gateway

Gateway

Minimal API gateway built on top of Fasthttp for proxying requests to @abyan-dev microservices.

To run the app, use:

go run ./cmd/api

The gateway leverages Docker's DNS to proxy requests to corresponding services by their container names. It is also equipped with middlewares for authorization, TLS, and HTTP logger.

Integration

This gateway uses Fiber's Proxy middleware, so all you need to do is catch all routes after your service's domain using a wildcard:

app.All("<url_in_gateway>", func(c *fiber.Ctx) error {
    targetURL := "<target_url>" + c.OriginalURL()[len("<url_in_gateway>"):]
    if err := proxy.Do(c, targetURL); err != nil {
      return err
    }
    c.Response().Header.Del(fiber.HeaderServer)
    return nil
})
