Webpack-2b NPM

webpack-2b

webpack-2b is a wrapper of webpack. The target of this tool is creating the libs packing file in easy way.

Getting Started

First install the package: npm install webpack-2b
Building the lib file like this:

// build.js

const webpack2b = require('webpack-2b');
const libsConfig = {
    libs: [
        { src: 'async', expose: 'async' },
        { src: 'lodash', expose: 'lodash' },
        { src: './src/utils.js', expose: 'bbutils' }
    ],
    savePath: './dest/libs.js'
};
webpack2b.libsPack(libsConfig, (err) => {});
...

run node build.js, the lib file will be built and saved as ./dest/libs.js，if you want to using the libs in your page, you can do like this below:

add build action to build.js

// build.js
...
const pagesConfig = {
    pages: [
        { src: ['./src/home.js'], dest: './dest/home.js' },
        { src: ['./src/profile.js'], dest: './dest/profile.js' }
    ],
    externals: webpack2b.getExternals(libsConfig)
};
webpack2b.pagesPack(pagesConfig, (err) => {});

src/home.js

// src/home.js

// you can import the lib directly
import _ from 'loash';
import async from 'async';
import BBUtils from 'bbutils';

async.map([1000, 2000, 3000], function (delay, callback) {
    setTimeout(function () {
        console.log(delay);
        return callback(null, delay);
    }, delay);
}, function (err, results) {
    console.log(results);
});
...

in the html

// home.html

<!DOCTYPE html>
<html>
<head>
    <title>Home</title>
</head>
<body>
    <script type="text/javascript" src="./dest/libs.js"></script>
    <script type="text/javascript" src="./dest/home.js"></script>
</body>
</html>

just enjoy it!
