Create SVG/TTF/EOT/WOFF/WOFF2 fonts from several SVG icons with PostCSS.

中文文档

postcss-iconfont is based on gulp-iconfont, In the postcss or webpack environment, it is easier to convert svg to webfont.

Install postcss-iconfont as a development dependency:

npm install postcss-iconfont --save-dev

Use iconfont in your script:

var postcss = require('postcss');
var iconfont = require('postcss-iconfont');

var options = {
    outputPath: './dist/fonts/'
};

postcss([iconfont(options)])
    .process(css)
    .then(function(result) {
        fs.writeFileSync('./dist/style.css', result.css);
    });

Use iconfont in your webpack.config.js:

Webpack 1.x

postcss: function () {
    return [
        ...
        iconfont({
            outputPath: './dist/fonts/'
        })
        ...
    ];
}

Webpack 2.x

plugins: [
    new webpack.LoaderOptionsPlugin({
        options: {
            ...
            postcss: [
                ...
                iconfont({
                    outputPath: './dist/fonts/'
                })
            ]
        }
    }),
...
]
