Version Packages

By default, the sidebar nav redirects clicks on category headings to
their first child.

To disable those redirects, override
`_includes/_joiningBlocks/_layoutSidebar/sidebar/20-navigation.njk`
and add the `no-redirects` attribute to the `<rocket-navigation>`
element.

+# Configuration >> Images ||40
+
+Rocket does handle content images automatically by
+
+- producing multiple sizes so users download images that are meant for their resolution
+- outputting multiple formats so the device can choose the best image format it supports
+
+And the best thing about is you don't need to do anything.
+
+## Usage
+
+If you are using markdown images you are good to go.
+
+```md
+![My Image](path/to/image.jpg)
+```
+
+will result in
+
+```html
+<picture>
+  <source
+    type="image/avif"
+    srcset="/images/5f03d82-300.avif 300w, /images/5f03d82-820.avif 820w"
+    sizes="(min-width: 1024px) 820px, calc(100vw - 20px)"
+  />
+  <source
+    type="image/jpeg"
+    srcset="/images/5f03d82-300.jpeg 300w, /images/5f03d82-820.jpeg 820w"
+    sizes="(min-width: 1024px) 820px, calc(100vw - 20px)"
+  />
+  <img
+    alt="My Image"
+    rocket-image="responsive"
+    src="/images/5f03d82-300.jpeg"
+    width="300"
+    height="158"
+    loading="lazy"
+    decoding="async"
+  />
+</picture>
+```
+
+## Benefits
+
+The main benefit is that we can serve the correct size and optimal image format depending on the browser capabilities leading to optimal loading times on different systems.
+
+- Smaller images for smaller screens
+
+  When providing `srcset` and `sizes` the browser can decide which image makes the most sense to download.
+  This will lead to much faster websites especially on mobile where smaller images can be served.
+  If you wanna know more check out [The anatomy of responsive images](https://jakearchibald.com/2015/anatomy-of-responsive-images/).
+
+- Serve the best/smallest image format the browser understands
+
+  There are currently ~3 formats you may want to consider `avif`, `webp` and `jpg`. The improvements are huge [webp is ~30% and avif ~50%](https://www.ctrl.blog/entry/webp-avif-comparison.html) smaller then the original jpg.
+
+## Adding a caption
+
+If you want to describe your image in more detail you can add a caption
+
+```md
+![My Image](path/to/image.jpg 'My caption text')
+```
+
+will result in
+
+```html
+<figure>
+  <picture>
+    <!-- picture code the same as above -->
+  </picture>
+  <figcaption>My caption text</figcaption>
+</figure>
+```
+
+## Adjusting options
+
+Under the hood it is using [11ty/image](https://www.11ty.dev/docs/plugins/image/) and all it's options are available.
+
+<inline-notification type="tip">
+
+If you are using a layout preset like `@rocket/launch` then you probably don't want to touch/change these options as the preset will set it for you accordion to its layout needs.
+
+The default preset for regular markdown content is available as `responsive`.
+
+</inline-notification>
+
+👉 `rocket.config.js`
+
+```js
+export default {
+  imagePresets: {
+    responsive: {
+      widths: [300, 820],
+      formats: ['avif', 'jpeg'],
+      sizes: '(min-width: 1024px) 820px, calc(100vw - 20px)',
+    },
+  },
+};
+```
+
+## Defining your own presets
+
+You can add your own image preset like so
+
+```js
+export default {
+  imagePresets: {
+    'my-image-preset': {
+      widths: [30, 60],
+      formats: ['avif', 'jpeg'],
+      sizes: '(min-width: 1024px) 30px, 60px',
+    },
+  },
+};
+```
+
+Once that `imagePreset` is defined you can use it by adding it to any `img` tag.
+
