我正在从这个template开始构建一个vue应用程序。 现在我写了一些组件,我想在npm注册表中发布它们,以便能够在其他项目中导入它们,就像任何其他npm库一样。问题是运行
npm run build
输出许多.css / .map / .js文件。 我想要实现的是像mylibrary.min.js这样的输出,我可以导入它最终做类似的事情:
npm install myLibrary --registry myregistry
之后:
import myLib from "mylibrary";
或
import Component1 from "mylibrary/lib/myLibrary.min.js";
有办法吗?在这种情况下,最佳做法是什么?谢谢你的帮助!

这回答了您要在哪里创建单个文件的问题。
创建webpack.prod.conf.js
的副本并将其命名为webpack.npm.conf.js
。从本质上讲,这与创建块相关的所有部分都被注释掉并由单个文件引用替换。这是我的:
'use strict'
const path = require('path')
const utils = require('./utils')
const webpack = require('webpack')
const config = require('../config')
const merge = require('webpack-merge')
const baseWebpackConfig = require('./webpack.base.conf')
const CopyWebpackPlugin = require('copy-webpack-plugin')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
const env = require('../config/prod.env')
const webpackConfig = merge(baseWebpackConfig, {
module: {
rules: utils.styleLoaders({
sourceMap: config.build.productionSourceMap,
extract: true,
usePostCSS: true
})
},
devtool: config.build.productionSourceMap ? config.build.devtool : false,
output: {
path: config.build.assetsRoot,
filename: utils.assetsPath('js/bundle.js'),
// filename: utils.assetsPath('js/[name].[chunkhash].js'),
// chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')
},
plugins: [
// http://vuejs.github.io/vue-loader/en/workflow/production.html
new webpack.DefinePlugin({
'process.env': env
}),
new UglifyJsPlugin({
uglifyOptions: {
compress: {
warnings: false
}
},
sourceMap: config.build.productionSourceMap,
parallel: true
}),
// extract css into its own file
new ExtractTextPlugin({
filename: utils.assetsPath('css/bundle.css'),
// filename: utils.assetsPath('css/[name].[contenthash].css'),
// Setting the following option to `false` will not extract CSS from codesplit chunks.
// Their CSS will instead be inserted dynamically with style-loader when the codesplit chunk has been loaded by webpack.
// It's currently set to `true` because we are seeing that sourcemaps are included in the codesplit bundle as well when it's `false`,
// increasing file size: https://github.com/vuejs-templates/webpack/issues/1110
// allChunks: true,
}),
// Compress extracted CSS. We are using this plugin so that possible
// duplicated CSS from different components can be deduped.
new OptimizeCSSPlugin({
cssProcessorOptions: config.build.productionSourceMap
? { safe: true, map: { inline: false } }
: { safe: true }
}),
// generate dist index.html with correct asset hash for caching.
// you can customize output by editing /index.html
// see https://github.com/ampedandwired/html-webpack-plugin
new HtmlWebpackPlugin({
filename: config.build.index,
template: 'index.html',
inject: true,
minify: {
removeComments: true,
collapseWhitespace: true,
removeAttributeQuotes: true
// more options:
// https://github.com/kangax/html-minifier#options-quick-reference
},
// necessary to consistently work with multiple chunks via CommonsChunkPlugin
// chunksSortMode: 'dependency'
}),
// keep module.id stable when vender modules does not change
// new webpack.HashedModuleIdsPlugin(),
// enable scope hoisting
new webpack.optimize.ModuleConcatenationPlugin(),
// split vendor js into its own file
// new webpack.optimize.CommonsChunkPlugin({
// name: 'vendor',
// minChunks (module) {
// // any required modules inside node_modules are extracted to vendor
// return (
// module.resource &&
// /\.js$/.test(module.resource) &&
// module.resource.indexOf(
// path.join(__dirname, '../node_modules')
// ) === 0
// )
// }
// }),
// extract webpack runtime and module manifest to its own file in order to
// prevent vendor hash from being updated whenever app bundle is updated
// new webpack.optimize.CommonsChunkPlugin({
// name: 'manifest',
// minChunks: Infinity
// }),
// This instance extracts shared chunks from code splitted chunks and bundles them
// in a separate chunk, similar to the vendor chunk
// see: https://webpack.js.org/plugins/commons-chunk-plugin/#extra-async-commons-chunk
// new webpack.optimize.CommonsChunkPlugin({
// name: 'app',
// async: 'vendor-async',
// children: true,
// minChunks: 3
// }),
// copy custom static assets
new CopyWebpackPlugin([
{
from: path.resolve(__dirname, '../static'),
to: config.build.assetsSubDirectory,
ignore: ['.*']
}
])
]
})
if (config.build.productionGzip) {
const CompressionWebpackPlugin = require('compression-webpack-plugin')
webpackConfig.plugins.push(
new CompressionWebpackPlugin({
asset: '[path].gz[query]',
algorithm: 'gzip',
test: new RegExp(
'\\.(' +
config.build.productionGzipExtensions.join('|') +
')$'
),
threshold: 10240,
minRatio: 0.8
})
)
}
if (config.build.bundleAnalyzerReport) {
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin
webpackConfig.plugins.push(new BundleAnalyzerPlugin())
}
module.exports = webpackConfig
这只会为名为bundle.js
和bundle.css
的捆绑包创建两个文件。
然后转到build
文件夹并复制build.js
,并将其命名为build.npm.js
。修改第12行,使其使用webpack.npm.conf.js
:
const webpackConfig = require('./webpack.npm.conf')
最后,打开package.json
并转到scripts
部分,添加以下内容:
"build-npm": "node build/build-npm.js"
现在您可以使用
创建所需的构建类型npm run build-npm
