API REST ​

Configuraremos un Servidor de Express con JWT y MongoDB.

Paso a paso ​

  • Crear Servidor con Express
  • Configurar Rutas de Usuario
  • Validar req.body con Express Validator
  • Conectar a MongoDB a través de Mongoose
  • Crear Schema Usuarios
  • Crear nuevos usuarios en DB
  • Encriptar contraseñas con bcryptjs
  • Generar Token con jsonwebtoken

¿Qué es API REST? ​

Para este ejercicio práctico realizaremos una API REST, que un estándar (reglas y especificaciones) para la transferencia de información entre cliente y servidor, utilizaremos respuestas en JSON y los típicos verbos HTTP: POST, GET, DELETE, PUT.

Ventajas de hacer una API REST (existen más, se los dejo como tarea):

  • Podemos conectar múltiples aplicaciones a nuestro servidor, ya sea página web, aplicación móvil, aplicación para escritorio, etc.
  • Youtube por ejemplo cuenta con una api rest para poder implementar sus videos ya sea desde el sitio web o su aplicación móvil.

JWT ​

JWT (JSON Web Token): https://jwt.io/

  1. Es un token de seguridad que nosotros creamos al momento que el usuario se registra con sus credenciales.
  2. Este token se devuelve al cliente el cual tendrá que enviar cada vez que solicita información al servidor.
  3. Se divide en 3 partes: Header, Payload y Verify Signature: Revisar: https://jwt.io/

Recursos:

Ya que sabemos más o menos como se comportará nuestro login, es momento de configurar nuestro servidor con Express y JWT.

Requisitos ​

const app = express();

// Middleware aceptar req.body y CORS
app.use(express.json({ extended: false }));
app.use(cors());

// Rutas

Rutas ​

NOTA: Se puede llamar a router de diferentes formas:

js
const router = require("express").Router();
js
const express = require("express");
const router = express.Router();
js
const { Router } = require("express");
const router = Router();

routes/api/auth.js

js
const router = require("express").Router();

// Ruta: api/user/signup
// Acceso: Público
// Descripción: Permite crear cuentas de usuario
router.post("/signup", async (req, res) => {
  res.send("ruta signup");
});

module.exports = router;

index.js

js
// Rutas
app.use("/api/user", require("./routes/auth"));

probar en postman:

http://localhost:5000/api/user/signup

Express Validator ​

routes/api/auth.js

js
const router = require("express").Router();
const { body, validationResult } = require("express-validator");

// Ruta: api/user/signup
// Acceso: Público
// Descripción: Permite crear cuentas de usuario
router.post(
  "/signup",
  [
    body("name", "Ingrese un nombre").trim().notEmpty(),
    body("email", "Ingrese un email válido").isEmail(),
    body("password", "Contraseña de 6 o más carácteres").isLength({
      min: 6,
    }),
  ],
  async (req, res) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({
        errors: errors.array(),
      });
    }

    res.send("ruta signup");
  }
);

module.exports = router;
js
// Ruta: api/user/login
// Acceso: Público
// Descripción: Permite accedera a usuarios
router.post(
  "/login",
  [
    body("email", "Ingrese un email válido").isEmail(),
    body("password", "Contraseña de 6 o más carácteres").isLength({
      min: 6,
    }),
  ],
  async (req, res) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({
