GraphQL in Lightning Web Component

GraphQL is a query language for APIs that provides a flexible and efficient way to retrieve data from a server. It allows clients to request only the data they need, making it a great choice for building fast and responsive web applications.

When to use GraphQL Wire Adapter

  • GraphQL wire adapter provides a flexible and efficient way to retrieve data from a server using a single endpoint and query language.

  • GraphQL wire adapter is useful for optimizing apps with bandwidth and speed constraints, querying exact objects and fields, and paginating large data sets.

  • GraphQL wire adapter requires setting up a GraphQL server and sending queries to it using fetch or a library like Apollo Client.

  • LWC also provides other ways to work with Salesforce records, such as Lightning Data Service (LDS) wire adapters, lightning-*-form base components, and Apex.

  • LDS wire adapters are the only way to create, edit, or delete records, but they can require multiple round trips and adapters to request data.

  • Other LDS adapters can retrieve record data by Ids, but they cannot express complex filtering, sorting, and relationship traversals like GraphQL.

  • Apex can work with multiple records in a single transaction and run in system context without user permissions, sharing rules, or field-level security.

Using GraphQL in LWC Components

To use GraphQL in our LWC components, we need to send queries to the server and handle the responses. This can be done using the fetch API or a library like Apollo Client.

Here’s an example of how to send a query:
