I am using webpack with HtmlWebpackPlugin , html-loader and file-loader .(我正在将Webpack与HtmlWebpackPlugin ， html-loader和file-loader 。)
I have a simple project structure in which I use no frameworks, but only typescript.(我有一个简单的项目结构，其中不使用框架，只使用打字稿。) Thus, I write my HTML code directly to index.html .(因此，我将HTML代码直接编写到index.html 。) I also use this HTML file as my template in HtmlWebpackPlugin .(我还将这个HTML文件用作HtmlWebpackPlugin模板。)
As all websites do I need to put an image which refers to a PNG in my assets folder.(像所有网站一样，我需要在资产文件夹中放置一个引用PNG的图像。)
file-loader should load the file correctly put the new filename inside the src tag but that is not what is happening.(file-loader应正确加载文件，然后将新文件名放在src标记中，但事实并非如此。) Instead, as the value of src tag, I have [object Module] .(相反，作为src标签的值，我有[object Module] 。) I assume the file-loader emits some object and it is represented like this when its .toString() method is run.(我假设file-loader发出一些对象，并且当其.toString()方法运行时，它像这样表示。) However, I can see that file-loader has processed the file successfully and emitted with new name to the output path.(但是，我可以看到file-loader已经成功处理了文件，并以新名称将其发送到输出路径。) I get no errors.(我没有错误。) Here is my webpack configuration and index.html .(这是我的webpack配置和index.html 。)
