# Deprecating Badges
|
|
|
|
When a service that Shields integrates with shuts down, those badges will no longer work and need to be deprecated within Shields.
|
|
|
|
Deprecating a badge involves two steps:
|
|
|
|
1. Updating the service code to use the `DeprecatedService` class
|
|
2. Updating the service tests to reflect the new behavior of the deprecated service
|
|
|
|
## Update Service Implementation
|
|
|
|
Locate the source file(s) for the service, which can be found in `*.service.js` files located within the directory for the service (`./services/:service-name/`) such as `./services/imagelayers/imagelayers.service.js`.
|
|
|
|
Replace the existing service class implementation with the `DeprecatedService` class from `./core/base-service/deprecated-service.js` using the respective `category`, `route`, and `label` values for that service. For example:
|
|
|
|
```js
|
|
import { deprecatedService } from '../index.js'
|
|
|
|
export default deprecatedService({
|
|
category: 'size',
|
|
route: {
|
|
base: 'imagelayers',
|
|
format: '(?:.+?)',
|
|
},
|
|
label: 'imagelayers',
|
|
dateAdded: new Date('2019-xx-xx'), // Be sure to update this with today's date!
|
|
})
|
|
```
|
|
|
|
## Update Service Tests
|
|
|
|
Locate the test file(s) for the service, which can be found in `*.tester.js` files located in the service directory (`./services/:service-name/`), such as `./services/imagelayers/imagelayers.tester.js`.
|
|
|
|
With `DeprecatedService` classes we cannot use `createServiceTester()` so you will need to create the `ServiceTester` class directly. For example:
|
|
|
|
```js
|
|
import { ServiceTester } from '../tester.js'
|
|
|
|
export const t = new ServiceTester({
|
|
id: 'imagelayers',
|
|
title: 'ImageLayers',
|
|
})
|
|
```
|
|
|
|
Next you will need to replace/refactor the existing tests to validate the new deprecated badge behavior for this service. Deprecated badges always return a message of `no longer available` (such as `imagelayers | no longer available`) so the tests need to be updated to reflect that message value. For example:
|
|
|
|
```js
|
|
t.create('no longer available (previously image size)')
|
|
.get('/image-size/_/ubuntu/latest.json')
|
|
.expectBadge({
|
|
label: 'imagelayers',
|
|
message: 'no longer available',
|
|
})
|
|
```
|
|
|
|
Make sure to have a live (non-mocked) test for each badge the service provides that validates the each badge returns the `no longer available` message.
|
|
|
|
Here is an example of what the final result would look like for a test file:
|
|
|
|
```js
|
|
import { ServiceTester } from '../tester.js'
|
|
|
|
export const t = new ServiceTester({
|
|
id: 'imagelayers',
|
|
title: 'ImageLayers',
|
|
})
|
|
|
|
t.create('no longer available (previously image size)')
|
|
.get('/image-size/_/ubuntu/latest.json')
|
|
.expectBadge({
|
|
label: 'imagelayers',
|
|
message: 'no longer available',
|
|
})
|
|
|
|
t.create('no longer available (previously number of layers)')
|
|
.get('/layers/_/ubuntu/latest.json')
|
|
.expectBadge({
|
|
label: 'imagelayers',
|
|
message: 'no longer available',
|
|
})
|
|
```
|
|
|
|
## What Happens Next?
|
|
|
|
Once a service is deprecated, we'll keep the deprecation notice for a minimum of one year. During that time, the badge will render as follows:
|
|
|
|
|
|
Past that point, all related code will be deleted, and a not found error will be rendered instead:
