Go 的全栈 Web 框架，Revel v0.11.2 发布

jopen 10年前

Revel 是一个Go 语言高效的，全栈Web开发框架，灵感源于Rails 和 Play!。

Hot Code Reload

Edit, save, and refresh. Revel compiles your code and templates for you, so you don't miss a beat. Code doesn't compile? It gives you a helpful description. Run-time code panic? Revel has you covered.

Comprehensive

Revel provides routing, parameter parsing, validation, session/flash, templating, caching, job running, a testing framework, and even internationalization.

High Performance

Revel builds on top of the Go HTTP server, which was recently benchmarked to serve three to ten times as many requests as Rails across a variety of loads.

Synchronous

The Go HTTP server runs each request in its own goroutine. Write simple callback-free code without guilt.

Stateless

Revel provides primitives that keep the web tier stateless for predictable scaling. For example, session data is stored in the user cookie, and the cache is backed by a memcached cluster.

Modular

Revel is built around composable middleware called filters, which implement nearly all request-processing functionality. Developers have the freedom to replace the default filters with custom implementations (e.g. a custom router).
