Migrate from TSX to native Node.js TypeScript running

convert-imports.js

import fs from 'node:fs'
import path, { dirname } from 'node:path'
import { fileURLToPath } from 'node:url'

const __dirname = dirname(fileURLToPath(import.meta.url))
console.log(__dirname) // Outputs: /absolute/path/to/directory

const updateImports = (directory) =>
	fs.readdirSync(directory).forEach((file) => {
		const filePath = path.join(directory, file)
		if (fs.statSync(filePath).isDirectory()) {
			if (file === 'node_modules') return
			updateImports(filePath)
		} else if (filePath.endsWith('.ts') || filePath.endsWith('.tsx')) {
			let content = fs.readFileSync(filePath, 'utf8')
			content = content.replace(/from ['"](.+?)\.jsx['"]/g, "from '$1.tsx'")
			content = content.replace(/from ['"](.+?)\.js['"]/g, "from '$1.ts'")
			fs.writeFileSync(filePath, content)
			console.log(filePath)
