Using GraphQL
Explore how to integrate GraphQL APIs into a Vuex store for advanced state management in Vue applications. Learn to write GraphQL queries and mutations, utilize TypeScript for typing entities, and manage data efficiently with caching. This lesson helps you build scalable Vue apps that handle API data cleanly and performantly.
We'll cover the following...
GraphQL is an API standard that has taken the development world by storm. It allows apps to fetch only the necessary data and receive them as a graph. The GraphQL syntax has very little noise overall and is human-readable.
How GraphQL queries work
In short, GraphQL is a syntax to communicate with an API. It's agnostic from any server technology, and we can integrate it into existing applications and data structures. GraphQL knows two different kinds of operations—queries and mutations. We use queries to fetch data and mutations to alter it. For example, a query to fetch a list of posts with the title and body text would look like the widget below:
To prevent over-fetching, we can specify only the fields we need. GraphQL lets us do that. To fetch every post's author with the posts, we would alter the query, as illustrated below:
