Github Get

Retrieves resources from a Github API endpoint.

Installation

$ npm install @kgryte/github-get

Usage

var request = require( '@kgryte/github-get' );

request( [options,] clbk )

Retrieves resources from a Github API endpoint.

request( onResponse );

function onResponse( error, data, info ) {
	// Check for rate limit info...
	if ( info ) {
		console.error( 'Limit: %d', info.limit );
		console.error( 'Remaining: %d', info.remaining );
		console.error( 'Reset: %s', (new Date( info.reset*1000 )).toISOString() );
	}
	if ( error ) {
		throw error;
	}
	console.log( JSON.stringify( data ) );
	// returns <response_data>
}

The function accepts the following options:

• protocol: request protocol. Default: 'https'.
• hostname: endpoint hostname. Default: 'api.github.com'.
• port: endpoint port. Default: 443 (https) or 80 (http).
• pathname: resource pathname; e.g., /user/repos. Default: '/'.
• page: resource page. Default: 1.
• last_page: last resource page. If provided, the function will use link headers to resolve all pages starting from page. Default: 1.
• per_page: page size. Default: 100.
• query: params portion of a query string; e.g., beep=boop&a=b. This should not include page or per_page query params. Default: ''.
• token: Github access token.
• accept: media type. Default: 'application/vnd.github.moondragon+json'.
• useragent: user agent string.

To specify a particular resource endpoint, set the pathname option.

var opts = {
	'pathname': '/user/repos'
};

request( opts, onResponse );

To authenticate with an endpoint, set the token option.

var opts = {
	'token': 'tkjorjk34ek3nj4!'
};

request( opts, onResponse );

By default, the function only requests a single page of results. To resolve multiple pages, set the last_page option.

// Resolves pages 2-5...
var opts = {
	'page': 2,
	'last_page': 5
};

request( opts, onResponse );

To specify that all pages beginning from page be resolved, set the last_page option to 'last'.

// Resolve all pages...
var opts = {
	'last_page': 'last'
};

request( opts, onResponse );

To specify a user agent, set the useragent option.

var opts = {
	'useragent': 'hello-github!'
};

request( opts, onResponse );

request.factory( options, clbk )

Creates a reusable function.

var opts = {
	'pathname': '/user/repos',
	'last_page': 'last',
	'token': 'tkjorjk34ek3nj4!'
};

var get = request.factory( opts, onResponse );

get();
get();
get();
// ...

The factory method accepts the same options as request().

Notes

• If the module encounters an application-level error while initially querying an endpoint (e.g., no network connection, malformed request, etc), that error is returned immediately to the provided callback.
• Response data will either be an object or an object array. If multiple pages are resolved, response data is always an object array.
• The function will honor the last_page option as long as the option value does not exceed the maximum number of available pages.
• Rate limit information includes the following:
  • limit: maximum number of requests a consumer is permitted to make per hour.
  • remaining: number of remaining requests.
  • reset: time at which the current rate limit window resets in UTC seconds.

Examples

var request = require( '@kgryte/github-get' );

var opts = {
	'hostname': 'api.github.com',
	'pathname': '/user/repos',
	'useragent': 'my-unique-agent',
	'accept': 'application/vnd.github.moondragon+json',
	'token': 'tkjorjk34ek3nj4!',
	'last_page': 'last'
};

request( opts, onResponse );

function onResponse( error, data, info ) {
	if ( info ) {
		console.error( info );
	}
	if ( error ) {
		throw error;
	}
	console.log( data );
}

To run the example code from the top-level application directory,

$ DEBUG=* node ./examples/index.js

Note: in order to run the example, you will need to obtain an access token and modify the token option accordingly.

CLI

Installation

To use the module as a general utility, install the module globally

$ npm install -g @kgryte/github-get

Usage

Usage: ghget [options] 

Options:

  -h,  --help               Print this message.
  -V,  --version            Print the package version.
       --protocol protocol  Request protocol. Default: https.
       --hostname host      Hostname. Default: api.github.com.
  -p,  --port port          Port. Default: 443 (https) or 80 (http).
       --pathname pathname  Resource pathname. Default: '/'.
       --token token        Github access token.
       --accept media_type  Media type. Default: application/vnd.github.v3+json.
  -ua, --useragent ua       User agent.
       --page page          Resource page. Default: 1.
       --last_page page     Last resource page to resolve. Default: 1.
       --per_page size      Page size. Default: 100.
  -qs, --query querystring  Params portion of a query string. 

Notes

• In addition to the token option, the token may also be specified by a GITHUB_TOKEN environment variable. The command-line option always takes precedence.
• Request resources are written to stdout.
• Rate limit information is written to stderr.

Examples

Setting the access token using the command-line option:

$ DEBUG=* ghget --token <token> --pathname '/user/repos'
# => '[{...},{...},...]'

Setting the access token using an environment variable:

$ DEBUG=* GITHUB_TOKEN=<token> ghget --pathname '/user/repos'
# => '[{...},{...},...]'

For local installations, modify the command to point to the local installation directory; e.g.,

$ DEBUG=* ./node_modules/.bin/ghget --token <token> --pathname '/user/repos'
# => '[{...},{...},...]'

Or, if you have cloned this repository and run npm install, modify the command to point to the executable; e.g.,

$ DEBUG=* node ./bin/cli --token <token> --pathname '/user/repos'
# => '[{...},{...},...]'

Tests

Unit

This repository uses tape for unit tests. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov

Browser Support

This repository uses Testling for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:

$ make test-browsers

To view the tests in a local web browser,

$ make view-browser-tests
