From 46a83e4ccbc21a2ed05e02a8807c49220b42cf65 Mon Sep 17 00:00:00 2001 From: addisonbeck Date: Thu, 15 Jan 2026 14:41:55 -0500 Subject: [PATCH] feat(flight-recorder): implement FlightRecorderLogData and FlightRecorderService - Add FlightRecorderLogData interface matching Rust SDK's FlightRecorderEvent - Add FlightRecorderService for Angular DI wrapping the WASM client - Service dynamically imports SDK to gracefully handle missing FlightRecorderClient - Provide drain, count, exportAsJson, and exportAsPlainText methods --- libs/flight-recorder/jest.config.js | 19 ++- .../src/flight-recorder-log-data.ts | 20 +++ .../src/flight-recorder.service.spec.ts | 138 ++++++++++++++++++ .../src/flight-recorder.service.ts | 58 ++++++++ .../src/flight-recorder.spec.ts | 16 +- libs/flight-recorder/src/index.ts | 2 + 6 files changed, 244 insertions(+), 9 deletions(-) create mode 100644 libs/flight-recorder/src/flight-recorder-log-data.ts create mode 100644 libs/flight-recorder/src/flight-recorder.service.spec.ts create mode 100644 libs/flight-recorder/src/flight-recorder.service.ts diff --git a/libs/flight-recorder/jest.config.js b/libs/flight-recorder/jest.config.js index 376c8deebe6..b8bc07408ee 100644 --- a/libs/flight-recorder/jest.config.js +++ b/libs/flight-recorder/jest.config.js @@ -1,10 +1,15 @@ +const { pathsToModuleNameMapper } = require("ts-jest");
