Learn GraphQL In 40 Minutes

GraphQL is the hottest technology when it comes to server side APIs for good reason. It is incredibly fast to develop with, and it makes building a front-end painlessly easy. In this video I am going to be teaching you what GraphQL is, why it is important, why it is better than REST, and then we will be walking through an entire Node.js and Express GraphQL API for books and authors. By the end of this video you will have a complete understanding of what GraphQL is and how to use it.

I really enjoyed making this GraphQL video, and would love to make more videos about learning a single topic in one video. Let me know if you have any topics that you would want me to cover in a similiar manner.

[@AshishKumar-oe5ly]

thanks for making such a wonderful video on graph QL. Could you please make some tutorial on integrating GraphQL with Sails-Mongo application?

[@johnblyberg4801]

Your videos are fantastic because you get right in to it and provide great, real-world applications for the code you're writing. Thank you! My request would be a video or a series of videos on securing your API with JWT and other approaches for authentication, CSRF protection, etc. Thanks!

[@WebDevSimplified]

Thank you for the suggestions. JWT is a topic I want to cover in the nearish future.

[@StephanDuToit]

Web Dev Simplified hi there, have you been able to create this tut yet? Love your tutorials!

[@sundeepparuchuru]

Can you please make tutorial on apollo server with node js. Couldn't able to find much on web.

[@txdba]

The clarity of your voice is amazing. I'm 60 years old and don't hear well and it is rare I hear speech readily. Concerning the tool, the required prep is huge. This tool is a gift for contractors that charge by the hour if it is meant to be a replacement for SQL. It seems to be much more that SQL. Pardon my comparison to SQL, but it has been and still is the query tool of my career. Thank you.

[@JuanGutierrez-qg4zr]

All these channel videos are gems. By the way, if somebody else is facing the error "TypeError: expressGraphQL is not a function" just replace the import from const expressGraphQL = require("express-graphql"); to const { graphqlHTTP } = require("express-graphql");

[@FalseDev]

Great help, using typescript would have saved some time, and it's because they've make some breaking changes

[@sahelee1]

yes. alternatively : const expressGraphQL = require('express-graphql').graphqlHTTP require('express-graphql') returns an object with a property called graphqlHTTP that is the function you want to call.

[@ziyoshams]

This is excellent. I usually see others jumping right into Apollo, which has lots of abstraction. But this tutorial shows more lower level hands on approach of graphQL.

[@abhishek_k7]

Thank you for this amazing GraphQL tutorial!

[@SmartShorts4You]

A great brief tutorial, I think I fell in love with GraphQL now, thank you!

[@CliffordFajardo]

Really awesome introduction. The setup of an in memory datastore was great as it made learning the concepts easier. A lot people fail to mention that one of the big costs of GraphQL is for backend engineers, not the UI engineers querying the data though 😃 Still a good technology to be aware of.

[@WebDevSimplified]

Thank you so much. I'm glad you appreciated the in memory storage since a lot of people complain that makes the video useless when I feel that adding in a full db makes the video way too long.

[@volodymyrmatselyukh8808]

I can see the one drawback of GraphQL. While being efficient in terms of clientserver bandwidth it's inefficient in terms of serverdatabase bandwidth. With GraphQL you either return every single property from the database to a server and then server does filtering or, I think, there should be some libraries that move that filtering logic to a database side. The second approach would be a way efficient in terms of a database load. So, using JSON objects in this video is great but doesn't make accent on the challenge with serverdatabase communication.

[@MohitGupta-ln2js]

Decided to pick GraphQL for my next project and hence decided to learn it properly. After watching this video, it feels I already know a lot about it. Thanks for giving me such a quick start.

@@WebDevSimplified The bootcamp was a great experience, I've been doing web development since high school so I had a background in it prior to starting it. Everything came pretty quickly to me and I was able to easily understand the advanced concepts easier having had that prior experience. However, alot of others had no experience and the advance concepts where too hard for some people to grasp. I tried my best to get there before class and stay after class to tutor people though. Overall, it was a way for me to figure out the best path and what to learn in order to become employee ready.
