在營業開闢過程當中，我們經常會重複運用日期格式化、cookie 操縱、模板、瀏覽器推斷、範例推斷等功用。為了防止差別項目之間舉行複製粘貼，能夠將這些經常運用的函數封裝到一同並宣布 npm 包。在快要三年的前端開闢工作中，筆者將本身一樣平常平凡用到的東西庫一切封裝到了一個項目中 Licia。目前所包括模塊已達三百個，基礎能夠滿足前端的一樣平常工發需求。假如你對該項目感興趣，迎接試用並幫助延續革新:)

運用要領

一、裝置 npm 包

起首裝置 npm 包到當地。

npm i licia --save

裝置完以後，你就能夠直接在項目中援用模塊了，就像運用 lodash 一樣。

var uuid = require('licia/uuid');

console.log(uuid()); // -> 0e3b84af-f911-4a55-b78a-cedf6f0bd815

二、運用打包東西

該項目自帶打包東西 eustia，能夠經由過程配置文件或敕令行掃描源碼自動天生項目專用的東西庫。

npm i eustia -g

假定你想html文件中運用trim要領，先直接在代碼中運用：

<html>
<head>
    <meta charset="utf-8"/>
    <title>Eustia</title>
    <script src="util.js"></script>
</head>
<body>
    <script>
    var projectName = _.trim(' Eustia ');
    // Some code...
    </script>
</body>
</html>

然後跑下敕令：

eustia build

該東西會掃描你的html代碼並天生一個util.js(默許文件名)文件，功德圓滿！

PS: 之前做的手機調試東西 eruda 源碼里的 util.js 就是運用該東西天生的:)

三、運用在線東西天生 util 庫

你能夠直接接見 https://eustia.liriliri.io/builder.html 在輸入框輸入須要的東西函數（以逗號分開），然後點擊下載 util.js 文件並將該文件放入項目中去即可。
