QEWD, a remarkable Node.js-based platform, is designed for developers looking to build and run web applications efficiently. Whether you’re interested in WebSocket-based applications or REST APIs, QEWD caters to both needs with ease. In this article, we’ll walk you through the steps to set up your first QEWD application, with a straightforward approach that’s perfect for developers at all levels!

What is QEWD?

To put it simply, QEWD provides a framework where you can create an environment that ensures your applications are managed effectively. It operates on a unique architecture which prevents performance issues that can arise from CPU-intensive operations. Plus, it integrates QEWD-JSdb, a powerful multi-model database, presenting your data as persistent JavaScript objects. In essence, it’s like having a trusty toolbox that allows you to build robust applications without the fear of them crumbling under pressure.

Setting Up Your First QEWD Project

Ready to dive in? Let’s get your QEWD application up and running in a few simple steps:

1. Pull the Docker Image

• For standard systems, run the command:

docker pull rtweed/qewd-server

• If you are using a Raspberry Pi, execute this command instead:

docker pull rtweed/qewd-server-rpi

2. Create Your Project Structure

Inside a designated folder (like ~myQEWDApp), set up the following structure:

~myQEWDApp/
  ├── configuration/
  │   ├── config.json
  │   └── routes.json
  └── apis/
      └── helloworld/
          └── index.js

3. Configure Your JSON Files

Update your config.json with:

{
  "qewd_up": true
}

Your routes.json should look like this:

[
  {
    "uri": "api/helloworld",
    "method": "GET",
    "handler": "helloworld"
  }
]

4. Set Up Your API

In your index.js, add this code:

module.exports = function(args, finished) {
  finished({
    hello: "world"
  });
};

5. Run Your QEWD Instance

Initialize the QEWD Docker instance with the command:

docker run -it --name qewdup --rm -p 3000:8080 -v ~myQEWDApp:/opt/qewd-mapped rtweed/qewd-server

For Raspberry Pi users, the command remains the same but uses the Raspberry Pi image.

6. Test Your REST API

Visit the following link in your browser (replacing host-ip-address with your system’s IP address):

http://host-ip-address:3000/api/helloworld

Troubleshooting Tips

If you encounter any issues, here are some troubleshooting ideas:

• Ensure that Docker is correctly installed and running on your system.
• Double-check your folder structure; misnamed files or folders can cause issues.
• Ensure the ports are not being blocked by a firewall.
• For persistent problems, consider visiting the discussion group:
Enterprise Web Developer Community
