In the world of web development, establishing a solid architecture for your Node.js project is crucial. Today’s guide aims to shed light on creating a Bulletproof Node.js architecture, drawing inspiration from the blog post titled Bulletproof Node.js Project Architecture. So grab your favorite code editor and let’s get started!

Prerequisites: Node Version

Before diving into development, ensure you have Node version 14.9.0 installed. You can easily manage Node versions using NVM. Here’s how:

• Install Node version 14.9.0 using:

nvm install 14.9.0

• Activate the installed version:

nvm use 14.9.0

• Run the following command to install required packages:

npm install

• Finally, start your server with:

npm run start

Setting Up Online with Gitpod

If you’re looking for a one-click setup, Gitpod is your friend! With a single click, you can launch a workspace that automatically:

• Clones the Bulletproof Node.js repository.
• Installs dependencies.
• Runs `cp .env.example .env`.
• And starts the application using `npm run start`.

Open your online workspace through this link: Gitpod Workspace.

Understanding API Validation

We use a package called Celebrate for API validation. This allows you to define the expected format for incoming requests at a route level, making it easier for frontend developers to understand your API without relying on quickly outdated documentation. Here’s a simplified analogy:

Think of API Validation like a Restaurant Menu: Just as a menu clearly outlines what a diner can expect to order, API validation specifies the required ingredients (data fields) for each dish (API endpoint). This clarity ensures that customers (frontend developers) don’t order something that’s unavailable (spelling errors or missing data).

js
route.post(signup, celebrate({
    body: Joi.object({
        name: Joi.string().required(),
        email: Joi.string().required(),
        password: Joi.string().required(),
    }),
}), controller.signup)

Your Project Roadmap

To ensure a clear development path, here’s a roadmap of features to implement:

• – [x] API Validation layer (Celebrate + Joi)
• – [ ] Unit tests examples
• – [ ] Cluster mode
• – [x] The logging layer
• – [ ] Add agenda dashboard
• – [x] Continuous integration with CircleCI
• – [ ] Deploy script and documentation for AWS Elastic Beanstalk and Heroku
• – [ ] Integration tests with Newman
• – [ ] Instructions on TypeScript debugging with VSCode

Documenting Your API

To facilitate better API documentation, we incorporate Optic. After setting up the CLI tool, you can run:

api exec npm start

This command captures your endpoints during development. To review and add them to your API spec, use:

api status -- review

Frequently Asked Questions

Where should I put the FrontEnd code?

It’s not advisable to serve static assets directly through Node.js. Instead, focus on your favorite frontend framework separately—it will work seamlessly with your Node backend, regardless of whether you prefer Angular, React, or Vue.

Can I add more layers to this architecture?

Additions can lead to complexities. While it’s understandable to consider alternatives like the Serverless Framework, it’s crucial to grow gradually. Let your project flourish and scale when necessary.

Troubleshooting Your Project

If you run into issues along the way, consider these troubleshooting tips:

• Check your Node version with node -v to confirm you’re running 14.9.0.
• Ensure all dependencies are correctly installed; re-run npm install if needed.
• Review your .env file for misconfigurations.
• If your server isn’t starting, look for error messages in the console.
