tsconfig Analyzer and Fix Suggestions
Analyze your tsconfig.json for strictness, module resolution, and alias safety, then apply practical fix suggestions with clear priority and rationale.
Paste your tsconfig.json content to detect strictness gaps, alias risks, and module configuration issues, then review prioritized and actionable fix suggestions.
Why Use This tsconfig Analyzer?
Compiler Option Validation
Checks strictness, module setup, path aliases, and project-level settings in one run.
Fix-Ready Suggestions
Provides concrete property-level suggestions with safe-auto-fix hints and rationale.
JSONC Aware Parsing
Supports tsconfig-style comments and trailing commas for real-world project files.
Private Browser Processing
Analysis runs locally in your browser, so tsconfig content never leaves your device.
Popular Use Cases
Harden Type Safety
Find missing strictness controls that let unsafe typing slip into production code.
Fix Alias Resolution
Catch baseUrl and paths mismatches that cause unresolved imports across environments.
Improve Build Reliability
Identify config combinations that create cross-platform or bundler-resolution drift.
Review PR Config Changes
Use analyzer output during code review to verify tsconfig changes are safe and intentional.
Migrate to Stricter TypeScript
Incrementally enable strict mode flags with confidence by seeing exactly which settings are missing and what each one controls.
Onboarding and Documentation
Generate a clear summary of an unfamiliar project's TypeScript configuration to accelerate onboarding and reduce setup questions.
About tsconfig Analyzer and Fix Suggestions
TypeScript Configuration Quality Evaluation
The tsconfig Analyzer and Fix Suggestions helps you evaluate TypeScript configuration quality using practical checks for strict mode coverage, module strategy, alias safety, and maintainability signals.
Diagnostics, Suggestions, and Loop-Scenario Detection
It accepts tsconfig JSONC input, returns prioritized diagnostics, and provides property-level suggestions. It also includes loop-scenario signal detection for success, failure, auto-fix, and retry-limit test inputs.
Module Strategy and Path Alias Validation
The analyzer checks module resolution strategy compatibility, validates that baseUrl and paths aliases are consistently configured, and flags combinations that commonly break bundler or runtime resolution.
Privacy and Browser-Only Processing
Your tsconfig content is analyzed entirely in the browser. No configuration data is sent to external servers, making this tool safe for internal codebases and proprietary project setups.

Frequently Asked Questions
Yes. It parses JSONC-style comments and trailing commas commonly used in tsconfig files.
No. It suggests safe and explicit fixes in-browser. You review and apply changes manually.
Yes. It highlights strictness gaps and provides focused recommendation paths for safer migration.
Yes. All processing runs locally in your browser without uploading configuration data.
It checks for modern module resolution settings like bundler and node16 and flags legacy node resolution when combined with ESM output, which can cause runtime import failures.
Yes. It validates that paths entries have corresponding baseUrl settings and flags aliases that could silently break at runtime if the bundler or runtime does not support them natively.
Yes. It is 100% free with no account or signup required.
