Building REST APIs can often feel like navigating a maze — with twists, turns, and potential dead ends. Fear not! In this article, we’ll guide you through the process of using the Express Mongoose REST API boilerplate in ES6, making the journey smoother and more intuitive.

Overview of the Boilerplate

This boilerplate serves as a solid foundation for building REST APIs in Node.js using ES6 and Express. It comes packed with code coverage and JWT authentication features, designed to boost productivity while adhering to best practices. Following the Airbnb JavaScript style guide, it offers an array of functionalities that help keep your code clean and efficient.

Key Features

• ES6 via Babel: Support for ES6 syntax through Babel.
• Authentication via JsonWebToken: Simple authentication using jsonwebtoken.
• Code Linting: Ensures adherence to coding standards with ESLint.
• Auto Server Restart: Utilize nodemon for live server reloading on code changes.
• Code Coverage: Analyze your code coverage with Istanbul and run tests using Mocha.
• Debugging: Use the debug library to simplify debugging tasks.
• API Parameter Validation: Validate requests seamlessly with express-validation.
• Docker Support: Easily manage development environments with Docker capabilities.

Getting Started

Ready to dive in? Here’s how to set up your environment quickly:

• Clone the Repository: git clone git@github.com:kunalkapadia/express-mongoose-es6-rest-api.git
• Navigate to Directory: cd express-mongoose-es6-rest-api
• Install Yarn: npm install -g yarn
• Install Dependencies: yarn
• Set Environment Variables: cp .env.example .env
• Start the Server: yarn start

Running Tests and Code Coverage

Testing your code is crucial. Execute the following commands:

• Run Tests: yarn test
• Run Tests with Code Coverage: yarn test:coverage
• Run Tests on File Change: yarn test:watch

Understanding the Code: An Analogy

Think of your code as a well-organized library. The boilerplate sets up the shelves (structure), while the features (like code linting and automated testing) are like librarians ensuring that each book is in its proper place and that new arrivals are cataloged efficiently. This organization helps users (other developers) find what they need quickly and efficiently.

Troubleshooting Your Setup

Here are some common issues and their resolutions:

• Server Not Starting: Ensure that all environment variables are correctly set in your .env file.
• Tests Failing: Check if you have the latest dependencies and ensure that your test cases are written correctly.
• Code Coverage Reports Not Generating: Make sure to run yarn test:coverage correctly and check your .istanbul.yml settings.
• Unexpected Errors: Review logs for detailed error messages using the debug functionality. Set the DEBUG environment variable and restart the server.
