GraphQL Mutation Example: Create a Post

Building a Mutation

GraphQL mutation creates a post with input object.

Introduction to GraphQL Mutations

GraphQL mutations are used to modify server-side data. Unlike queries, which only retrieve data, mutations can create, update, or delete data. In this tutorial, we will focus on creating a post using a GraphQL mutation with an input object.

Defining the Mutation

To perform a mutation, you need to define it in your GraphQL schema. For creating a post, we will define a mutation that accepts an input object containing the post's details like title, content, and author.

Implementing the Mutation Resolver

After defining the mutation in your schema, the next step is to implement the resolver function. This function will handle the actual creation of the post using the input data.

Executing the Mutation

To execute the mutation, you will need to send a mutation request to your GraphQL server. Below is an example of how to structure your mutation request to create a new post.

Conclusion and Next Steps

In this example, we walked through the process of setting up a GraphQL mutation to create a post. You defined a mutation in the schema, implemented a resolver, and executed the mutation with a request. For further learning, consider exploring GraphQL subscriptions to keep track of real-time data changes.
