Node.js throws "btoa is not defined" error

How to Fix the "btoa is not defined" Error in Node.js 🚀

So, you're working on your Node.js application and you want to use the btoa() function, but it throws an "btoa is not defined" error. 😩 Don't worry, we've got you covered! In this article, we'll explore the common issues and provide easy solutions to get rid of this pesky error. 💪

Understanding the Problem

The error occurs because the btoa() function is not available in Node.js by default. It is a client-side JavaScript function that encodes a string to Base64. However, fear not! We can easily fix this issue by using a package called btoa-atob. 📦

Solution

Here are the steps to solve the "btoa is not defined" error:

1. Install the btoa-atob package using npm:

   npm install btoa-atob

2. Once the installation is complete, verify that the btoa-atob package is present in the node_modules directory.

3. Ensure that you have added btoa-atob as a dependency in your package.json file. Open the package.json file and check for the following entry:

   "dependencies": { "btoa-atob": "^x.x.x" }

   Note: Replace ^x.x.x with the actual version number of the btoa-atob package.

4. Import the btoa function at the top of your JavaScript file:

   const btoa = require('btoa-atob').btoa;

   Now, you can use the btoa() function in your Node.js application!

5. Test the btoa() function by encoding a string:

   console.log(btoa('Hello World!'));

   You should now see the expected output in the console: "SGVsbG8gV29ybGQh".

Possible Issues and Troubleshooting

1. Incorrect Installation

Double-check if you properly installed the btoa-atob package. Make sure to run npm install btoa-atob in the correct directory.

2. Missing or Incorrect Dependency Entry

Verify that you have added the correct dependency entry for btoa-atob in your package.json file. Check for typos and ensure that the version number is accurate.

3. Importing the Function Incorrectly

Ensure that you are correctly importing the btoa function from the btoa-atob package. Follow the import statement provided in the solution section.
