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.
