Master your TypeScript project setup by understanding the tsconfig.json file!
In this lesson, we break down how to tell TypeScript exactly how to compile your code, where your source files live (rootDir), and where your final JavaScript should go (outDir). Whether you’re a beginner or looking to refine your dev workflow, mastering these compiler options is essential for clean, bug-free code.
⚡ Key Concepts Covered:
• What the tsconfig.json file actually does
• Setting rootDir and outDir to keep code organized
• Enabling strict type checking for production safety
• Creating a clean project structure (src/index.ts – – dist/index.js)
• Target JS versions & module selection
