What is REST? 🏗️🧵 Image
REST (Representational State Transfer) is an architectural style for building web services and APIs.
In a RESTful architecture, resources are identified by URIs (Uniform Resource Identifiers), and operations are performed on those resources using standard HTTP methods such as GET, POST, PUT, and DELETE.
The state of a resource is represented in JSON or XML, which is transferred between the client and server in the HTTP request and response bodies.
One of the key principles of REST is the separation of concerns between the client and server.

The server is responsible for managing the resources and performing the requested operations, while the client is responsible for generating requests and interpreting the responses.
This allows for greater flexibility and modifiability, as changes to the server do not necessarily require changes to the client.
Here are some RESTful resources ⤵️

What is an API Gateway? 🌁🧵 Image
An API gateway is a server that acts as an entry point for clients to access and interact with multiple microservices and backend systems.
API gateways are an important component of microservice-based architectures, as they provide a centralized point of control for many common tasks that would otherwise be performed by each individual microservice.

What is an API client? 🛠️🧵 Image
An API client is a development tool that makes it easier for producers and consumers to explore, test, and debug APIs.
Traditional approaches to calling an API require a significant amount of specialized knowledge; for instance, the API user must know a programming language, understand the API's framework and protocol, and be able to interpret the response.

What is GraphQL? 👾🧵 Image
GraphQL is an open source query language for APIs that was created by Facebook in 2012.

With GraphQL, clients interact with a single endpoint and specify the exact data they need, without having to chain multiple requests together.
This approach reduces the number of round trips between the client and the server, which can improve performance—especially on slow or unreliable network connections.

What is a cache? 🧵⚙️ Image
A cache is an infrastructure component that temporarily stores frequently accessed data so that it can be served more quickly and efficiently.
When an API client makes a request, the server can check the cache to see if the requested data is already available.

If it is, the server can return the cached response directly to the client, without having to execute the full request again.
