Introduction
GraphQL is a query language for APIs, and it’s gaining popularity in the developer community.
GraphQL is an interesting alternative to RESTful APIs. It’s a straightforward way to create a single unified interface between your app and all of its data sources. In this article, we’ll go over some of the advantages of using GraphQL over other web development technologies like REST or SOAP services. We’ll look at why GraphQL is better than the rest and explore how you can use GraphQL with various languages/platforms: JavaScript, Python (and other languages), Java, and other platforms
GraphQL is the better REST
GraphQL is a way to access data. It’s a new way of getting exactly what you need, and it’s better than REST.
GraphQL is not just another format for fetching data; it offers more control over how the data gets fetched and returned (which can vary depending on what your app does). For example, if you need all of your user’s email addresses, then using GraphQL will let you create a query like this:
input { users(name: “John Doe”) { email } } output { emails() }
This assumes that there are multiple fields in our database called “users” that contain information about each user’s name and email address. You could also use [object] instead of {} for this field type if there was only one field like this one instead of many different ones across multiple tables in the database schema (e.g., [“user_id”, “email”]).
Over fetching and under fetching
The problem of over fetching is when you have too many resources and queries return some data that doesn’t need to be returned. For example, if you have a lot of users and are requesting the count for each user by ID, then it makes sense to fetch all the IDs first so that they can be used in the following query. However, if there are only 10 users but you request 100 IDs from them, then there will be an excessive amount of data being sent back from your API server—and this could cause issues with latency or network bandwidth utilization.
On the other hand, under-fetching occurs when there are not enough resources available to satisfy all requests; this happens because GraphQL APIs offer pagination support which allows them to return only partial results when requested by clients (rather than returning everything at once).
Strongly typed – with SDL
Strongly typed means that the client knows exactly what data it is getting from the server. With strongly typed, you can be more specific in your queries and write easier-to-maintain code.
GraphQL provides a type system for your component classes, allowing you to specify exactly what types are being used on both ends of your API connection. This makes it possible for clients and servers to communicate with each other clearly and effectively, eliminating any ambiguity about how they should communicate with one another (and thus avoiding problems related to over-fetching or under-fetching).
With SDL combined with GraphQL, there’s no need for manually writing code when working with underlying data structures – SDL handles all this automatically based on how we structure our query statements through the use of its automatically generated schema definitions!
Easy to write and read
Writing and reading your API is easier.
GraphQL’s schema is a type system that allows you to describe your data in a declarative way, eliminating the need for code-based descriptions. This makes it easier to write and read your API because there are no messy APIs with nested if statements or impenetrable JSON parameters.
It’s also easier to maintain: You can use GraphQL schema definitions instead of having to constantly change code every time you want to add or remove fields from an endpoint. And if something goes wrong, it will be easy (and fast) for developers on both sides of the wire—the client side as well as on servers responding back at any given time—to debug problems when they arise by looking at what changed since last run time (or even earlier).
Made by Facebook
Facebook is the creator of GraphQL and has been using it in production since 2015. Facebook also runs a large number of open-source projects, which have a good reputation among developers. As a result, Facebook’s engineering department has a lot of experience with APIs and can help you get started with GraphQL quickly by providing sample code or documentation that will help you learn how to use it effectively.
Multi-platform – you can use it with a lot of different languages/platforms.

GraphQL is strongly typed and has a comprehensive set of features that make it much easier to write, read and maintain code than REST. GraphQL was developed by Facebook and is used in production at scale across its many platforms including mobile apps, websites, APIs, and tools.
GraphQL allows you to define queries (request) & mutations (response) using strongly typed types such as strings or integers instead of having to manually check data types before sending them over the wire – avoiding potential errors caused by incorrect inputs being sent over HTTP requests which could also lead to denial-of-service attacks if there weren’t any checks made beforehand either!
GraphQL is an interesting alternative to RESTful APIs.
GraphQL is an interesting alternative to RESTful APIs. It’s a query language for APIs, similar to how SQL works for relational databases.
It’s not a replacement for RESTful APIs, but it allows you to query only the data that you need from an API and then return that information as one response. The main difference between GraphQL and traditional RESTful APIs is that in order for your client application or website to get all of its data from an API, it must send multiple requests back and forth between servers until everything has been retrieved; whereas, with GraphQL, no extra calls are necessary because all queries always return results directly within one request – which means less load on both sides!
Conclusion
GraphQL is a different API for a different time. It’s not going to replace REST in the future, but if you want to be a part of that future then GraphQL might work for you.
