Overview
This skill is a concise, practical guide to the Echo web framework for Go. It explains installation, routing, request/response binding, middleware, static assets, server startup, and observability integrations. Use it to build scalable, high-performance REST APIs and web applications with Echo v4.
How this skill works
The guide inspects common Echo patterns and APIs: route definitions, context helpers (Param, QueryParam, Bind, FormValue, FormFile), response helpers (JSON, XML, String, File), and middleware usage. It covers serving static files and embedded assets, multipart file uploads, session handling, observability (OpenTelemetry and Sentry), and structured logging with zerolog. Sample code snippets show typical startup, TLS/H2C servers, and custom server configurations.
When to use it
- Building REST APIs or web apps in Go where low latency and minimal overhead matter
- Need fast, expressive routing with path and query parameter handling
- Require middleware for logging, auth, CORS, compression, or tracing
- Serving static sites or single-page apps, including embedded assets
- Integrating observability (tracing, error tracking) and structured logging
Best practices
- Bind request bodies to typed structs for validation and type safety
- Apply middleware at root, group, or route level to scope cross-cutting concerns
- Return clear HTTP status codes and explicit error responses
- Group related routes to share middleware and simplify maintenance
- Use echo.Context helper methods for consistent request/response handling
- Integrate tracing and structured logs (OpenTelemetry + zerolog) for observability
Example use cases
- Quick API prototype: define routes, bind JSON to structs, return JSON responses
- File upload endpoint: accept multipart form files, stream to storage, respond with metadata
- Static SPA hosting: serve embedded web assets with middleware.StaticWithConfig
- Admin routes with protection: group-level BasicAuth or JWT middleware
- Production server: start TLS/HTTP2 or custom http.Server with timeouts and observability
FAQ
Use Echo v4 for current features and middleware compatibility; enable Go modules with go mod init and go get github.com/labstack/echo/v4.
How do I handle file uploads safely?
Use c.FormFile to access uploaded files, stream contents (avoid loading large files into memory), validate file size/type, and store to safe destinations with proper permissions.
How do I add tracing and error tracking?
Add OpenTelemetry middleware (otelecho) and Sentry middleware (sentry-go/echo). Initialize tracer/exporter and Sentry client at startup, then use e.Use to attach middleware for automatic spans and error reporting.
