NPM Pack doesn't update all files in the second project

Question

I am creating a npm package using TypeScript and React. To test it I use second testing project by using commands: npm run build npm pack. In the second project I do npm unistall PACKAGE npm i PACKAGE_FILE.tgz

The Package has 3 files, two of them are frequently changing: index.tsx, FormGroup.tsx. When I update the code, index.tsx file shows updates perfectly, while FormGroup.tsx does not. It still has the same code when I first installed it in the Testing Project.

I tried to google it, but no luck

I viewed following places, and see that the new version is there:

1. FormGroup.js in an unpacked PACKAGE_FILE.tgz

2. FormGroup.js file in node_modules/PACKAGE/dist

code in node_modules

But Chrome doesn't show any updated code in the source tab:

Thank you in advance

Some source code:

tsconfig.json

{
  "include": ["src", "__tests__/index.test.js", "babel.config.js", "__tests__/FormGroup.test.js"], /* Include only the src directory */
  "compilerOptions": {
    "jsx": "react",
    "target": "es2016" /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */,
    "module": "commonjs" /* Specify what module code is generated. */,
    "declaration": true /* Generate .d.ts files from TypeScript and JavaScript files in your project. */,
    "outDir": "dist",
    "esModuleInterop": true /* Emit additional JavaScript to ease support for importing CommonJS modules. This enables 'allowSyntheticDefaultImports' for type compatibility. */,
    "forceConsistentCasingInFileNames": true /* Ensure that casing is correct in imports. */,
    "strict": true /* Enable all strict type-checking options. */,
    "skipLibCheck": true /* Skip type checking all .d.ts files. */
  }
