ex-js-faker-request

A simple way to emulate request in ExpressJS project to get data from inner controller whithout calling rest http (no axios, request or http method) only internal functions

If we have a controller function made using express like this

controller.getAllusers = async function(req,res){
    
    let list = await users.find({name:req.body.name, company:req.params.company}).limit(req.query.limit).exec()
    
    res.status(200).json({
        status:200,
        data:list,
        error:'none'
        
    })
}

module.exports = controller

Commonly we use this in a route like this

let {getAllusers} = require('usercontroller.js')

router.post('/getAllusers', getAllusers)

But if we have to get the info internal is a litle complex and must of people use axios, request or another http request but is not very efficient. To solve this problem we can execute like this

//Import library
let {fakeRequestFunction, fakeResponseFunction} = require('ex-js-faker-request')

//Import controller
let {getAllusers} = require('usercontroller.js')

// create the fake req objet as json object


let main = async function (){
    
    let req = {
        body:{name:'erick'},
        params:{company:'leganux'},
        query:{limit:5},
    }

// make the instance of fake functions
    let fakeResUser = new fakeResponseFunction()
    let fakeReqUser = new fakeRequestFunction(req)
    
     await getAllusers(fakeReqUser,fakeResUser)
    
    console.log(fakeResUser.status_)
    /* console:  
    200 
    */
    console.log(fakeResUser.json_)
    /* console: 
    {
        status:200,
        data:[{},{}],
        error:'none'
    } 
    */  
}

main()
