Welcome to the comprehensive guide for setting up your Express Mongo JWT Boilerplate! This boilerplate is designed to give you a solid starting point for developing secure Node.js applications using MongoDB and JWT for authentication. Below, we’ll walk through the installation process, Docker setup, and configuration, wrapping it all up with some troubleshooting tips.
Installation Steps
To get your project up and running, follow these simple steps:
- Install NodeJS and MongoDB
- Choose your package manager: either npm or yarn
- Rename the file
.env.exampleto.env - Fill in the required data in your
.envfile - Start your MongoDB server
- Run the application using:
yarn run devornpm run dev - Check the status by navigating to http://localhost:3000/api/status on your web browser
Using Docker
If you prefer using Docker for containerization, here’s a quick guide:
- Ensure you have both Docker and Docker Compose installed.
- Run the command:
docker-compose upto start your server.
Configuration Options
To ensure your application runs smoothly, you need to configure several important settings in your .env file. Here’s a breakdown:
| Name | Description | Example |
|---|---|---|
| NODE_ENV | Environment for Node.js | dev, prod, test |
| APP | Name of your application | My cool express app |
| PORT | Port to run the application (automatically set in Heroku) | 3000 |
| HOSTNAME | Host name for running the application | http://localhost:3000 |
| APP_SECRET | Secret key for application security | ddd36434-80fe-4f18-b3b6-e645697f7b84 |
| MONGOURI | MongoDB connection URI | mongodb://localhost:27017/yourapp |
| MONGOTESTURI | MongoDB connection URI for testing | mongodb://localhost:27017/test-app |
| TRANSPORTER_HOST | Mail server host | smt.myMailer.com |
| TRANSPORTER_PORT | Mail server port | 2525 |
| TRANSPORTER_USERNAME | Mail server username | harrypotter |
| TRANSPORTER_PASSWORD | Mail server password | alohomora |
Analogy to Understand the Setup Process
Imagine you’re building a house (your application). The foundation is laid out using Node.js and MongoDB, while the locks and keys ensure that only those who are authorized (JWTs) can access it. Your .env file is like the blueprint for your house. Without it, you might build something that doesn’t meet your needs. Docker acts as a factory that efficiently builds and produces the house (your app), ensuring it can withstand various conditions without collapsing.
Troubleshooting Tips
If you encounter any issues while setting up the boilerplate, here are some troubleshooting ideas:
- Ensure that Node.js and MongoDB are installed correctly and running.
- Check for any syntax errors in your
.envfile. - Run commands in your terminal with the appropriate permissions.
- If your application doesn’t start, confirm that your variables in the
.envfile are set correctly.
