--- package: inversify version: "^6.2.0" tier: feature decision: approved date: 2026-05-14 deciders: [Danijel Martinek] adr: adr-002 lastRevalidated: null is-sub-processor: false processes-pii: false filter-results: license: MIT types: native maintenance: active boundary-fit: pass shadow-check: pass eu-residency: n/a cve-scan: clean named-consumer: pass socketRisk: clean verification-commands: - npm view inversify license - npm view inversify version - pnpm audit --audit-level=moderate accepted-cves: [] --- ## Filter: license `npm view inversify license` returns `MIT`. MIT is on the allowlist. ## Filter: types inversify is authored in TypeScript and ships its own `.d.ts` declaration files. No separate `@types/inversify` package is needed. ## Filter: maintenance Actively maintained; the 6.x line has seen recent releases addressing TypeScript compatibility improvements. Last release < 18 months, issue tracker shows ongoing engagement. ## Filter: boundary-fit ADR-002 explicitly mandates InversifyJS as the DI framework for all feature packages. The ESLint boundary rules (ADR-010) do not restrict inversify to any specific path — feature packages are the declared consumers. ## Filter: shadow-check inversify is the workspace-locked DI container per ADR-002. No parallel DI framework (tsyringe, awilix, etc.) is present or proposed. ## Filter: eu-residency inversify is a pure runtime library with no network communication, telemetry, or data transmission. EU residency does not apply. ## Filter: cve-scan `pnpm audit --audit-level=moderate` reports no advisories against inversify at the time of this trace. ## Filter: named-consumer All five feature packages — `@repo/auth`, `@repo/blog`, `@repo/media`, `@repo/marketing-pages`, `@repo/navigation` — depend on inversify for their per-feature DI containers (ADR-008). Concrete named consumers exist today. ## Prompt: replaces Manual composition root patterns considered during initial architecture setup. InversifyJS replaces ad-hoc factory chaining that would not scale beyond three or four services per feature. No parallel approach is running. ## Prompt: migration-cost-out Hard. InversifyJS container bindings, symbols, and decorator usage are scattered across every feature package's `di/` layer. Migrating out would require replacing all `@injectable()` / `@inject()` decorators, SYMBOLS definitions, and container bind calls across five feature packages simultaneously. The interface boundaries (ADR-002) reduce the surface, but the volume of changes is substantial. The per-feature container pattern (ADR-008) limits blast radius to one package at a time. ## Prompt: alternatives-considered 1. **tsyringe** (Microsoft) — lighter API but fewer lifecycle options and weaker TypeScript inference at the time of evaluation. 2. **Manual composition root** — zero dependency but does not scale past ~5 services without significant boilerplate and loses automatic dependency chain resolution. See ADR-002 for the full decision rationale.
