Capabilities Matrix

Note

TypeScript/Node.js is fully supported with 39 capabilities across all core categories. Some capabilities (grpc, graphql, ddd, nats, bff, sse, websocket, and others) are Go-only in the current release.

Smart Suggestions

When you select capabilities, verikt suggests what you might be missing:

If you select…	verikt suggests…	Why
Any transport capability	platform	Config, logging, lifecycle management
platform	bootstrap	Testable wiring with thin main.go
http-api	rate-limiting, auth-jwt, cors, health	API security and reliability
mysql, postgres	migrations, docker	Schema management and local dev
mysql, redis, postgres	docker	Local dev with dependencies
Any transport	ci-github, linting	Code quality and CI/CD
email-gateway	i18n, mailpit	Translations and local testing

Caution

verikt also warns about problematic combinations — like using MySQL without migrations, or running an HTTP API without health checks. These are warnings, not blockers.
