Copy/Paste/Execute in your Node REPL (or `meteor shell`) to create a method for converting an instance of `SimpleSchema` to a Graph QL Schema definition

SimpleSchema to GraphQL Schema Definition.js

.editor
var os = require("os");

function schemaToGraphQl(schema) {
  const definitions = Object.keys(schema._schema).map((name) => {
    const s = schema._schema[name];
    return [
      s.label && `  "${s.label}"`,
      `  ${name}: ${s.type.definitions[0].type.name}` // brittle
    ].filter(s => s).join(os.EOL)
  });

  console.log(`"auto-generated GraphQL schema (replace with a proper description)"`);
  console.log("type YourSchema implements Node {");
  console.log(definitions.join(os.EOL.repeat(2)));
  console.log("}");

  return "if running Meteor/Reaction, check the terminal window where your server is running for the output"
};

`generate GraphQL schema with: ${schemaToGraphQl.name}(YourSchema)`
// ^D to execute
