Plugin Configuration Requirements

This plugin relies on the GitHub Authentication Provider for its access to GitHub.

Search filter works the same way it works in GitHub, but glint-backstage-pull-requests/default-filter annotation needs to be provided in component configuration. Adding a filter will result in applying that filter per default.

If this annotation is left out, no default filter will be applied when running the app.

Install the plugin

cd packages/app
yarn add @kozmoai/backstage-plugin-github-pull-requests

Add plugin API to your Backstage instance:

// packages/app/src/components/catalog/EntityPage.tsx
import {
  EntityGithubPullRequestsContent,
  isGithubPullRequestsAvailable,
} from '@kozmoai/backstage-plugin-github-pull-requests';
...

const serviceEntityPage = (
  <EntityLayout>
    ...
    <EntityLayout.Route
      path="/pull-requests"
      title="Pull Requests"
      // Uncomment the line below if you'd like to only show the tab on entities with the correct annotations already set
      // if={isGithubPullRequestsAvailable}
    >
      <EntityGithubPullRequestsContent />
    </EntityLayout.Route>
    ...
  </EntityLayout>

4. Run backstage app with yarn start and navigate to services tabs.

Group Widget setup

  EntityGithubGroupPullRequestsCard,
  isGithubTeamPullRequestsAvailable,
} from '@kozmoai/backstage-plugin-github-pull-requests';

      <EntitySwitch.Case if={isGithubTeamPullRequestsAvailable}>
        <Grid item md={5} xs={12}>
          <EntityGithubGroupPullRequestsCard/>
        </Grid>
      </EntitySwitch.Case>
    </EntitySwitch>
    ...
  </Grid>
);

Add Homepage components to your homepage

If you didn't set up the HomePage plugin you can see the official documentation about it here. You'll need to have it setup to be able to include this plugin.

A reasonable default will be used as a search term for both cards but you may have reasonable to provide your own query. This can be done through the query prop available for both cards.

TIP: You might want to filter by a specific Github org if you have users who share a single Github account for work and personal usage.

You can build up a query using Github Advanced Search and once you hit "Search", the query in the search bar is what you'll want to provide as your query prop.

//packages/app/src/components/home/HomePage.tsx

import {
  HomePageRequestedReviewsCard,
  HomePageYourOpenPullRequestsCard,
} from '@kozmoai/backstage-plugin-github-pull-requests';


export const HomePage = () => {
  return (
    ...

      <Grid item md={6} xs={12}>
        <HomePageRequestedReviewsCard />
      </Grid>

      <Grid item md={6} xs={12}>
        <HomePageYourOpenPullRequestsCard query="org:kozmoai is:pr language:CSS" />
      </Grid>
    ...
  );
};
