Building a Web Application with JavaScript and IndexedDB Course Syllabus

Overview: This course provides a hands-on introduction to IndexedDB, the powerful client-side storage solution for modern web applications. Over approximately 5 hours of interactive learning, you'll progress from foundational concepts to building a fully functional offline-capable to-do list app. Each module combines concise theory with immediate code experimentation, enabling you to master database creation, transactions, indexing, and data querying through practical exercises.

Module 1: Introduction to IndexedDB

Estimated time: 1 hour

• Understanding what IndexedDB is and when to use it
• Opening and versioning databases
• Creating and managing database connections
• Listing and deleting existing databases

Module 2: Object Stores & Transactions

Estimated time: 1.5 hours

• Creating object stores with primary keys
• Performing read-write and read-only transactions
• Storing and retrieving records using object stores
• Updating and deleting data within transactions

Module 3: Indexes & Cursors

Estimated time: 1.25 hours

• Defining and using indexes for efficient queries
• Creating and configuring cursors to iterate over data
• Querying data using key ranges and directional cursors
• Filtering and sorting results with indexed fields

Module 4: To-Do List Project

Estimated time: 1 hour

• Designing a data schema for a to-do list application
• Integrating CRUD operations into a web interface
• Handling edge cases such as duplicate entries and missing data

Module 5: Conclusion & Next Steps

Estimated time: 0.25 hours

• Reviewing best practices for data integrity and performance
• Planning for offline-first application design
• Exploring next steps: synchronization strategies and schema migrations

Prerequisites

• Basic knowledge of JavaScript (variables, functions, events)
• Familiarity with HTML and DOM manipulation
• Understanding of asynchronous programming concepts

What You'll Be Able to Do After

• Set up and manage client-side databases using IndexedDB
• Perform CRUD operations with transactions and error handling
• Use indexes and cursors to efficiently query and iterate over large datasets
• Build offline-capable web applications with persistent storage
• Design and implement a complete to-do list app with IndexedDB backend
