Destiny

Express TypeScript Starter Project with MongoDB, User Authentication, and Testing

Introduction

This is a starter project for building a RESTful API using Express, TypeScript, MongoDB. It includes user authentication and a simple test route.

Prerequisites

• Node.js and npm installed
• MongoDB installed and running

Installation

1. Clone the repository:

git clone https://github.com/your-username/express-typescript-starter.git

2. Install dependencies:

npm install

Configuration

1. Create a .env file in the root directory and add the following environment variables:

MONGODB_URL=mongodb+srv://abhijitbarman96:barman@destiny-cluster.tzx4lyn.mongodb.net/DestinyDB?retryWrites=true&w=majority&appName=Destiny-Cluster

PORT=7000

JWT_SECRET_KEY=https://randomkeygen.com/

NODE_ENV=

2. Replace your-database-name with the name of the MongoDB database you want to use.

Running the Server

1. Start MongoDB.
2. Run the following command to start the server:

npm start

The server will listen on port 7000 by default.

Routes

The project includes the following routes:

• /api/auth: Authentication routes for user registration and login.
• /api/users: User management routes for CRUD operations.
• /test: A simple test route to verify that the server is running.

Testing

The project includes a simple test for the /test route. To run the tests, run the following command:

npm test

Conclusion

This starter project provides a solid foundation for building a RESTful API with Express, TypeScript, MongoDB, and Jest for testing. It includes user authentication and a simple test route, and can be easily customized to meet your specific requirements.

User Schema for Mongoose

This is a user schema for Mongoose, a popular object modeling tool for MongoDB. It defines the structure and properties of a user document in a MongoDB database.

Prerequisites

To use this schema, you will need to have:

• Node.js and npm installed
• MongoDB installed and running
• Mongoose installed (npm install mongoose)
• Bcryptjs installed (npm install bcryptjs)

Usage

To use this schema, you can import it into your Node.js script and create a model based on it:

import mongoose from "mongoose";
import { UserType } from "./user-schema";

const userSchema = new mongoose.Schema<UserType>(
  {
    email: { type: String, required: true, unique: true },
    password: { type: String, required: true },
    firstName: { type: String, required: true },
    lastName: { type: String, required: true },
  },
  { versionKey: false }
);

const User = mongoose.model<UserType>("User", userSchema);

Schema Details

The schema defines the following properties for a user document:

• _id: This is the unique identifier for each user document. It is automatically generated by MongoDB and should not be set manually.
• email: This is the email address of the user. It is required and must be unique.
• password: This is the password of the user. It is required and is hashed using bcryptjs before being stored in the database.
• firstName: This is the first name of the user. It is required.
• lastName: This is the last name of the user. It is required.

Pre-save Middleware

The schema also defines a pre-save middleware function. This function is executed before a user document is saved to the database. It checks if the password field has been modified. If so, it hashes the password using bcryptjs and then allows the save operation to proceed. This is a common practice for securing user passwords by storing only their hashed versions in the database.

Conclusion

This user schema provides a secure and flexible way to store user data in a MongoDB database. It can be used in a variety of applications, such as authentication systems, user management systems, and e-commerce platforms.

User Login API with Express and JWT

This is a simple user login API built with Express and JWT. It allows users to log in to the system by providing their email and password. If the credentials are valid, a JWT token is generated and sent back to the client.

Prerequisites

• Node.js and npm installed
• A MongoDB database
• A JWT secret key (stored in a .env file)

Installation

Clone the repository and install the dependencies:

git clone https://github.com/your-username/user-login-api-express-jwt.git
cd user-login-api-express-jwt
npm install

Configuration

Copy the .env.example file to .env and add your database connection string and JWT secret key:

cp .env.example .env

Usage

Start the server:

npm start

The API will be available at http://localhost:3000/api/auth/login.

User Authentication with JWT and Cookies

This Node.js script provides a secure user authentication mechanism using JSON Web Tokens (JWT) and HTTP cookies. It's designed to be part of a larger Express-based application.

Functionality Overview

The script handles user registration and sets a secure HTTP cookie named "auth_token" upon successful authentication.

List of Dependencies & devDependencies:

1. npm i cookie-parser npm i --save-dev @types/cookie-parser
