  1. To configure graphql plugin open the graphql tab at the bottom. Alt Text
  2. Press the '+' icon in the tab, select where you have to place the config file. Usually place at project root folder. (you will see some errors in schema errors section in graphql tab, ignore it for now)
  3. Now paste the content in generated .graphqlconfig file change $BASE_URL with your magento base url
  "name": "Practice GraphQL Schema",
  "schemaPath": "schema.graphql",
  "excludes": ["dev/**"],
  "extensions": {
    "endpoints": {
      "Default GraphQL Endpoint": {
        "url": "$BASE_URL/graphql",
        "headers": {
          "user-agent": "JS GraphQL"
        "introspect": true
Enter fullscreen mode Exit fullscreen mode
  1. Now refresh your graphql tab until your graphql endpoint shows up there. Double click it, and a popup ask you to select Endpoint action.
  2. Select Get Graphql Schema from Endpoint option.
  3. Now schema.graphql file will be generated in project root.

Now auto complete will be available for schema, query and mutation.

Fix schema errors in graphql tab.

  • The graphql custom directives by magento are not present in generated schema.
    Copy all the directives from vendor/magento/module-graph-ql\etc\schema.graphqls file to the top of generated schema.graphql file

  • Now you can see series of FilterTypeInput error followed by Unexpected Token: "null" error.
    If you fix this error, all FilterTypeInput errors will be removed.
    So easy fix remove it, you wont get auto complete for null filter in FilterTypeInput.

"Is null"
null: String 
Enter fullscreen mode Exit fullscreen mode

Find input FilterTypeInput and remove these two lines.


Whenever you update your schema. You have to update your generated schema.graphql file by repeating step 5 and fix these errors again.
