webpack5 添加（资源）缓存

nginx的缓存配置就不写了 直接上webpack的

const path = require('path');
const webpack = require('webpack')
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const ESLintPlugin = require('eslint-webpack-plugin');

process.env.NODE_ENV = 'development'

module.exports = {
