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

To use the outputFileSync function from the fs-extra library in TypeScript, you need to do the following:

1. Install the fs-extra library:

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

2. Import the fs-extra library in your TypeScript file:

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

3. Use the outputFileSync function to write data to a file synchronously:

   index.ts
   const data = 'Hello, World!';
   const filePath = '/path/to/file.txt';
   
   try {
     fs.outputFileSync(filePath, data);
     console.log(`Data written to ${filePath} synchronously`);
   } catch (err) {
     console.error(err);
   }
   212 chars
   10 lines

   In the above example, we are writing the string Hello, World! to a file at path /path/to/file.txt using the outputFileSync function. If the write is successful, we print a message to the console. If there is an error, we log the error to the console.

   Note that outputFileSync creates any missing directories in the file path, so you don't need to check if the directory exists before calling this function.
