GraphQL for APIs
Explore how GraphQL APIs provide a more flexible and efficient alternative to REST APIs by enabling precise data queries using schemas and resolvers. Understand key components like schemas, mutations, and queries, and how they integrate with AWS serverless tools to optimize API data fetching.
We'll cover the following...
GraphQL is a query language for APIs and runtime used to execute the queries on existing data. It allows us to precisely describe the shape of the data that should be queried and defines a schema for it.
A GraphQL API uses the GraphQL query language to enable clients to interact with the server and receive responses tailored to their needs. GraphQL APIs provide a more flexible alternative to traditional RESTful APIs
GraphQL API vs. REST API
Let’s compare GraphQL API with REST API. Consider a news website as a web application with multiple sections on the front page, as shown in the illustration below, each for headlines, weather updates, and featured articles. Each section might have a different data source. A RESTful API will create a separate endpoint for each data source and call multiple endpoints simultaneously, adding to the network latency. To resolve this issue, GraphQL API combines the calls to multiple data ...
