How do I use include and exclude in tsconfig.json?

In tsconfig.json, the 'include' and 'exclude' properties specify which files to compile. 'include' lists files to include, while 'exclude' lists files to ignore.

Can you give me an example of how to set that up?

Sure! Here's an example:

{
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}
``` This setup includes all files in the 'src' directory but excludes 'node_modules' and 'dist'.

What happens if I don't specify include or exclude?

If you don't specify 'include' or 'exclude', TypeScript will include all .ts files in the directory and subdirectories by default, except for those in 'node_modules'.

Is there a way to include specific file types only?

Yes! You can specify file types in the 'include' array, like this:

"include": ["src/**/*.ts", "src/**/*.tsx"]
``` This will include only TypeScript and TSX files.
