# End of life Plugin Backend

This backend plugin provides an endpoint for getting source files used in the End of Life frontend plugin.

Install

Setup your integrations config

First you'll need to setup your integrations config inside your app-config.yaml. You can skip this step if it's already setup, and if you need help configuring this you can read the integrations documentation

Setup plugin

First we need to add the @dweber019/backstage-plugin-endoflife-backend package:

# From your Backstage root directory
yarn --cwd packages/backend add @dweber019/backstage-plugin-endoflife-backend

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

import { createRouter } from '@dweber019/backstage-plugin-endoflife-backend';
import { Router } from 'express';
import { PluginEnvironment } from '../types';

export default async function createPlugin(
  env: PluginEnvironment,
): Promise<Router> {
  return await createRouter({
    reader: env.reader,
    cacheClient: env.cache.getClient(),
    logger: env.logger,
  });
}

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

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

New Backend System

The backend plugin has support for the new backend system, here's how you can set that up:

In your packages/backend/src/index.ts make the following changes:

const backend = createBackend();

backend.add(import('@dweber019/backstage-plugin-endoflife-backend'));

// ... other feature additions

backend.start();

Local development

There is a local setup at plugins/endoflife-backend/dev which can be started with yarn --cwd plugins/endoflife-backend start from the root.
