Ultra High Performance Bulk QR Generator

A high-performance Apify Actor for generating QR codes in bulk. It supports various data types (URLs, Email, WiFi, vCard, etc.), custom styling, and outputs results as individual image files, a summary dataset, and a downloadable ZIP archive.

Features

• High Performance: Built with concurrency in mind using Apify's BasicCrawler, capable of handling thousands of records efficiently.
• Multiple Types: Supports Text, URL, Email, Phone, SMS, WiFi, Geo Location, and vCard.
• Custom Styling: Configure size, margin, colors (light/dark), and error correction levels.
• Flexible Output:
  • Dataset: detailed records with public URLs.
  • Key-Value Store: Individual images (optional configuration) and a zipped archive of all codes.
  • Formats: PNG, SVG, and UTF8 (terminal output).

Input Usage

The actor accepts a JSON input with the following structure:

{
"batchSize":10,
"outputFormat":"png",
"zipResults":true,
"options":{
"width":256,
"margin":4,
"color":{
"dark":"#000000",
"light":"#ffffff"
}
},
"data":[
"https://example.com",
{
"type":"wifi",
"ssid":"MyNetwork",
"password":"pass",
"encryption":"WPA",
"filename":"office-wifi"
},
{
"type":"vcard",
"firstName":"John",
"lastName":"Doe",
"email":"john@example.com"
}
]
}

Data Types

Each item in the data array can be a simple string (treated as text/url) or an object with a type.

Output

1. Dataset: Contains metadata for each generated QR code, including the encoded payload and a public URL to the image (if stored).
2. Key-Value Store:
   • qr-codes.zip: A ZIP file containing all generated QR codes.
   • Individual image files (e.g., qr-0.png, guest-wifi.png).

Performance Tips

• For very large datasets (>10,000 items), increase batchSize (e.g., 50 or 100) based on available memory.
• zipResults is recommended for bulk downloads.