+```html
+<img src="./path/to/image.jpg" alt="my alt" rocket-image="my-image-preset" />
+```
+
+## How does it work?
+
+1. Each markdown image `![my image](path/to/image.jpg)` gets rendered as `<img src="path/to/image.jpg" alt="my image" rocket-image="responsive">`
+2. We parse the html output and process every image which has `rocket-image`
+3. Get the image preset settings from the name e.g. `rocket-image="my-image-preset"` reads `imagePreset['my-image-preset']`
+4. Pass the settings onto `@11ty/image` to generate the image sizes and formats
+5. With the metadata we render the html
+
+## Default Formats
+
+An [image file format](https://en.wikipedia.org/wiki/Image_file_formats) is a way of storing common image formats. Each format varies in capabilities like compression algorithm, availability, progressive rendering, encode and decode time, ...
+Ultimately newer formats are usually smaller while retaining image quality which leads to faster websites.
+
+By default, we generate `avif` and `jpg` because
+
+- we only want to generate two versions to limit CI time and html size
+- `avif` is significantly smaller than `webp`
+- `avif` is available in
+  - Chrome since August 2020
+  - Firefox since June 2021
+- `jpg` as a fallback for Edge, Safari, IE11
+- `webp` would only help a small percentage of Edge & Safari on macOS 11 (Big Sur) users
+
+This leads to the following situation:
+
+- Chrome, Firefox gets the small `avif`
+- Edge, Safari, IE11 gets the bigger `jpg`
+
+To learn more about `avif` take a look at [AVIF has landed](https://jakearchibald.com/2020/avif-has-landed/).
+
+If you want to add `webp` (or replace `avif` with it) you can do so by setting the formats
+
+👉 `rocket.config.js`
+
+```js
+export default {
+  imagePresets: {
+    responsive: {
+      formats: ['avif', 'webp', 'jpeg'],
+    },
+  },
+};
+```
+
+## Default widths
+
+In order to understand the need for having a single image in multiple resolutions we need to understand the our website is served to many different environments and each may come with its own specific device pixel ratio (DPR). The device pixel ratio is the ratio between physical pixels and logical pixels. For instance, the Galaxy S20 report a device pixel ratio of 3, because the physical linear resolution is triple the logical linear resolution.
+
+Physical resolution: 1440 x 3200
+Logical resolution: 480 x 1067
+
+And 1440 / 480 = 3.
+
+By default, we generate the following widths `600`, `900` and `1640` because
+
+- we only want to generate a small amount of widths to limit CI time and service worker cache size
+- `600` is good for mobile with DRP 2
+- `900` is good for mobile with DRP 3 and desktop with DPR of 1
+- `1640` is good for desktop with DPR of 2
+
+If you want to add more widths you can add them to `widths`.
+
+👉 `rocket.config.js`
+
+```js
+export default {
+  imagePresets: {
+    responsive: {
+      widths: [300, 600, 900, 1200, 1640],
+      sizes: '(min-width: 1024px) 820px, calc(100vw - 20px)',
+    },
+  },
+};
+```
+
+<inline-notification type="tip">
+
+As an end user in most cases you don't want to mess with this as a layout preset should set this for you. If you are building your own layout preset then be sure to set `widths` and `sizes` via `adjustImagePresets`
+
+```js
+export function myPreset() {
+  return {
+    adjustImagePresets: imagePresets => ({
+      ...imagePresets,
+      responsive: {
+        ...imagePresets.responsive,
+        widths: [600, 900, 1640],
+        sizes: '(min-width: 1024px) 820px, calc(100vw - 40px)',
+      },
+    }),
+  };
+}
+```

