Walkthrough

Adds a new GraphQL nursery lint rule useLoneAnonymousOperation that flags anonymous operations when a document contains more than one operation. Implements the rule logic, diagnostics (document-level and per-range notes), and a Rule implementation. Introduces UseLoneAnonymousOperationOptions, exports its module from crates/biome_rule_options, adds a patch changeset, and includes test fixtures covering valid and invalid scenarios.

🧹 Nitpick comments (2)
crates/biome_graphql_analyze/src/lint/nursery/use_lone_anonymous_operation.rs (2)

9-47: Consider adding issue_number field.

Per coding guidelines, work-in-progress rules in the nursery group should include an issue_number field in the declare_lint_rule! macro to track the associated issue. Based on learnings, add issue_number field to declare_lint_rule! macro for work-in-progress rules.

Suggested addition
 pub UseLoneAnonymousOperation {
     version: "next",
     name: "useLoneAnonymousOperation",
     language: "graphql",
     recommended: false,
+    issue_number: 8616,
     sources: &[RuleSource::EslintGraphql("lone-anonymous-operation").same()],
 }

Additionally, consider adding a valid example showing a single anonymous operation (which is allowed) to better illustrate when the rule doesn't trigger:

query {
  fieldA
}

103-131: Consider clarifying the diagnostic message.

The message "Document contains (multiple) anonymous operations" with "(multiple)" in parentheses is slightly ambiguous when only one anonymous operation exists alongside named operations. Consider:

  • "Document contains anonymous operation(s) alongside other operations"
  • Conditionally pluralising based on state.len()

However, the detail message on line 117 and the notes are clear and helpful, so this is a minor wording suggestion.

Learning: In the Biome codebase, each lint rule has its own options type declaration (e.g., `type Options = RuleNameOptions`) as part of the codegen process, even if the options struct is empty or unused. This is standard practice and should not be flagged as an issue.

Learning: When defining lint rules (declare_lint_rule!), only specify fix_kind if the rule implements an action(...) function. Rules that only emit diagnostics without a code fix should omit fix_kind. This applies to all Rust lint rule definitions under crates/.../src/lint (e.g., crates/biome_js_analyze/src/lint/...).

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/invalid/multi-shorthand.graphql (1)

1-7: LGTM!

Test case correctly exercises the rule with two shorthand anonymous operations. The GraphQL syntax is valid, and the diagnostic comment is appropriate.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/invalid/with-named-query.graphql (1)

1-7: LGTM!

Test case correctly exercises the rule with an anonymous operation alongside a named query. This validates the rule's detection of anonymous operations when other named operations are present.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/invalid/with-mutation.graphql (1)

1-7: LGTM!

Test case correctly exercises the rule with an anonymous query alongside a named mutation. This ensures the rule detects anonymous operations when mixed with different operation types.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/invalid/one-shorthand-one-anonymous.graphql (1)

1-7: LGTM!

Test case correctly exercises the rule with both shorthand and explicit anonymous operations. This ensures the rule detects multiple anonymous operations regardless of their syntax form.

.changeset/eleven-parents-divide.md (1)

1-17: LGTM!

Changeset correctly documents the new nursery rule with a clear description and appropriate invalid example. The documentation follows the standard format.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/valid/one-anonymous.graphql (1)

1-4: LGTM!

Test case correctly validates that a single anonymous operation should not trigger diagnostics. This is the core valid scenario for the rule.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/valid/with-type.graphql (1)

1-7: LGTM!

Test case correctly validates that an anonymous operation with fragment definitions should not trigger diagnostics. Fragments are not operations, so this is appropriately classified as valid.

crates/biome_rule_options/src/lib.rs (1)

342-342: LGTM!

Module export correctly placed in alphabetical order. The addition follows codebase conventions perfectly.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/valid/multi-named.graphql (1)

1-7: LGTM!

Test correctly validates that multiple named operations should not trigger the rule.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/invalid/with-subscription.graphql (1)

1-7: LGTM!

Test correctly validates that an anonymous operation alongside a named subscription should trigger diagnostics.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/valid/no-operations.graphql (1)

1-4: LGTM!

Test correctly validates that documents with no operations (fragments only) should not trigger the rule.

crates/biome_rule_options/src/use_lone_anonymous_operation.rs (1)

1-6: LGTM!

The options struct follows all required patterns and conventions for rule options, even though no options are currently needed.

crates/biome_graphql_analyze/tests/specs/nursery/useLoneAnonymousOperation/invalid/multi-anonymous.graphql (1)

1-7: LGTM!

Test correctly validates that multiple anonymous operations should trigger diagnostics.

crates/biome_graphql_analyze/src/lint/nursery/use_lone_anonymous_operation.rs (1)

55-101: LGTM!

The run() implementation correctly identifies anonymous operations by checking for both unnamed GraphqlOperationDefinition nodes and GraphqlSelectionSet nodes (which represent shorthand syntax). The early returns appropriately optimise for common cases.

We have repeated text range, which is a bit odd... it seems like a bug. Shouldn't we highlight the other anonymous operations?

