how to use the outputfilesync function from fs-extra in javascript

To use outputFileSync function from fs-extra module in Node.js, you first need to install fs-extra package using NPM. You can use the following command to install fs-extra package:

npm install fs-extra

Once you have installed the fs-extra package, you can use the outputFileSync function to write a string or a buffer to a file synchronously. Here's an example:

index.tsx
const fs = require('fs-extra');

const filePath = '/path/to/file.txt'; //replace with your file path
const fileContent = 'Hello World!'; //replace with your file content

try {
    fs.outputFileSync(filePath, fileContent);
    console.log('File has been saved.');
} catch (error) {
    console.error(error);
}

In the example code above, we imported the fs-extra module and assigned its outputFileSync function to the constant fs. We then provided a filePath variable with the path to the file we want to write to, and a fileContent variable with the content we want to write. We used a try...catch block to catch any errors that may occur during the write operation, and logged a success message to the console if the operation completed successfully.

Note that outputFileSync overwrites the file if it already exists, and creates the file if it does not exist. If you want to append data to an existing file or create new directories as needed to write a file, you can use outputFile function from fs-extra module.
