Installation

npm install -g resource-save-script

Usage

Once installed, use the h command in your terminal:

# Run on a custom port
h 8080

# Run on the default port 4000
h

You'll be prompted to enter the remote server URL:

→ Please enter the base URL for resources: https://your-remote-server.com

How It Works

The script monitors 404 requests on the local server. When a missing file is detected, it automatically downloads the file from the specified remote server to your local directory.

Usage Example

Let's say you want to debug a page from luckfunc.com locally:

1. Create and enter project directory

mkdir my-project
cd my-project

2. Download the main page

curl -o index.html https://luckfunc.com/

3. Start the script in your project directory

h
# Enter: https://luckfunc.com/

4. Access the page

Open your browser and visit http://127.0.0.1:4000/index.html

When the page loads, if it references local files like i18n.js that don't exist, the script will automatically download them from luckfunc.com to your local directory.

Terminal output will show download progress:

Missing file detected: /i18n.js
Download complete: /path/to/your/project/i18n.js (1234 bytes)

Refresh the page and all resources will load properly.

Use Cases

• Local debugging of live websites
• Setting up offline development environments
• Bulk downloading of static resources
