我在 JS 中有以下模板字符串:
`<div class="card-img center-auto" alt="Image of ${data.title}" class="${data.imgClass}" style="background-image: url(images/${data.imageName}.JPG)"></div>`
背景图像是一种内联样式,文件路径名data.imageName
在运行时被加载。
图像在 DEV 中加载,如果我在本地打开 PROD 环境,图像就在那里,但是当我将其推送到 Github 页面时,图像是错误 404。我已经等待,因为我知道有时可能需要一些时间才能上传到 GitHub 页面但仍然没有什么。
图片文件夹在与 index.html 相同的根目录中称为“图片”
如何让 Webpack 加载这些图像?我已经尝试过文件加载器、url-loader 并且我配置错误或者应该使用其他东西?谢谢
Webpack 配置开发:
const path = require("path");
module.exports = {
mode: "development",
entry: {
app: "./src/scripts/script.js"
},
devtool: "eval-source-map",
devServer: {
contentBase: "./dev"
},
output: {
filename: "[name].bundle.js",
path: path.resolve(__dirname, "dev")
},
module: {
rules: [
{
test: /\.(png|jpg|gif)$/i,
use: [
{
loader: "url-loader",
options: {
limit: 8192
}
}
]
},
{
test: /\.(png|jpe?g|gif|svg)$/,
use: [
"file-loader",
{
loader: "image-webpack-loader",
options: {
mozjpeg: {
progressive: true,
quality: 65
},
// optipng.enabled: false will disable optipng
optipng: {
enabled: false
},
pngquant: {
quality: "65-90",
speed: 4
},
gifsicle: {
interlaced: false
}
}
}
]
},
{
test: /\.css$/,
use: ["style-loader", "css-loader"]
}
]
}
};
Webpack 产品配置:
const webpack = require("webpack");
const path = require("path");
const UglifyJSPlugin = require("uglifyjs-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin");
module.exports = {
mode: "production",
entry: {
app: "./src/scripts/script.js"
},
devtool: "source-map",
plugins: [
new UglifyJSPlugin({
cache: true,
sourceMap: true
}),
new OptimizeCSSAssetsPlugin({}),
new webpack.DefinePlugin({
"process.env.NODE_ENV": JSON.stringify("production")
}),
new MiniCssExtractPlugin({
// Options similar to the same options in webpackOptions.output
// both options are optional
filename: "[name].css",
chunkFilename: "[id].css"
})
],
output: {
filename: "[name].bundle.js",
path: path.resolve(__dirname, "docs")
},
module: {
rules: [
{
test: /\.(html)$/,
use: {
loader: "html-loader",
options: {
attrs: [":data-src", "img:src"],
minimize: true
}
}
},
{
test: /\.css$/,
use: [MiniCssExtractPlugin.loader, "css-loader"]
},
{
test: /\.svg$/,
loader: "svg-inline-loader"
}
]
}
};
