Summary of Changes

Hello @UziTech, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents a significant refactoring effort to transition the project to TypeScript. This change aims to improve code reliability, enhance developer tooling, and facilitate easier maintenance and future development by leveraging static type analysis. All JavaScript source and test files have been converted, and the build and test infrastructure has been adapted accordingly.

Highlights

• TypeScript Conversion: The entire project has been migrated from JavaScript to TypeScript, introducing static type checking across the codebase.
• Type Definitions: New type definition files (src/declarations.d.ts and src/types.ts) have been added to provide strong typing for external modules and internal data structures like Spec, TestSection, and Tests.
• Build and Test Workflow Updates: The package.json scripts have been updated to include a build command (tsc) and the test command now uses tsx to run TypeScript test files directly, ensuring type-checked tests.
• Dependency Updates: Numerous development dependencies have been added or updated in package-lock.json and package.json to support the TypeScript ecosystem, including typescript, @types/node, tsx, esbuild, and check-dts.
• Project Configuration: A tsconfig.json file has been added to configure the TypeScript compiler settings, defining target, module resolution, output directory, and strictness rules.

Code Review

This pull request primarily focuses on migrating the project to TypeScript, introducing type definitions for existing modules and functions, and updating the build and test processes accordingly. Key changes include adding tsconfig.json, introducing a types.ts file for core data structures, and updating package.json to reflect the TypeScript build (tsc) and test execution (tsx). Dependencies like @types/node, check-dts, tsx, and typescript were added, and js-yaml was updated. The .gitignore file was updated to include the new lib output directory. Review comments suggest refining type definitions in src/declarations.d.ts for front-matter and @markedjs/html-differ to be more specific than any, and correcting the return type of parseMarked in src/run-tests.ts to string | Promise<string> to accurately reflect marked.parse()'s behavior.

Code Review

This pull request is an excellent migration from JavaScript to TypeScript. The conversion is thorough, introducing strong typing across the codebase, which significantly improves maintainability and developer experience. Key improvements include the addition of a well-configured tsconfig.json with strict mode, centralized type definitions, and the correction of several async/await related bugs. The changes are clean and adhere to TypeScript best practices. I have only a couple of minor suggestions to further improve type safety in the test files.

Code Review

This pull request primarily focuses on migrating the project to TypeScript, introducing type definitions, and updating the build and test infrastructure accordingly. Key changes include adding a tsconfig.json file, updating package.json to define main, types, and exports fields pointing to a new lib directory for compiled output, and introducing new build and test:types scripts. Many new development dependencies were added to package-lock.json, including typescript, tsx, and @arethetypeswrong/cli, along with various other packages to support the new tooling and type checking. Code files (src/get-tests.ts, src/helpers.ts, src/html-differ.ts, src/load-tests.ts, src/output-table.ts, src/run-tests.ts) were refactored to include TypeScript type annotations, and a new src/types.ts file was added to define core interfaces. Additionally, src/declarations.d.ts was introduced for external module type declarations. Some functions like firstDiff in src/html-differ.ts were made synchronous, and corresponding await calls were removed from test files.
