GraphQL tutorial for beginners: learn to builds your own GraphQL API with JavaScript

Do you know what Facebook did when traditional REST API’s were not good enough to power their mobile applications? They created GraphQL! The more flexible and faster tool that you can learn to harness for your needs in this GraphQL tutorial. I’m inviting you to learn all that you need to know for building your own GraphQL API with JavaScript. Understand how it works and learn how to build API’s with this astounding tool! 

What are the reasons to take a GraphQL tutorial? 

GraphQL is a replacement of traditional REST API’s because of a few important advantages. When you learn GraphQL, with a single request sent to the server, you can query multiple resources. In other words, if you have data stored in the MySQL database, and then additional data stored in text files, a GraphQL API can read and combine them into a single response for your pleasure! GraphQL’s efficiency also lies in the fact that it returns only the data that you request, so the loading time is reduced, and on top of that, user experience becomes a lot better! For example, if you want to create a database for a social networking page, and your user wants nothing more but the list of his friends, your GraphQL API will provide their names. With other techniques, it’s challenging to implement such an approach, and in GraphQL case, it’s built-in by default! 

It’s easy to learn GraphQL API building. What I also like about it is its vast community. You can make use of uncountable templates in different programming languages, be it PHP, Node, Ruby, Python, JavaScript – no problem at all! Moreover, the community shares a lot of bindings and clients for different frameworks and coding languages. I can see no reason for not starting this GraphQL tutorial right at this second!
