beforeCreate helpers provide convenient functions and Components that make it easier to configure your Prefabs with the beforeCreate pop-up. For a basic explanation of beforeCreate check this page.

The following props are available inside the beforeCreate component:

Contents

prefab

An object which contains the original prefab.

save

A function that accepts a (mutated) prefab as an argument. When called the beforeCreate pop-up will close and the prefab will be added to the canvas.

close

A function which closes the pop-up and prevents the prefab from being dropped on the canvas when called.

components

A collection of components we made available for you to use. The components help to keep to the Betty Blocks style guide and give read access to metadata. Here is a list in alphabetical order containing every component we expose, their API, and an example on how to use them:

helpers

camelToSnakecase

This is a helper to convert camelCase to snake_case this is used for generating variables from the beforeCreate based on models. Will lowercase all characters and replace spaces with underscores. You can use this helper like this:

camelToSnakeCase("Test String")
// will return: "test_string"

useCurrentPageId

This helper will retrieve the UUID of the current page. If there is no UUID available it will return an empty string. You can use the helper like this:

beforeCreate: ({
  // extract other components if needed
  helpers: { useCurrentPageId }
}
const pageUuid = useCurrentPageId();

useModelQuery

Sometimes you need more information from a model than just the id (e.g. all the properties for a given model), this is where you can use useModelQuery. It works much in the same way as a useQuery from apollo does.

You can either use the onCompleted hook in the modelQuery to set your state.

useModelQuery({
  variables: { id: modelId },
  skip: !modelId,
  onCompleted: data => {
    // use data here
  },
});

Or you can use it more traditionally and destruct the objects from the query call.

const { data, loading, error } = useModelQuery({
  variables: { id: modelId },
  skip: !modelId,
});
