What is Bundle Checker?
Bundle Checker is a developer-centric utility designed to eliminate the guesswork involved in optimizing modern web applications. By scanning your project's build artifacts and dependency manifests, it pinpoint exactly which libraries are contributing to slow load times. As a featured entry in the ecosystem of Openclaw Skills, it provides more than just raw data; it uses artificial intelligence to recommend specific code-splitting strategies and lighter package alternatives.
This tool is part of the LXGIC Dev Toolkit, aimed at helping developers maintain high-performance applications without complex manual audits. It bridges the gap between identifying a large bundle and knowing the precise steps required to shrink it, such as switching from Moment.js to Date-fns or implementing dynamic imports.
Bundle Checker Use Cases
- Debugging performance regressions when application load times increase unexpectedly.
- Evaluating the footprint of a new library before committing it to the production codebase.
- Automating bundle size audits during CI/CD failure scenarios.
- Identifying tree-shaking opportunities in legacy projects with heavy dependency chains.
How Bundle Checker Works
- The skill scans the local environment for package.json and the compiled build output directory.
- It maps the composition of the bundle to identify the largest dependencies and modules.
- The analysis data is sent to GPT-4o-mini, which compares the findings against a database of common bloat patterns.
- The tool generates a report containing specific recommendations for lighter libraries and tree-shaking configurations.
- Developers receive a prioritized list of actions to reduce the total JavaScript payload.
Bundle Checker Setup
The Bundle Checker requires Node.js 18 or higher and a valid OpenAI API key. No permanent installation is necessary as it can be run directly via npx.
# Set your API key
export OPENAI_API_KEY='your_api_key_here'
# Run the analysis in your project root
npx ai-bundle-check
Bundle Checker Data Schema & Taxonomy
The skill organizes its findings based on the relationship between package manifests and final build chunks. The output includes:
| Component | Description |
|---|---|
| Dependency Audit | A breakdown of the largest node_modules identified in the build. |
| Bloat Score | A metric indicating the potential for size reduction. |
| AI Optimization Plan | Step-by-step instructions for refactoring or library replacement. |
| Config Hooks | Recommended changes to Webpack, Vite, or Rollup configurations. |
Bundle Checker Advanced Features
- Support for specific directory targeting to analyze sub-projects or monorepo packages.
- Verbose reporting mode for a detailed breakdown of the internal dependency tree.
- Automated recommendation engine for dynamic imports to facilitate better code splitting.
- CI-compatible output for integration into automated performance monitoring workflows using Openclaw Skills.
