Develop Your GraphQL API with Apollo ExplorerĪpollo Explorer is a free cloud GraphQL IDE that we built from the ground up, specifically for GraphQL developers. You should be all set to implement filtering in your own GraphQL API. We just walked through a few examples of how to add filter functionality to your GraphQL API.

Filtering for a specific itemĬonsider the following GraphQL schema: type Query This means that you can use whatever database technology you like to fetch and save data for instance - SQL, ORMs, NoSQL, JSON, or in-memory data all work just fine.įor these examples, we’ll assume we’ve stored the data in-memory. For the rest of this post, we’ll use the word filter instead of search.įor each filtering example, we’ll take a look at the originating schema, how to write a query within it, and a resolver implementation.Īs a reminder, GraphQL is data source-agnostic. The goal is to find an item (or a list of items) that matches some sort of criteria. Searching is filtering: Searching and filtering are two different ways to say the same thing. To learn how to handle searching and filtering on the front-end using Apollo Client, read “ How to Filter and Search using Variables in Apollo Client“. In this article, we’ll learn how to add filtering capabilities to your API by walking through a few real-world examples. Searching and filtering is a standard part of any GraphQL API. ![]()
