From lines 2 to 5, this is where we require and import everything that we need to successfully create a GraphQL server that is in accordance with the structure that is in schema/ country.js.įrom lines 6 to 13, the variable CountryType is instantiated by GraphQLObjectType() method, which is coming from graphql. Now, back to what is happening in schema/schema.js. In your folder, create a file called “app.js” and paste the following code: //jsĬonst ,Īt the end, your project’s folder should look like this: Whenever we require a package, it looks at this folder. Note that when you installed these packages, it created the node_modules folder, where all the necessary files and dependencies are being stored.

We need graphql, because that is what we are building on and this package in itself provides us with all the methods needed - except that we want to run on an express.js server and, out of the box, express.js does not know how to communicate with graphql.īecause of this, we need another package express-graphql. Now let me explain what the following packages do. You should add "dev": "node app.js" to your script object in package.json file.Īfter they are all installed, your package.json file should look like this:

For that, run: npm install graphql express-graphql express. The next thing to do is to install the necessary packages that we need for our project. This will create a package.json file in the folder that you are in. Once you are in your newly created or desired folder, run this on your command-line interface (CLI): We are building an express.js server, which is a Node.js application - we will create a folder to house our project files.

A code editor (I use Visual Studio Code).We will be using express.js to spin up a server for this tutorial Understanding of basic express server setup.This comes with node package manager (npm) Prerequisitesīefore we go further, it is important that we note the knowledge required to better understand this topic: It’s a powerful tool a tool that helps you structure GraphQL queries visually. GraphiQL is the GraphQL integrated development environment (IDE).
Now, I want you to think of GraphiQL as Postman or Insomnia. Now, if you are familiar with RESTful APIs, you will probably be aware of tools like Postman and Insomnia, because not only do they help us with our API development in terms of visualizing things quickly, but they also help us get things done faster. GraphQL was developed internally by Facebook in 2012 before being released to the public in 2015.ĭevelopers tend to prefer it to the REpresentational State Transfer (REST) approach of interacting with APIs, but we will be careful not to fall into making this article about the pros and cons of the RESTful approach and GraphQL - we’ll leave that for another article. GraphQL is an open-source data query and manipulation language for application programming interfaces (API), and a runtime for fulfilling queries with existing data. Let’s jump right in!īefore we talk about GraphiQL, let talk about what it helps - GraphQL. In this tutorial, look at how to use GraphiQL to aid GraphQL development. You do not have to overcomplicate things, and besides, even geeks are tending to favor using a graphical user interface these days.
Yes, understanding how things work under the hood tends to have its benefits, but not always. Visualizing GraphQL schema with GraphiQLĭo you need to use the complicated method when there is a better and simpler alternative? Why always stick to command-line interfaces when doing the most basic things?
