Workflows in JavaScript
In YouTrack 2017.2, you can write workflows in JavaScript instead of the domain-specific language that is used in previous versions. You can write a workflow in any IDE that supports JavaScript, pack it into a ZIP file and upload it to YouTrack.
In addition, we've built a web-based workflow editor inside YouTrack. Here, you can write a workflow from scratch without leaving YouTrack.
We’ve added support for action rules. This type of script lets you extend YouTrack with actions that can be applied as commands or accessed directly from the issue toolbar. The new workflows also support custom scripts, which let you better organize and structure your code. Define your own functions and objects and use them in other rules and workflows.
