A Node.js module for generating favicons and their associated files. Originally built for Google's Web Starter Kit and Catalyst. Requires Node 4+. Installed through NPM with:
npm install favicons
To use Favicons, require the appropriate module and call it, optionally specifying configuration and callback objects. A sample is shown on the right. The full list of options can be found on GitHub.
The Gulp / Grunt wrapper modules have a few extra properties. You can also configure and use Favicons from the terminal with dot syntax.
Favicons generates its icons locally using pure Javascript with no external dependencies.
Please note: Favicons is tested on Node 10.13 and above.
var favicons = require('favicons'),
source = 'test/logo.png', // Source image(s). `string`, `buffer` or array of `string`

// Platform Options:

//
android: true, // Create Android homescreen icon. `boolean` or `{ offset, background, mask, overlayGlow, overlayShadow }`

},
callback = function (error, response) {
if (error) {
console.log(error.message); // Error description e.g. "An unknown error has occurred"
return;
}
console.log(response.images); // Array of { name: string, contents: <buffer> }
console.log(response.files); // Array of { name: string, contents: <string> }
console.log(response.html); // Array of strings (html elements)
};
favicons(source, configuration, callback);
You can programmatically access Favicons configuration (icon filenames, HTML, manifest files, etc) with:
var config = require('favicons').config;
To use Favicons with Gulp, you can either use the gulp-plugin or call it manually as follows:
var favicons = require("favicons").stream,
log = require("fancy-log");
gulp.task("default", function () {
return gulp.src("logo.png").pipe(favicons({
appName: "My App",
appShortName: "App",
appDescription: "This is my application",
developerName: "Hayden Bleasel",
developerURL: "http://haydenbleasel.com/",
background: "#020307",
path: "favicons/",
url: "http://haydenbleasel.com/",
display: "standalone",
orientation: "portrait",
scope: "/",
start_url: "/?homescreen=1",
version: 1.0,
logging: false,
html: "index.html",
pipeHTML: true,
replace: true
}))
.on("error", log)
.pipe(gulp.dest("./"));
});
For the full list of files, check config/files.json
. For the full HTML code, check config/html.js
. Finally, for the full list of icons, check config/icons.json
.
Why are you missing certain favicons?
Because pure Javascript modules aren't available at the moment. For example, the El Capitan SVG favicon and the Windows tile silhouette ability both require SVG support. If modules for these task begin to appear, please jump on the appropriate issue and we'll get on it ASAP.
What is the difference between apple and appleIcon?
See webhint explanation on why a single 180x180 touch icon might be the best solution: https://webhint.io/docs/user-guide/hints/hint-apple-touch-icons/:
Over time as Apple released different size displays for their devices, the requirements for the size of the touch icon have changed quite a bit [...]. Declaring one 180ร180px PNG image, e.g.:
<link rel="apple-touch-icon" href="apple-touch-icon.png">
in the of the page is enough, and including all the different sizes is not recommended as:
-
It will increase the size of the pages with very little to no real benefit (most users will probably not add the site to their home screens).
-
Most sizes will probably never be used as iOS devices get upgraded quickly, so [most iOS users will be on the latest 2 versions of iOS]app store stats and using newer devices.
-
The 180ร180px image, if needed, [will be automatically downscaled by Safari, and the result of the scaling is generally ok][icon scaling].
The only downside to using one icon is that some users will load a larger image, while a much smaller file would have worked just as well. But the chance of that happening decreases with every day as users upgrade their devices and their iOS version.
