Middleware for adding delays (latency) to your endpoint. Intended to simulate latency for testing its effects on faster networks.
Add a delay of a specified duration by adding an http header to your request.
The header name is X-Add-Delay. The value can be any value parsable by golang's time.ParseDuration. For example, 300ms, 2.5s, and 0.5m are all valid values. Technically -1.5s is a valid value, but it won't actually speed up your end point :p
If the value is not parsable it will not add any latency. It will behave as if the header wasn't there at all.
X-Add-Delay: 300ms
X-Add-Delay: 2.5s
There is no configuration.
Just slip it in as echo middleware:
import (
"github.com/labstack/echo"
"github.com/beenote/delay"
)
e := echo.New()
e.Use(delay.New())
// ...
