What Exactly Is GraphQL?

What is the purpose of GraphQL?

GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools..

What is GraphQL database?

GraphQL is often confused with being a database technology. This is a misconception, GraphQL is a query language for APIs – not databases. In that sense it’s database agnostic and can be used with any kind of database or even no database at all.

Does GraphQL replace SQL?

GraphQL is an alternative to REST, not SQL. GraphQL is not SQL! Instead, GraphQL is data-agonistic, and GraphQL, being one of the possible and most popular way, uses SQL to fetch data.

What is GraphQL written in?

Is GraphQL frontend or backend?

GraphQL is a means for backend developers to design their APIs in an easy to use manner regardless of the front-end benefits.

Why you should not use GraphQL?

GraphQL will make some tasks more complex. It’s easier to use a web cache with REST than with GraphQL. You could have performance issues with GraphQL queries. The way GraphQL schemas work could be a problem.

Is GraphQL better than rest?

GraphQL reduces network requests by allowing us fetch or retrieve all the data we need in a single query. It is easy to fetch more than the data you need with REST, because each endpoint in a REST API has a fixed data structure which it is meant to return whenever it is hit.

Is GraphQL restful?

GraphQL follows the same set of constraints as REST APIs, but it organizes data into a graph using one interface. Objects are represented by nodes (defined using the GraphQL schema), and the relationship between nodes is represented by edges in the graph.

Is GraphQL the future?

The fact that GraphQL is an open source query language means that the community can contribute to it and make improvements to it.

Is GraphQL hard to learn?

A well-designed API is very easy to use and learn. It’s also intuitive, a good point to keep in mind when you’re starting to design your API. To solve these problems, Facebook created GraphQL. … Since GraphQL is open-source, its community has grown huge.

What is GraphQL and why use it?

GraphQL is a query language (that’s what the “QL” stands for) for APIs and a runtime for fulfilling those queries with your existing data. Basically, it is used to load data from a server to a client — it’s a way to get data from an API into your application.

Is GraphQL faster than rest?

GraphQL vs REST comparison GraphQL solves both over-fetching and under-fetching issues by allowing the client to request only the needed data; Since the client now has more freedom in the fetched data, development is much faster with GraphQL than what it would be with REST.

Is GraphQL JSON?

GraphQL services typically respond using JSON, however the GraphQL spec does not require it. … JSON is also very familiar to client and API developers, and is easy to read and debug. In fact, the GraphQL syntax is partly inspired by the JSON syntax.

Why is GraphQL bad?

GraphQL is famously bad at caching, mostly because the alternatives (REST and Falcor) make caching at all levels so easy and efficient. GraphQL is bad at sending anything other than text back and forth (such as file uploads) while REST APIs can do literally anything.

Is GraphQL server side or client side?

Although GraphQL is talked about a lot around the frontend API, the API itself is still implemented on the server side. And it allows the backend developer to focus on describing the data, rather than implementing and optimizing numerous REST endpoints.