+# Configuration >> Service Worker ||30
+
+Rocket does come with a default service worker that will
+
+- cache already visited pages
+- cache assets of visited pages (up to 100 files then it replaces older entries)
+- reload the page if a newer html page version is available on service worker activation
+
+## Adjusting the file name
+
+Changing the service worker file name can be quite a hassle so you can adjust generate file name via a config.
+
+👉 `rocket.config.js`
+
+```js
+export default {
+  serviceWorkerName: 'my-service-worker-name.js',
+};
+```
+
+## Meet the Service Worker
+
+The default service worker will work for many scenarios however your needs my vary.
+To enable different service worker strategies you can replace the default service worker code by providing a file at `_assets/service-worker.js`.
+This file will be auto transformed and generated in the root of the website using the defined `serviceWorkerName`.
+
+For inspiration, you can take a look at the default config.
+
+[https://github.com/modernweb-dev/rocket/blob/main/packages/cli/preset/\_assets/service-worker.js](https://github.com/modernweb-dev/rocket/blob/main/packages/cli/preset/_assets/service-worker.js)

+
+## Setup Simulation Mode
+
+For simulation mode we need a dedicated html file that will be used as an iframe target while loading stories.
+
+The fastest way to create such a file is to use the `layout-simulator` layout.
+
+Create a file `docs/simulator.md` with the following content.
+
+```md
+---
+layout: layout-simulator
+eleventyExcludeFromCollections: true
+excludeFromSearch: true
+---
+```
+
+Once you have that you need to configure it for the story renderer by setting it in your `rocket.config.js`.
+
+```js
+export default {
+  setupUnifiedPlugins: [
+    adjustPluginOptions('mdjsSetupCode', {
+      simulationSettings: { simulatorUrl: '/simulator/' },
+    }),
+  ],
+};
+```
+
+<inline-notification type="tip">
+
+You can freely choose the path for the "simulator" by creating the md file in a different folder and adjusting the path in the config.
+
+</inline-notification>
+
+## Simulator states
+
+To simulate these stats that usually come from the device itself we put those infos on the document tag.
+
+We can simulate the following settings
+
+1. `platform`
+   Adopting styles and behavior depending on which device platform you are.
+   ```html
+   <html platform="web"></html>
+   <html platform="android"></html>
+   <html platform="ios"></html>
+   <!-- potentially later -->
+   <html platform="web-windows"></html>
+   <html platform="web-mac"></html>
+   ```
+2. `theme`
+   Adjust your styles based on a theme - light/dark are the default but you can add as many as you want.
+   ```html
+   <html theme="light"></html>
+   <html theme="dark"></html>
+   ```
+3. `language`
+   Best to relay on `data-lang` as `lang` often gets changes by translations services which may interfere with your translation loading system.
+   ```html
+   <html lang="en-US" data-lang="en-US"></html>
+   <html lang="de-DE" data-lang="de-DE"></html>
+   ```
+
+If you want to react to such document changes you can use an [MutationObserver](https://developer.mozilla.org/de/docs/Web/API/MutationObserver).
+
+For a vanilla web component it could look something like this:
+
+```js
+class DemoElement extends HTMLElement {
+  constructor() {
+    super();
+    this.attachShadow({ mode: 'open' });
+
+    this.platform = 'the web';
+    this.language = 'en-US';
+    this.theme = 'light';
+
+    this.observer = new MutationObserver(this.updateData);
+  }

+
+## 0.8.0
+
+### Minor Changes
+
+- 8bba4a8: Every content image in markdown will outputted in multiple widths and formats to ensure small image file sizes while retaining quality.
+  You can adjust the defaults by setting `imagePresets.responsive`.
+
+  ```js
+  export default {
+    imagePresets: {
+      responsive: {
+        widths: [600, 900, 1640],
+        formats: ['avif', 'jpeg'],

+    },
+  };
+  ```
+
+## 0.7.0
+
+### Minor Changes
+
+- 2724f07: The service worker no longer precaches all urls and assets. It now
+
+  - caches already visited pages
+  - caches assets of visited pages (up to 100 files then it replaces older entries)
+  - on service worker activation it will reload the page if a newer version is available

 # @rocket/eleventy-rocket-nav
 
+## 0.3.0
+
+### Minor Changes
+
+- ef8ebb0: To support dynamically created content to be part of the anchor navigation of the page we now analyze the final html output instead of `entry.templateContent`.
+
+  BREAKING CHANGE:
+
+  - only add anchors for the currently active pages (before it added anchor for every page)
