BannerPlugin
为每个 chunk 文件头部添加 banner。
const webpack = require('webpack');
new webpack.BannerPlugin(banner);
// or
new webpack.BannerPlugin(options);
选项
{
banner: string | function, // 其值为字符串或函数，将作为注释存在
raw: boolean, // 如果值为 true，将直出，不会被作为注释
entryOnly: boolean, // 如果值为 true，将只在入口 chunks 文件中添加
test: string | RegExp | Array,
include: string | RegExp | Array,
exclude: string | RegExp | Array,
}
Usage
import webpack from 'webpack';
// string
new webpack.BannerPlugin({
banner: 'hello world'
});
// function
new webpack.BannerPlugin({
banner: (yourVariable) => { return `yourVariable: ${yourVariable}`; }
});
占位符(placeholder)
从 webpack 2.5.0 开始，会对 banner 字符串中的占位符取值：
import webpack from 'webpack';
new webpack.BannerPlugin({
banner: 'hash:[hash], chunkhash:[chunkhash], name:[name], filebase:[filebase], query:[query], file:[file]'
});
