Thanks! I used it to make this

@craigbeck

Thank you for your nice gist.

According to graphql-js issue #1429, graphql-js v14 dropped support onOperation, onFragment and onFields fields of directives.

This IntrospectionQuery is invalid for GraphQL API using v14 or later.

Instead of above fields, we should use the locations field.

query IntrospectionQuery {
  __schema {
    queryType {
      name
    }
    mutationType {
      name
    }
    subscriptionType {
      name
    }
    types {
      ...FullType
    }
    directives {
      name
      description
      args {
        ...InputValue
      }
-      onOperation
-      onField
-      onFragment
+     locations
    }
  }
}

I was looking for the following when I came across this gist:
https://graphql.org/graphql-js/utilities/#introspectionquery

const {introspectionQuery } = require('graphql');

@danstarns what is the query here?

@danstarns what is the query here?

introspectionQuery is an exported member of graphql, the query is that.

const { introspectionQuery } = require("graphql");

console.log(introspectionQuery);

@danstarns thank you.

The graphql reference implementation on JS has changed slightly and introspectionQuery is no longer exported as above. For newer versions of graphql (after graphql/graphql-js#2718), the above will break/not work, however, this seems to work after adapting to getIntrospectionQuery:

const path = require("path");
const fs = require("fs");
const fetch = require("node-fetch");
const {
    getIntrospectionQuery,
    printSchema,
    buildClientSchema
} = require("graphql");

async function main() {
  const introspectionQuery = getIntrospectionQuery();

    const response = await fetch(
        "https://<URL_HERE>/graphql",
        {
            method: "POST",
            headers: {
                "Content-Type": "application/json"
            },
            body: JSON.stringify({ query: introspectionQuery })
        }
    );

    const { data } = await response.json();

    const schema = buildClientSchema(data);

    const outputFile = path.join(__dirname, "./result.gql");

    await fs.promises.writeFile(outputFile, printSchema(schema));
}

main();

Good call updated getIntrospectionQuery 👍
