Webpacker/Typescript 无法解析 rails 资产管道文件

Question

我正在尝试导入 rails 资产管道中的文件，但出于某种原因 webpack 找不到它。

这是我的 tsconfig.json:

{
  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es6", "dom"],
    "module": "es6",
    "moduleResolution": "node",
    "sourceMap": true,
    "target": "es5",
    "baseUrl": ".",
    "paths": {
      "@images/*": ["app/assets/images/*"],
    }
  },
  "exclude": [
    "**/*.spec.ts",
    "node_modules",
    "vendor",
    "public"
  ],
  "compileOnSave": false
}

这是我的 config/webpack/environment.js:

const { environment } = require('@rails/webpacker')
const customConfig = require('./custom');
const typescript =  require('./loaders/typescript')
const fileLoader = require('./loaders/file');

environment.loaders.append('file', fileLoader)
environment.loaders.append('typescript', typescript)

// Merge custom config
environment.config.merge(customConfig);

module.exports = environment

我的config/webpack/custom.js:

const path = require('path');

module.exports = {
  resolve: {
    alias: {
      '@src': path.resolve(__dirname, '..', '..', 'app/javascript'),
      '@images': path.resolve(__dirname, '..', '..', 'app/assets/images'),
      '@components': '@src/components',
      React: 'react',
      ReactDOM: 'react-dom'
    }
  }
};

import "@images/ajax-circle.gif"; 在我的一个 typsecript 文件中给出错误 2307（无法解析模块）并且 webpack-dev-server 无法编译并出现以下错误：

ERROR in /Users/brandoncc/dev/my_app/app/javascript/lib/store_management.ts
[tsl] ERROR in /Users/brandoncc/dev/my_app/app/javascript/lib/store_management.ts(1,24)
      TS2307: Cannot find module '@images/ajax-circle.gif'.
webpack: Failed to compile.

看起来错误又回到了 typescript not being able to resolve the file，但我不明白为什么找不到它。

Answer 1

如果您依赖打字稿 paths 功能，则需要使用 tsconfig-paths-webpack-plugin 来正确解析路径。只需将其添加到您的 webpack 配置中

const TsconfigPathsPlugin = require('tsconfig-paths-webpack-plugin');

module.exports = {
  ...
  resolve: {
    plugins: [new TsconfigPathsPlugin({ /*configFile: "./path/to/tsconfig.json" */ })]
  }
  ...
}

Answer 2

原来我需要为 .gif 扩展名添加一个定义。

正在创建 typings.d.ts：

declare module "*.gif";

已修复。
