express-pipeline v1.1.0

express-pipeline

express-pipeline allows you to put under one name a set of middlewares, when you use the generated middleware all the middlewares are run in the order you define.

These middleware groups are nestable, so you can have one or more groups under another group, and so on.

One limitation is that at the moment they do not support accepting an err, in other words this plugin, at the moment, does not work for pipelining error handling.

Usage

var pipe = require('express-pipeline');

// some middlewares
var loadUser = function (req, res, next) { next() };
var loadFiles = function (req, res, next) { next() };
var loadInfo = function (req, res, next) { next() };
var session = function (req, res, next) { next() };
var token = function (req, res, next) { next() };

// couple of pipelines
var loadStuffPipe = pipe([
  loadUser,
  loadFiles,
  loadInfo,
]);

var securityPipe = pipe([
  session,
  token,
]);

var userPipeline = pipe([
  loadStuffPipe,
  securityPipe,
]);

// Express app
app.all('/Users/*', userPipeline);
