By default, all commands appear at the Command Bar root. However, in some cases, you may want your command to show up in another context, e.g. when there is an active web page in focus.
Hooks let you achieve this. There is currently only one hook supported – URL Hook.
URL hook allows you to "attach" your command to the "Active Tab" group in the Command Bar. This group appears at the top of the Command Bar root when there is a browser tab in focus.
When your command is run, the page URL will be passed in the url parameter.
A URL Hook is a JSON object with the following properties:
type
required. The type of the hook. Must be "url".
url
Show the command for any URL
Your endpoint can define Hooks by sending a custom HTTP header – X-Slapdash-Hooks. For example, in NodeJS this can look like:
Note, you also need to set Access-Control-Expose-Headers to the list of custom hooks that you want to expose. This ensures Slapdash can access X-Slapdash-Hooks when making a request to your endpoint.
To specify Hooks for Local Commands, you can use code comments in the following format:
The URL match pattern. Allows showing the command only when the page URL matches this pattern. For example, https://github.com/* matches HTTPS URLs only at "github.com", with any URL path and URL query string. Check out for more examples.
You can define Hooks using HTTP Headers for or code comments for . In both cases, the hooks must be string representations of the JSON object. You can define a single Hook or multiple Hooks using an array.
