Course Description

** Course Updates **
  • Redux Saga Cheat Sheet - a new Redux Saga Cheat Sheet with example use cases has been included as part of the course so you know what keywords or saga effects to use, and when to use them.
  • Error handling within redux sagas.

Do you want to greatly improve your ability and increase your value as a React or front end web developer?
Redux Saga is the perfect framework for this, and this fast-track redux saga course will help you achieve that!
Please note: that while this course contains lectures on writing redux actions / reducers and React components, these lectures are there for the sole purpose of seeing the thought process behind implementing Redux Saga in a real-world app. The lectures that cover coding Redux actions / reducers and React components offer minimal guidance as it's assumed you already have basic knowledge of these frameworks. This is a course on Redux Saga and not on Redux or React.

Redux saga is a library that aims to make application side effects, like data fetching / calling an API, easier to manage, more efficient to execute, and better at handling failures.

Redux saga is an impressively clean way to separate logic to call API endpoints and update your redux state based on redux actions. The redux saga library's sagas are implemented as Generator functions that yield objects to the redux-saga middleware. The yielded objects are a kind of instruction to be interpreted by the middleware. When a Promise is yielded to the middleware, the middleware will suspend the Saga until the Promise completes. Once the Promise is resolved, the middleware will resume the Saga, executing code until the next yield.

The control that redux saga brings is way beyond any other libraries, such as redux thunk. You have full control of how redux sagas are called, when they're called, and the type of work they do, as well as how they influence the redux store.
In this fast-track introductory course, you will learn:
  • How redux saga fits in to a front end single page application, using React and Redux.
  • What redux sagas are.
  • How to query an API with redux saga - and deal with the response.
  • How to set up a redux saga to listen for dispatched redux actions and the various ways to set up redux saga to listen for dispatched actions.
  • Actually dispatch redux actions from a redux saga and update your redux application state.
  • Learn key redux saga concepts and patterns such as take, takeEvery, takeLatest, fork, put, call as well as blocking and non-blocking calls.
  • Learn some ES6 syntax and learn about Generator functions in Javascript.
You might've used redux-thunk before to handle your data fetching - after taking this course I'm confident you'll switch to using Redux Saga for your future projects!

What other students are saying about this course:
5/5 - "i found the course to be great.. I'm building an application at work which was using Redux-thunk and using what Tom has taught in the course I have remove Redux-Thunk in favour of Redux-Saga and clean up a lot of code. Another reason i like this course as it was only about Redux-Saga. I didn't have watch 5hrs of React & Redux just to get to the part about Redux-Sagas. It was only an afternoon watching and following along and now I feel that I understand Redux-Saga enough to actually use it in a application and know what I'm doing Thanks Tom" - Stefen Hasselberg

5/5 - "This course is exactly what I needed. I hadn't used redux saga before and recently inherited a project that uses it and found it difficult to understand what was going on. This course has helped me a lot in understanding the basics of redux saga - the lecture on javascript generators and the cheat sheet is super helpful - especially the examples in the cheat sheet of when to use certain effects. Overall a great introduction to redux saga. Thanks Tom!" - Carol Emma

5/5 - "So far, very clear and concise explanations with a nice initial overview of the redux-saga process. Look forward to the rest of this course." - Douglas Hanson

5/5 - "Great starting point for learning redux-saga from scratch. Haven't finished yet, but so far I'm convinced I'll be using saga for future projects. I'm now almost at the end of this abbreviated course, and I'd recommend for everyone who uses Redux by far. It's very well done." - Steve BaileyWho this course is for:
  • React developers who want to increase their value and fast-track their way to learning more advanced front-end patterns using Redux Sagas.

Instructor Details

Tom Phillips

Tom Phillips has been developing front end web and mobile apps in the United Kingdom for numerous years. In that time he has had to prepare and teach multiple courses on the latest cutting edge front end web frameworks to junior developers, as well as mentor them during their early days as junior developers. Through doing this, Tom found efficient methods to teach and break down common complex problems that many developers face when trying to get started with new frameworks, especially in such a rapidly changing field as front end web development. Now he's applying those methods to his Udemy courses!
Way back when Tom himself was a junior developer, he was fortunate enough to have been mentored by experts in the field. This allowed him to rapidly progress in his career and understand and architect multiple large projects in his time as an expert front end developer. Now Tom is passing on the buck and sharing his knowledge. Get the same mentoring that Tom received by enrolling on one of his courses and fast-track your understanding and knowledge in front end web development.

Exactly what I was looking for. Professional. It's actually helping me a step further at my new job, thanks!

Not Understand and also the video quality is poor as its blur. There should be one video at the end that should be explained ie final overview for the complete code flow and logics of whatever had explainedThanks!

I have a complex web UI build in Java using Vaadin and have decided on replacing it with React. There are tons of RESTful API calls which I plan to use Sagas to handle.This course was great! The instructor was perfect in every regard (for me). He was no nonsense - fast paced, just focused on redux and sagas and just enough UI stuff to demonstrate the linkages. In one quick course (few hours) all of my questions about redux and sagas were answered.

It is the best explanation on what redux-saga is and how it works, nothing to say more, the explanation is clear and it drives you in a very simple way through the end. The best ever on redux- saga

Great general overview on how ReduxSaga works and great cheatsheet.

Very clear and insightful explanations. Recommended for Redux-Saga revisions as code-along practices - or in case you are a beginners, it's enough to pause the video, rewind and take a moment to digest it.

This course helped me finally wrap my head around the Redux saga concepts. I followed up the course with building a couple demo projects on my own and now using Redux Saga has become as second nature to me as Redux itself. I can finally free my redux actions of all async activities! So long Redux Thunk! :)

More worth than the price and the limited content with easy to practice.It would be more helpful if it was explained more on the each statement why we are using. Anyhave thank yu so much.

Info on saga straightforward enough. Wish there was a starter project if we're skipping project setup steps. Also would appreciate comparison with redux thunk, as well as coding challenges for writing our own sagas.

This is a great, faster paced intro to Redux Saga and all the utility you get with it. You'll definitely want to know React and Redux already, but the instructor is up front about that in the "requirements" listed on course page.

Till now, its going good and perfect.Thanks.

It's a good course. The example in this course is a simple todo but the way that do the things is cool and you can learn a lot if you have expertise using redux and you don't know nothing about sagas.The structure is good and you can try to change the code using hook if any problem. It's an easy problem
