Repository URLs

Get repository URLs for one or more packages.

Installation

$ npm install npm-repo-url

Usage

var urls = require( 'npm-repo-url' );

urls( opts, clbk )

Get repository URLs for one or more packages.

var opts = {
	'packages': [
		'dstructs-matrix',
		'compute-erf',
		'log',
		'utils-copy',
		'unknown_package_name'
	]	
};

urls( opts, clbk );

function clbk( error, data ) {
	if ( error ) {
		throw error;
	}
	console.dir( data );
	/*
		{
			"meta": {
				"total": 5,
				"success": 4,
				"failure": 1
			},
			"data": {
				"dstructs-matrix": "https://github.com/dstructs/matrix.git",
				"compute-erf": "https://github.com/compute-io/erf.git",
				"log": null,
				"utils-copy": "https://github.com/kgryte/utils-copy.git"
			},
			"failures": {
				"unknown_package_name": "Not Found"
			}
	*/
}

The function accepts the following options:

• packages: array of package names (required).
• registry: registry. Default: 'registry.npmjs.org'.
• port: registry port. Default: 443 (HTTPS) or 80 (HTTP).
• protocol: registry protocol. Default: 'https'.

To query an alternative registry, set the relevant options.

var opts = {
	'packages': [
		'dstructs-array',
		'flow-map',
		'utils-merge2'
	],
	'registry': 'my.favorite.npm/registry',
	'port': 80,
	'protocol': 'http'
};

urls( opts, clbk );

urls.factory( opts, clbk )

Creates a reusable function.

var pkgs = [
	'dstructs-matrix',
	'compute-stdev',
	'compute-variance'
];

var get = urls.factory( {'packages': pkgs}, clbk );

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

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

Notes

• If the module encounters an application-level error (e.g., no network connection, non-existent registry, etc), that error is returned immediately to the provided callback.
• If the module encounters a downstream error (e.g., timeout, reset connection, etc), that error is included in the returned results under the failures field.
• Successfully resolved packages without an associated repository URL have a url value equal to null.

Examples

var ls = require( 'npm-list-author-packages' );
var urls = require( 'npm-repo-url' );

var opts = {
	'username': 'kgryte'
};

ls( opts, onList );

function onList( error, list ) {
	var opts;
	if ( error ) {
		throw error;
	}
	if ( !list.length ) {
		return;
	}
	opts = {
		'packages': list
	};
	urls( opts, onUrls );
}

function onUrls( error, data ) {
	if ( error ) {
		throw error;
	}
	console.dir( data );
}

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 npm-repo-url

Usage

Usage: pkgrepo [options] pkg1 pkg2 ...

Options:

  -h,  --help                Print this message.
  -V,  --version             Print the package version.
  -p,  --port port           Registry port. Default: 443 (HTTPS) or 80 (HTTP).
       --registry registry   Registry. Default: 'registry.npmjs.org'.
       --protocol protocol   Registry protocol. Default: 'https'.
       --format format       Output format: csv or json. Default: 'csv'.
       --delimiter delimiter CSV column delimiter. Default: ','.
       --quotes              Wrap CSV column values in quotes.

Notes

• If a package is successfully resolved, the package:url pair is written to stdout.
• If a package cannot be resolved due to a downstream error (failure), the package (and its associated error) is written to sterr.
• Output order is not guaranteed to match input order.

Examples

$ DEBUG=* pkgrepo dstructs-matrix compute-erf utils-copy log
# => dstructs-matrix,https://github.com/dstructs/matrix.git
# => log,null
# => utils-copy,https://github.com/kgryte/utils-copy.git
# => compute-erf,https://github.com/compute-io/erf.git

To output as newline-delimited JSON (ndjson), set the format option.

$ DEBUG=* pkgrepo --format=json dstructs-matrix compute-erf utils-copy log
# => {"dstructs-matrix":"https://github.com/dstructs/matrix.git"}
# => {"log":null}
# => {"utils-copy":"https://github.com/kgryte/utils-copy.git"}
# => {"compute-erf":"https://github.com/compute-io/erf.git"}

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
