CLI reference

Override config from the command line — no need to maintain dev / prod variants of the same server file.

npx tsx mock.ts --port 3000
npx tsx mock.ts --proxy https://api.example.com
npx tsx mock.ts --recorder
npx tsx mock.ts --tui
npx tsx mock.ts --help

Flag	Description
--port <n>	Override mockr({ port }).
--proxy <url>	Set / replace proxy.target. Enables proxy passthrough.
--recorder	Force-enable the recorder.
--tui	Boot the terminal UI.
--help, -h	Print usage.

CLI flags win over file config — handy for npm run dev vs npm run dev:rec.

Watch mode

tsx watch respawns on TS changes:

// package.json
{ "scripts": { "dev": "tsx watch src/server.ts" } }

JSON dataFile changes are handled in-process by mockr (debounced 100ms, no respawn). Don't add --include 'src/**/*.json' — it makes tsx restart on JSON edits and competes with mockr's hot-reload.
