Usage

This is now a strict ES6 module

import Fontminify from '@sctg/fontminify';

const fontminify = new Fontminify()
    .src('fonts/*.ttf')
    .dest('build/fonts');

fontminify.run(function (err, files) {
    if (err) {
        throw err;
    }

    console.log(files[0]);
    // => { contents: <Buffer 00 01 00 ...> }
});

You can use gulp-rename to rename your files:

import Fontminify from '@sctg/fontminify';
import rename from 'gulp-rename';

const fontminify = new Fontimify()
    .src('fonts/big.ttf')
    .use(rename('small.ttf'));

Sample asynchronous Typescript

import Fontminify from '@sctg/fontminify'
import stream from 'stream'
import gulp from 'gulp'
function convertTTF2WEB(srcPath: string, dstPath: string): Promise<FontminifyFile[]> {
    return new Promise<FontminifyFile[]>((resolve, reject) => {
        const fontmin = new Fontminify()
            .src(srcPath + '/*.ttf')
            .dest(dstPath + '/')
            .use(Fontminify.ttf2woff())
            .use(Fontminify.ttf2woff2())
            .use(Fontminify.css({
                fontPath: srcPath + '/',
            }));

        fontmin.run((err: Error, files: FontminifyFile[], stream) => {
            if (err) {
                reject(err);
            } else {
                resolve(files)
            }
        })
    })
}
