What are the best synchronous libraries for Node.js?

Some of the best synchronous libraries for Node.js include 'fs' for file system operations, 'child_process' for executing shell commands, and 'crypto' for cryptographic functions. Would you like to know more about any specific library?

Can you explain how to use the 'fs' library synchronously?

Sure! To use the 'fs' library synchronously, you can use methods like 'fs.readFileSync()' to read files and 'fs.writeFileSync()' to write files. For example, to read a file, you would do:

const fs = require('fs');
const data = fs.readFileSync('example.txt', 'utf8');
console.log(data);

This will read the content of 'example.txt' synchronously.

What are the drawbacks of using synchronous libraries?

The main drawbacks of using synchronous libraries in Node.js are that they can block the event loop, leading to performance issues, especially in I/O operations. This can make your application less responsive under heavy load.
