What is Bundle Checker?
Bundle Checker is a zero-configuration diagnostic tool designed to eliminate the mystery behind bloated web applications. By integrating this capability into the Openclaw Skills library, developers can automatically scan their projects to pinpoint heavy dependencies and identify exactly what is consuming space. It provides actionable intelligence to help you trim your build size and improve site loading speeds, ensuring your application remains lean and efficient.
This tool bridges the gap between raw data and actionable refactoring. Instead of just seeing a large file size, you get specific advice on tree-shaking opportunities and lighter library alternatives. It is an essential addition to any developer's toolkit for maintaining high-performance web standards without manual auditing overhead.
Bundle Checker Use Cases
- Analyzing current project build output for size regressions.
- Evaluating the impact of new dependencies before merging them into production.
- Identifying tree-shaking opportunities during performance audits.
- Troubleshooting slow-loading applications by pinpointing large dependency trees.
How Bundle Checker Works
- The tool scans your local package.json and project build output directory to map dependency usage.
- it identifies the largest dependencies and analyzes the overall bundle composition.
- The analysis data is sent to GPT-4o-mini to recognize common bloat patterns and optimization paths.
- The AI generates a report with specific suggestions, such as switching to lighter libraries or adjusting build configurations.
- Developers receive a prioritized list of actions to reduce the final bundle size.
Bundle Checker Setup
Ensure you have Node.js 18 or higher installed on your system. This tool requires an OpenAI API key to provide AI-powered insights.
# Run the checker directly via npx
npx ai-bundle-check
# Configure your environment variable
export OPENAI_API_KEY='your_api_key_here'
Bundle Checker Data Schema & Taxonomy
The skill organizes its analysis based on the structure of your project and the build artifacts generated. Below is a breakdown of the data points analyzed:
| Data Point | Description |
|---|---|
| Dependencies | Scans package.json to identify top-level and nested libraries. |
| Build Assets | Analyzes the physical size of JS/CSS files in the output folder. |
| AI Recommendations | Semantic suggestions for library replacements (e.g., Moment.js vs. date-fns). |
| Optimization Flags | Identifies if tree-shaking or code-splitting is underutilized. |
Bundle Checker Advanced Features
- Support for verbose reporting to get a granular breakdown of every module.
- Target directory specification for analyzing specific micro-frontends or sub-packages.
- Automated CI/CD integration to monitor bundle size trends over time.
- Intelligent alternative recommendations based on the Openclaw Skills knowledge base.
