🚀 MyExpress

A lightweight Express-like framework that I built for fun. While I won’t be implementing all the features of Express, I’ll be adding the essential ones to keep the project clean and functional.

✅ Checklist

• Basic app with send, post, res, req, and next methods.
• Recreated some libraries to reduce dependencies (better for security).
• Interfaces to keep the code clean and maintainable.
• Function to send an HTML file to the client.
• More built-in middlewares.
• Additional tests.

⚡ Features

• send(data) → Sends an object or text directly to the client.
• json(data) → Returns a JSON response.
• download(filePath) → Sends a file to be downloaded by the client.
• redirect(url) → Redirects the client to a specific URL (public domain or local project file).
• sendFile(filePath) (in development...) → Sends the content of a file to the client (currently supports only .txt files).

📌 Usage

Some quick examples of how to use it:

response.send("Hello, client!"); // Sends a text response  
response.json({ hello: "world" }); // Sends a JSON response  
response.download("./download.test.txt"); // Forces a file download  
response.redirect("https://example.com"); // Redirects the user  
response.sendFile("./index.html"); // (Coming soon!) Sends the content of a file  

Note: The sendFile method is still under development and currently only supports .txt files

🔧 Installation

First, clone the repository:

git clone https://github.com/criszst/MyExpress.git

Navigate into the project directory:

cd MyExpress

Then, install dependencies:

npm install

If you want to run tests (optional but recommended):

npm run test

Since Node.js can't run TypeScript files directly, compile the project:

npm run build

Finally, start the server:

npm run start

🌍 Running the Server

The server runs on port 3000. Once it's up, visit:

http://localhost:3000

You should see the message:
Hello, world!
