Installation

To get started with this project, follow these steps:

1. Clone the Repository

   git clone https://github.com/jsuyog2/express-sequelize-api.git
   cd express-sequelize-api

2. Install Dependencies

   Ensure you have Node.js and npm installed. Then run:

   npm install

3. Set Up Environment Variables

Create a .env file in the root directory of the project. Configure the environment variables as described in Environment Variables.

Usage

Run Locally

Start the server

  npm run start

Build

To build the project using Webpack, use the following commands:

Production Build

To create an optimized production build:

  npm run build

This command will generate the bundled files optimized for production in the dist directory.

Start the Server

After building the project, you can start the server with:

  npm run prod

This command builds the project (if not already built) and then starts the server using the generated bundle.js file in the dist directory.

Environment Variables

To run this project, you need to configure the following environment variables in your .env file:

• PRODUCTION: Set to true for production mode or false for development mode.
• BASE_URL: The base URL for the application (e.g., http://127.0.0.1:3000).
• PORT: The port on which the application will run (e.g., 3000).
• CORS_LIST: Comma-separated list of allowed origins for CORS (e.g., http://localhost:4200).
• JWT_SECRET: Secret key for signing JWT tokens.
• JWT_PUBLICKEY_PATH: Path to the public key file for JWT verification.
• JWT_PRIVATEKEY_PATH: Path to the private key file for JWT signing.
• SESSION_SECRET: Secret key used for session management.
• SEQUELIZE_CONNECT: Sequelize database connection string (e.g., postgres://postgres:1234@localhost/pgtest).
• MAIL_HOST: SMTP server host for sending emails.
• MAIL_PORT: SMTP server port for sending emails (e.g., 465).
• MAIL_USERNAME: SMTP server username.
• MAIL_PASSWORD: SMTP server password.

Here’s an example .env file with the required variables:

PRODUCTION=false
BASE_URL=http://127.0.0.1:3000
PORT=3000
CORS_LIST=http://localhost:4200

JWT_SECRET=api_secret_key
JWT_PUBLICKEY_PATH=./express-sequelize-api/key/public.key
JWT_PRIVATEKEY_PATH=./express-sequelize-api/key/private.key

SESSION_SECRET=api_session_secret

SEQUELIZE_CONNECT=postgres://postgres:1234@localhost/pgtest

MAIL_HOST=smtp.example.com
MAIL_PORT=465
MAIL_USERNAME=[email protected]
MAIL_PASSWORD=your_email_password

Ensure that you replace the placeholder values with your actual configuration details.

Generating Keys Using OpenSSL

Now you need to create Private and Public Key to generate a Token.

1. Generate an RSA private key, of size 2048, and output it to a file named private.key:

   openssl genrsa -out key/private.key 2048

2. Extract the public key from the key pair, which can be used in a certificate:

   openssl rsa -in key/private.key -outform PEM -pubout -out key/public.key

   Note: Make sure both key/private.key and key/public.key are saved in the key folder.
