Set up a WordPress site and get it running. Local by WP Engine<\/a> is a good dev environment to use.<\/p>\n\n\n\n 2.

Clone down the Nuxt repo<\/a> for this project by copying and pasting this command in your terminal:<\/p>\n\n\n <\/p>\n\n\n\n 4. Import the questionnaire form. From the WordPress admin sidebar, go to 5. Create a 6. Run 7. Run 8. You should now be able to click the \u201cQuestionnaire\u201d link in the header to go to the form at http:\/\/localhost:3000\/questionnaire<\/a> in a web browser and see it in all its glory:<\/p>\n\n\n\n The WPGraphQL for Gravity Forms plugin is a powerful extension for WPGraphQL that provides a comprehensive suite of features that allows developers to interact with Gravity Forms via GraphQL. Let\u2019s start by querying for a form.<\/p>\n\n\n\n To query for a form, we have the For that form, the query fetches basic information like its title and description.<\/p>\n\n\n\n The query also fetches the Go ahead and test out this query right from the WordPress admin by following these steps:<\/p>\n\n\n\n 1. Go to 2. Paste the query above into the left column, replacing 3. Click the \u25b6 button to execute the query.<\/p>\n\n\n\n 4. See the results returned in the right column. You should see this:<\/p>\n\n\n\n Now, let\u2019s highlight one of the latest features of WPGraphQL for Gravity Forms which we use in this project. This feature is Forms Field support<\/a> with the The interface approach leverages GraphQL interfaces to abstract shared properties among Gravity Forms fields, meaning you can query a common set of fields like This method allows you to write a more composable query that automatically includes any new field type that implements a given interface without needing to update your query.<\/p>\n\n\n\n In our project, we used inline fragments on interfaces such as Our query retrieves both For other use cases outside the scope of this article, you can leverage the This dynamic approach allows a single form field to resolve into multiple input types\u2014such as a Quiz Field that can be rendered as either a Checkbox or Radio Field\u2014based on its configuration.
