NodeJS module to execute your Express endpoints (middlewares) from your code. This module will let you manually launch all your middleware. It is simulating a client calling your rest APIs, without using a network connection (your server does not even need to listen on a port).

#NodeJS run-middleware

Why?

Many times, your server and your client, need to execute the same functions. For example here is an endpoint to get user details:

app.get('/get-user/:id',function(req,res){
	mysql.query('select * from users where id=?',[req.params.id],function(err,rows){
		res.send({user:rows[0]})
	})
})

Now you want to get the user details from your code. What should you do?

app.runMiddleware('/get-user/20',function(code,body,headers){
	console.log('User Details:',body)
})

Installation

npm i -S run-middleware

var express=require('express')
var app=express();
require('run-middleware')(app)

Support & Contributions

• Pull requests, issues, and English proofreading are welcome on Github.
• Question & support on StackOverflow using run-middlewaretag.

Change request paramaters

As options you can pass the query, body, method, cookies parameters.

app.runMiddleware('/handler',{
		method:'post',
		query:{token:'tk-12345'},
		body:{"action":"list","path":"/"}
	},function(code,data){
		console.log(code,data)
		process.exit()
	})

Auto pass cookies

When you can runMiddleware from another middleware, you can autopass all the parameters of the current middleware, by using the express request object.

app.get('/middleware1',function(req,res){
	// We use res.runMiddleware instead of app.runMiddleware. All the cookies & other data (like socket.io session) will be pass to the second middleware
	res.runMidleware(...)
})

Redirecting

If the middleware you execute will redirect, you will be notified about it, by reading the code and the headers.location

app.runMiddleware('/this-middleware-will-response-as-redirect',function(code,body,headers){
	if(code==301 || code=302) {// Redirect HTTP codes
		console.log('Redirect to:',headers.location)
	}
})
