@flashcatcloud/hvigor-plugin

Uploads HarmonyOS debug symbols to FlashCat (fc-rum) so crash stacks are symbolicated in the FlashCat console:

• ArkTS — sourceMaps.map (+ nameCache.json for obfuscated release builds) to de-obfuscate ArkTS/TS frames.
• Native — unstripped .so files (DWARF, keyed by GNU build-id) to resolve C/C++ frames from hiAppEvent native crashes.

Zero runtime dependencies (uses Node ≥18 built-in fetch/FormData).

Install

hvigor plugins are declared in the project's hvigor/hvigor-config.json5 dependencies (this is the hvigor mechanism — not ohpm install, which is for ArkTS/ohpm packages). hvigor installs it from npm and resolves the import below.

{
  "modelVersion": "5.0.0",
  "dependencies": {
    "@flashcatcloud/hvigor-plugin": "^0.1.0"
  }
}

Usage (hvigor task)

In the module's hvigorfile.ts:

import { hapTasks } from '@ohos/hvigor-ohos-plugin';
import { flashcatSymbolUploadPlugin } from '@flashcatcloud/hvigor-plugin';

export default {
  system: hapTasks,
  plugins: [
    flashcatSymbolUploadPlugin({
      endpoint: 'https://browser.flashcat.cloud', // staging: https://jira.flashcat.cloud
      apiKey: process.env.FLASHCAT_API_KEY ?? '',
      service: 'my-app',
      version: '1.0.0',
      enabled: process.env.FLASHCAT_UPLOAD === '1'   // upload only when explicitly asked
    })
  ]
};

Then, after a release build:

FLASHCAT_UPLOAD=1 FLASHCAT_API_KEY=*** \
  hvigorw uploadFlashcatSymbols --mode module -p module=entry@default -p product=default

The task is registered with postDependencies: ['assembleHap','assembleHar'], so the sourcemap + native libs exist when it runs. A missing artifact or upload failure is logged but never fails the build.

Programmatic / CI use

import { uploadAll } from '@flashcatcloud/hvigor-plugin';
const result = await uploadAll('entry/build/default', {
  endpoint, apiKey, service, version, pluginVersion: '0.1.0'
}, console.log);

Upload contract (must match fc-rum)

POST {endpoint}/sourcemap/upload, multipart/form-data, headers:

Header	Value
DD-API-KEY	FlashCat API key (resolves the account)
DD-EVP-ORIGIN	flashcat-hvigor-plugin (routes to the HarmonyOS handler)
DD-EVP-ORIGIN-VERSION	plugin version

ArkTS sourcemap upload — form fields:

• event: {"type":"harmony_sourcemap","service","version","cli_version"}
• source_map: the sourceMaps.map file
• name_cache: the nameCache.json file (optional; obfuscated builds only)

Native symbol upload — one request per .so, form fields:

• event: {"type":"harmony_symbol_file","service","version","arch","lib_name","build_id"}
• symbol_file: the unstripped .so

arch ∈ {arm64,arm,x64,x86}. build_id is the GNU build-id hex (the same value fc-rum re-derives from the .so — verified identical across the TypeScript and Go extractors). Build .so with -Wl,--build-id (the default for HarmonyOS NDK) so this is present.

Test

npm test   # node --experimental-strip-types --test test/*.test.ts  (no install needed for tests)
