- 2. ● Mongoose ● Model & Validations ● Controllers ● Routes Recap of last week var mongoose = require('mongoose'); //Define a schema var Schema = mongoose.Schema; var SomeModelSchema = new Schema({ a_string: String, a_date: Date }); var SomeModel = mongoose.model('SomeModel', SomeModelSchema );
- 3. const express = require('express'); //import express const router = express.Router() const teaController = require('../controllers/tea'); router.post('/tea', teaController.newTea); module.exports = router Express and Routes // newTea function for post tea route const newTea = (req, res, next) => { res.json({message: "POST new tea"}); //dummyfuncti }; module.exports = {newTea}; route.js /controllers/tea.js const express = require ('express'); const routes = require('./routes/tea'); const app = express(); app.use(express.json()); app.use('/', routes); //to use the routes const listener = app.listen(process.env.PORT || 3000, () => { console.log('Your app is listening on port ' + listener.address().port) }) server.js
- 4. module.exports = (app) => { const brands = require('../controllers/brand.controller.js'); // Create a new brand app.post('/brands', brands.create); // Retrieve all brands app.get('/brands', brands.findAll); Creating CRUD REST Basic GET & POST
- 5. // Retrieve a single brand with brandId app.get('/brands/:brandId', brands.findOne); // Update a brand with brandId app.put('/brands/:brandId', brands.update); // Delete a brand with brandId app.delete('/brands/:brandId', brands.delete); } Creating CRUD REST API by ID : GET & UPDATE & DELETE
- 6. // Retrieve a single brand with brandId app.get('/brands/:brandId', brands.findOne); // Update a brand with brandId app.put('/brands/:brandId', brands.update); // Delete a brand with brandId app.delete('/brands/:brandId', brands.delete); } Creating CRUD REST API by ID : GET & UPDATE & DELETE
- 7. The first step of login/register is creating a model defining the schema for user. Then, we'll need to register the model with Mongoose so that we can use it throughout our application. We should add more validations Creating the User Schema in Mongoose var mongoose = require('mongoose'); var UserSchema = new mongoose.Schema({ name: String, email: String, password: String, }, {timestamps: true}); mongoose.model('User', UserSchema);
- 8. ● We use POST to send the user registration info ● We should obviously not to save the password as it is in the body. That’s why we encrypt it ● We might check if the user email already registered. ● We can use “bcrypt” package to do so with function bcrypt.hash() ● We can also use genSalt(10) to add more complexity to the hash Registration and setting User passwords app.post('/register, auth.register);
- 9. ● We also use POST to send the data of login information so it checks in the database without passing them in the URL ● First we check if the user exist so if not we throw error ● Then we check the hashed version of our password using bcrypt.compare() so if matched we login. Login app.post('/login, auth.login);
