GraphQL is a breath of fresh air in a world dominated by REST architecture. In order to be able to display the required information, the app will have to make one request to the /users endpoint and then hit the /users//followers endpoint for each user. Today we are going to compare GraphQL, a newly introduced tool for the API management, with the classical REST. Während aus der Freiheit bei der Datenabfrage von GraphQL einerseits viele positive Merkmale resultieren, kann sie andererseits jedoch auch zum ernsthaften Sicherheitsproblem werden: Vor allem, wenn Sie offene APIs anbieten wollen, bei denen Sie das Abfrageverhalten von Drittanbieter-Clients nicht kontrollieren können.

Letztere lassen sich durch die Caching-Methoden der HTTP-Spezifikation zwischenspeichern (beispielsweise im Browser). This is the reason why, in many cases, it is still considered the industry standard when it comes to deploying APIs. Die GraphQL-Serverinstanz liefert dabei exakt die in der Abfrage definierten Informationen aus, sodass weder mehr noch weniger Daten als benötigt über die Schnittstelle versendet werden.

This kills productivity and notably slows down the ability to incorporate user feedback into a product. The main GraphQL quality is being less loquacious than traditional REST API. RPC functions on contracts, the negotiation is defined by the relationship between the server and the client not by the architecture. GraphQL = performance vs REST = reliability. Let's just do a quick recap regarding the differences between REST and GraphQL: 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.

In this introductory blog and accompanying article, I compare and contrast two competing stacks, Express and JavaScript with Apollo and TypeScript. With a REST API, you would typically gather the data by accessing multiple endpoints. However, REST APIs have shown to be too inflexible to keep up with the rapidly changing requirements of the clients that access them. GraphQL provides a better learning curve as compared to REST. REST is used by many developers and is widely regarded as the traditional way to send data over HTTP, but this trend is changing with the increase of GraphQL popularity. 2015 machte Facebook den GraphQL-Quellcode frei verfügbar – zu diesem Zeitpunkt regelte er fast schon den gesamten Datenzugriff der mobilen Apps. endpoint and receive a JSON array with user data.

Öffnen Sie dazu einfach Ihren Browser und geben Sie die folgende Adresse ein: Nachdem Sie in den verschiedenen Schritten dieses GraphQL-Tutorials die notwendigen Komponenten installiert, Ihr erstes Abfrage-Schema erstellt und den eigenen Server gestartet haben, können Sie sich danach also in aller Ruhe mit den Query-Eingabemöglichkeiten vertraut machen. Wie so oft gibt es auch hierfür einige etablierte Standards wie SOAP oder REST (Representational State Transfer), die eine Grundstruktur für Ihr API vorgeben, die mit jeder gängigen Programmiersprache problemlos angesteuert werden kann – insbesondere letztgenannte Architektur hat sich aufgrund ihrer Simplizität in den vergangenen Jahren zur absoluten Premium-Lösung entwickelt. GraphQL vs REST. Of late, GraphQL has been presented as a revolutionary alternative to REST APIs—but as with anything else, it has its pros and cons.

Using GraphQL, the client can specify exactly the data it needs in a. of the server’s response follows precisely the nested structure defined in the query. This just means creating Phoenix controllers that … Angesichts der zunehmenden Popularität von GraphQL lohnt es sich aber, einen genaueren Blick darauf zu werfen und es gegebenenfalls für eigene Projekte in Betracht zu ziehen.
