Apply a middleware only to a group of route handlers in Express
Apply a middleware before or after a group of route handlers in Express. No need to change your existing code, just call this function (see demos below).
npm install express-group-handlersnpm test # Be sure to install the dev dependencies if you want to test this module!
var express =app =groupHandlers = ;groupHandlers;app;app;app;app;
groupHandlers.setup function augments your Express app with two functions,
afterEach. Both work the same way: you supply the middlewares you want to see executed before/after the handlers inside the callback. The callback has one parameter, which is a fake Express app with all router functions (
all etc.). If you give it the same name as your real Express app (as in the example above), no need to change your existing code, just wrap the
beforeEach function around it!
// You can have multiple middlewares in beforeEach/afterEach// You can use arrays of middlewares tooapp;// Alternate syntax if you don't want to augment your Express app// Just don't call groupHandlers.setup and use the functions directly like thisgroupHandlers;// Yodawg, I put a beforeEach inside your beforeEach!app;
Of the above of course works with
afterEach. Actually you can even nest
