Open source · Go · Echo

APIs that stay in sync.

EchoNext adds typed handlers, request validation, and automatic OpenAPI documentation to Echo—without taking away the framework you already know.

One source of truth

Write the contract once.

Your Go types drive binding, validation, responses, and API documentation. Fewer parallel definitions means fewer opportunities for drift.

Typed by default

Request and response structs become the contract. Handler signatures stay explicit and compiler-friendly.

OpenAPI from code

Generate an OpenAPI 3 specification from the same routes and Go types that serve production traffic.

Validation included

Use familiar struct tags and receive consistent validation failures before business logic runs.

CLI workflows

Scaffold projects, generate domains, run development builds, and manage common project tasks.

Beyond REST

Build file uploads, WebSocket hubs, and gqlgen-backed GraphQL endpoints with Echo context access.

Production helpers

Opt into testing, database, config, metrics, request IDs, and OpenTelemetry contrib packages.

Keep Echo. Add confidence.

Progressive, not prescriptive.

Wrap the routes that benefit from a typed contract and keep using standard Echo middleware, groups, context methods, static assets, and error handling everywhere else.

Without a shared contract

Definitions drift across layers

Bind request payloads manually
Invoke validation by hand
Maintain schemas separately
Repeat response envelopes

With EchoNextTypes carry the contractDeclare request and response structs
Register a typed handler
Generate and serve OpenAPI
Keep the complete Echo surface

A practical toolkit

From route to runtime.

Start with the core wrapper. Add only the integrations and contrib packages your service actually needs.

Your next endpoint

Make the implementation and the documentation agree.

Install the stable release, register your first typed route, and let EchoNext carry the repetitive parts.
