JavaScript Library

Browser and Node.js compatible implementation with interactive web interface for GBL file manipulation.

Installation

Node.js

npm install gbl-ninja

Usage

Parse GBL File

// Parse existing GBL file
const gbl = new Gbl();
const parseResult = gbl.parseByteArray(gblFileBytes);

if (parseResult.type === 'Success') {
    console.log(`Parsed ${parseResult.resultList.length} tags`);
    // Process tags
} else {
    console.error(`Parse error: ${parseResult.error}`);
}

Create GBL File

const builder = Gbl.GblBuilder.create()
    .application(32, 0x10000, 0, 54)
    .prog(0x1000, firmwareData);

const gblBytes = builder.buildToByteArray();

File Upload (Browser)

const fileInput = document.getElementById('file-input');
fileInput.addEventListener('change', function(event) {
    const file = event.target.files[0];
    const reader = new FileReader();
    
    reader.onload = function(e) {
        const arrayBuffer = e.target.result;
        const uint8Array = new Uint8Array(arrayBuffer);
        const result = gbl.parseByteArray(uint8Array);
        // Process result
    };
    
    reader.readAsArrayBuffer(file);
});
