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

To use the readSync function from fs-extra in Node.js, follow the steps below:

1. Install fs-extra using npm. Open your terminal and run the command:

npm install fs-extra

2 lines

2. Import fs-extra at the top of your JavaScript file using the require statement:

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

2 lines

3. Use the readSync function to read the contents of a file synchronously. The function takes two parameters: the path of the file to read and the encoding of the file.

index.tsx
const filePath = 'path/to/your/file.txt';
const fileContents = fs.readFileSync(filePath, 'utf-8');

console.log(fileContents);

5 lines

In the code above, we read the contents of a file located at path/to/your/file.txt in utf-8 encoding. The contents of the file are stored in the fileContents variable, which we then log to the console.

Note that the readFileSync function is synchronous, which means it blocks the event loop until the file has been read. If you need to read a large file, it's better to use the readFile function, which is asynchronous and non-blocking.
