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

To use the outputJsonSync function from the fs-extra package in Node.js, you first need to install the package using npm:

index.tsx
npm install fs-extra

2 lines

Then, you can use the function to write a JSON file synchronously (blocking) like this:

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

const jsonObj = { 
  "name": "John Doe",
  "age": 30,
  "city": "New York"
};

try {
  fs.outputJsonSync('path/to/output/file.json', jsonObj);
  console.log('Data written to file');
} catch (err) {
  console.error(err)
}

In the code snippet above, we are first importing the fs-extra module and assigning it to the variable fs. Then, we are creating a jsonObj object which we want to write to a JSON file.

We are calling the outputJsonSync function of fs using the path to the file we want to write to and the jsonObj object we want to write. Since the function is synchronous, it blocks the execution of the program until the file has been written successfully.

Finally, we are logging a success message to the console if the write was successful, or an error message if it failed.
