Even Object Brace Linting

Build a lint helper that enforces symmetrical spacing inside curly braces for single-line object literals, patterns, and import/export named clauses. The linter should use the dependency below to apply this spacing rule.

Capabilities

Symmetric spacing on single-line objects

• Single-line object literals or patterns must use matching spacing (either no spaces or one space) after { and before }; mismatched spacing produces a lint error. @test
• Objects using trailing commas still respect the symmetric spacing requirement. @test

Destructuring compliance

• Object destructuring bindings respect the same symmetric spacing; inconsistent spacing in bindings is reported as an error. @test

Import/export specifier compliance

• Import/export named specifiers follow the same symmetric spacing rule; misaligned spacing is reported. @test

Nested content exceptions

• Nested objects or arrays inside object literals do not require extra padding beyond the outer brace spacing expectation. @test

API

export type LintMessage = {
  ruleId: string;
  message: string;
  line: number;
  column: number;
};

export type LintResult = {
  filePath: string;
  errorCount: number;
  messages: LintMessage[];
};

export async function lintObjectSpacing(
  codeSamples: Array<{ filePath: string; contents: string }>
): Promise<LintResult[]>;
