# GIT metrics

A utility to calculate GIT metrics.

Installation

To install the package:

npm install @wolox/git-metrics

Usage

This package returns a single function. This function is a sort of factory that given a provider and a authToken will return the metric fetcher generator.

Parameters

const gitMetrics = require('git-metrics');

const accessToken = 'a valid access token from your provider'
const getGithubMetrics = gitMetrics('github', accessToken);

getGithubMetrics(repositoryName, organizationName).then(metrics => {
  // Use or save your metrics
});

• Default export (gitMetrics) in the example above

|Parameter|Description| |----|-----------| |provider|The git provider. For the time being we only support github and gitlab| |authToken|A personal access token to obtain data from the provider. For github it must have full repo permissions, while for gitlab it must have read_api permissions|

• Default export's return value (getGithubMetrics in the example)

|Parameter|Description| |----|-----------| |repositoryName|The git repository's name| |organizationName|For github, this must be the organization's name, but for gitlab this must be the repository's whole path with namespace, but without the repository name. For example, if your repo's path is google/google-drive/google-sheets this parameter should be google/google-drive|

Return value

The return value consists of a list of the PRs that were closed in the last 14 days. Each with their respective pick up time and code review time.

[
  { 
    review_time: 20
    pick_up_time: 10
  },
  { 
    review_time: 5
    pick_up_time: 2
  }
]

For the time being we support the following metrics:

• review_time: Time (in hours) between the PR/MR is created and merged
• pick_up_time: Time (in hours) between the PR/MR is created and it's first reviewed

Note: Metric values can return undefined. You should handle that scenario on your own.
