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

To use the ensureFileSync function from the fs-extra module in Node.js, you first need to install the module:

index.tsx
npm install fs-extra
21 chars
2 lines

Then, you can use the ensureFileSync function to create a file if it doesn't exist, or update the timestamp if it does:

const fs = require('fs-extra');

fs.ensureFileSync('/path/to/my/file.txt');
76 chars
4 lines

This will create the file /path/to/my/file.txt if it doesn't exist, and update its timestamp if it does.

If you want to create a file with some initial content, you can pass a string or a buffer to the function:

fs.ensureFileSync('/path/to/my/file.txt', 'Hello, world!');
60 chars
2 lines

This will create the file /path/to/my/file.txt with the content Hello, world! if it doesn't exist, and update its timestamp if it does.

Note that ensureFileSync doesn't overwrite the file if it already exists, so be careful when passing content to the function. If you want to overwrite the file, you can use the outputFileSync function instead.
