Build Schema from JSON introspection query

[ruudk]

Is it possible to build a schema from a JSON introspection query using https://webonyx.github.io/graphql-php/schema-definition-language/?

This doesn't work:

<?php
use GraphQL\Utils\BuildSchema;

$contents = file_get_contents('schema.json');
$schema = BuildSchema::build($contents);

PHP Fatal error:  Uncaught Syntax Error: Expected Name, found String "data"

GraphQL request (1:2)
1: {"data":{"__schema":{"queryType":{"name":"Query"}...

Why? I want to parse the schema of an external GraphQL backend using this library.

\GraphQL\Utils\BuildClientSchema::build(
    json_decode(file_get_contents('schema.json'), true)
);

Thank you 🙌 , this worked:

\GraphQL\Utils\BuildClientSchema::build(
    json_decode(file_get_contents('schema.json'), true)['data']
);

That is assuming you are directly saving the result of calling the introspection query to schema.json. I would recommend validating if it contains errors first, and only then picking data from it and save that to the file.

Will do, thank you @spawnia
