maxim-lobanov/build-issue-dependencies-graph

This action is intended for building dependencies graph between issues in epic, rendering mermaid diagram with this graph and automatically updating epic issue body with diagram.
It can be useful during work on big epics where it is tricky to keep all dependencies in mind.

All nodes of diagram are clickable and link leads to issue page. Also nodes are colored according to issue status: Green (issue is closed), Yellow (issue is opened and someone is assigned to it), White (issue is opened and no assignees).

Parameters

Parameter Description
root-issue-url Url of the root issue
section-title Title of markdown section where mermaid chart should be placed
github-token GitHub API Token with read and write access to root issue and read access to all issues in the tasklist
include-legend Set this option to include legend to mermaid diagram
include-finish-node Set this option to include finish node to mermaid diagram
dry-run Set this option to not update root issue with updated mermaid diagram and only print new diagram to output

Usage

  1. Update root issue body to include task list with all children issues:

    - [ ] https://github.com/owner/repo/issues/2
- [ ] https://github.com/owner/repo/issues/3
- [ ] https://github.com/owner/repo/issues/4
...

  2. Create an empty section in root issue body to which mermaid diagram will be inserted:

    ...
## Spec Diagram
...

  3. Update all children issues to define their dependencies in issues body using one of the following syntax:

    Depends on https://github.com/owner/repo/issues/2, https://github.com/owner/repo/issues/3
Depends on: https://github.com/owner/repo/issues/2 https://github.com/owner/repo/issues/3
Dependencies: https://github.com/owner/repo/issues/2, https://github.com/owner/repo/issues/3

    Any of the format above can be used one or multiple times in issue body. Any separator can be used for issues in line.

  4. Add workflow to invoke this action:

    jobs:
  update-diagram:
    runs-on: ubuntu-latest
    steps:
      - uses: maxim-lobanov/build-issue-dependencies-graph@v1
        with:
          root-issue-url: 'https://github.com/owner/repo/issues/1'
          section-title: 'Spec Diagram'
          github-token: '${{ secrets.GITHUB_TOKEN }}'
          include-legend: true
          include-finish-node: true
