middleware-container

``sh $ npm install --save middleware-container`

`Overview`

Middleware container extends the boxed-injector functionality for use with express middleware. The use case for this is when middleware chains get complex.

The problem that this package solves is: - Simplifying declarativeness of common middleware packages (multiple middlewares used often around your app - why declare multiple times?) - Middleware dependency chains (avoid having to declare multiple middleware functions on multiple routes, and having to maintain them in the correct order // with all sub-middlewares) - Middleware redundancy (sometimes middlewares have dependencies that may get executed multiple times if not composed)

`Usage`

middleware-container is built on top of boxed-injector

`js

const MiddlewareContainer = require('middleware-container'); const middlewares = new MiddlewareContainer();

middlewares.register('getOneThing', (req, res, next) => next());

middlewares.register('getAnotherThingThatDependsOnOneThing', (req, res, next) => next(), { depends: 'getOneThing' });

middlewares.register('getSomethingThatDependsOnThePrevious', (req, res, next) => next(), { depends: 'getAnotherThingThatDependsOnOneThing' });

// /foo will have the entire middleware chain executed app.get('/foo', middlewares.get('getSomethingThatDependsOnThePrevious'), (req, res) => res.send(res.locals));
