What you will learn

RU102JS provides a deep dive into Node.js application development with Redis. You can expect to learn how to make connections to Redis, store and retrieve data, and leverage essential Redis features such as sorted sets and streams.

What you will build

As the course progresses, you'll write code that implements the features of a solar power monitoring application. This real-world project consists of three components:

  • A command-line data loading application
  • A REST API backend using Express
  • A Vue.js front end (No Vue experience required!)

We'll store data in Redis using a data model that we'll develop along the way. The project will leverage a number of Redis data structures, including:

  • Hashes
  • Sets
  • Sorted Sets
  • Geospatial indexes
  • Streams

We'll provide examples of best practices such as the use of pipelining, transactions, and Lua scripting.

We'll also demonstrate several common Redis patterns, including rate-limiting for API calls and leaderboards for top-producing solar sites.

Course Requirements

RU102JS has no course prerequisites. However, we assume that students already understand:

  • The JavaScript programming language (including ES6 features)
  • The Node.js programming model
  • The basics of the Express web application framework
  • Redis and Redis Data Structures (approximately to the level covered in the RU101 course)

Software Requirements

  • Web Browser: Firefox 39.0+ or Chrome 43+ (Internet Explorer is currently not supported)
  • Operating System: Mac OS X 10.7+ 64-bit, Ubuntu 14.04+ 64-bit, or Windows 8+ (64-bit)
  • Access to www.youtube.com and university.redislabs.com (i.e. non-blocked access)
