@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);

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();
