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 4.x and above.
var favicons = require('favicons'),
source = 'test/logo.png', // Source image(s). `string`, `buffer` or array of `string`
configuration = {
path: "/", // Path for overriding default icons path. `string`
appName: null, // Your application's name. `string`
appDescription: null, // Your application's description. `string`
developerName: null, // Your (or your developer's) name. `string`
developerURL: null, // Your (or your developer's) URL. `string`
dir: "auto", // Primary text direction for name, short_name, and description
lang: "en-US" // Primary language for name and short_name
background: "#fff", // Background colour for flattened icons. `string`
theme_color: "#fff", // Theme color user for example in Android's task switcher. `string`
display: "standalone", // Preferred display mode: "fullscreen", "standalone", "minimal-ui" or "browser". `string`
orientation: "any", // Default orientation: "any", "natural", "portrait" or "landscape". `string`
start_url: "/?homescreen=1", // Start URL when launching the application from a device. `string`
version: "1.0", // Your application's version string. `string`
logging: false, // Print logs to console? `boolean`
icons: {
// Platform Options:
// - offset - offset in percentage
// - background:
// * false - use default
// * true - force use default, e.g. set background for Android icons
// * color - set background for the specified icons
//
android: true, // Create Android homescreen icon. `boolean` or `{ offset, background }`
appleIcon: true, // Create Apple touch icons. `boolean` or `{ offset, background }`
appleStartup: true, // Create Apple startup images. `boolean` or `{ offset, background }`
coast: true, // Create Opera Coast icon. `boolean` or `{ offset, background }`
favicons: true, // Create regular favicons. `boolean`
firefox: true, // Create Firefox OS icons. `boolean` or `{ offset, background }`
windows: true, // Create Windows 8 tile icons. `boolean` or `{ background }`
yandex: true // Create Yandex browser icon. `boolean` or `{ background }`
}
},
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, do as follows:
var favicons = require("favicons").stream,
gutil = require("gulp-util");
gulp.task("default", function () {
return gulp.src("logo.png").pipe(favicons({
appName: "My 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",
start_url: "/?homescreen=1",
version: 1.0,
logging: false,
html: "index.html",
pipeHTML: true,
replace: true
}))
.on("error", gutil.log)
.pipe(gulp.dest("./"));
});For the full list of files, check config/files.json. For the full HTML code, check config/html.json. 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.
