Are you looking to create a REST API using Node.js? Look no further! In this article, we will walk you through the step-by-step process of setting up a robust REST API server using Node.js, Express.js, and Mongoose.js for integrating with MongoDB. Let’s dive in!
Prerequisites
Before we start, ensure you have the following installed on your machine:
Manual Setup
Node.js Setup on macOS
sh
# Update Homebrew before installing all dependencies
brew update
# Install Node (+npm) with Homebrew
brew install node
# Install npm dependencies in the project folder
npm install
MongoDB Setup on macOS
sh
# Install MongoDB with Homebrew
brew tap mongodb/brew
brew install mongodb-community
# Create directory for MongoDB data
mkdir -p .data/mongo
# Run MongoDB daemon process with path to data directory
mongod --dbpath .data/mongo
Run the Servers
sh
npm start # alias for node bin/www
Create Demo Data
sh
npm run-script generate # alias for node generateData.js
Using Docker
Alternatively, if you prefer using Docker, follow these steps:
sh
# Run servers
docker-compose up -d --build
# Create demo data
docker exec nodeapi_node_api_1 node generateData.js
Making API Requests
Once your server is running, you can create and refresh access tokens, as well as create and update your article data. Below are examples of how to perform these tasks:
Create and Refresh Access Tokens
sh
http POST http://localhost:1337/api/oauth/token grant_type=password client_id=android client_secret=SomeRandomCharsAndNumbers username=myapi password=abc1234
http POST http://localhost:1337/api/oauth/token grant_type=refresh_token client_id=android client_secret=SomeRandomCharsAndNumbers refresh_token=[REFRESH_TOKEN]
Create Article Data
sh
http POST http://localhost:1337/api/articles title=New Article author="John Doe" description="Lorem ipsum dolar sit amet" images:=[kind:thumbnail, url:http://habrahabr.ru/images/write-topic.png, kind:detail, url:http://habrahabr.ru/images/write-topic.png] Authorization:"Bearer ACCESS_TOKEN"
Get User Information
sh
http http://localhost:1337/api/users/info Authorization:"Bearer ACCESS_TOKEN"
http http://localhost:1337/api/articles Authorization:"Bearer ACCESS_TOKEN"
Frequently Used Modules
Here are some key modules used in this project:
Testing the API
sh
npm test # alias for node .test/server.test.js
Using JSHint
sh
npm install jshint -g
jshint libs/*.js generateData.js
Troubleshooting
If you encounter issues during setup or execution, consider the following troubleshooting tips:
- Ensure all dependencies are correctly installed.
- Check that MongoDB is running before starting the Node server.
- Verify the permissions on data directories if MongoDB fails to start.
- Use the correct ACCESS_TOKEN for making API requests.

Analogy of the Code Flow
Think of the Node REST API setup as organizing a community event:
- **Node.js and Express.js**: They act like the event coordinators, managing how things will run. They set the structure and flow for the attendees (requests and responses).
- **Mongoose.js**: This is akin to the registration desk, collecting and storing the data of attendees in a way that it can be retrieved easily when needed.
- **OAuth2orize and Passport.js**: These are like the security personnel, making sure that only registered attendees can enter the event by checking their access tokens, ensuring privacy and safety.
By combining all these components, you’re able to create a seamless experience for users accessing your API, just as a well-organized event allows guests to enjoy without hassles!
Now you are equipped to create a fully functional Node REST API! Happy coding!
