JavaScript Password Encryption with Serverless Functions and GraphQL

Protecting user credentials is one of the most critical responsibilities of any web developer. Storing plain-text passwords or using weak encryption leaves your applications vulnerable to severe security breaches. This text-based course guides you through the process of intercepting data requests and securing sensitive information before it ever reaches your database. You will learn to build a secure bridge between your frontend API queries and your data storage using modern serverless architecture. By the end of this course, you will understand how to write clean, secure serverless functions that intercept GraphQL mutations, hash passwords using robust modern algorithms, and implement secure-by-default workflows. What you will learn: Understand the core concepts of serverless architecture and GraphQL mutations; Intercept incoming API requests to process payload data before database persistence; Apply modern cryptographic hashing algorithms like bcrypt to secure user passwords; Configure secure environment variables to manage sensitive API keys and salt rounds; Write clean, modular JavaScript code optimized for serverless environments; Test your serverless function locally to ensure reliable password hashing. The course begins with foundational concepts of API security, GraphQL mutations, and serverless computing. From there, you will progress through practical, written examples that show you exactly how to write, configure, and deploy your encryption function. This course is designed for beginner to intermediate developers who have a basic understanding of JavaScript and APIs but want to master modern, secure serverless workflows. No prior cryptography experience is required. Start reading today to build more secure, modern web applications.