The first range is actually on the full document.

I wanted to first mention that the document is invalid with "Document contains (multiple) anonymous operations." and then show the operations. But the initial report requires a textrange, so I set that to the full document. Maybe I can rewrite it to use the first query there and then loop over all the other operations.

7-16: Consider adding a valid example for clarity.

The changeset shows what's invalid but not what's valid. Adding a valid example (e.g., multiple named operations or a single anonymous operation) would help users quickly understand the rule's intent when reading the changelog.

Learning: In the Biome codebase, each lint rule has its own options type declaration (e.g., type Options = RuleNameOptions) as part of the codegen process, even if the options struct is empty or unused. This is standard practice and should not be flagged as an issue.

62-91: Consider simplifying by avoiding the intermediate cast.

The pattern of matching AnyGraphqlDefinition, casting to AnyGraphqlOperationDefinition, then matching again is a bit convoluted. You could extract the range and name check directly in the first match, avoiding the .syntax().clone().cast() dance entirely.

🔎 Proposed simplification
         for def in node.definitions() {
-            let operation = match def {
-                AnyGraphqlDefinition::GraphqlOperationDefinition(operation_definition) => {

-                }
-                AnyGraphqlDefinition::GraphqlSelectionSet(selection_set) => selection_set
-                    .syntax()
-                    .clone()
-                    .cast::<AnyGraphqlOperationDefinition>(),
+            let unnamed_range = match def {
+                AnyGraphqlDefinition::GraphqlOperationDefinition(op) => {
+                    operation_count += 1;
+                    op.name().is_none().then(|| op.range())

Learning: In the Biome codebase, each lint rule has its own options type declaration (e.g., `type Options = RuleNameOptions`) as part of the codegen process, even if the options struct is empty or unused. This is standard practice and should not be flagged as an issue.

Learning: When defining lint rules (declare_lint_rule!), only specify fix_kind if the rule implements an action(...) function. Rules that only emit diagnostics without a code fix should omit fix_kind. This applies to all Rust lint rule definitions under crates/.../src/lint (e.g., crates/biome_js_analyze/src/lint/...).

Learning: In Rust lint rules under the nursery category, the issue_number field in declare_lint_rule! is optional and should not be added unless there is a compelling reason. In code reviews, verify that no unnecessary issue_number is included in nursery lint declarations. Only add issue_number if there is an explicit, justified reason (e.g., tracked issue for external observers). This guidance broadly applies to all nursery lint rule files, not just the single file.

9-47: LGTM!

Rule declaration follows Biome conventions nicely: version: "next", proper use prefix, correctly sourced from ESLint GraphQL, and documentation format is spot on.


97-121: LGTM!

Diagnostic construction is solid — primary location from state.first()? with secondary details for additional anonymous operations, plus a helpful explanatory note.

53-53: Consider whether Options type is needed.

The UseLoneAnonymousOperationOptions type is declared but never accessed in the run function. If this is a placeholder for future configuration, consider adding a comment to clarify intent. Otherwise, you could use () as the Options type.

# Check if UseLoneAnonymousOperationOptions has any fields or configuration

Learning: In Rust lint rules under the nursery category, the issue_number field in declare_lint_rule! is optional and should not be added unless there is a compelling reason. In code reviews, verify that no unnecessary issue_number is included in nursery lint declarations. Only add issue_number if there is an explicit, justified reason (e.g., tracked issue for external observers). This guidance broadly applies to all nursery lint rule files, not just the single file.

9-47: LGTM! Well-structured rule declaration.

The rule declaration follows all guidelines: proper version: "next", correct use prefix (mandating anonymous operations only when alone), appropriate source attribution, and well-formatted documentation with correctly tagged examples.

97-121: Clear and helpful diagnostic.

The diagnostic accurately describes the issue and provides actionable guidance. The message works well whether there's one or multiple anonymous operations, and the detail/note structure effectively communicates the problem.

💡 Optional: Minor wording refinement

For slightly more concise phrasing, consider:

            markup! {
-                "Document contains an anonymous operation while defining more than one operation. This anonymous operation must be the only defined operation in this document or turned into a named operation."
+                "Document contains an anonymous operation while defining more than one operation. This anonymous operation must be the only defined operation in this document or given a name."
            },

"Given a name" is marginally more direct than "turned into a named operation", but the current wording is perfectly clear.

1-8: LGTM!

Imports are clean and appropriate for the rule implementation.


9-47: Excellent rule declaration.

Follows all conventions: proper documentation structure, correct metadata (version: "next", appropriate recommended: false for nursery), correct source attribution, and well-tagged examples. The rule name appropriately uses the use prefix per guidelines.

Based on learnings, the metadata is correctly configured.


55-95: Well-implemented logic.

The rule correctly identifies anonymous operations when multiple operations are present. The single for-loop approach efficiently processes definitions without redundant iterations, and the final condition (operation_count > 1 && !unnamed_operations.is_empty()) accurately captures the rule's intent.
