Git is a very wonderful and revision management system as we all developer know it. Git has itself an advance level bus architecture. Today Git is very useful for every IT industries they are using it very frequently. But still Git has hold many hidden features, which we have not know yet. So today I am going to share one of them.It is Upstream and Downstream. Before trying to understand what...
Here I have picked one of most interesting topic for API development. From many year, we are developing an API in two Protocols REST and SOAP and most of time developers are preferred REST, because of its simplicity and easy to handle in APPS’. But last many days I have seen a new Query language with more simple and fast as compared to REST and it is graphical query lang.(GraphQL).
GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. 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?
GraphQL is an application layer query language that interprets a string by a server, which then returns the required data in a specified format. Open sourced by Facebook in 2015, GraphQL was developed internally during the transition from Facebook’s HTML5-powered mobile apps to native apps. Today it is the principle graph data query language powering the majority of interactions within iOS and Facebook Android applications. Anyone that has used native iOS or Android apps during the past two years has used GraphQL-powered apps.
The creators of GraphQL plan to open-source an instruction program on how to implement the server. The goal is to expand GraphQL capabilities to adapt to a wide range of backends. This will allow coders to use the technology in projects of any size to access their own data more efficiently. Product developers will be able to structure servers and provide powerful frameworks, abstractions and tools.
What You Can Do With GraphQL
GraphQL is a very liberating platform. With GraphQL, product developers no longer need to contend with ad hoc endpoints or worry about accessing data with multiple roundtrip object retrievals. Instead, you can easily create an elegant, declarative-hierarchical query dispatched to one single endpoint. You no longer have to jump back and forth from client to server development environments to test new codes or to create views of data already entered. Now all your experimentation and newly created views are built exclusively in the client development environment. The hassle of moving unstructured data from ad hoc endpoints into business objects is eliminated. Instead, you get a powerful, intuitive type system you can use as a tool-building platform.
How GraphQL Is Different
The GraphQL query language is positioned between client applications and the actual data sources. Think of it as a type of agreement between the client and the server with an efficient query and fetching system. It works independently from data sources and other platforms. A GraphQL server can be created in PHP, Node or any other platform of your choice. People should be able to connect to your GraphQL server with web apps, mobile apps or any other type of apps they may be using. They can then query and mutate the data they are looking for.
It has very interesting feature and I have mentioned the list.
get exactly thatSend a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server.
in a single requestGraphQL queries access not just the properties of one resource but also smoothly follow references between them. While typical REST APIs require loading from multiple URLs, GraphQL APIs get all the data your app needs in a single request. Apps using GraphQL can be quick even on slow mobile network connections.
with a type systemGraphQL APIs are organized in terms of types and fields, not endpoints. Access the full capabilities of your data from a single endpoint. GraphQL uses types to ensure Apps only ask for what’s possible and provide clear and helpful errors. Apps can use types to avoid writing manual parsing code.
without versionsAdd new fields and types to your GraphQL API without impacting existing queries. Aging fields can be deprecated and hidden from tools. By using a single evolving version, GraphQL APIs give apps continuous access to new features and encourage cleaner, more maintainable server code.
