Printing Schema

Sometimes it's useful to have an SDL version of your schema. To do this, you can use some tools from the graphql package to write your schema out as SDL to a file.

import { writeFileSync } from 'fs';
import { printSchema, lexicographicSortSchema } from 'graphql';
import SchemaBuilder from '@giraphql/core';
const builder = new SchemaBuilder();
builder.queryType({
fields: (t) => ({
hello: t.string({
args: {
name: t.arg.string({}),
},
resolve: (parent, { name }) => `hello, ${name || 'World'}`,
}),
}),
});
const schema = builder.toSchema({});
const schemaAsString = printSchema(lexicographicSortSchema(exampleSchema));
writeFileSync('/path/to/schema.graphql', schema);
