Favicons

What Favicons is

Favicons is a self-hosted Node.js module for generating favicons and related files from local image inputs. You can provide a file path, a buffer, or an array of either. By default, it creates standard favicons, Android home screen icons, Apple touch icons and startup images, Windows tile icons, and a Yandex browser icon. Results include image files and HTML elements, and the module can expose its configuration programmatically. Settings cover app metadata, manifest details, icon backgrounds, display mode, orientation, and which icon groups to generate. Processing happens locally with pure JavaScript and no external dependencies. The project documents installation through NPM and says the software is tested on Node 14 and above. Web manifest support and ICO and PNG exports are included, but SVG export is not. The README notes that some icons are unavailable because required SVG support was not available in pure JavaScript. Favicons is free under the MIT License, which permits use, modification, distribution, sublicensing, and sale subject to its conditions. The license provides the software without warranty.

Who it suits

Favicons may suit developers who want to generate an icon set and related HTML from local image files in a Node.js project. It is less suitable when SVG export is required.

Limits

SVG export is unavailable, and the project notes that some icons are missing because the required SVG support was not available in pure JavaScript.

Getting started

1. Install Node.js 14 or above
2. Install the package with `npm install favicons`
3. Provide a source file path, buffer, or array of paths or buffers
4. Configure metadata, manifest settings, backgrounds, display options, orientation, and icon groups
5. Generate the favicon files, images, and HTML elements

Verdict

Favicons handles local icon generation and configuration in a Node.js workflow, with outputs for several platforms. Note the missing SVG export and some unavailable icons before relying on a particular asset.
