Salesforce Spring ’26: How to Use GraphQL Mutations in Lightning Web Components (LWC)

Salesforce Spring ’26 introduces an exciting new capability for Lightning Web Components (LWC): GraphQL Mutations.

If you’ve been using LWC to display data, you’re likely familiar with @wire(graphql), which allows you to read data reactively. However, until now, creating, updating, or deleting records required Apex methods or REST API calls.

With GraphQL mutations, developers can now perform create, update, and delete operations directly from JavaScript in LWC, making data operations simpler and more efficient.

What Is a GraphQL Mutation?

In simple terms:

  • Query → Reads data
  • Mutation → Creates, updates, or deletes data

Think of it like this:

  • Queries = “Give me this data”
  • Mutations = “Change this data”

Salesforce Spring ’26 introduces a new function called executeMutation, which allows developers to perform these operations directly within Lightning Web Components.

How GraphQL Mutations Work in LWC

To use GraphQL mutations in LWC:

  1. Define your mutation using the gql template.
  2. Send it using executeMutation, along with the required values.
  3. Retrieve only the fields you request – avoiding unnecessary data.

This approach improves performance, efficiency, and developer productivity.

Step 1 – Import the Required Functions

First, import the required functions:

import { gql, executeMutation } from ‘lightning/graphql’;

  • gql allows you to write GraphQL queries or mutations.
  • executeMutation executes the mutation directly from your component.

Step 2 – Write a Simple Mutation

Here is an example of a GraphQL mutation to create a new Contact record.

Explanation

  • $input represents the data we send to create the Contact.
  • Record { Id, FirstName { value }, LastName { value } } specifies which fields we want Salesforce to return after the record is created.

This ensures the response includes only the necessary fields.

Step 3 – Execute the Mutation

const result = await executeMutation({
query: CREATE_CONTACT,
variables: {
input: {
Contact: {
FirstName: ‘Sam’,
LastName: ‘Smith’
}
}
}
});const newId = result.data.uiapi.ContactCreate.Record.Id;
console.log(‘Created Contact ID:’, newId);

What Happens Here

  1. We call executeMutation with the mutation query and variables.
  2. Salesforce creates the Contact record.
  3. The response returns the Contact ID, which can then be used inside the component.

Beginner-Friendly Example

Imagine you have a form in your Lightning Web Component that allows users to create a new Contact.

ContactForm.html
ContactForm.html
ContacttForm.js
ContactForm.js

Using GraphQL mutations, users can submit the form and instantly create a Contact record, all handled directly within LWC using GraphQL.

Conclusion

GraphQL Mutations in Lightning Web Components introduce a modern and efficient way to perform create, update, and delete operations directly from LWC. With the Spring ’26 release, developers can now manage data operations using GraphQL without relying heavily on Apex or REST APIs. By using executeMutation, LWC components become more streamlined, flexible, and easier to maintain. This enhancement helps developers build faster, cleaner, and more scalable Salesforce applications while simplifying client-side data management.
