router

This is a simple HTTP router library that does not have built-in support for middleware, but that doesn't preclude the use of other middleware libraries. Handler functions are nearly identical to the normal ServeHTTP(http.ResponseWriter, *http.Request) but the request object has been extended to include path variables and query parameters in a field named Params.

Features

• Uses the same machinery as the standard HTTP server.
• Should integrate well with all available middleware libraries.
• Decodes path variables and query parameters.
• AddRoute function can be chained.

Usage

func Example() {
    // Sample search handler.
    search := func(writer http.ResponseWriter, request *Request) {
        fmt.Printf("Search for: \"%s\"\n", request.Params["s"])
        writer.WriteHeader(200)
    }

    // Sample get resource handler.
    getBookByIsbn := func(writer http.ResponseWriter, request *Request) {
        fmt.Printf("Get book with ISBN = %s\n", request.Params["isbn"])
        writer.WriteHeader(200)
    }

    // build the router.
    router := NewRouter().
        AddRoute("GET", "/search",      search).
        AddRoute("GET", "/book/{isbn}", getBookByIsbn)

    // Start the server.
    server := httptest.NewServer(router)
    defer server.Close()

    http.Get(server.URL + "/search?s=stuff+to+search+for")
    http.Get(server.URL + "/book/978-0316371247")

    // OUTPUT: Search for: "stuff to search for"
    // Get book with ISBN = 978-0316371247
}
