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

To use the readFileSync function from the fs-extra package in Node.js, you will first need to install the package by running the following command in your Node.js project directory:

npm install fs-extra
21 chars
2 lines

Once you have installed the package, you can import the readFileSync function by adding the following line to the top of your JavaScript file:

index.tsx
const fs = require('fs-extra');
32 chars
2 lines

With the fs module imported, you can now use the readFileSync function to read the contents of a file synchronously. The function takes a file path as its first argument and an optional encoding parameter as its second argument. Here is an example of how to use the readFileSync function to read a file:

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

try {
  const data = fs.readFileSync('/path/to/file', 'utf8');
  console.log(data);
} catch (err) {
  console.error(err);
}
157 chars
9 lines

In the example above, the readFileSync function is used to read the contents of a file located at /path/to/file with a specified encoding of utf8. The function call is wrapped in a try...catch block to handle any errors that may occur during the file reading process. Finally, the contents of the file are logged to the console.
