GraphQL

---

Magento has an excellent GraphQL implementation which gives you more flexibility over the REST API. Rapidez provides some handy renderless GraphQL Vue components to communicate with GraphQL.

Examples

See the usage within the Rapidez Repositories

• Query
  • Props
  • Slot scopes
• Mutation

  • Slot scopes

Query

<graphql> component example to get a list of available countries from Magento:

<graphql v-cloak query="{ countries { full_name_locale } }">
    <ul v-if="data" slot-scope="{ data }">
        <li v-for="country in data.countries">@{{ country.full_name_locale }}</li>                
    </ul>
</graphql>

Props

Prop	Type	Default	Explanation
query	String	Required	GraphQL query
variables	Object	{}	GraphQL variables
check	String		Run a check on the response data, for example: check="data.countries[0] == 'Country'"
redirect	String		Where to redirect if the check fails
cache	String		Cache key in localstorage. Caches only when provided and will be prefixed with graphql_. Will be flushed when the cache is cleared.
callback	Function		Called after the query

TIP

With large GraphQL queries you can extract the query to a separated file, for example: resources/views/queries/countries.graphql and include it with: query='@include('queries.countries')'

Slot scopes

Prop	Type	Explanation
data	Object	The data returned from the GraphQL request

Mutation

<graphql-mutation> component example with a newsletter subscription form:

<graphql-mutation v-cloak query="mutation visitor ($email: String!) { subscribeEmailToNewsletter(email: $email) { status } }" :alert="false" :clear="true">
    <div slot-scope="{ mutate, variables, mutated, error }">
        <strong v-if="mutated">
            @lang('Thank you for subscribing!')
        </strong>
        <div v-else>
            <form v-on:submit.prevent="mutate">
                <x-rapidez::input name="email" type="email" v-model="variables.email"/>
                <x-rapidez::button type="submit">
                    @lang('Subscribe')
                </x-rapidez::button>
            </form>
            <p v-if="error">
                @{{ error }}
            </p>
        </div>
    </div>
</graphql-mutation>

Props

Prop	Type	Default	Explanation

watch	Boolean	true	Should the variables be watched?
redirect	String		The redirect url
alert	Boolean	true	Show an alert when an error occurs
clear	Boolean	false	Clear the values after the mutation
before-request	Function(query, variables, options): [query, variables, options]		Called before the request is sent in order to change, must return [query, variables, options] if used
callback	Function		Called after the mutation
mutate-event	String		Event name to listen to, used to trigger the mutate method
recaptcha	Boolean	false	Sends the X-ReCaptcha header with the request

Slot scopes

Slot scopes are useful when wanting to get or update values or functions within the components template.

mutated	Boolean	True if the mutation has run
error	String	The error message if the GraphQL request failed
