Phases of Execution

When GraphQL receives a query string, it goes through these steps:

• Tokenize: {{ "GraphQL::Language::Lexer" | api_doc }} splits the string into a stream of tokens
• Parse: {{ "GraphQL::Language::Parser" | api_doc }} builds an abstract syntax tree (AST) out of the stream of tokens
• Validate: {{ "GraphQL::StaticValidation::Validator" | api_doc }} validates the incoming AST as a valid query for the schema
• Analyze: If there are any query analyzers, they are run with {{ "GraphQL::Analysis.analyze_query" | api_doc }}
• Execute: The query is traversed, resolve functions are called and the response is built
• Respond: The response is returned as a {{ "GraphQL::Query::Result" | api_doc }}
