express-delay-header
Use case
You want to test your fancy ajax loaders, spinners and stuff, but your dev machine is too damn fast for that shit!
-- boo1ean - creator of express-delay
I couldn't come with a better description than this. This library has the same goal with a few improvements:
- It allows you to control whether or not the delay should be present from the client by passing a
Delay
header with the desired latency. - It'll only kick in when
NODE_ENV
isdevelopment
, so you can safely commit the code to production and have the delay code running only on your local environment.
Installation
npm install express-delay-header --save
Usage
const app = require('express')()
const delay = require('express-delay-header')
app.use(delay())
// ...
Important: make sure the NODE_ENV
environment variable is development
for it to work.
On your client, pass a Delay
header in the request with the desired delay in miliseconds (e.g. 3000
for 3 seconds).
curl --request GET \
--url http://localhost:3000/ \
--header 'delay: 3000'
