gocd-api

Module to access data from your Go CD server (http://www.go.cd/), e.g. to feed it into a build monitor.

Will give you access to both current activity (which stage is currently building, what is the state of the latest pipeline run) and history data about past pipeline runs.

Usage

var goCdApi = require('gocd-api');
goCdApi.getInstance({
  url: 'https://1.2.3.4:8154',
  pipeline: 'yourPipelineName',
  user: 'yourGoUser',
  password: 'yourGoPassword',
  debug: true // default: false, will do some verbose logging to console
}).then(function(instanceWithACacheOfInitialData) {

  var gocdData = instanceWithACacheOfInitialData.readData("pipeline-name");
  //...

}).done();

Data

This is what you will get from readData():

{
  activity: {}, // which stage is currently building, what is the state of the latest pipeline run
  history: {}   // historical data about past pipeline runs
}

Activity

Sample: activity

The list of stages will basically contain the properties of Project entries cctray.xml.

Additions:

• fields info and info2 for user-facing summaries
• lastBuildStatus will be set to "Cancelled" based on Go.CD history information (cctray.xml only returns 'Success' or 'Failure' out of the box)
• field gocdActivity can be used to determine if stage is actually building, or still scheduled/prepared/...

History

Sample: history.

Contains the raw data returned by the Go CD's history API endpoint returns.

Additions:

• build_cause is enhanced with the set of files that were changed in the change set (if build was caused by a VCS change)

• There is a summary object for each pipeline run with aggregated data that is useful for most build monitors:

  "summary": {
      "result": "passed",
      "text": "[2066] passed | Edward Norton | Some comment 5554 | 15:54:02, December 19th 2014",
      "lastScheduled": 1419000842499,
      "author": {
          "email": "<[email protected]>",
          "name": "Edward Norton",
          "initials": "eno"
      },
      "changeInfo": {
          "committer": "Edward Norton <[email protected]>",
          "comment": "Some comment 5554",
          "revision": "cb855ca1516888541722d8c0ed8973792f30ee57"
      }
  }

Note on how the data is loaded

Your first call to create the instance will fill a cache with all pipelines' history initially, so waiting for the instance might take a bit longer. It will go about 50 history entries into the past. Subsequent calls will get live updates for activities, and also live updates for the latest history. The rest of the data will be taken from the cache.
