## Install

```sh
$ npm install --save @sctg/fontminify
```

## Usage

This is now a strict ES6 module
```js
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](https://github.com/hparra/gulp-rename) to rename your files:

```js
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  
```ts
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)
            }
        })
    })
}
```

    .use(Fontimify.css({
        fontPath: './',                             // location of font file 
        base64: true,                               // inject base64 data:application/x-font-ttf; (gzip font with css). 
                                                    // default = false

    }));
```

Alternatively, a transform function can be passed as `fontFamily` option.
```js
import Fontminify from '@sctg/fontminify'

const fontminify = new Fontimify()
    .use(Fontimify.css({
        // ...
        fontFamily: function(fontInfo, ttf) {

## CLI

The cli is a work in progress and may produce unexpected results.


```bash
$ npm install -g fontminify
```

```sh
$ fontminify --help

  Usage
    $ fontminify <file> [<output>]
    $ fontminify <directory> [<output>]
    $ fontminify <file> > <output>
    $ cat <file> | fontminify > <output>

  Example
    $ fontminify fonts/* build
    $ fontminify fonts build
    $ fontminify foo.ttf > foo-optimized.ttf
    $ cat foo.ttf | fontminify > foo-optimized.ttf

  Options
    -t, --text                          require glyphs by text
    -b, --basic-text                    require glyphs with base chars
    -d, --deflate-woff                  deflate woff
    --font-family                       font-family for @font-face CSS
    --css-glyph                         generate class for each glyf. default = false
    -T, --show-time                     show time fontminify cost
```

you can use `curl` to generate font for websites running on PHP, ASP, Rails and more:

```sh
$ text=`curl www.baidu.com` && fontminify -t "$text" font.ttf
```
or you can use [html-to-text](https://www.npmjs.com/package/html-to-text) to make it smaller:

```sh
$ npm install -g html-to-text
$ text=`curl www.baidu.com | html-to-text` && fontminify -t "$text" font.ttf
```

what is more, you can use [phantom-fetch-cli](https://www.npmjs.com/package/phantom-fetch-cli) to generate font for `SPA` running JS template:

```sh
$ npm install -g phantom-fetch-cli
$ text=`phantom-fetch http://www.chinaw3c.org` && fontminify -t "$text" font.ttf
```
