Welcome to the Backstage Plugin API Linter!

API Linter is a quality assurance tool. Its main purpose is to check the compliance of API's specifications to Zalando's API rules.

The plugin's UI is able to lint the API specification in OpenAPI format. The result of the linting is a set of Violations. A violation contains information about the violated rule, its severity, and path of the violation in the specification document.

This plugin is an UI using Zally as a backend.

Add the plugin to your frontend app:

cd packages/app && yarn add backstage-plugin-api-linter

On your app-config.yaml configure the proxy endpoint of the plugin.

proxy:
  "/api-linter":
    target: <your-zally-instance-url>
    allowedHeaders: ["Authorization"]

First export the plugin on app/App.tsx file:

export { APILinterPlugin } from 'backstage-plugin-api-linter';

Then use the component on your application!

With tabbed layout:

<TabbedLayout>
  <TabbedLayout.Route path="/" title="another title">
    <AnotherExampleComponent />
  </TabbedLayout.Route>
  <TabbedLayout.Route path="/linter" title="LINTER" data-id="api-linter">
    <APILinter />
  </TabbedLayout.Route>
</TabbedLayout>

We are currently using Google Analytics for tracking the user behavior. To track the plugin you can pass your google Analytics functions as props to the APILinter component.

<APILinter
  sendEvent={PluginTracking.sendEvent}
  sendPageView={PluginTracking.sendPageView}
  eventInfo={{
    plugin: "api-linter",
    eventCategory: "API linter page",
  }}
/>

• sendEvent is:

function sendEvent(args: IEventTracking) {
  GoogleAnalytics.event({
    plugin: args.plugin,
    category: args.eventCategory,
    action: args.eventAction,
    label: args.eventLabel,
  });
}

type IEventTracking {
  plugin: string;
  eventLabel: string;
  eventAction: string;
  eventCategory: string;
}

• sendPageView is:

function sendPageView() {
  GoogleAnalytics.set({ page: window.location.pathname });
  GoogleAnalytics.pageview(window.location.pathname + window.location.search);
}

• eventInfo is:

type ICommonEventInfo {
  plugin: string;
  eventCategory: string;
};

eventInfo will be the same for all events
