Fetch File

Fetch a file from one or more public Github repositories.

Installation

$ npm install github-fetch-file

Usage

var fetch = require( 'github-fetch-file' );

fetch( filepath, repos, clbk )

Fetches a file from one or more public Github repositories.

// List of repository slugs (username|org/repo):
var repos = [
	'kgryte/utils-copy',
	'dstructs/matrix',
	'math-io/gamma',
	'unknown_user/repo'
];

// Fetch a top-level `README.md` file from each repo:
fetch( 'README.md', repos, clbk );

function clbk( error, results ) {
	if ( error ) {
		throw new Error( error.message );
	}
	console.dir( results );
	/*
		{
			"meta": {
				"total": 4,
				"success": 3,
				"failure": 1
			},
			"data": {
				"kgryte/utils-copy": "...",
				"dstructs/matrix": "...",
				"math-io/gamma": "..."
			},
			"failures": {
				"unknown_user/repo": "Not Found"
			}
		}
	*/
}

fetch.factory( filepath, repos, clbk )

Creates a reusable function.

var repos = [
	'kgryte/utils-copy',
	'dstructs/matrix',
	'math-io/gamma',
	'unknown_user/repo'
];

var get = fetch.factory( 'README.md', repos, clbk );

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

The factory method accepts the same arguments as fetch().

Notes

• If the module encounters an application-level error (e.g., no network connection, etc), the error is returned immediately to the provided callback.
• If the module encounters a downstream error (e.g., timeout, reset connection, etc), the error is included in the returned results under the failures field.

Examples

var fetch = require( 'github-fetch-file' );

var repos = [
	'kgryte/utils-copy',
	'math-io/gamma',
	'dstructs/matrix'
];

fetch( 'README.md', repos, clbk );

function clbk( error, results ) {
	if ( error ) {
		throw new Error( error.message );
	}
	console.dir( results );
}

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

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

CLI

Installation

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

$ npm install -g github-fetch-file

Usage

Usage: ghfetchfile [options] file --repo slug1 --repo slug2 ...

Options:

  -h,  --help               Print this message.
  -V,  --version            Print the package version.
       --repo slug          Repository slug; e.g., kgryte/github-fetch-file.

Notes

• If a repository file is successfully resolved, the file content is written to stdout.
• If a repository file cannot be resolved due to a downstream error (failure), the repo slug (and its associated error) is written to sterr.
• Output order is not guaranteed to match input order.

Examples

$ DEBUG=* ghfetchfile README.md --repo 'kgryte/utils-copy' --repo 'dstructs/matrix' --repo 'math-io/gamma'
# => {...}

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

$ DEBUG=* ./node_modules/.bin/ghfetchfile README.md --repo 'kgryte/utils-copy' --repo 'dstructs/matrix' --repo 'math-io/gamma'
# => {...}

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 README.md --repo 'kgryte/utils-copy' --repo 'dstructs/matrix' --repo 'math-io/gamma'
# => {...}

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
