Do not close your Strapi project while working on Vue.js. Dynamic zones are union types in graphql so you need to use fragments to query the fields. * This gives you an opportunity to extend code. As you can see, Strapi provides a highly flexible environment that can be used to create a fully functional content API in minutes. You can manually restart the server to make sure the GraphQL plugin is fully initializedyou can do this from the terminal as before: Once the server has restarted, you can test your new GraphQL API by opening the GraphQL playground: localhost:1337/graphql. Here we'll try something different with GraphQL, which we have done previously with the REST APIs - fetching content that depends on user authentication. For each model, the GraphQL plugin auto-generates queries and mutations that mimics basic CRUD operations (findMany, findOne, create, update, delete). Lets add a button for the delete functionality.

GraphQL APIs are inherently prone to security risks, such as credential leakage and denial of service attacks, that can be reduced by taking appropriate precautions. The authorization can be configured: Policies can be applied to a GraphQL resolver through the resolversConfig. A headless CMS is focused on storing and delivering structured contentit doesn't really care where and how the content is displayed. Hmm but how do I upload a single image to several fields in a single request? We need to create a new route and a new component for this and also edit the navigation bar once more. Set the playgroundAlways configuration option to true to also enable the GraphQL Playground in production environments (see plugins configuration documentation). A self-hosted and Enterprise-ready Edition. Adding new types, queries or mutations definitions in Strapi v4 is done through the use() method of the GraphQL extension service.

In either case, the operation is a simple string that a GraphQL server can parse and respond to with data in a specific format. The Strapi GraphQl playground is a development environment for you to interact with your Strapi application using GraphQl. v3/v4 Strapi GraphQl Resolvers Let's quickly review what each piece of our code in our custom resolver does.
