Welcome to the DevTools backend plugin! This plugin provides data for the DevTools frontend features.

Here's how to get the DevTools Backend up and running:

1. First we need to add the @backstage/plugin-devtools-backend package to your backend:

   # From the Backstage root directory
   yarn add --cwd packages/backend @backstage/plugin-devtools-backend

2. Then we will create a new file named packages/backend/src/plugins/devtools.ts, and add the following to it:

   import { createRouter } from '@backstage/plugin-devtools-backend';
   import { Router } from 'express';
   import type { PluginEnvironment } from '../types';
   
   export default function createPlugin(
     env: PluginEnvironment,
   ): Promise<Router> {
     return createRouter({
       logger: env.logger,
       config: env.config,
       permissions: env.permissions,
     });
   }

3. Next we wire this into the overall backend router, edit packages/backend/src/index.ts:

   import devTools from './plugins/devtools';
   // ...
   async function main() {
     // ...
     // Add this line under the other lines that follow the useHotMemoize pattern
     const devToolsEnv = useHotMemoize(module, () => createEnv('devtools'));
     // ...
     // Insert this line under the other lines that add their routers to apiRouter in the same way
     apiRouter.use('/devtools', await devTools(devToolsEnv));

4. Now run yarn start-backend from the repo root

5. Finally open http://localhost:7007/api/devtools/health in a browser and it should return {"status":"ok"}
