How to Pass Multiple IDs to Apollo GraphQL in a Single Query

Working with Apollo GraphQL can often introduce challenges, especially when dealing with multiple IDs. If you've found yourself pondering how to effectively query multiple items by their IDs using Apollo, you're in the right place! This guide will guide you through a straightforward solution that will not only streamline your data fetching but also keep your code clean and efficient.

The Problem

When working with a GraphQL API, you may encounter scenarios where you need to retrieve multiple items based on their IDs. The question at hand is whether it's possible to pass multiple IDs to a useQuery hook in Apollo or if you need to execute separate queries for each ID. Here's a breakdown of the specific problem:

Current Scenario: You have a query that retrieves a DecorSheet based on a single ID.

Objective: Fetch two DecorSheet objects using their IDs 293164663883956749 and 293526016787218952 in a single query, and combine their data into one object for rendering in your component.

The Solution

Fortunately, Apollo GraphQL gives us a neat way to handle this situation by leveraging field aliases. Here’s a step-by-step breakdown of how you can achieve this effectively.

Step 1: Define the GraphQL Query with Aliases

Instead of querying for a single ID, you can adapt your query structure to include both IDs by using aliases. Here’s how you can structure your GraphQL query:

Step 2: Utilize the useQuery Hook

Now that you have your query defined to accept two IDs, the next step is to set up the useQuery hook correctly to pass the IDs. Here’s an example of how you can do that:

Step 3: Handle the Returned Data

When the Query resolves, you will receive an object with both firstDecorSheet and secondDecorSheet, which can be used in your component. You can access these objects directly like this:

Conclusion

Using Apollo GraphQL to fetch multiple IDs in a single query can vastly improve the efficiency of your application. By utilizing field aliases, you can easily customize your queries while maintaining clean and readable code. This method not only reduces the amount of data fetching but also helps you manage how data is displayed within your components effectively.

With this guide, you should be well equipped to handle instances where multiple IDs are required within your Apollo GraphQL applications. Happy coding!
