好的,學習反應,es6和webpack/babel。我得到了我webpack.config設置如下:ES6模塊,babel/webpack。導入/導出語句不起作用
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const merge = require('webpack-merge');
const validate = require('webpack-validator');
const parts = require('./config/webpack-parts');
const PATHS = {
app: path.join(__dirname, 'app'),
build: path.join(__dirname, 'build')
};
const HTMLWebpackPluginConfig = new HtmlWebpackPlugin({
template: PATHS.app + '/index.html',
filename: 'index.html',
inject: 'body'
});
const common = {
entry: {
app: PATHS.app
},
output: {
path: PATHS.build,
filename: '[name].js'
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: "babel-loader"
}
]
},
plugins: [HTMLWebpackPluginConfig]
};
var config;
switch(process.env.npm_lifecycle_event) {
case 'build':
config = merge(
common,
{
devtool: 'source-map',
output: {
path: PATHS.build,
filename: '[name].[chunkhash].js',
// This is used for require.ensure. The setup
// will work without but this is useful to set.
chunkFilename: '[chunkhash].js'
}
},
parts.clean(PATHS.build),
parts.extractBundle({
name: 'vendor',
entries: ['react']
}),
parts.minify(),
parts.extractCSS(PATHS.app)
);
break;
default:
config = merge(
common,
parts.setupCSS(PATHS.app),
{
devtool: 'eval-source-map'
},
parts.devServer({
// Customize host/port here if needed
host: process.env.HOST,
port: process.env.PORT
})
);
break;
}
module.exports = validate(config);
的「配置/的WebPack零部件」文件只是一些額外的模塊/插件和不需要的問題。只是旨在使這個項目可重用。我得到了巴貝爾設置還和.babelrc文件低於
{
"presets": [
"es2015",
"react"
]
}
我也有我的package.json文件中安裝的所有nesscary巴貝爾/插件的WebPack:
"devDependencies": {
"babel-core": "^6.11.4",
"babel-loader": "^6.2.4",
"babel-preset-es2015": "^6.9.0",
"babel-preset-react": "^6.11.1",
"clean-webpack-plugin": "^0.1.10",
"css-loader": "^0.23.1",
"extract-text-webpack-plugin": "^1.0.1",
"html-webpack-plugin": "^2.22.0",
"style-loader": "^0.13.1",
"uglify-loader": "^1.3.0",
"webpack": "^1.13.1",
"webpack-dev-server": "^1.14.1",
"webpack-merge": "^0.14.1",
"webpack-validator": "^2.2.7"
},
"dependencies": {
"react": "^15.3.0",
"react-dom": "^15.3.0"
}
所以,現在的問題。我測試了這一切工作,並使用babel將es6 +反應代碼轉換爲es5。我設置了測試'hello.js'和'world.js'文件,並將它們導入到我的入口/主文件索引中.js文件。這是錯誤的地方。
hello.js
import React, {Component} from 'react';
export class Hello extends Component {
render() {
return (
<h1>Hello</h1>
)
}
}
world.js
import React, {Component} from 'react';
export class World extends Component {
render() {
return (
<h1>World</h1>
)
}
}
index.js
import React, {Component} from 'react';
import ReactDOM from 'react-dom';
import Hello from 'hello';
import World from 'world';
ReactDOM.render(<Hello/>, document.getElementById('hello'));
ReactDOM.render(<World/>, document.getElementById('world'));
預Web Pack中的index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Weather App</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
</head>
<body>
<div id="hello"></div>
<div id="world"></div>
</body>
</html>
當我運行網絡包執行它的操作時,出現以下網絡包錯誤。
ERROR in ./app/index.js
Module not found: Error: Cannot resolve module 'hello' in /Users/Foysal/Google Drive/Learning Projects/ReactJS-Tutorial/weather-app/app
@ ./app/index.js 11:13-29
我得到了「world.js」文件類似的錯誤,我不知道什麼是錯的導入/導出報表。我只是新的es6模塊,但我已經正確導出和導入,據我所知。我將不勝感激任何幫助,謝謝。
這些文件與索引有關嗎? – aw04
我檢查了下面的正確答案。這與文件與索引有關的地方有關。 – Foysal94
