Favicons Webpack Plugin

Leverages on favicons to automatically generate your favicons for you.

Installation

Install the plugin with npm:

$ npm install --save-dev favicons-webpack-plugin

Zero Config Usage

Add your base logo as logo.png file to you webpack context folder.
(By default the context is the current working directory)

Add the plugin to your webpack config as follows:

const FaviconsWebpackPlugin = require('favicons-webpack-plugin')

plugins: [
  new FaviconsWebpackPlugin()
]

Basic Usage

Add the plugin to your webpack config as follows:

const FaviconsWebpackPlugin = require('favicons-webpack-plugin')

...

plugins: [
  new FaviconsWebpackPlugin('/path/to/logo.png') // svg works too!
]

The default configuration will automatically generate webapp manifest files along with
44 different icon formats
as appropriate for iOS devices, Android devices, Windows Phone and various desktop browsers out of your single logo.png.

Tip: You might want to fine tune what vendors to support.

A Note on Path Resolution

Under the hood, Webpack resolves the path to logo according to the following
rules:

• If /path/to/logo is absolute, there is nothing to resolve and the path
  specified is used as is.

• If ./path/to/logo is relative, it's resolved with respect to Webpack's
  context,
  which defaults to process.cwd().

• If path/to/logo is neither explicitly relative nor absolute,
  Webpack attempts to resolve it according to
  resolve.modules,
  which defaults to modules: ["node_modules"].

HTML Injection

In combination with html-webpack-plugin it will also inject the necessary html for you:

Note: html-webpack-plugin must come before favicons-webpack-plugin in the plugins array.

Advanced Usage

plugins: [
  new FaviconsWebpackPlugin({
    // Your source logo (required)
    logo: './src/logo.png',
    // Enable caching and optionally specify the path to store cached data
    // Note: disabling caching may increase build times considerably
    cache: true,
    // Override the publicPath option usually read from webpack configuration
    publicPath: '/static',
    // The directory to output the assets relative to the webpack output dir.
    // Relative string paths are allowed here ie '../public/static'. If this
    // option is not set, `prefix` is used.
    outputPath: '/public/static',
    // Prefix path for generated assets
    prefix: 'assets/',
    // Inject html links/metadata (requires html-webpack-plugin).
    // This option accepts arguments of different types:
    //  * boolean
    //    `false`: disables injection
    //    `true`: enables injection if that is not disabled in html-webpack-plugin
    //  * function
    //    any predicate that takes an instance of html-webpack-plugin and returns either
    //    `true` or `false` to control the injection of html metadata for the html files
    //    generated by this instance.
    inject: true,

    // Favicons configuration options (see below)
    favicons: {
      ...
    }
  })
]

To fine tune what icons/metadata is generated, refer to
favicons' documentation.

The options specified under favicons: are handed over as is to favicons,
except that if appName, appDescription, version, developerName or
developerURL are left undefined, they will be automatically inferred
respectively from name, description, version, author.name and
author.url as defined in the nearest package.json if available.
To disable automatically retrieving metadata from package.json, simply set
to null the properties you want to omit.

Examples

Basic

const FaviconsWebpackPlugin = require('favicons-webpack-plugin')

plugins: [
  new FaviconsWebpackPlugin({
    logo: './src/logo.png', // svg works too!
    mode: 'webapp', // optional can be 'webapp' or 'light' - 'webapp' by default
    devMode: 'webapp', // optional can be 'webapp' or 'light' - 'light' by default 
    favicons: {
      appName: 'my-app',
      appDescription: 'My awesome App',
      developerName: 'Me',
      developerURL: null, // prevent retrieving from the nearest package.json
      background: '#ddd',
      theme_color: '#333',
      icons: {
        coast: false,
        yandex: false
      }
    }
  })
]

To fine tune what icons/metadata is generated, refer to
favicons' documentation.

Handling Multiple HTML Files

const FaviconsWebpackPlugin = require('favicons-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const { basename } = require('path')

...

plugins: [
    new HtmlWebpackPlugin({
        template: 'a.html.tmpl',
        filename: 'a.html',
    }),
    new HtmlWebpackPlugin({
        template: 'b.html.tmpl',
        filename: 'b.html',
    }),
    new FaviconsWebpackPlugin({
        logo: 'logo.svg',
        inject: htmlPlugin => 
          basename(htmlPlugin.options.filename) === 'a.html',
    }),
],

Compilation Modes

Modes allow you to choose a very fast simplified favicon compilation or a production ready favicon compilation

By default this mode is controlled by webpack
If the webpack mode is set to development the favicons mode will use light.
If the webpack mode is set to production the favicons mode will use webapp.

This behaviour can be adjusted by setting the favicon mode and devMode options.

Compatibility

favicons-webpack-plugin 2.x is compatible with html-webpack-plugin 3.x
favicons-webpack-plugin 3.x is compatible with html-webpack-plugin 4.x
