Express and Mongo stack user models and endpoints

🏠 Homepage


npm install @zentechdev/emuser --save


Using this library requires that the application has a valid Mongoose connection to a database.

Some handlers require body parameters, somerequire URL parameters, some require authentication, and some are a some combination of those three. Most IDEs will show the handler's documentation comment if you hover over the name of the function, which will tell you what is required for using that handler. Additionally, you can find it in the chart below.

// Import model and handlers
const { User: model, handlers } = require('@zentechdev/emuser');

// Interact with user model, provides direct access to mongoose model
const user1 = User.model.findOne({ username: req.user.username });

// Use user handler in an endpoint, check documentation for handler requirements
const express = require('express');
const router = express.Router();
router.get('/api/v1/login', handlers.postLogin);

Run tests

npm run test


This section will go more in depth into the modules available in this package and provide examples of how to use them.


The models module contains the Mongoose model for the users and utility tokens. The models are used by the handlers to interact with the database. The models can also be used directly to interact with the database.

The first model is the User model. This represents a user in the database. The following table displays the fields of this model.

User Schema

Field Name Type Required
username String Yes
password String Yes
firstName String Yes
lastName String Yes
userType String Yes
email String Yes
image String No


const { User: model } = require('@zentechdev/emuser');

// must call query functions from inside an async function and use
// await or a callback, or use the .then() construction

const getUserByUsername = async (username) => {
    const user await User.findOne({ username: 'user123' });
    return user;

const newUser = new User({
    firstName: 'Test',
    lastName: 'User',
    username: 'testuser123',
    password: 'password2022',
    email: 'test@test.com',
    userType: 'member'
await newUser.save();


The handlers module containts the functions that will interact with the database using the request object and constructing a response using the response object. These functions should be passed directly into the Express router endpoints, as shown below. The requirements to use each function are also shown below

Handler Functions

Function Name Requires Auth URL Params Body Params Purpose
getCurrentUserInfo Yes None None Returns current user's info
getUserAuth Yes None None Returns current user's auth status
getUserInfo Yes username None Returns given user's info
postUser No None username, firstName, lastName, email, userType, and password Registers a new user
postLogin No None username, password Logs a user in and returns a token
postProfilePicture Yes None File object uploaded in a form Updates a user's profile picture with the uploaded image
getProfilePicture No fileName None Returns a profile picture as a download


const express = require('express');
const { handlers } = require('@zentechdev/emuser');
const requireAuth = require('../middleware/auth');

const router = express.Router();

// GET /api/v1/users
// Returns details about current user
// Requires none
router.get('/', requireAuth, handlers.getCurrentUserInfo);

// GET /api/v1/users/auth
// Checks if a user is logged in
// Requires none
router.get('/auth', requireAuth, handlers.getUserAuth);

// GET /api/v1/users/:username
// Returns details about given user
// Requires none
router.get('/:username', requireAuth, handlers.getUserInfo);

// POST /api/v1/users
// Registers a new account
// Requires username, firstName, lastName, email, userType, password
router.post('/', handlers.postUser);

// POST /api/v1/users/login
// Logs a user in
// Requires username, password
router.post('/login', handlers.postLogin);

// POST /api/v1/users/picture
// Updates a user's profile picture
// Requires image file
router.post('/picture', requireAuth, handlers.postProfilePicture);

// GET /api/v1/users/picture/:fileName
// Returns a user's profile picture
// Requires fileName param
router.get('/picture/:fileName', handlers.getProfilePicture);

module.exports = router;
