An Eleventy powered static site using our custom Tachyons build with Postcss for styling.

It’s deployed and hosted by Vercel when the main branch changes using their Github integration - https://pusher-docs.vercel.app

1. Checkout the repo

git checkout [email protected]:pusher/docs.git

2. Install the dependencies via yarn

yarn install

3. Run Eleventy in development mode

yarn run dev

Eleventy watches for any changes and recompiles automatically, it uses BrowserSync behind the scenes to refresh the browser.

If you’ve just checked out the repo, you’ll need to generate the css. You can also leave this running if you intend to change the CSS as you go, it will recompile and 11ty will pick up the changes and reload.

yarn run css

Search is powered by Algolia, on every production build a refreshed index of all content is sent to them.

For users without JS there is a fallback page which is powered by Vercel’s serverless functions.

If you need to debug this you can run the project with vercel dev and it will hot reload any changes.

1. Add a new Markdown file in the relevant directory.
2. Add YAML front matter to the top, you can add a description, which will be used for the page meta but by default it will extract the first 160 characters of the first paragraph. For example:

---
title: Connection — Channels — Pusher Docs
layout: channels.njk
description: Optionally set this to override generated one
eleventyNavigation:
  parent: Using Channels
  key: Connection
---

3. Write up your docs, you can use Markdown, HTML or Nunjucks. Although it’s best to keep it simple and stick to Markdown where possible.

It’s worth having a quick read of this CSS Tricks post about words to avoid

Add the language name just after the triple backticks to get syntax highlighting. We use Prism, the full list of supported languages is here.

Sometimes it’s useful to provide multiple snippets of the same example code in multiple languages. For this we need to sprinkle a little Nunjucks to get things to work. We have a snippets shortcode for this.

To use it open a snippets block and pass an array of languages that matches the markdown code blocks within. Empty lines must be between the nunjucks and markdown code blocks.

{% raw %}

{% snippets ['js', 'rb'] %}

```js
const func = (x) => x^2;
```

```rb
def func(x)
  x^2
end
```

{% endsnippets %}

{% endraw %}

Which will render like this

{% snippets ['js', 'rb'] %}

const func = (x) => x ^ 2;

def func(x)
  x^2
end

{% endsnippets %}

You can change other content when the snippet changed to do this you must add a boolean to the snippet declaration and wrap in container

{% raw %}

{% snippets ['js', 'swift', 'laravelecho'], true %}

```js
pusher.unsubscribe(channelName);
```

```swift
[self.pusher unsubscribeFromChannel:channel];
```

```js
Echo.leaveChannel(channelName);
```

{% endsnippets %}
