How to copy package.json in dist or build folder when running tsc (TypeScript compiler)

Question

I have a TypeScript React component that uses a package.json file (see screenshot) and I run tsc in order to transpile it to es5 in my dist folder but the package.json file doesn't get copied. Please note that in the screenshot I manually copied it in the dist folder.

So my question: Is there a way to do this via tsc/tsconfig ... without having to add a copy script (ran via yarn build). Because I would like this to be updated also when running tsc --watch

Also I do NOT wish to rename my Component.tsx to index.tsx in the component folders. I don't want to have 200 index.tsx files in my project and using the package.json's main allow me to have import SomeComponent from './components/SomeComponent' instead of doing import SomeComponent from './components/SomeComponent/SomeComponent' so it's great.

Here is my tsconfig file:

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["dom", "dom.iterable", "esnext"],
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "module": "commonjs",
    "outDir": "dist",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "experimentalDecorators": true,
    "strictPropertyInitialization": false,
    "declaration": true,
    "jsx": "react"
  },
  "include": ["src"]
}

Many thanks for your time and your help or suggestions.

Just include it in your tsconfig.json file and enable the resolveJsonModule compiler option. You can do this by merging the following config into your tsconfig.json file:

{
    "compilerOptions": {
        "resolveJsonModule": true
    },
    "include": ["./package.json"]
}
