[英]Node.js and jdbc : TypeError: Cannot read property 'url' of undefined
[英]TypeError “Cannot read property 'jquery' of undefined” while using Webpack in Node.js app
警告:我是一名现在的学生,对所有这些都非常陌生,很可能是我错误地应用了解决方案。 我至少尝试过应用可以在以下三个链接中找到的解决方案,但同样的问题仍然存在:
我添加了import $ from "jquery";
到我的入口文件的顶部,这是我的 webpack.config 文件的当前 state:
const path = require('path');
const webpack = require('webpack');
require('bootstrap');
module.exports = {
module: {
rules: [
{
test: require.resolve('jquery'),
loader: 'expose-loader',
options: {
exposes: {
globalName: "$",
override: true
},
}
}
],
},
// assigns root of bundle and beginning of dependency graph (default is ./src/index.js)
entry: './assets/js/script.js',
// webpack will bundle code at entry point and output into folder specified folder (default is ./dist/main.js)
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'main.bundle.js'
},
// default is 'production' mode, which will minify code automatically; in this case we do not want this feature
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
}),
],
mode: 'development'
};
最后,这是我的 package.json:
{
"name": "food-festival",
"version": "1.0.0",
"description": "",
"main": "assets/js/script.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"webpack": "webpack --watch",
"build": "webpack"
},
"repository": {
"type": "git",
"url": ""
},
"author": "",
"license": "ISC",
"bugs": {
"url": ""
},
"homepage": "",
"devDependencies": {
"expose-loader": "^1.0.3",
"webpack": "^5.15.0",
"webpack-cli": "^4.3.1"
},
"dependencies": {
"bootstrap": "^4.5.3",
"jquery": "^3.5.1",
"popper.js": "^1.16.1"
}
}
毕竟……我回答了我自己的问题。 我在 webpack.config 文件的顶部错误地需要引导程序,而不是我的入口文件。 掌心。
