencies using your preferred package manager. If youre using npm or arent sure, run this in the terminal:
```bash
npm install @astrojs/netlify
```
1. Add two new lines to your `astro.config.mjs` project configuration file.
```js title="astro.config.mjs" ins={2, 5-6}
import { defineConfig } from 'astro/config';
import netlify from '@astrojs/netlify/functions';
export default defineConfig({
output: 'server',
adapter: netlify(),
});
```
### Edge Functions
Netlify has two serverless platforms, Netlify Functions and [Netlify's experimental Edge Functions](https://docs.netlify.com/netlify-labs/experimental-features/edge-functions/#app). With Edge Functions your code is distributed closer to your users, lowering latency. You can use Edge Functions by changing the `netlify/functions` import in the Astro config file to use `netlify/edge-functions`.
```js title="astro.config.mjs" ins={3} del={2}
import { defineConfig } from 'astro/config';
import netlify from '@astrojs/netlify/functions';
import netlify from '@astrojs/netlify/edge-functions';
export default defineConfig({
output: 'server',
adapter: netlify(),
});
```
## Usage
[Read the full deployment guide here.](https://docs.astro.build/en/guides/deploy/netlify/)
After [performing a build](https://docs.astro.build/en/guides/deploy/#building-your-site-locally) the `netlify/` folder will contain [Netlify Functions](https://docs.netlify.com/functions/overview/) in the `netlify/functions/` folder.
Now you can deploy. Install the [Netlify CLI](https://docs.netlify.com/cli/get-started/) and run:
```sh
netlify deploy --build
```
The [Netlify Blog post on Astro](https://www.netlify.com/blog/how-to-deploy-astro/) and the [Netlify Documentation](https://docs.netlify.com/integrations/frameworks/astro/) provide more information on how to use this integration to deploy to Netlify.
## Configuration
To configure this adapter, pass an object to the `netlify()` function call in `astro.config.mjs` - there's only one possible configuration option:
### dist
We build to the `dist` directory at the base of your project. To change this, use the `dist` option:
```js
import { defineConfig } from 'astro/config';
import netlify from '@astrojs/netlify/functions';
export default defineConfig({
output: 'server',
adapter: netlify({
dist: new URL('./dist/', import.meta.url)
})
});
```
And then point to the dist in your `netlify.toml`:
```toml
[functions]
directory = "dist/functions"
```
### binaryMediaTypes
> This option is only needed for the Functions adapter and is not needed for Edge Functions.
Netlify Functions requires binary data in the `body` to be base64 encoded. The `@astrojs/netlify/functions` adapter handles this automatically based on the `Content-Type` header.
We check for common mime types for audio, image, and video files. To include specific mime types that should be treated as binary data, include the `binaryMediaTypes` option with a list of binary mime types.
```js
import fs from 'node:fs';
export function get() {
const buffer = fs.readFileSync('../image.jpg');
// Return the buffer directly, @astrojs/netlify will base64 encode the body
return new Response(buffer, {
status: 200,
headers: {
'content-type': 'image/jpeg'
}
});
}
```
