You need to save cookie after login request, use cookie in next request.

var cookie = null
login()

function login() {
    request(host)
        .post('/rest/user/login')
        .send({email: 'email@domain.com', password: 'qweqwe'})
        .expect('Content-Type', /json/)
        .expect(200)
        .end(function (err, res) {
            if (err) throw err
            if (!res.body.error) {
                cookie = res.headers['set-cookie']
                nextRequest()
            }
        })
}
function nextRequest() {
    request(host)
        .post('/rest/data')
        .set('cookie', cookie)
        .send({
            data: 'data'
        })
        .expect('Content-Type', /json/)
        .expect(200)
        .end(function (err, res) {
            if (err) throw err
            console.log(res.body.data)
    })
}

As your wish request example, this tested. Here are simple use.

var request = require('request');
var host = 'http://localhost'
var loginUrl = host + '/rest/user/login'
var nextUrl = host + '/rest/next/request'

var j = request.jar()


function login(jar, callback) {
    request.post({url: loginUrl, jar: jar}, callback).form({username: 'user1', password: 'pass1'})
}

function post(jar, callback) {
    request.post({url: nextUrl, jar: jar}, callback).form({id: 1})
}
login(j, function (err, response, body) {
    //check err, response, body
    post(j, function(err, response, body){
        //check err, response, body
        console.log(body)
    })
})
