When it comes to programming languages, Mean is one of the most powerful and widely-used stacks out there. As a developer, I’ve had my fair share of experiences with Mean, and I can confidently say that it’s a game-changer. In this article, I’ll guide you through the process of getting Mean, step by step, sharing personal insights and tips along the way.
Step 1: Install Node.js
The first step to getting Mean is to install Node.js. Node.js is a JavaScript runtime environment that allows you to run JavaScript code outside of a web browser. It’s the foundation on which the Mean stack is built.
To install Node.js, head over to the official Node.js website at https://nodejs.org and download the latest stable version for your operating system. Once downloaded, run the installer and follow the on-screen instructions.
Step 2: Install MongoDB
Mean stands for MongoDB, Express.js, AngularJS, and Node.js. To install MongoDB, visit the official MongoDB website at https://www.mongodb.com and download the Community Server version. Choose the appropriate version for your operating system and run the installer.
During the installation process, make sure to select the option to install MongoDB as a service so that it starts automatically when your computer boots up. This will make it easier for you to work with Mean in the long run.
Step 3: Install Express.js
Express.js is a powerful web application framework for Node.js. It provides a set of features and tools that make it easier to build web applications using Mean.
To install Express.js, open your command line interface and run the following command:
npm install -g express
This command will install Express.js globally on your system, allowing you to use it in any Mean project you create.
Step 4: Install AngularJS
AngularJS is a JavaScript framework developed by Google. It’s designed to build dynamic web applications and plays a crucial role in the Mean stack.
To install AngularJS, open your command line interface and run the following command:
npm install -g angular
Similar to Express.js, this command will install AngularJS globally on your system, enabling you to use it in any Mean project.
Step 5: Start a Mean Project
Now that you have all the necessary components installed, it’s time to start a Mean project. First, open your command line interface and navigate to the directory where you want to create your project. Then, run the following command:
mean init my-mean-project
This command will create a new Mean project in a directory called “my-mean-project”. It will set up the basic structure and dependencies for you, so you can start coding right away.
Step 6: Build and Run Your Mean Application
With your Mean project set up, it’s time to build and run your application. Navigate to the root directory of your project in the command line interface and run the following command:
npm install
This command will install all the dependencies listed in your project’s package.json file.
Once the installation is complete, run the following command to start your Mean application:
npm start
Your Mean application should now be running at http://localhost:3000. Open your web browser and visit this URL to see your application in action.
Conclusion
Congratulations! You have successfully gotten Mean up and running. In this article, we covered the installation of Node.js, MongoDB, Express.js, and AngularJS. We also created a Mean project and started our application.
Remember, Mean is a powerful and versatile stack that allows you to build robust web applications. As you dive deeper into Mean, you’ll discover even more exciting possibilities and functionalities. Happy coding!
