I was working on a project which involved lots of REST API calls, and I decided to use to handle that. The library no doubt is really amazing but there lot of boiler plate(redundant) code with all those dispatches and all which really increases the size of the project and with increase in complexity it really becomes hard to tackle and manage React, Redux redux-thunk My project is growing at really pace and I can see code getting more redundant with more and more usage of . So I decided to try redux-saga over this weekend and I am pretty amazed by the results. redux-thunk First, to understand you need to understand how work in Javascript. I had used them earlier in python so I was aware of how they work but if you don’t have any idea of generators, do them out from and then proceed. Without a good understanding of generators you won’t get how works. redux-saga Generators here redux-saga To compare redux-thunk and redux-saga, I decided to create a small project which fetches a data from a remote API, updates the local store and my component reads from that store and shows it on the page. Being a fan I used the open API of star wars as the end point. star-wars Now coming to the project, we need to create to create actions, reducers and store for both redux-thunk and redux-saga. So in terms of configuration, pretty much entire code is same. Just the action part in redux-saga becomes really simple when generators kick in making redundant code of dispatches obsolete. Here are the actions from both redux-thunk and redux-saga:- Now if you see we are able to pass the promises to redux-saga middleware and it handles it automatically. This is something I was looking forward to because it does not involved dispatch and redundancy of code goes down drastically. You can check the code for redux-thunk and redux-saga with these links:- redux-thunk — https://github.com/jinxac/redux-thunk-saga/tree/ba7e60bdfe1a5e689de117ed095782ec22ff322d redux-saga — https://github.com/jinxac/redux-thunk-saga/tree/6d85f28a41af2cef1c9af6da259b88962a082bb5 I am really convinced that redux-saga is better way of handling REST calls in react project if your project is about to scale or already at that level. I am planning to move my projects from redux-thunk to redux-saga. If you liked the article you can follow me at / . github twitter
