我一直在尝试通过webpack加载一个jquery插件。 此插件打包为npm模块,其依赖项仅包含jquery。 我认为webpack加载了jquery的实例,而不是使用我提供的全局提供的ProvidePlugin。 我尝试了另一个stackoverflow帖子(Managing jQuery plugin dependency in webpack)中提供的所有解决方案,但他们没有成功;结果总是一样的:“terminal()不是函数”。 如果我手动修改node_modules文件夹中的包,删除package.json中的jquery依赖项,并在node_modules插件文件夹中下载的依赖项webpack成功地将该插件与jquery的全局实例绑定。 我知道,我可以简单地创建该包的一个分支并使用私有的npm存储库,但我想使用官方包。
这是我的webpack配置:
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var CleanWebpackPlugin = require('clean-webpack-plugin');
var CopyWebpackPlugin = require('copy-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var moment = require('moment');
var path = require('path');
var environment = process.env.APP_ENVIRONMENT || 'dev';
module.exports = {
entry: {
'app': './src/main.ts',
'polyfills': './src/polyfills.ts',
'vendor': './src/vendor.ts'
},
/*devtool: 'source-map',*/
output: {
path: './dist',
filename: '[name].browser.' + moment().format('DDMMYYYYHHmm') + '.js'
},

{ test: /\.css$/, include: path.resolve('src/app'), loader: 'raw-loader' },
{

},

我通过稍微修改我的Webpack配置解决了我的问题。 正如这里建议的那样(Managing jQuery plugin dependency in webpack),我添加了一个jquery别名。 在提供的示例中,别名是静态指定的,它对我没有用。 我切换到动态值,这解决了问题。
这是片段:
alias: {
'jquery': path.resolve(path.join(__dirname, 'node_modules', 'jquery'))
},

不熟悉jquery.terminal,但明确告诉插件如何加载jQuery可能有所帮助。对于类似的问题,我必须为几个插件执行此操作。
loaders: [{
test: /jquery.terminal.+\.(js)$/,
loader: 'imports?jQuery=jquery,$=jquery,this=>window'
}]

对于package.json
软件包管理器,另一种解决方案是强制使用主应用程序的库依赖项。通过在sub-dependencies
中指定resolutions
,可以防止下载不同版本的"jquery": "~1.12.0"
。除了您的应用程序使用的内容。
如果您的软件包是公开重新分发,则不不使用此解决方案。
问题
例如,如果您的应用程序依赖于jquery-plugin
和dependencies: { "jquery": ">=1.9" }
,其中包括它自己的yarn install
。假设jquery的最新版本为3.4.1,运行node_modules
jquery@1.12.4
jquery-plugin
node_modules
jquery@3.4.1
将下载类似的目录结构。
//app.js
const $ = require('jquery');
require('jquery-plugin');
console.log(typeof $.fn.plugin); //undefined
resolutions
解决方案
在package.json
文件中添加一个{
"name": "project-name",
"dependencies": {
"jquery": "~1.12.0",
"jquery-plugin": "*"
},
"resolutions": {
"jquery": "~1.12.0"
}
}
字段,并定义您的版本替代。
package.json
强制 ALL 子依赖项使用jQuery〜1.12.0
{
"name": "project-name",
"dependencies": {
"jquery": "~1.12.0",
"jquery-plugin": "*"
},
"resolutions": {
"jquery-plugin/jquery": "~1.12.0"
}
}
或强制 jquery-plugin 使用jQuery〜1.12.0
yarn install
然后运行node_modules
jquery@1.12.4
jquery-plugin
。
结果已删除重复的jquery子依赖项。
//app.js
const $ = require('jquery');
require('jquery-plugin');
console.log(typeof $.fn.plugin); //function
