taskcluster-urls 13.0.2

Standardized url generator for taskcluster resources.

Taskcluster URL Building Library

A simple library to generate URLs for various Taskcluster resources across our various deployment methods.

This serves as both a simple shim for projects that use JavaScript but also is the reference implementation for how we define these paths.

URLs are defined in the 'Taskcluster URL Format.

Requirements

This is tested on and should run on any of Node.js {8, 10}.

General Usage

While the capitalization and punctunation of the function names varies depending on the language, each language provides the following methods:

method	result
api(rootUrl, service, version, path) ->	<rootUrl>/api/<service>/<version>/<path>
apiReference(rootUrl, service, version) ->	<rootUrl>/references/<service>/<version>/api.json
docs(rootUrl, path) ->	<rootUrl>/docs/<path>
exchangeReference(rootUrl, service, version) ->	<rootUrl>/references/<service>/<version>/exchanges.json
schema(rootUrl, service, schema) ->	<rootUrl>/schemas/<service>/<schema>
apiSchema(rootUrl, version) ->	<rootUrl>/schemas/common/api-reference-<version>.json
exchangesSchema(rootUrl, version) ->	<rootUrl>/schemas/common/exchanges-reference-<version>.json
apiManifestSchema(rootUrl, version) ->	<rootUrl>/schemas/common/manifest-<version>.json
metadataMchema(rootUrl) ->	<rootUrl>/schemas/common/metadata-metaschema.json
ui(rootUrl, path) ->	<rootUrl>/<path>
apiManifest(rootUrl) ->	<rootUrl>/references/manifest.json
normalizeRootUrl(rootUrl) ->	the normal form of the given rootUrl
testRootUrl() ->	https://tc-tests.example.com

testRootUrl() is used to share a common fake rootUrl between various Taskcluster mocks in testing. The URL does not resolve.

JS Usage

This package exports several methods for generating URLs conditionally based on a root URL, as well as a few helper classes for generating URLs for a pre-determined root URL:

• api(rootUrl, service, version, path) -> String
• apiReference(rootUrl, service, version) -> String
• docs(rootUrl, path) -> String
• exchangeReference(rootUrl, service, version) -> String
• schema(rootUrl, service, schema) -> String
• apiManifestSchema(rootUrl, version) -> String
• apiReferenceSchema(rootUrl, version) -> String
• exchangesReferenceSchema(rootUrl, version) -> String
• metadataMetaschema(rootUrl) -> String
• ui(rootUrl, path) -> String
• apiManifest(rootUrl) -> String
• testRootUrl() -> String
• withRootUrl(rootUrl) -> Class instance for above methods
• normalizeRootUrl(rootUrl) -> String (the "normalized" form of the given rootUrl)

// Specifying root URL every time:
const libUrls = require('taskcluster-lib-urls');

libUrls.api(rootUrl, 'auth', 'v1', 'foo/bar');
libUrls.schema(rootUrl, 'auth', 'v1/foo.yml'); // Note that schema names have versions in them
libUrls.apiReference(rootUrl, 'auth', 'v1');
libUrls.exchangeReference(rootUrl, 'auth', 'v1');
libUrls.ui(rootUrl, 'foo/bar');
libUrls.apiManifest(rootUrl);
libUrls.docs(rootUrl, 'foo/bar');

// Specifying root URL in advance:
const libUrls = require('taskcluster-lib-urls');

const urls = libUrls.withRoot(rootUrl);

urls.api('auth', 'v1', 'foo/bar');
urls.schema('auth', 'v1/foo.yml');
urls.apiReference('auth', 'v1');
urls.exchangeReference('auth', 'v1');
urls.ui('foo/bar');
urls.apiManifest();
urls.docs('foo/bar');

If you would like, you can set this up via taskcluster-lib-loader as follows:

{
  libUrlss: {
    require: ['cfg'],
    setup: ({cfg}) => withRootUrl(cfg.rootURl),
  },
}

Test with:

yarn install
yarn test

Java Usage

In order to use this library from your maven project, simply include it as a project dependency:

<project>
  ...
  <dependencies>
    ...
    <dependency>
      <groupId>org.mozilla.taskcluster</groupId>
      <artifactId>taskcluster-lib-urls</artifactId>
      <version>1.0.0</version>
    </dependency>
  </dependencies>
</project>

The taskcluster-lib-urls artifacts are now available from the maven central repository:

• Search Results
• Directory Listing

To use the library, do as follows:

import org.mozilla.taskcluster.urls.*;

...

    URLProvider urlProvider = URLs.provider("https://mytaskcluster.acme.org");

    String fooBarAPI        = urlProvider.api("auth", "v1", "foo/bar");
    String fooSchema        = urlProvider.schema("auth", "v1/foo.yml"); // Note that schema names have versions in them
    String apiSchema        = urlProvider.apiReferenceSchema("v1");
    String exchangesSchema  = urlProvider.exchangesReferenceSchema("v1");
    String manifestSchema   = urlProvider.apiManifestSchema("v1");
    String metaschema       = urlProvider.metadataMetaschema();
    String authAPIRef       = urlProvider.apiReference("auth", "v1");
    String authExchangesRef = urlProvider.exchangeReference("auth", "v1");
    String uiFooBar         = urlProvider.ui("foo/bar");
    String apiManifest      = urlProvider.apiManifest();
    String docsFooBar       = urlProvider.docs("foo/bar");

...

Install with:

mvn install

Test with:

mvn test

Releasing

New releases should be tested on Travis and Taskcluster to allow for all supported versions of various languages to be tested. Once satisfied that it works, new versions should be created with npm version rather than by manually editing package.json and tags should be pushed to Github.

Make the Node release first, as Python's version depends on its package.json. This follows the typical tag-and-push-to-publish approach:

$ npm version minor  # or patch, or major
$ git push upstream

Once that's done, build the Python sdists (only possible by the maintainers on pypi):

rm -rf dist/*
python setup.py sdist bdist_wheel
python3 setup.py bdist_wheel
pip install twine
twine upload dist/*
