JJC-REVERSE-PROXY

Minimal and convenience library to share the same port between multiple services (api, frontend, auth, ...) using reverse proxies.

How to use

In this example there are 3 servers running in the same machine:

• Frontend server on port 8081
• Api server on port 8082
• Reverse proxy server on port 8080 (the only port accessible from internet)
  The reverse proxy redirects all request to local ports 8081 or 8082 depending on its routes.

import(
    "sync"
    proxy "github.com/jjcapellan/jjc-reverse-proxy"    
)

func main(){
    wg := &sync.WaitGroup{}
    
    // Api server is running and listening on port 8082.
    // All request to routes with path prefix "api" (Example: www.site.com/api/user/23415)
    // will be redirected to port 8082.
    proxy.AddProxy("api", "8082")
    // Frontend server is running and listening on port 8081.
    // Must be at least one proxy configured with this path "\". All request not redirected
    // by other proxies will be redirected to port 8081.
    proxy.AddProxy("/", "8081")

    go func(){
        defer wg.Done()
        wg.Add(1)
        // Starts the main server on public port 8080. All request are received in this port
        // and redirected to the api port or frontend port according to its routes.
        proxy.Start("8080")
        defer proxy.Server.Close()
    }

    wg.Wait()
}

Dependencies

This library is built over standard golang libraries, so it hasn't external dependencies.
