There’s no denying that GraphQL is the latest addition for API development. For front end frameworks many GraphQL clients are available and Apollo is one of the most popular ones in Angular applications. In this article we are going to discuss about GraphQL and it’s integration with Angular. We will also take a closer look at the drawbacks of traditional GraphQL, and focus on Apollo integration and custom way of integrations.
Angular is open source web application framework managed by Angular Team at Google. For client side; it uses MVC (model-view-controller) and MVVM (model-view-view-model) architecture. Angular uses two ways data binding and automatic synchronization of data between Model and View. Stable version of Angular was 10.1 and licensed under MIT License.
GraphQL is open source data query and manipulation language. Facebook has developed it internally and released publicly in 2015.GraphQL provides an approach to develop web API compared to REST & other web architecture.It allows to define data structure as per the need and same structure can be used to manage the data returned from the server. Also, it consists of type system, query language and execution of semantic, static validation and type introspection.
Apollo client is management library which manage local data and remote data with GraphQL. It fetches, modify the application data and accordingly update the application UI. Apollo present all the data in such a way that you can easily browse the data and information and can join data across multiple resources to get the desired result.
Apollo team is struggling with maintaining eco-system. Apollo team has abandoned Redux as their internal state management solution. Team has not opinionated about how Redux should be used along with new updates. Many users don’t have much idea about how to proceed further with Apollo 2.0.
GraphQL encounters performance issue if client asks for too many fields in single instance so in this case – it might be worth using REST API to perform complex queries.
Apollo is in very early stage and whole Apollo team is working on the system and built it around the GraphQL eco-system. Advanced level of caching and monitoring system still in development. There are infrequent changes that can challenge the current updates and development when you update GraphQL library. In distinction – some of the libraries in GraphQL might be more conservative than Apollo. Ability of developers constant learning and facing challenges is really required.
As GraphQL is not understanding files, file uploading feature is not included into its specification. In case of REST API – you won’t deal with such type of scenario as you can just put POST and can set the functionality
GraphQL is right solution for multiple microservices; but in case of small application – it’s better to adopt REST API architecture. REST can also be good approach when you connect resource driven apps which don’t need queries offered by GraphQL
We have implemented our customize cache-service to store data.
Our way to integrate graphQL with Angular
Apollo Angular thus allows you to fetch data from GraphQL and use it in building reactive UIs through the Angular framework. GraphQL is maturing and we will see further adoption and support for it in the .NET ecosystem. We have just scratched the basic of Apollo client – it has much more to offer. Apollo offers extensive options for fine tuning the caches and loading mechanisms as well. Apollo client for Angular provides a simple yet strong library for integrating your app with any GraphQL server.
