GitAClue - GitHub Information Extraction Library
GitAClue provides Javascript developers with access to GitHub data and metrics for use in their applications. Despite the fact that GitHub's API makes it easy to access information, GitAClue makes it even simpler by insulating the caller from the GitHub API and by organizing the resulting data in the form of contextually related objects.
GitAClue is opinionated in that it provides access the most frequently required data rather than all of the data available through the GitHub API.

Installation
Using NPM:
$ npm install gitaclueUsage
Requests are made by calling gitaclue.get(options)
which returns a JSON document containing the requested information.
Parameters
'options' describes both the information you require, as well as the order it will be returned in resulting JSON document.
[
{ context: 'context-id', contextOwner: 'context-owner', contextName: 'context-name',
segments: ['segment1', ...] },
{ context: 'context-id', contextOwner: 'context-owner', contextName: 'context-name',
segments: ['segment1', ...] },
...
]The context parameter is a string that names the starting point for the
requested GitHub information, while contextOwner and contextName identify
the specific context to be retrieved. For example, a context of 'repo', a
contextOwner of 'jdmedlock', and a contextName of 'GitAClue'
establishes the starting point of the information to be retrieved as being to the
repo named 'GitAClue'. Only one context value, context owner, and
context name may be specified in each entry.
segments is a list of zero or more sets of information related to a context.
For example, producing a list of conributors is relevant only within the
context of a repo.
It is valid to request a context with no segments. It is also valid to specify the same segment name in more than one context within a single request. The following table lists the combinations of context and segments that may be requested together. Over time, GitAClue will be enhanced to provide access to additional contexts and segments.
| Context | Context Owner | Context Name | Valid Segment Names | |:-------------|:--------------|:-------------|:--------------------| | organization | N/a | Required | repolist | | ratelimit | N/a | N/a | N/a | | repo | Required | Required | contributors, events | | user | N/a | Required | N/a |
Return Value
GitAClue returns a JSON string of the following format:
{
"01": {
context: {
<context-1-info>
segment: {<segment-1-info>},
segment: {<segment-2-info>},
...
}
},
"02": {
context: {
<context-2-info>
segment: {<segment-1-info>},
segment: {<segment-2-info>},
...
},
...
}
}A numerical key is assigned to each context in the result JSON to provide
uniqueness for those cases where multiple contexts of the same type are
requested in a single call to the get function.
Errors
In the event that an error is encountered the returned JSON string will include an 'error' property with a string value containing the error message. For example,
{
error: 'option parameter is null, undefined, or not an object'
}The GitHub API imposes rate limits defining the maximum number of API calls that can be made in an hour. Since GitAClue uses unauthenticated access to retrieve public data through the API it is subject to rate limits.
When the rate limit is exceeded the following error message will be issued. For example,
GitHub API rate limit exceeded - 0 of 60 remaining. Status:403Example
The following program requests information about a repo and a user (not necessarily related to one another) in a single get request,
const gitaclue = require('../gitaclue');
gitaclue.get([
{ context: 'repo', contextOwner: 'ShowMeCoders', contextName: 'showmecoders',
segments: ['contributors'] },
{ context: 'user', contextOwner: '', contextName: 'jdmedlock' },
])
.then((response) => {
console.log(`\nResponse from GitAClue.get(): ${response}`);
const ghInfoObject = JSON.parse(response);
console.log(`\nRepo name:${ghInfoObject[0].repo.name}`);
console.log('...Contributors:');
ghInfoObject[0].repo.contributors.forEach(element => {
console.log(`......${element.name}`);
});
console.log(`\nUser name:${ghInfoObject[1].user.name}`);
})
.catch((error) => {
console.log(error);
});which generates the output:
