@hammerbot/express-concurrent v0.0.3

Express Concurrent

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.

Installation

npm install @hammerbot/express-concurrent

Usage

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)
