Checklist for Jira Cloud, built with Forge

This is a demo app built with Atlassian Forge that adds a checklist panel to Jira issues. The app shows off some platform capabilities and is intended to be used as educational material.

Forge is Atlassian's new hosted Functions-as-a-Service platform. You can write functions in a subset of Node within the context of Confluence and Jira and return React-like UI components.

Features

Create, check/uncheck and delete list items
Simple concurrency handling, when multiple people are modifying the same list

Limitations

The current Forge UI components have limited configuration options, particularly around layout and user event handling
The UI actions have noticeable latency, even in production mode

Quick start

Set up Forge (request Beta access here)
Build and deploy the app by running:

forge deploy

Install the app in a Jira Cloud site by running:

forge install

To proxy app invocations to your development local environment:

forge tunnel

Architecture

The app implements an Issue Panel with a simple UI that contains a Form with a TextField for new item entry and a Table component to render the list (this is currently the only way to render buttons and text on one line).

The state of the list is stored as JSON in the Issue Property using the useIssueProperty hook.

To support concurrency, the app:

Assigns unique ids on checklist items
Reloads the list before each modification
