nodejs btoa

The btoa function in Node.js is used to encode a string in Base64 format. It takes a string as input and returns a Base64 encoded string as output. Here's an explanation of each step involved in using the btoa function:

Step 1: Importing the btoa function To use the btoa function in Node.js, you need to import it from the btoa module. This can be done using the require keyword, like this:

const btoa = require('btoa');

Step 2: Calling the btoa function Once the btoa function is imported, you can call it with a string as input. For example:

const encodedString = btoa('Hello, World!');

In this example, the btoa function is called with the string 'Hello, World!' as input.

Step 3: Retrieving the encoded string The btoa function returns the Base64 encoded string as output. In the example above, the encoded string is stored in the variable encodedString.

Step 4: Using the encoded string You can then use the encoded string for various purposes, such as sending it over a network or storing it in a database.

That's it! This is how you can use the btoa function in Node.js to encode a string in Base64 format.
