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 stars - "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 stars - "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 stars - "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 stars - "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 Bailey

- it's good enough for beginners in Redux-Saga, - I expected using my time more efficient - 2 reasons why I got rating 4 instead of 5 and which should be improved: -- a little outdated - it's based on class components when the functional components with hooks were introduced in February 2019 -- json-server is a very nice and simple solution for so short project without deepen in any external resources BUT why you changed conception in mid of project (to be honest it was closer to the beginning than to the middle)
By Victor López on 2/11/2023
Exactly what I expected, short and straight to the point. Not loosing time on explaining other things; just Redux-Saga. I don't remember if this is a beginners course, but if it is it'd be good to let know the students that basic JS and React skills is expected; otherwise students will have a hard time understanding this course. Other than that I liked the course a lot.
By Bijay Singh on 5/14/2020
I was always shy from using generator functions and thought redux sagas are not my cup of tea. But after taking this course am confident enough that am gonna use redux saga in my react projects for handling side effects. Tom is to the point and explains things in a pretty and concise manner.
By Stephen Matthai on 4/22/2020
I thought this was well done and well organized. The instructions were clear and concise. I did not feel lost at any time through out the lectures. You definitely walk away with an understanding of redux sagas, it was greatly appreciated. This would have been amazing for me if there were another example or two, just to really drive it home while doing example based learning. Perhaps one that demonstrated the explanation of why the generator functions were so helpful. Maybe a bit more discussion on the saga workflow and some additional diagrams that would be helpful to recall the lessons.

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.
By Gregory Tippett on 4/16/2019
A good course, would recommend it. Relative to other tutorials, it requires the student to pause a lot more to review and look at the larger-scale structure and connect intermediary steps. That requires more work on the student's part, which is probably a good thing actually. However it would be good for the instructor to explain this style a bit more at the outset. (Compare with Steven Grider's courses, which are much more fine-grained in their explanations and make fewer assumptions about the student's knowledge.) One bit of negative feedback: the text size is small and low-contrast, which makes studying on smaller monitors difficult, especially since the student will half-screen to be able to code along.
By Anish kumar dubey on 2/14/2019
The course is very much introductory. The course is not detailed enough to understand redux-saga fully. The app that we are making during course is not big enough to understand redux-saga. Only single app was made during course. It should have been like after the single app was made during learning then another app should have been made to check and understand are we able to apply redux-saga into new project or not.
By Alishan Ali on 1/19/2019
Great explanation of Redux Saga! It is a complicated technology to teach, but you did well. I can now jump into it and help my team implement this at work. This course is straight-forward and expects students to know Javascript and React-Redux before watching. This is good for people who want to learn Redux Saga fast! I appreciate your hard work! Thanks and keep making more guides! To Tom Phillips: Please make sure your GitHub Source Code repository is updated with all the code which was shown in the last videos. I see it's missing some code in the reducers file which was already written in the last video... please check and update - https://github.com/tomphill/redux-saga-course
By Aleksandr Sinkevič on 12/18/2018
Good course. Probably the best thing I learned is "fork" helper theory and why we need to use it, to have separate threads for each saga and avoid crashing for all sagas (and if all sagas are crashed - entire application is crashed). Wanted to hear more about best practices and usage of saga in complex application, but for intro to redux saga enough content provided in this course.
By Bennett Thompson on 12/3/2018
This course was explained quite quickly and efficiently. It's definitely an intro course to redux-saga though, so recommend you have a bit of experience with redux and using middleware if you want to take this course. Great for filling specifically a redux-saga knowledge gap.
