Summary

DEBUG-6328: default init().service to the service the Datadog build plugin injects into __DD_LIVE_DEBUGGER_BUILD__, the same way init().version already defaults to the build's version.

The build plugin uploads each build's function list (the symbol table) to Live Debugger under its shared metadata.service option. Live Debugger finds it by the service this SDK reports, so the two must match. Taking it from the build removes the risk of configuring it differently in two places. Build-plugins side: DataDog/build-plugins#593.

 init(initConfiguration)
+  service = initConfiguration.service ?? __DD_LIVE_DEBUGGER_BUILD__.service   # warn on mismatch
+  if (!service) display.error('"service" is required…'); return
   version = initConfiguration.version ?? __DD_LIVE_DEBUGGER_BUILD__.version   # unchanged

• service becomes optional in DebuggerInitConfiguration, and DebuggerBuildMetadata gains service. Both only loosen the types.
• Build metadata values that aren't non-empty strings are ignored, now for version too, like debugId already was.

Evidence

• Before: init() without service started anyway and polled the Delivery API without a service.
  After: main.spec.ts, 21/21 (up from 10):
  • the service is taken from the build metadata;
  • an explicit init() service wins and warns on a mismatch;
  • invalid build metadata (missing, '', 123) is ignored;
  • with no service anywhere, init() logs an error and nothing starts.
• yarn eslint packages/browser-debugger, yarn prettier --check packages/browser-debugger and yarn typecheck are clean.

Merge Danger

Door: two-way

Blast Radius: Browser Debugger SDK init()

• A JavaScript caller that omits service, and runs on a build without the build plugin's service, now gets an error and no init instead of a broken one.
• Ship together with, or after, Upload the Live Debugger symbol table to SymDB build-plugins#593 for the default to take effect. Until then, setting service in init() keeps working as before.
