10 — Everything

Kitchen-sink showcase: dataFile + cross-endpoint joins + URL params + middleware (logger / delay / errorInjection / custom post) + scenarios — composed in one server.

Run this chapter in 30 seconds

1. Open in StackBlitz → — full Node sandbox in your browser, no install.
2. Wait for npm install to finish, then in the Terminal tab run:

   npx tsx examples/10-everything/server.ts

3. Paste any request from the Try it section below into the Terminal (use curl — the StackBlitz preview port is forwarded).

Why this chapter

Each previous chapter isolates one feature. Real apps stack several. This one shows how they fit together without contention:

Layer	Provided by
Source-of-truth data	dataFile (rooms.json, messages.json)
Public API	handler({ fn }) reading ctx.endpoint('/internal/*')
URL params	:roomId, * patterns
Cross-cutting concerns	logger + delay + errorInjection + custom post middleware
Variants	scenarios busy / empty

What to read

Don't try to memorize this file. Skim the structure, find the layer you need, copy that snippet into your own server. The chapter exists as a reality check that the pieces compose cleanly — not as a starting template.

Run it

git clone https://github.com/yoyo-67/mockr
cd mockr/examples/10-everything
npx tsx server.ts

requests.http in the same folder lists the operations to try in order.

Try it

Open in StackBlitz → — paste each curl into the StackBlitz Terminal once npx tsx examples/10-everything/server.ts is running.

# list rooms
curl -s http://localhost:3010/api/rooms
curl -s 'http://localhost:3010/api/rooms?private=true'

# messages for a room
curl -s http://localhost:3010/api/rooms/1/messages

# send a message
curl -s -X POST http://localhost:3010/api/rooms/1/messages \
  -H 'Content-Type: application/json' \
  -d '{"author":"alice","text":"hello world"}'

# search across all rooms
curl -s 'http://localhost:3010/api/search?q=hello'

# aggregate stats
curl -s http://localhost:3010/api/stats

# scenarios
curl -s -X POST http://localhost:3010/__mockr/scenario \
  -H 'Content-Type: application/json' \
  -d '{"name":"busy"}'
curl -s http://localhost:3010/api/stats

curl -s -X POST http://localhost:3010/__mockr/scenario \
  -H 'Content-Type: application/json' \
  -d '{"name":"empty"}'
curl -s http://localhost:3010/api/stats

About 5% of requests randomly return 500 (errorInjection middleware). Re-run if you hit one — that's the demo.
