CzLink

CzLink is a Node.js package for creating and serving zip files from specified input paths. It includes basic functionality to zip files or directories and serve them over HTTP with progress updates.

Installation

To install CzLink, run:

1npm install czlink

Usage

1. Setup and Zip

First, set up the zip process and start the server:

1const czlink = require('czlink');
2
3czlink({
4  sourceFolder: './data',  // Folder to be zipped
5  outputFolder: './backups',  // Folder where the zip files will be saved
6  expressAlr: false,  // If true, it will not start the express server
7  port: 4000  // Custom port for the Express server
8});

2. Access the File

Once the server is running, you can download the zip file using the following URL:

http://localhost:PORT/download/backup.zip

Replace PORT with the port number specified in the czlink() function call.

If Express Server is Already Running

If an Express server is already running, you can serve the zip files without starting a new server by setting expressAlr: true in the options:

1const czlink = require('czlink');
2
3czlink({
4  sourceFolder: './data', // Folder to be Backup
5  outputFolder: './backups', // Folder where the zip files will be saved
6  expressAlr: true,  // If true, it will not start the express server
7  port: 4000 // Custom port for the Express server
8});

Then, in your existing Express server, add this route to serve the zip file:

1let outputFolder = "your_output_folder_goes_here";
2app.use('/download', express.static(outputFolder));

This will allow your server to serve the zip files created by CzLink at the /download endpoint.

API

czlink(options)

Sets up the zip process and optionally starts an Express server.

Parameters

• sourceFolder (string): The path to the folder or directory that will be zipped.
• outputFolder (string): The path to the folder where the zip files will be saved.
• expressAlr (boolean): If true, it will not start a new Express server but expects an existing one to handle file downloads.
• port (number, optional): The port number to start the Express server on if expressAlr is false (default is 3000).

HTTP GET /download/backup.zip

Starts the download of the zip file.

---

Notes

• The zip file will be named backup.zip and stored in the outputFolder.
• The outputFolder is recreated each time the zip process runs.
• The server logs zip progress in the console.
• If an Express server is already running and expressAlr is true, you can use the outputFolder path to serve the zip file from your existing server.
