koa http status

Always response with status code 200 but set real http status in x-http-status header. It helps koa works in some strict environment that does not allow http status other than 200.

Usage

const Koa = require('koa')
const httpStatusHeader = require('@tng/koa-http-status-header')
const app = new Koa()
app.use(httpStatusHeader())
// ...

If response contains error. You will get resp with status code 200 like below.

> GET /some-wrong-request HTTP/1.1
> Host: localhost
> User-Agent: curl/7.54.0
> Accept: */*

< HTTP/1.1 200 OK
(notice the line below)
< x-http-status: 400
< Content-Length: 30
< Content-Type: application/json
