koa-echo

Koa Middleware for debugging and mockup purposes. Mirrors the ctx Object as response body, including ctx.params (when used with @koa/router), ctx.query and ctx.request.body and adds a X-Response-Time-Header.

Installation

npm install koa-echo

Usage

import Koa from 'koa'
import { echo } from 'koa-echo'

const app = new Koa()
const port = 3333

app
.use(echo())
.use((ctx) => ctx.status = 204)
.listen(port, () => console.log(`Listening on :${port}`))
