stdi nodejs

Sure! Here is a step-by-step explanation of how to use the stdi module in Node.js:

First, you need to require the stdi module in your Node.js application. You can do this by using the require keyword followed by the name of the module:

const stdi = require('stdi');

Once you have required the stdi module, you can use it to read input from the user. To do this, you can call the read method of the stdi object:

stdi.read((input) => {
  // Code to handle the input goes here
});

The read method takes a callback function as its parameter. This callback function will be called when the user enters input. The input entered by the user will be passed as a parameter to the callback function.

Inside the callback function, you can write code to handle the user's input. For example, you can print the input to the console:

stdi.read((input) => {
  console.log(`You entered: ${input}`);
});

You can also prompt the user for input by using the prompt method of the stdi object. This method takes a prompt message as its parameter and displays the message to the user before waiting for input:

stdi.prompt('Please enter your name: ', (name) => {
  console.log(`Hello, ${name}!`);
});

In this example, the prompt message "Please enter your name: " will be displayed to the user, and the user's input will be passed to the callback function as the name parameter.

Finally, you can use the readLine method of the stdi object to read input line by line. This method takes a callback function as its parameter, and the callback function will be called for each line of input entered by the user:

stdi.readLine((line) => {
  console.log(`You entered: ${line}`);
});

In this example, the callback function will be called for each line of input entered by the user, and the line parameter will contain the current line of input.

That's it! These are the basic steps for using the stdi module in Node.js to read input from the user.
