1. Setup package.json

package.json

{
  "name": "react-npm-test-reemo-new",
  "version": "1.0.1",
  "description": "",
  "main": "dist/index.js",
  "module": "dist/index.esm.js",
  "types": "dist/index.d.ts",
  "license": "MIT",
  "author": "reemo",
  "homepage": "https://github.com",
  "repository": "https://github.com",
  "scripts": {
    "build": "rimraf dist && tsc",
    "build-roll": "rimraf dist && rollup -c",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "files": [
    "/dist"
  ],
  "keywords": [
    "react",
    "tsx"
  ],
  "devDependencies": {
    "@babel/core": "^7.22.1",
    "@rollup/plugin-babel": "^6.0.3",
    "@rollup/plugin-commonjs": "^25.0.0",
    "@rollup/plugin-node-resolve": "^15.1.0",
    "@rollup/plugin-replace": "^5.0.2",
    "@rollup/plugin-typescript": "^11.1.1",
    "@swc/core": "^1.3.62",
    "@types/react": "^18.2.8",
    "@types/react-dom": "^18.2.4",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "rollup": "^3.24.0",
    "rollup-plugin-filesize": "^10.0.0",
    "rollup-plugin-livereload": "^2.0.5",
    "rollup-plugin-serve": "^2.0.2",
    "rollup-plugin-swc3": "^0.8.2",
    "tslib": "^2.5.3",
    "typescript": "^5.1.3"
  }
}

And install rimraf first.

npm i -g rimraf

2. Setup tsconfig.json

To state that there are several config to notices.

"outDir": "./dist": The builded dir for packages
"include": [...]: The file / folders that will build to src in tsc runtime
"exclude": [...]: The file / folders that will not builded to src in tsc runtime

tsconfig.json

{
    "compilerOptions": {
        "target": "es2016",
        "strict": true,
        "jsx": "react",
        "declaration": true,
        "esModuleInterop": true,
        "outDir": "dist",
        "module": "es6",
        "moduleResolution": "node",
        "resolveJsonModule": true
    },
    "include": [
        "src"
    ],
    "exclude": [
        "node_modules",
        "testing-web",
        "test",
        "bin",
        "template"
    ]
}

3. components

Let’s create a components folder and a counter.tsx in components.

src/components/counter.tsx

import * as React from "react";
 
export function Counter({ num }:{ num: number}) {
  const [count, setCount] = React.useState(num || 0);
  return (
    <>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click me</button>
    </>
  );
}

Also, create a myButton.tsx in components.

src/components/myButton.tsx

import * as React from "react";
 
export function MyButton() {
  return (
    <>
      <button>MyButton</button>
    </>
  );
}

Go back to src, create a index.ts and export the components.

src/utils/index.ts

export { Counter } from "./components/counter";
export { MyButton } from "./components/myButton";

4. Setup `testing-web`

Set up a testing react website for import the components. This time we use vite for create a react runtime.
https://vitejs.dev/guide/

And name the folder testing-web

yarn create vite

5. Setup import to vite

In testing-web/src/App.tsx, delete the preset stuff and import out components.

testing-web/src/App.tsx

import { Counter, MyButton } from "../../src/index"
 
function App() {
  return (
    <>
      <Counter num={10} />
      <MyButton />
    </>
  )
}
 
export default App

Then start the project with yarn start / yarn dev under testing-web folder.

:::note

If you can see the components works, means you are ready to go!
