# Astro SW
|
||||
|
||||
[](https://www.npmjs.com/package/@ayco/astro-sw)
|
||||
[](https://www.npmjs.com/package/@ayco/astro-sw)
|
||||
|
||||
Use your own authored [service worker](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API) with Astro.
|
||||
|
||||
The integration accepts the path to your service worker and automatically injects dynamic variables such as `__assets` generated by Astro for caching.
|
||||
|
||||
It works on all Astro output options: `static`, `server`, or `hybrid`, and lets developers retain the flexibility for various [caching strategies](https://developer.chrome.com/docs/workbox/caching-strategies-overview/).
|
||||
|
||||
## Background
|
||||
|
||||
This integration was originally developed to support the Caching strategy needs of [Cozy](https://cozy.pub) -- the modern reading companion for the Web. You can find [an example service worker in the repository](https://github.com/ayoayco/Cozy/blob/main/src/sw.mjs).
|
||||
|
||||
There is a work in progress adding `presets` for using common caching strategies and customizing the behavior of the service worker via config options. This aims to reduce the need for writing the service worker script by hand for most use cases.
|
||||
|
||||
Get in touch:
|
||||
1. Chat via Discord: [Ayo's Projects](https://discord.gg/kkvW7GYNAp)
|
||||
1. Submit tickets via [SourceHut todo](https://todo.sr.ht/~ayoayco/astro-sw)
|
||||
1. Start a [GitHub discussion](https://github.com/ayoayco/astro-sw/discussions)
|
||||
1. Email me: [ayo@ayco.io](mailto:ayo@ayco.io)
|
||||
|
||||
## Installation
|
||||
|
||||
In your [Astro](https://astro.build) project:
|
||||
|
||||
```bash
|
||||
# if using npm
|
||||
$ npm i @ayco/astro-sw
|
||||
|
||||
# if using pnpm
|
||||
$ pnpm add @ayco/astro-sw
|
||||
```
|
||||
|
||||
## Minimal Usage
|
||||
|
||||
Here's an example `astro.config.mjs` file:
|
||||
|
||||
```js
|
||||
import { defineConfig } from "astro/config";
|
||||
import serviceWorker from "@ayco/astro-sw";
|
||||
|
||||
export default defineConfig({
|
||||
integrations: [
|
||||
serviceWorker({
|
||||
path: "./src/sw.ts",
|
||||
}),
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
For more options available, see the [API](#api).
|
||||
|
||||
## TypeScript support
|
||||
|
||||
We use `esbuild` to resolve service worker `imports` and build TS files! You can customize the build options by providing it to the `esbuild` configuration property.
|
||||
|
||||
```js
|
||||
import { defineConfig } from "astro/config";
|
||||
import serviceWorker from "@ayco/astro-sw";
|
||||
|
||||
export default defineConfig({
|
||||
integrations: [
|
||||
serviceWorker({
|
||||
path: "./src/sw.ts",
|
||||
esbuild: {
|
||||
minify: true,
|
||||
},
|
||||
}),
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
## Injected variables
|
||||
|
||||
The most important variable your service worker will have access to is `__assets`, which contains all routes and public assets that Astro includes in your build. Additionally, you will also get `__prefix` and `__version` you can use for naming & invalidating your Cache storage (useful for debugging purposes).
|
||||
|
||||
## `eslint` globals
|
||||
|
||||
Because of the injected variables not being defined in your script, you might get `eslint` errors for the undefined variables when you have the `no-undef` rule. To prevent this, you can use our exported `globals` object in your eslint config as follows:
|
||||
|
||||
```js
|
||||
import astroSwGlobals from "@ayco/astro-sw/globals";
|
||||
|
||||
export default [
|
||||
{
|
||||
languageOptions: {
|
||||
globals: {
|
||||
...astroSwGlobals,
|
||||
},
|
||||
},
|
||||
},
|
||||
// add more generic rule sets here, such as:
|
||||
// jsPlugin.configs.recommended,
|
||||
];
|
||||
```
|
||||
|
||||
## Registration Hooks
|
||||
|
||||
Hooks are provided for adding custom logic that triggers in various service worker registration events.
