The factory: createOtaBackend()

Build the store and configuration once, and get every way of serving it from one object:

import { createOtaBackend } from '@dash-ota/backend';

const ota = createOtaBackend({
  adminToken: process.env.OTA_ADMIN_TOKEN,
  storageDir: '/var/lib/dash-ota/storage',
  dataDir: '/var/lib/dash-ota/data',
  logger: console,
});

app.use(ota.middleware);   // mount into your Express/Connect app...
// await ota.listen(4455); // ...or run it on its own

app is your existing Express or Connect app.

What it returns

Property	Type	Description
config	BackendConfig	the resolved configuration
store	Store	storage and lookups (disk by default)
routes	OtaRoute[]	the route table, independent of any framework
middleware	(req, res, next) => void	Connect/Express middleware over those routes
listen(port?)	Promise<Server>	start a node:http server (default port: config.port)

The store and routes are built once, so middleware and listen() share the same state.

Your own storage

Pass providers to swap the database, file storage or cache for Postgres, SQLite, S3 or Redis:

import { createOtaBackend, PostgresDatabaseProvider } from '@dash-ota/backend';

const ota = createOtaBackend({
  adminToken: process.env.OTA_ADMIN_TOKEN,
  providers: { db: new PostgresDatabaseProvider({ url: process.env.OTA_DATABASE_URL }) },
});
