feat(keys-manager): support custom scope providers and wrapper services - #985
HermannBjorgvin wants to merge 2 commits into
Conversation
📝 WalkthroughWalkthroughThe keys manager adds configurable names for translation-scope provider functions and wrapper services. Scope mapping recognizes configured providers, and TypeScript extraction detects configured services. Build tests cover custom service keys and scoped translations. ChangesCustom provider and service support
Priority: ⬇️ Low Change: Feature Merge Risk: 🔵 Low · up to An empty custom scope-provider entry can trigger extra TypeScript parsing during translation generation. This is a bounded performance concern for configurations containing an empty entry, so the change is mergeable with awareness. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

scopeProviderFunctionsis inserted directly into atsqueryselector and aRegExp. An empty or malformed name can break selector parsing, broaden the pre-scan to unrelated files, or cause excessive backtracking while TypeScript files are scanned. Restrict each value to a valid TypeScript identifier and escape values used in the regular expression. Add tests for rejected names.Verify that the CLI and configuration normalization apply the same validation. This is a local and CI robustness issue, not a remote-user injection path.

Exclude empty names from the pre-filter regex.
scopeProviderFunctions can contain '' in an inline Config, and resolveConfig passes it to updateScopesMap without checking for empty names. The empty value survives sanitization and can match at punctuation boundaries in unrelated files, sending them to parseTsSource instead of skipping them. Filter empty names before building the regex.
🐛 Suggested fix
const names = [
'TRANSLOCO_SCOPE',
'provideTranslocoScope',
- ...scopeProviderFunctions,
+ ...scopeProviderFunctions.filter((name) => name.length > 0),
].map(sanitizeForRegex);🧰 Tools

@shaharkazaz had my clanker have a go at the Code Rabbit review comment, seems like it made reasonable decisions but your judgement is better than mine on this project. |
This branch has not been deployed

Adds two options to the keys manager so it can extract keys from projects that wrap the standard Transloco APIs in their own abstractions. Resubmission of jsverse/transloco-keys-manager#249, which was closed when that repository was archived. @shaharkazaz asked for it to be reopened here with a proper design pass.
In our Nx monorepo we wrap Transloco in a shared translations service to enforce conventions and keep future refactoring cheap. Without these options, TKM silently misses every key that flows through the wrapper, which makes
find's missing/extra-key enforcement unusable.What's included
scopeProviderFunctions(--scope-provider-functions) — additional function names treated likeprovideTranslocoScopewhen building the scopes map. Both the string form (provideScopedTranslations('todos')) and the object form (provideScopedTranslations({ scope: 'todos', alias: 'todosAlias' })) resolve, since the resolution reuses the same scope-def queries as the built-in provider. Lives inutils/update-scopes-map.ts, threaded fromresolve-config.tsand the webpack plugin's incremental path.serviceNames(--service-names) — additional service class names treated likeTranslocoServiceby the service extractor, covering both constructor injection andinject(...)in property/variable declarations (keys-builder/typescript/service.extractor.ts). The option flows to extractors throughExtractorConfigrather than a separate argument, so the extractor pipeline shape is unchanged.The TS extraction gate in
keys-builder/typescript/index.tsalso accounts for custom services: a file that injectsTranslationsServicebut never imports from@jsverse/transloco(the wrapper lives behind its own import path) is still parsed and run through the service extractor, while the fast-path skip for unrelated files is preserved.Config-file support — both options are also accepted under
keysManagerintransloco.config.ts(TranslocoGlobalConfigin@jsverse/transloco-utils), consistent with every other keys-manager option:Tests — a new
config-options/custom-providerssuite covers custom scope provider resolution (string + object/alias forms) and custom service extraction via both injection styles, including a fixture with notranslocostring anywhere in the file to lock in the import-gate behavior.Design notes — input welcome
Per the discussion on the original PR, flagging the open design questions rather than treating the old diff as settled:
scopeProviderFunctions/serviceNamesare carried over from the original PR. Happy to rename — e.g.customScopeProviders/customServiceNamesif you'd rather the names signal they extend rather than replace the built-ins.transloco.config.tsnext to the rest of the keys-manager config rather than on every CLI invocation.provideTranslocoScope/TranslocoServicedetection — TKM's extraction is syntactic throughout, so the custom names follow the same convention rather than introducing import-path resolution.PR Checklist
PR Type
What is the current behavior?
Only
provideTranslocoScope,TRANSLOCO_SCOPE, andTranslocoServiceare recognized for scope detection and service key extraction. Keys used through custom wrappers are not extracted, andfindreports them as extra/missing incorrectly.Issue Number: N/A (resubmission of jsverse/transloco-keys-manager#249)
What is the new behavior?
Custom scope provider function names and custom service class names can be registered via CLI flags or
transloco.config.ts, and are treated exactly like their built-in counterparts during extraction.Does this PR introduce a breaking change?
Other information
Docs for the two new options still need a home — I couldn't find the keys-manager options reference in this repo, so pointers welcome on where to add them (hence the unchecked docs box).
