@omnigraph/json-schema/esm/getGraphQLSchemaFromDereferencedJSONSchema.js

This package generates GraphQL Schema from JSON Schema and sample JSON request and responses. You can define your root field endpoints like below in your GraphQL Config for example;

import { specifiedDirectives } from 'graphql';
import { SchemaComposer } from 'graphql-compose';
import { addExecutionDirectivesToComposer, } from './addExecutionLogicToComposer.js';
import { getComposerFromJSONSchema } from './getComposerFromJSONSchema.js';
export async function getGraphQLSchemaFromDereferencedJSONSchema(name, opts) {
    const { fullyDeferencedSchema, logger, operations, operationHeaders, endpoint, queryParams, queryStringOptions, } = opts;
    logger.debug(`Generating GraphQL Schema from the bundled JSON Schema`);
    const visitorResult = await getComposerFromJSONSchema(fullyDeferencedSchema, logger.child('getComposerFromJSONSchema'));
    const schemaComposerWithoutExecutionLogic = visitorResult.output;
    if (!(schemaComposerWithoutExecutionLogic instanceof SchemaComposer)) {
        throw new Error('The visitor result should be a SchemaComposer instance.');
    }
    // graphql-compose doesn't add @defer and @stream to the schema
    for (const directive of specifiedDirectives) {
        schemaComposerWithoutExecutionLogic.addDirective(directive);
    }
    const schemaComposerWithExecutionLogic = await addExecutionDirectivesToComposer(name, {
        schemaComposer: schemaComposerWithoutExecutionLogic,
        logger,
        operations,
        operationHeaders,
        endpoint,
        queryParams,
        queryStringOptions,
    });
    if (schemaComposerWithExecutionLogic.Query.getFieldNames().length === 0) {
        schemaComposerWithExecutionLogic.Query.addFields({
            dummy: {
                type: 'String',
                resolve: () => 'dummy',
            },
        });
    }
    return schemaComposerWithExecutionLogic.buildSchema();
}
