How do I use the glob package to find and read the content of a config.json file in multiple subdirectories?

Answer

Sure, let's dive right in! First, you'll need to install the glob package. Run npm install glob in your project's directory.

npm install glob

Now, you're ready to use glob in your test file. Here's a quick example:

import * as fs from 'fs';
import * as glob from 'glob';

const pattern = '**/config.json';

glob(pattern, (err: Error | null, files: string[]) => {
  if (err) {
    console.error('An error occurred:', err);
    return;
  }

  for (const file of files) {
    try {
      const content = fs.readFileSync(file, 'utf8');
      console.log(`Content of ${file}:`, content);
    } catch (error) {
      console.error(`Error reading ${file}:`, error);
    }
  }
});

In this code, **/config.json matches all config.json files in any subdirectory. We then read and log the contents of each file. Remember to handle any errors that might occur!

This is a basic example, but it should help you get started with reading config.json files in multiple subdirectories using glob. Happy coding!
