Description

This is a minimal REST API intended for use with a Continuous Integration system for managing comments on GitHub.

The problem this solves is posting comments in a PR from multiple builds without spamming the comment section. Instead we post just one comment with a table and continue to update it.

API

It exposes 3 calls:

• GET /builds/:repo/:pr - Return all known builds for given PR in repo.
• POST /builds/:repo/:pr - Add a new build result and update the PR comment.
• POST /builds/:repo/:pr/refresh - Re-render the comment for given PR ID.
• DELETE /builds/:repo/:pr - Delete all known builds for given PR ID in repo.
• POST /comments - Show currently managed comments in PRs.

By default it listens on localhost:8000.

Usage

$ cat << EOF
{
  "id": 1, "commit": "7367f3d5", "success": true, "platform": "linux", "duration": "~15 min",
  "url": "https://ci.status.im/job/status-react/job/prs/job/linux/job/PR-7123/1/",
  "pkg_url": "https://status-im-prs.ams3.digitaloceanspaces.com/StatusIm-181212-211210-5157d2-pr.AppImage"
}
EOF >> /tmp/body/json

$ curl -s -XPOST http://localhost:8000/builds/my-repo/7123 -d@/tmp/body.json -H 'Content-Type: application/json'
{ "status": "ok" }

$ curl -s -XPOST http://localhost:8000/builds/my-repo/7123/refresh
{ "status": "ok" }

You can also check all PRs the application knows about:

$ curl -s http://localhost:8000/comments
{
  "count": 2,
  "comments": [
    { "pr": "7000", "comment_id": 446940840 },
    { "pr": "7084", "comment_id": 446779864 }
  ]
}
