Pub build status

Parses GraphQL queries and schemas. Also includes a GraphQLVisitor class.

This library is merely a parser/visitor. Any sort of actual GraphQL API functionality must be implemented by you, or by a third-party package.

Angel framework users should consider package:angel_graphql as a dead-simple way to add GraphQL functionality to their servers.


Add graphql_parser as a dependency in your pubspec.yaml file:

  graphql_parser: ^1.0.0


The AST featured in this library is directly based off this ANTLR4 grammar created by Joseph T. McBride:

import 'package:graphql_parser/graphql_parser.dart';

doSomething(String text) {
  var tokens = scan(text);
  var parser = new Parser(tokens);
  // Parse the GraphQL document using recursive descent
  var doc = parser.parseDocument();
  // Do something with the parsed GraphQL document...
