Free JavaScript Library for Parsing & Rendering Fonts

Install Typr.js via npm

 npm install @fredli74/typr --save-dev

You can also install it manually; download the latest release files directly from GitHub repository.

Add SVG Table Parser for SVG Color Font Parsing

Typr.SVG = {};
Typr.SVG.parse = function(data, offset, length)
{
  var bin = Typr._bin;
  var obj = { entries: []};

  var offset0 = offset;

  var tableVersion = bin.readUshort(data, offset);  offset += 2;
  var svgDocIndexOffset = bin.readUint(data, offset);  offset += 4;
  var reserved = bin.readUint(data, offset); offset += 4;

  offset = svgDocIndexOffset + offset0;

  var numEntries = bin.readUshort(data, offset);  offset += 2;

  for(var i=0; i < numEntries ; i++)
  {
    var startGlyphID = bin.readUshort(data, offset);  offset += 2;
    var endGlyphID = bin.readUshort(data, offset);  offset += 2;
    var svgDocOffset = bin.readUint(data, offset);  offset += 4;
    var svgDocLength = bin.readUint(data, offset); offset += 4;

    var svg = bin.readASCII(data, offset0 + svgDocOffset + svgDocIndexOffset, svgDocLength);

    for(var f=startGlyphID; f<=endGlyphID; f++){
      obj.entries[f] = svg;
    }
  }

  return obj;

}

Apply Text Formatting and Styling inside JavaScript Apps

// Assume that Typr.js library is already loaded

// Define the target element where the text will be formatted and styled
const targetElement = document.getElementById('myTextElement');

// Load and parse the font file using Typr.js
Typr.loadFont('path/to/font.ttf', (font) => {
  // Font loading is complete
  
  // Apply the loaded font to the target element
  targetElement.style.fontFamily = font.name.fontFamily;

  // Set text content for the target element
  targetElement.textContent = 'Hello, Typr.js!';

  // Apply text styling
  targetElement.style.fontSize = '24px';
  targetElement.style.letterSpacing = '2px';
  targetElement.style.wordSpacing = '4px';
  targetElement.style.textDecoration = 'underline';

  // Additional text layout adjustments
  targetElement.style.textAlign = 'center';
  targetElement.style.lineHeight = '1.5';
  targetElement.style.textJustify = 'inter-word';
});
