@magidoc/rollup-plugin-gql-schema/build/schema/query.js

A Rollup and ViteJS plugin that allows to parse a GraphQL Schema from a target URL and save it to a target output folder, or to parse it from the disk and convert it to a desired format.

        operationName: 'IntrospectionQuery',
        query: parameters.query ?? getIntrospectionQuery().trim(),
        variables: null,
    });
    return axios({

        method: actualMethod,
        headers: {
            'Content-Type': 'application/json',
