Help with Variables in a Graphql Request

[akatcha]

Hi Everyone,

I'm new to developing shopify apps and graphql.

I'm trying to query shopify's admin graphql, similar to this guide: https://shopify.dev/tutorials/build-a-shopify-app-with-node-and-react/fetch-data-with-apollo . For those unfamiliar, we are using Apollo Client in the front-end and proxying the request to the backend.

I have create the request I wanted in the shopify GraphiQL tool (see below).  I'm trying to request on all orders between two dates.

I'm trying to make the same request in my code (below).  However when the app loads I get this error: 

GraphQL error: Variable $startTime is declared by getOrders but not used GraphQL error: Variable $endTime is declared by getOrders but not used

Wondering if anyone knows how to make this request work and where are the best resources for help on this in the future?

There might be a way better way of fetching this data, so if you know of an easier way, I'd be intrigued to learn.

From a new shopify dev perspective: Shopify documentation is lacking when it comes to using graphql vs REST implementations, (ie when should I use one over the other, confusing).  Also, online I'm finding that the Apollo library I'm using (which is also used in the guide linked above) is deprecated https://www.apollographql.com/docs/react/api/react/components/ .  Not sure if this should be reflected in the guide 🙂

Thanks.

Hi @akatcha,

GraphQL doesn't allow you to use variables as part of a string within a query, so you won't be able to use $startTime and $endTime inside your query that way.

One possible solution for this would be to define your query as query getOrders($query: String!) and pass in a formed query created_at:>... created_at:<..., and build that query in your app code before going into GraphQL.

Also, thank you for your feedback on the guide, it's very helpful!

Hope this helps!
