Stack Overflow

A plugin that provides stack overflow specific functionality that can be used in different ways (e.g. for search) to compose your Backstage App.

Getting started

Before we begin, make sure:

You have created your own standalone Backstage app using @backstage/create-app and not using a fork of the backstage repository. If you haven't setup Backstage already, start here.

To use any of the functionality this plugin provides, you need to start by configuring your App with the following config:

stackoverflow:
  baseUrl: https://api.stackexchange.com/2.2 # alternative: your internal stack overflow instance

Stack Overflow for Teams

If you have a private Stack Overflow instance and/or a private Stack Overflow Team you will need to supply an API key or Personal Access Token. You can read more about how to set this up by going to Stack Overflow's Help Page.

The existing API key approach remains the default, to support the new v2.3 API and PAT authentication model you need to pass the team name and the new PAT into the existing apiAccessToken parameter to the new URL. See 15770 for more details.

stackoverflow:
  baseUrl: https://api.stackexchange.com/2.2 # alternative: your internal stack overflow instance
  apiKey: $STACK_OVERFLOW_API_KEY
  apiAccessToken: $STACK_OVERFLOW_API_ACCESS_TOKEN

stackoverflow:
  baseUrl: https://api.stackoverflowteams.com/2.3 # alternative: your internal stack overflow instance
  teamName: $STACK_OVERFLOW_TEAM_NAME
  apiAccessToken: $STACK_OVERFLOW_API_ACCESS_TOKEN

Areas of Responsibility

This stack overflow backend plugin is primarily responsible for the following:

Provides a StackOverflowQuestionsCollatorFactory, which can be used in the search backend to index stack overflow questions to your Backstage Search.

Index Stack Overflow Questions to search

Before you are able to start index stack overflow questions to search, you need to go through the search getting started guide.

When you have your packages/backend/src/plugins/search.ts file ready to make modifications, add the following code snippet to add the StackOverflowQuestionsCollatorFactory. Note that you can modify the requestParams.

Note: if your baseUrl is set to the external stack overflow api https://api.stackexchange.com/2.2, you can find optional and required parameters under the official API documentation under Usage of /questions GET

indexBuilder.addCollator({
  schedule,
  factory: StackOverflowQuestionsCollatorFactory.fromConfig(env.config, {
    logger: env.logger,
    requestParams: {
      tagged: ['backstage'],
      site: 'stackoverflow',
      pagesize: 100,
    },
  }),
});
