Load & Manage Fonts in Node.js

Loading fonts dynamically is one of Fontra's core functionalities. The open source Fontra API makes it easy for software developers to load various types of fonts and perform different operations inside JavaScript applications. The API’s font loading mechanism ensures efficient and optimized font loading, reducing the risk of font-related errors and improving overall performance. Fontra provides robust tools for managing fonts, including methods to check if a font is loaded, unload fonts, and list all loaded fonts. Here is a simple example that shows how to load fonts inside web application.

import { loadFont } from 'fontra';

loadFont('Roboto').then(() => {
    console.log('Roboto font has been loaded successfully');
}).catch(error => {
    console.error('Failed to load Roboto font', error);
});

Font Manipulation & Performance Optimization

Fontra allows software developers to load and manipulate fonts by adjusting their properties such as weight, style, and variant. This flexibility ensures that fonts can be tailored to fit the design requirements of the application. By managing fonts programmatically, Fontra helps optimize web performance. Developers can load fonts conditionally based on user interactions or other criteria, ensuring that resources are used efficiently. The following example shows, how software developers can load fonts and apply various types of properties inside JS apps.

import { loadFont, applyFontProperties } from 'fontra';

// Load a font and apply properties
loadFont('Open Sans').then(() => {
    applyFontProperties('Open Sans', {
        weight: 700,
        style: 'italic'
    });
    console.log('Open Sans with properties has been applied');
});

Font Discovery and Search in Web Apps

The open source Fontra API provides complete support searching fonts inside JavaScript applications. The API is very easy to handle and provides capability for searching out fonts based on various criteria like style, weight, and classification. This is particularly useful when developers want to explore font options programmatically or build a font selection tool within their web application. The below snippet demonstrates a simple search for fonts with the family name 'Roboto'. The returned object contains metadata, including available styles, weights, and download URLs.

const fonts = fontra.searchFonts({ family: 'Roboto' });
console.log(fonts);

Font Metadata Access Support

The Fontra API allows software developers to access detailed font metadata, such as family name, category, available subsets, and more inside their own web applications. This feature is crucial for developers who need to make informed decisions about font choices based on characteristics like language support or style diversity. This code retrieves detailed information about the 'Roboto' font, including its available variants and supported subsets.

const fontDetails = fontra.getFont('Roboto');
console.log(fontDetails);
