how to use the writefilesync function from the fs-extra library in typescript

To use the writeFileSync function from the fs-extra library in TypeScript, you'll need to follow a few steps.

1. First, make sure you have the fs-extra library installed in your project. You can do this by running the following command in your terminal:

   index.ts
   npm install --save fs-extra
   28 chars
   2 lines

2. Next, import the module into your TypeScript file:

   index.ts
   import * as fs from 'fs-extra';
   32 chars
   2 lines

3. Once you've imported the module, you can use the writeFileSync function to write data to a file synchronously:

   index.ts
   try {
     fs.writeFileSync('path/to/file', 'data to write');
     console.log('Data successfully written to file!');
   } catch (err) {
     console.error(err);
   }
   152 chars
   7 lines

   The above example code writes the string 'data to write' to the file located at 'path/to/file'. If the write operation is successful, the console will log 'Data successfully written to file!'. If there's an error, the console will log the error message.

   You can also use the writeFileSync function with different function signatures to specify options like the file encoding, mode, and flag. Consult the official documentation for more details.
