Using with Browsers
This article assumes you already have a Slipway server up and running. If not, see the Quickstart, and perhaps the Serving Rigs section or the Hosting on Fly.io section.
We'll also assume you've added an API key to the server, and know what it is.
Once you have a Slipway server running, displaying your rigs within a web browser is as simple as navigating to either a Rig, Playlist, or Device endpoint.
For example, if you have a rig called foo and your server is at localhost:8080 then
you can display the Rig in your browser by navigating to:
http://localhost:8080/rigs/foo?authorization=<YOUR_API_KEY>
Where <YOUR_API_KEY> should be replaced with an API key you've added to the server.
When passing an API key as part of the URL is recommended to generate a new API key for this purpose, so that it can be easily rotated later without affecting other devices.
Similarly, if you've configured a playlist called bar or a device called bat, you can render them
by navigating to one of the following URLs:
http://localhost:8080/playlists/bar?authorization=<YOUR_API_KEY>
http://localhost:8080/devices/bat?authorization=<YOUR_API_KEY>
You can watch the progress of your Rig generation in the Slipway server output.
Automatic Refresh
By default the Rig will be served as a PNG image.
When rendering in a browser it may make more sense to request it as an HTML page which
contains an image. This can be done with the query string parameter format=html:
http://localhost:8080/rigs/foo?format=html&authorization=<YOUR_API_KEY>
The advantage of doing this is that Playlists and Devices (which reference playlists)
also generate a refresh interval, and when requesting either a Playlist or Device as HTML
Slipway uses a <meta http-equiv="refresh" content="REFRESH_INTERVAL"> tag to request
that the browser automatically refreshes the page after REFRESH_INTERVAL seconds.
You will be able to see this <meta> tag added within the <head> tag of the returned HTML
if you request a playlist:
http://localhost:8080/playlists/bar?format=html&authorization=<YOUR_API_KEY>
When the interval elapses, the browser should automatically refresh the page, requesting a new screen.
