compose-middleware

Compose Middleware

NPM version NPM downloads Build status Test coverage

Compose an array of middleware into a single function for use in Express, Connect, router, etc.

Installation

npm install compose-middleware --save

Usage

Compose multiple middleware functions into a single request middleware handler, with support for inline error handling middleware.

var express = require('express')
var compose = require('compose-middleware').compose
 
var app = express()
 
app.use(compose([
  function (req, res, next) {},
  function (err, req, res, next) {},
  function (req, res, next) {}
]))

P.S. The composed function takes three arguments. Express.js (and Connect, router) only accept error handlers of four arguments. If you want to return an error handler from compose instead, try the errors export - it works exactly the same, but exposes the four argument middleware pattern.
