# 首先得安装好npm和node.js !!!
# webpack+phaser+javascript
# 开发配置
初始化项目目录：
npm init -y
安装phaser：
npm install --save phaser
安装webpack和webpack扩展：
npm install --save-dev webpack
npm install --save-dev webpack-cli
安装webpack的copy和clean插件：
npm install --save-dev copy-webpack-plugin
npm install --save-dev clean-webpack-plugin
npm install --save-dev html-webpack-plugin
再创建一个测试脚本：
npm install --save-dev webpack-dev-server
这里有个要说明，如果安装phaser使用npm安装使用--save-dev，那么phaser就会会放到devDependencies。
dependencies：生产环境需要的依赖库；
devDependencies：开发环境需要的依赖库；
创建一个webpack.development.js:
```js
const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const HtmlWebpackPlugin = require("html-webpack-plugin");
module.exports = {
entry: {
// 入口点，即主 JavaScript 文件
app: './src/main.js',
},
output: {
// 输出文件，捆绑了所有库
filename: '[name]-[contenthash].bundle.js',
// 输出包的路径，“dist” 文件夹
path: path.resolve(__dirname, 'dist/test'),
// 静态资源文件
assetModuleFilename: "asset-packs/[name]-[hash][ext][query]",
},
// 处于开发模式
mode: 'development',
// 需要一个源映射
devtool: 'inline-source-map',
plugins: [
new HtmlWebpackPlugin({
template: 'src/index.html', // 指定你的HTML模板
filename: 'index.html', // 输出的文件名
inject: 'body', // 将脚本插入到body底部
}),
new CleanWebpackPlugin(),
new CopyWebpackPlugin({
patterns: [
{ from: 'src/favicon.ico', to: '' },
{ from: 'src/assets', to: 'assets' }
],
}),
],
resolve: {
extensions: [".tsx", ".ts", ".js"],
},
// 开发服务器根目录是 “src” 文件夹
devServer: {
static: './src'
}
};
```
创建一个webpack.production.js:
```js
const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
entry: {
// 入口点，即主 JavaScript 文件
app: './src/main.js',
},
output: {
// 输出文件，捆绑了所有库
filename: '[name]-[contenthash].bundle.js',
// 输出包的路径，“dist” 文件夹
path: path.resolve(__dirname, 'dist/test'),
// 静态资源文件
assetModuleFilename: "asset-packs/[name]-[hash][ext][query]",
},
// 处于生产模式
mode: 'production',
// 需要一个源映射
devtool: 'inline-source-map',
plugins: [
new HtmlWebpackPlugin({
template: 'src/index.html', // 指定你的HTML模板
filename: 'index.html', // 输出的文件名
inject: 'body', // 将脚本插入到body底部
}),
new CleanWebpackPlugin(),
new CopyWebpackPlugin({
patterns: [
{ from: 'src/favicon.ico', to: '' },
{ from: 'src/assets', to: 'assets' }
],
}),
],
resolve: {
extensions: [".tsx", ".ts", ".js"],
},
};
```
package.json中启动脚本改成如下：
```text
"scripts": {
"dev": "webpack serve --open --config webpack.development.js",
"test": "webpack --config webpack.development.js",
"pro": "webpack --config webpack.production.js"
},
```
# 前端相关的代码
创建新目录src，新建文件src/main.js，src/index.html
其中index.html代码如下：
```html
Making your first Phaser 3 Game
```
main.js代码如下：
```js

```
在到src目录下创建asserts，放图片资源。
