导入无法识别图像模块在使用带有typescript的webpack的react中 [英] Imports not recognizing image modules in react using webpack with typescript

问题描述

我遇到一个问题，使用Webpack加载图像文件时出现以下错误.如果我使用webpack-dev-server运行该应用程序，则会显示该图像，以便能够将其拉入.

文件夹结构如下:

- home
   -home.tsx
-images
   -test2.png

这是webpack配置文件，我试图在其中模块化要与导入一起使用的图像:

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin')

const config = {
  entry: './src/index.tsx',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/
      },
      {
        test: /\.less$/,
        use: [
          {
            loader: "style-loader"
          },
          {
            loader: "css-loader"
          },
          {
            loader: "less-loader"
          }
        ]
      },
      { 
        test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
        use:'url-loader' 
      },
      { 
        test: /\.(png|jp(e*)g|svg)$/,
        use: [
          {
            loader: "url-loader",
            options: {
              limit: 10000,
              name: 'images/[hash]-[name].[ext]',
            },
          }
        ]
      }
    ]
  },
  resolve: {
    extensions: [ '.ts', '.tsx', '.js' ]
  },
  plugins: [
    new HtmlWebpackPlugin({
        title: 'Application Name',
        template: path.join(__dirname, 'src/index.html')
    })
  ],
  devtool: 'inline-source-map',
  devServer: {
    contentBase: path.join(__dirname, 'dist'),
    historyApiFallback: true,
    compress: true,
    port: 8080
  }
};

module.exports = config;

解决方案

您可以尝试

const testImage = require('../images/test2.png');

因为图像不是模块.所以你不能导入它.

我们可以使用declare module '*.png'导出图像文件 请参阅github中的帖子 >

I am having an issue where I am getting the following error when using webpack to load my image files. If I run the application with the webpack-dev-server, the image will display so it is able to pull it in.

The folder structure looks like so:

- home
   -home.tsx
-images
   -test2.png

This is the webpack config file where I am trying to modularize the images to be used with imports:

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin')

const config = {
  entry: './src/index.tsx',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/
      },
      {
        test: /\.less$/,
        use: [
          {
            loader: "style-loader"
          },
          {
            loader: "css-loader"
          },
          {
            loader: "less-loader"
          }
        ]
      },
      { 
        test: /\.woff(2)?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
        use:'url-loader' 
      },
      { 
        test: /\.(png|jp(e*)g|svg)$/,
        use: [
          {
            loader: "url-loader",
            options: {
              limit: 10000,
              name: 'images/[hash]-[name].[ext]',
            },
          }
        ]
      }
    ]
  },
  resolve: {
    extensions: [ '.ts', '.tsx', '.js' ]
  },
  plugins: [
    new HtmlWebpackPlugin({
        title: 'Application Name',
        template: path.join(__dirname, 'src/index.html')
    })
  ],
  devtool: 'inline-source-map',
  devServer: {
    contentBase: path.join(__dirname, 'dist'),
    historyApiFallback: true,
    compress: true,
    port: 8080
  }
};

module.exports = config;

解决方案

You can try with

const testImage = require('../images/test2.png');

Because image is not module. So you can't import this.

EDIT(by Shawn)

we can export image file with declare module '*.png' See the post in github
