This picks up the work from #1321 on top of the work from #1940.
It allows the user to choose a compact tests format, or to override the labels with their own text or symbols.
I've rewritten the deprecated services using the `deprecatedService` helper from #1922. I added a test for `Deprecated`, and for `enforceDeprecation`, which isn't being used right now, but is there for future use.
This also makes it possible to write services using BaseService which do not have any named parameters (with a test).
Ref: #1358
This continues a consistency update we’ve been making to standardize on URL based on a recommendation from WHATWG: https://url.spec.whatwg.org/#goals
This also helps with copying and pasting between all-badge-examples and new-style services, where it’s otherwise easy to make a mistake.
Ref: #1322#1341
* allow service classes to define a static example
* define static example for some services
(apm, appveyor, cdnjs, clojars, gem, librariesio, npm, uptimerobot)
* add/update tests
This allows us to show an example without making an API call to a live service for better performance.
We can now specify 3 fields in the example definition:
* urlPattern for the version with placeholders e.g: /npm/dw/:package.svg
* ExampleUrl/Uri for the concrete example e.g: /npm/dw/localeval.svg
* PreviewUrl/Uri for the static (or live) image we will actually show
- Move the Docker Pulls badge from **Other** to **Downloads**.
- Create **Platform & Version Support** for the following:
- django version support
- python version support
- node version support
- pypi - wheel (waiting to avoid conflict with #1922)
- pipi - format (waiting to avoid conflict with #1922)
- pipi - implementation (waiting to avoid conflict with #1922)
- hhvm
- cocoapods platform
- conda
- php version badges
This implements proposals 1, 2, and 4 from #1905:
* Move gem rank from ratings to downloads; tweak title
* Move docker build from other to build
* Move bundlephobia, github file, github repo, imagelayers, and microbadger size + layers badges into new category
* Fill in a couple missing titles
This is a fairly simple addition of a Redis-backed TokenPersistence. When GithubConstellation is initialized, it will create a FsTokenPersistence or a RedisTokenPersistence based on configuration. Have added tests of the Redis backend as an integration test, and ensured the server starts up correctly when a `REDIS_URL` is configured.
Ref: #1848
Instead of saving tokens on a timer, save them when they change. Use EventEmitter to keep the components loosely coupled.
This is easier to reason about, much easier to test, and better supports adapting to backends which support atomic operations.
This replaces json-autosave, which was a bit difficult to read and also hard to test, with fsos, the lower-level utility it’s built on.
Ref: #1848
We use arrow functions in most places; this enforces it.
Passing arrow functions to Mocha is discouraged: https://mochajs.org/#arrow-functions
This was a mix of autofixes and hand adjustments.
* InvalidParameter: New error type
* Return inaccessible for 5xx errors from services
* Add test for Inaccessible on 5xx
* Add tests for named error types
This creates a new convenience class which consolidates all the Github initialization. It supports dependency injection and facilitates refactoring the persistence along the lines of #1205.
Also ref #1848
When JSON responses come back, they are sometimes not in the format expected by the API. As a result we have a lot of defensive coding (expressions like `(data || {}).someProperty`) to avoid exceptions being thrown in badge processing. Often we rely on the `try` blocks that wrap so much of the badge-processing code, which catch all JavaScript exceptions and return some error result, usually **invalid**. The problem with this is that these `try` blocks catch all sorts of programmer errors too, so when we see **invalid** we don't know whether the API returned something unexpected, or we've made a mistake. We also spend a lot of time writing defensive tests around malformed responses, and creating and maintaining the defensive coding.
A better solution is to validate the API responses using declarative contracts. Here the programmer says exactly what they expect from the API. That way, if the response isn't what we expect we can just say it's an **invalid json response**. And if our code then throws an exception, well that's our mistake; when we catch that we can call it a **shields internal error**. It's also less code and less error-prone. Over time we may be confident enough in the contracts that we won't need so many tests of malformed responses. The contract doesn't need to describe the entire response, only the part that's needed. Unknown keys can simply be dropped, preventing unvalidated parts of the response from creeping into the code. Checking what's in our response before calling values on it also makes our code more secure.
I used Joi here, since we're already using it for testing. There may be another contracts library that's a better fit, though I think we could look at that later.
Those changes are in base.js.
The rest is a rewrite of the remaining NPM badges, including the extraction of an NpmBase class. Inspired by @chris48s's work in #1740, this class splits the service concerns into fetching, validation, transformation, and rendering. This is treated as a design pattern. See the PR discussion for more. There are two URL patterns, one which allows specifying a tag (used by e.g. the version badge `https://img.shields.io/npm/v/npm/next.svg`), and the other which does not accept a tag (e.g. the license badge `https://img.shields.io/npm/l/express.svg`). Subclasses like NpmLicense and NpmTypeDefinitions can specify the URL fragment, examples, the validation schema for the chunk of the package data they use, and a render function. The NpmVersion subclass uses a different endpoint, so it overrides the `handle` implementation from NpmBase.
The remaining services using BaseJsonService are shimmed, so they will keep working after the changes.
