抓取网站截图

很多网页特别长，直接的电脑截图非常麻烦，用ps等工具也非常麻烦，所以很多人都问我有木有自动抓出截图的软件

Node.js里是有的

嵌入代码中

通过shell是可以做，这是给其他语言调用的，对于Node.js，你可以使用对应模块就好了

$ npm install --save pageres

PhantomJS, which is used for generating the screenshots, is installed automagically, but in some rare cases it might fail to and you’ll get an Error: spawn EACCES error. Download PhantomJS manually and reinstall pageres if that happens.

用法

const Pageres = require('pageres');

const pageres = new Pageres({delay: 2})
    .src('yeoman.io', ['480x320', '1024x768', 'iphone 5s'], {crop: true})
    .src('todomvc.com', ['1280x1024', '1920x1080'])
    .dest(__dirname)
    .run()
    .then(() => console.log('done'));
