apollo-compiler@0.11.3

Features

• expose line/column location and JSON format from diagnostics, by goto-bus-stop in pull/668

  You can now use diagnostic.get_line_column() to access the line/column number where a validation error occurred.

  diagnostic.to_json() returns a GraphQL error structure that's serializable with serde, matching the JSON error format.

  let diagnostics = compiler.db.validate();
  let errors = diagnostics.into_iter().map(ApolloDiagnostic::to_json).collect::<Vec<_>>();
  
  let error_response = serde_json::to_string(&serde_json::json!({
      "errors": errors,
  }))?;

• improve validation error summaries, by goto-bus-stop in pull/674

  Adds more context and a more consistent voice to the "main" message for validation errors. They are now concise,
  matter-of-fact descriptions of the problem. Information about how to solve the problem is usually already provided
  by labels and notes on the diagnostic.

  • operation getName is defined multiple times
  • interface NamedEntity implements itself

  The primary use case for this is to make diagnostic.data.to_string() return a useful message for text-only error
  reports, like in JSON responses. The JSON format for diagnostics uses these new messages.