|
||||
|
||||
The following properties are available for the `registrationHooks` configuration:
|
||||
|
||||
1. `installing` - when the registration is 'installing'
|
||||
1. `waiting` - when the registration is 'waiting'
|
||||
1. `active` - when the registration is 'active'
|
||||
1. `error` - when the registration throws an error
|
||||
1. `unsupported` - when the service workers are unsupported
|
||||
1. `afterRegistration` - after the registration succeeds
|
||||
|
||||
```js
|
||||
import { defineConfig } from "astro/config";
|
||||
import serviceWorker from "@ayco/astro-sw";
|
||||
|
||||
export default defineConfig({
|
||||
integrations: [
|
||||
serviceWorker({
|
||||
path: "./src/sw.ts",
|
||||
registrationHooks: {
|
||||
afterRegistration: async () => {
|
||||
const sw = await navigator.serviceWorker.getRegistration();
|
||||
console.log(">>> registrered", sw);
|
||||
},
|
||||
installing: () => console.log("installing..."),
|
||||
waiting: () => console.log("waiting..."),
|
||||
active: () => console.log("active..."),
|
||||
error: (error) => console.error(error),
|
||||
unsupported: () => console.log(":("),
|
||||
},
|
||||
}),
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
The integration accepts a configuration object with the following properties
|
||||
|
||||
| property | type | required? | notes |
|
||||
| ------------------- | ---------------------------------------------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| path | string | required | path to your _own_ service worker script; no surprises & easy debugging |
|
||||
| assetCachePrefix | string | optional | cache storage name prefix |
|
||||
| assetCacheVersionID | string | optional | cache storage name versioning; by default, a random UUID is used |
|
||||
| customRoutes | string[] | optional | list of custom routes you want to be cached. Beware that non-existent routes that result to HTTP Error404 will cause the service worker to fail |
|
||||
| excludeRoutes | string[] | optional | list of routes you want to be ignored/removed from assets |
|
||||
| logAssets | boolean | optional | set to see a list of the assets found; defaults to false |
|
||||
| esbuild | [BuildOptions](https://esbuild.github.io/api/) | optional | custom build options for your service worker script |
|
||||
| registrationHooks | object | optional | provide callbacks for various registration events; see section on [Registration Hooks](#registration-hooks) |

title: Building a Cozy Web
|

description: Let us build the web we want!

|

|
||||
> This was originally posted on [Ayo's Blog](https://ayos.blog/building-a-cozy-web).
|
||||
|
||||
Have you ever clicked a link to an article, all hyped up to read the content, only to be slapped in the face with popups over popups of requests to subscribe and asking consent to track you with cookies?
|
||||
|
||||
Do you sometimes wish you can have a consistent experience when opening articles... a place to save all your favorites, and possibly get helpful insights?
|
||||
|
||||
Ah, well you're not alone. 🤣
|
||||
|
||||
This is exactly why I started [**Cozy** 🧸](https://cozy.ayco.io/).
|
||||
|
||||
It's a simple web page that can make any web page content-focused! 🎉
|
||||
|
||||
It uses a library called [@extractus/article-extractor](https://www.npmjs.com/package/@extractus/article-extractor) to fetch and extract just the content.
|
||||
|
||||
Then with [Astro](https://astro.build), we can server-side render the page so your browser only gets clean HTML!
|
||||
|
||||
No nonsense. No headaches.
|
||||
|
||||
The project and the road map for features are all public on my [GitHub](https://github.com/ayoayco/cozy-reader)
|
||||
|
||||
## Cozy Features
|
||||
|
||||
Right now, it successfully extracts the content and delivers a clean page to your browser.
|
||||
|
||||
I'm working toward bringing the following in the coming weeks:
|
||||
1. Save favorites to a library
|
||||
2. Offline access
|
||||
3. Smart Insights about the article
|
||||
4. Easier usage (browser extensions or apps?)
|
||||
|
||||
## Coziest Usage
|
||||
|
||||
The most convenient way to use it right now is through what we call a browser bookmarklet.
|
||||
|
||||
Basically you can have a button there beside your other bookmarks that will open the current page in Cozy.
|
||||
|
||||
You can create this new bookmark titled 'Get cozy!' and put the following as value for the URL:
|
||||
|
||||
```js
|
||||
javascript:(function(){ window.open('https://cozy.ayco.io/?url=%27 + window.location.href, %27_self%27); })();
|
||||
```
|
||||
|
||||
This is possible on all major browsers, including Safari on iOS (where I personally use this often). Some screenshots:
|
||||
|
||||
| Firefox | Chrome |
|
||||

|
||||
|  |  |
|
||||
|
||||
## Join the Project!
|
||||
|
||||
I'm sure this looks very simple, but I think this is the most exciting hobby project I've started yet.
|
||||
|
||||
There's a lot that happened and a lot of problems could have been avoided if people were equipped to assess the content they find online.
|
||||
|
||||
I think there's lots of good a simple tool could bring if it allows users to cut-through all the distractions and are presented with unbiased and accurate information.
|
||||
|
||||
This project is a groundwork for this experience.
|
||||
|
||||
Let's build the web we want! 🧸
