在第三方庫中導入會破壞構建

[英]import in third party library breaks build

我發布了一個 package 文件結構如下:

.
├── index.css
├── index.tsx
├── node_modules
├── package.json
└── yarn.lock

index.tsx 文件正在導入 index.css 文件,如下所示:

import React from 'react'
import './index.css'

export const CustomComponent = ()=> {
   return <span>Hello World</span>
}

命令tc生成一個build目錄。 在 package.json 文件中,我有以下內容:

{
...
"main": "./build/index.js",
  "types": "./build/index.d.ts",
  "files": [
    "build/**/*",
  ],
...
}

一旦安裝了我的 package,您可以在項目 node_modules 目錄中設置與上述相同的文件結構。

現在安裝 package 的項目無法構建,因為它無法識別來自 package index.ts 文件的路徑./index.css 8CBA22E28EB17B5F5C6AE2A266AZ

知道如何解決這個問題嗎?

它不起作用,因為文件index.css在 package 的根目錄中不存在,而是在build/index.css下。

當您使用npm publish package 時,它會維護文件夾結構。 The main in package.json simply points to the default file in your package, it doesn't make /build the root folder of your package.

為了解決這個問題,要么從mypackage/build/index.css (不太理想),要么從build文件夾中調用npm publish ,而不是從父文件夾中發布。

我通過使用 Rollup 解決了這個問題。 查看匯總,typescript 配置和 package.json 文件如下:

// tsconfig.json

   "compilerOptions": {
     "jsx": "react",
     "target": "es5",
     "module": "esnext",
     "sourceMap": true,

     "moduleResolution": "node",
     "declaration": true,
     "outDir": "build",
     "strict": true,
     "esModuleInterop": true,
     "skipLibCheck": true,
     "downlevelIteration": true,
     "forceConsistentCasingInFileNames": true,
     "lib": ["es6", "dom", "es2016", "es2017"]
   },
   "include": ["src"],
   "exclude": ["node_modules", "build"]
 }

// rollup.config.js

import pkg from "./package.json";

export default {
   input: "src/index.ts",
   output: [
      {
         file: pkg.main,
         format: "cjs",
         exports: "named",
         sourcemap: true
      },
      {
         file: pkg.module,
         format: "es",
         exports: "named",
         sourcemap: true
      }
   ],
   plugins: [
      external(),
      resolve(),
      typescript({

         exclude: "**/__tests__/**",
         clean: true
      }),
      commonjs({

            "node_modules/react-dom/index.js": ["render"]
         }
      }),
      json(),
      postcss({
         plugins: []
       })
   ],
   external: nodeExternal()
};
// package.json

{
