# @astrojs/rss 📖
|
||
|
||
This package brings fast RSS feed generation to blogs and other content sites built with [Astro](https://astro.build/). For more information about RSS feeds in general, see [aboutfeeds.com](https://aboutfeeds.com/).
|
||
|
||
## Installation
|
||
|
||
Install the `@astrojs/rss` package into any Astro project using your preferred package manager:
|
||
|
||
```bash
|
||
# npm
|
||
npm i @astrojs/rss
|
||
# yarn
|
||
yarn add @astrojs/rss
|
||
# pnpm
|
||
pnpm i @astrojs/rss
|
||
```
|
||
|
||
## Example usage
|
||
|
||
The `@astrojs/rss` package provides helpers for generating RSS feeds within [Astro endpoints][astro-endpoints]. This unlocks both static builds _and_ on-demand generation when using an [SSR adapter](https://docs.astro.build/en/guides/server-side-rendering/#enabling-ssr-in-your-project).
|
||
|
||
For instance, say you need to generate an RSS feed for all posts under `src/pages/blog/`. Start by [adding a `site` to your project's `astro.config` for link generation](https://docs.astro.build/en/reference/configuration-reference/#site). Then, create an `rss.xml.js` file under your project's `src/pages/` directory, and use [Vite's `import.meta.glob` helper](https://vitejs.dev/guide/features.html#glob-import) like so:
|
||
|
||
```js
|
||
// src/pages/rss.xml.js
|
||
import rss from '@astrojs/rss';
|
||
|
||
export const get = () => rss({
|
||
title: 'Buzz’s Blog',
|
||
description: 'A humble Astronaut’s guide to the stars',
|
||
items: import.meta.glob('./blog/**/*.md'),
|
||
});
|
||
```
|
||
|
||
Read **[Astro's RSS docs][astro-rss]** for full usage examples.
|
||
|
||
## `rss()` configuration options
|
||
|
||
The `rss` default export offers a number of configuration options. Here's a quick reference:
|
||
|
||
```js
|
||
rss({
|
||
// `<title>` field in output xml
|
||
title: 'Buzz’s Blog',
|
||
// `<description>` field in output xml
|
||
description: 'A humble Astronaut’s guide to the stars',
|
||
// list of `<item>`s in output xml
|
||
items: import.meta.glob('./**/*.md'),
|
||
// (optional) absolute path to XSL stylesheet in your project
|
||
stylesheet: '/rss-styles.xsl',
|
||
// (optional) inject custom xml
|
||
customData: '<language>en-us</language>',
|
||
// (optional) add arbitrary metadata to opening <rss> tag
|
||
xmlns: { h: 'http://www.w3.org/TR/html4/' },
|
||
// (optional) provide a canonical URL
|
||
// defaults to the "site" configured in your project's astro.config
|
||
canonicalUrl: 'https://stargazers.club',
|
||
});
|
||
```
|
||
|
||
### title
|
||
|
||
Type: `string (required)`
|
||
|
||
The `<title>` attribute of your RSS feed's output xml.
|
||
|
||
### description
|
||
|
||
Type: `string (required)`
|
||
|
||
The `<description>` attribute of your RSS feed's output xml.
|
||
|
||
### items
|
||
|
||
Type: `RSSFeedItem[] | GlobResult (required)`
|
||
|
||
Either a list of formatted RSS feed items or the result of [Vite's `import.meta.glob` helper](https://vitejs.dev/guide/features.html#glob-import). See [Astro's RSS items documentation](https://docs.astro.build/en/guides/rss/#generating-items) for usage examples to choose the best option for you.
|
||
|
||
When providing a formatted RSS item list, see the `RSSFeedItem` type reference below:
|
||
|
||
```ts
|
||
type RSSFeedItem = {
|
||
/** Link to item */
|
||
link: string;
|
||
/** Title of item */
|
||
title: string;
|
||
/** Publication date of item */
|
||
pubDate: Date;
|
||
/** Item description */
|
||
description?: string;
|
||
/** Append some other XML-valid data to this item */
|
||
customData?: string;
|
||
};
|
||
```
|
||
|
||
### stylesheet
|
||
|
||
Type: `string (optional)`
|
||
|
||
An absolute path to an XSL stylesheet in your project. If you don’t have an RSS stylesheet in mind, we recommend the [Pretty Feed v3 default stylesheet](https://github.com/genmon/aboutfeeds/blob/main/tools/pretty-feed-v3.xsl), which you can download from GitHub and save into your project's `public/` directory.
|
||
|
||
### customData
|
||
|
||
Type: `string (optional)`
|
||
|
||
A string of valid XML to be injected between your feed's `<description>` and `<item>` tags. This is commonly used to set a language for your feed:
|
||
|
||
```js
|
||
import rss from '@astrojs/rss';
|
||
|
||
export const get = () => rss({
|
||
...
|
||
customData: '<language>en-us</language>',
|
||
});
|
||
```
|
||
|
||
### xmlns
|
||
|
||
Type: `Record<string, string> (optional)`
|
||
|
||
An object mapping a set of `xmlns` suffixes to strings of metadata on the opening `<rss>` tag.
|
||
|
||
For example, this object:
|
||
|
||
```js
|
||
rss({
|
||
...
|
||
xmlns: { h: 'http://www.w3.org/TR/html4/' },
|
||
})
|
||
```
|
||
|
||
Will inject the following XML:
|
||
|
||
```xml
|
||
<rss xmlns:h="http://www.w3.org/TR/html4/"...
|
||
```
|
||
|
||
### canonicalUrl
|
||
|
||
Type: `string (optional)`
|
||
|
||
The base URL to use when generating RSS item links. This defaults to the [`site` configured in your project's `astro.config`](https://docs.astro.build/en/reference/configuration-reference/#site). We recommend using `site` instead of `canonicalUrl`, though we provide this option if an override is necessary.
