Slash commands in HipChat can be implemented by making use of Add-ons. HipChat Add-ons are web apps which can be integrated to the HipChat client.

As the doc states:

'A HipChat add-on is just a set of "capabilities" that implement an OAuth based authentication flow, a set of REST APIs, and JavaScript APIs.'

Installation flow

• User begins installation of add-on in the HipChat server.
• HipChat server then retrieves hosted add-on's capabilities descriptor via GET.
• HipChat server registers the consumer and then posts OAuth consumerID/secret via POST to the Add-on.
• This info has to be saved as it will be required to make calls to the HipChat REST API.

You can tell the browser how to execute the scripts. By default, browser runs the script immediately by pausing HTML parsing. Else you can specify async or defer with the script tag to either run script asynchronously or defer it until HTML is parsed.

<script src="script.js"></script>

<script async src="script.js"></script>

<script defer src="script.js"></script>
