I’m trying to do a basic GraphQL query to a Shopify store with Sinatra. Could someone help me figure out what I’m doing wrong? I looked at their API to do this:
require 'shopify_api'
require 'sinatra'
class App < Sinatra::Base
get '/' do
shop = 'xxxx.myshopify.com'
token = 'shpat_xxxxxxxxxxxxxxxxxxxxxx'
session = ShopifyAPI::Session.new(domain: shop, token: token, api_version: "2021-04")
ShopifyAPI::Base.activate_session(session)
ShopifyAPI::GraphQL.initialize_clients
client = ShopifyAPI::GraphQL.client
SHOP_NAME_QUERY = client.parse <<-'GRAPHQL'
{
shop {
name
}
}
GRAPHQL
result = client.query(SHOP_NAME_QUERY)
result.data.shop.name
end
end
Which gives this error but I don’t want to use Rake or Rails. Is it possible to do a GraphQL query to Shopify with Ruby?
ShopifyAPI::GraphQL::InvalidClient at /
Client for API version 2021-04 does not exist because no schema file exists at `shopify_graphql_schemas/2021-04.json`. To dump the schema file, use the `rake shopify_api:graphql:dump` task

As the error states, you need to first dump the schema (see this link: https://github.com/Shopify/shopify_api/blob/v9/docs/graphql.md#dump-the-schema).
Then you create a
shopify_graphql_schemas
directory in the same root as your ruby script, and put the generated JSON there.Like stated in the comments, this requires a
Rake
task, so you need to be usingRails
.If your project doesn’t use Rails, you need to do a quick workaround.
You create a temporary barebones Rails project, then generate the dump using that project (you can delete the project when you’re done with this).
It’s a bit hacky, but it’s the only thing I can see that would work.

You need to use something like this
