@javinpaulJavin Paul I am Java programmer, blogger on http://javarevisited.blogspot.com and http://java67.com Hello guys, you might have heard about GraphQL, another exciting technology. GraphQL is gaining a lot of popularity because of its superiority over traditional REST APIs. Many big companies like Facebook, Coursera, GitHub, and Yelp have already started using it, which has also helped a lot in terms of gaining popularity. There is a good chance that you might have already have heard about GraphQL in blogs pots, on Medium, or, in general Web but like many others not sure whether it’s worth learning or not and if yes, from where to start. Well, I have been learning GraphQL since last week and I would like to share some of the resources I have been using for my learning. If you happen to learn GraphQL you can also get benefit from these tutorials and courses and if you happen to be a GraphQL expert, maybe you can advise if I am in the right direction or not. You can also suggest some of the great GraphQL resources which are not mentioned in this list and I should look. Anyway, before I go into which courses and tutorials to learn GraphQL in 2020, let me give you a brief overview of What is GraphQL and why should a web developer learn GraphQL. The GraphQL is nothing but a query language from Facebook which aims to solve pertinent problems with REST APIs like a lot of endpoints, under-fetching, and over-fetching of data, and versioning. It provides a wrapper around APIs which makes it easier from front-end to use a single endpoint to get all the things they need. For, example Github’s REST API for user data, https://api.github.com/users/returns User details which contains 31 fields, if you are just interested in id, location, and url then you are fetching a lot of unnecessary data which could impact performance and scalability of your application. GraphQL solves this problem by wrapping this API and providing a simpler interface based upon your requirement. It also makes it easier to evolve APIs over time and enables powerful developer tools. Once you start using GraphQL I am sure you will also start loving its flexibility, type-safety, and community of support. Because of these awesome qualities, GraphQL is getting more and more popular every passing day and who knows it may replace REST in the coming years. Many companies like Coursera have already use GraphQL for their API. They have also built tools that can dynamically translate their REST APIs to GraphQL. If these things excite you and you want to try GraphQL or explore more, you can check out the tutorials and courses, both free and paid, I am going to share with you now. There are so many GraphQL resources on the internet and its difficult to choose which one is the best, but, you don’t need to.
