This package allows you to control the number of concurrent requests being handled by an express application.
While Express and nodeJS in general is capable of handling a large number of requests in parallel, sometimes it's not quite the thing you want.
When a 5000 requests spike comes in and you're allocating a lot of memory in your application, if you're running on a small server, you will face out of memory errors.
This package is for you. You just need to set a maximum concurrent requests, and the rest of the requests will be queued and processed when needed if it reaches the limit.
npm install @hammerbot/express-concurrent
import express from 'express'
import {concurrent} from '@hammerbot/express-concurrent'
const app = express()
app.use(concurrent({
max: 100
}))
app.get('/', (req, res) => {
// Insert some heavy memory processing here
res.send('ok')
})
app.listen(3000)
