What is SWC Config Validator?
The SWC Config Validator is a specialized utility designed to ensure your SWC transpilation layer is robust and error-free. By analyzing .swcrc files or SWC configurations nested within package.json, this tool identifies over 22 unique issues ranging from critical JSON syntax errors to subtle transform conflicts and deprecated settings. It is an essential addition to any modern JavaScript or TypeScript toolchain using Openclaw Skills for automated code quality assurance.
Beyond basic syntax checking, it audits specific logic paths such as JSX parser requirements, module type compatibility (ESM vs. CommonJS), and minification strategies. Whether you are debugging a Next.js build or optimizing a custom Turbopack setup, this skill provides the technical clarity needed to maintain high-performance build pipelines.
SWC Config Validator Use Cases
- Validating .swcrc configurations during CI/CD pipeline stages to prevent build failures.
- Auditing Next.js or Turbopack projects for transform conflicts and deprecated keys.
- Explaining complex SWC configurations in human-readable terms for team reviews.
- Debugging transpilation issues related to TypeScript decorators or React JSX transforms.
- Enforcing minification best practices and environment-specific build settings.
How SWC Config Validator Works
- The tool locates the configuration source, supporting both standalone .swcrc files and the swc key within package.json.
- It performs a structural pass to validate JSON integrity and check for required top-level keys like jsc.
- A deep-logic audit is executed against 22+ rules covering parser syntax, module types, and experimental transforms.
- Findings are categorized by severity (Error, Warning, Info) and mapped to specific line-item rules.
- The skill outputs the results in your preferred format (Text, JSON, or Summary) and returns a CI-compatible exit code.
SWC Config Validator Setup
The SWC Config Validator is a lightweight Python-based tool requiring no external dependencies. Ensure you have Python 3.8+ installed.
# Clone or download the script to your project
# Run a validation check on your existing config
python3 scripts/swc_config_validator.py validate .swcrc
# For machine-readable results in automation workflows
python3 scripts/swc_config_validator.py validate .swcrc --format json
SWC Config Validator Data Schema & Taxonomy
The skill organizes validation results based on a structured rule taxonomy. When utilizing this within Openclaw Skills, you can expect data categorized as follows:
| Category | Description |
|---|---|
| Structure (S) | Validates file accessibility, JSON syntax, and top-level key schema. |
| JSC Config (J) | Audits parser settings (ECMAScript/TypeScript) and compilation targets. |
| Modules (M) | Ensures compatibility between module types (UMD, AMD, CJS) and parser features. |
| Transform (T) | Checks for React, Decorator, and Class Field transform conflicts. |
| Minification (N) | Validates minification flags and compression settings. |
| Best Practices (B) | Suggests improvements for sourceMaps and environment-specific configs. |
SWC Config Validator Advanced Features
- Strict Mode: Force the validator to treat all warnings as errors to ensure maximum build consistency.
- Multi-Format Output: Choose between human-readable text with severity icons or machine-parseable JSON arrays.
- Configuration Explanation: Use the explain command to transform a dense JSON config into a clear, human-readable breakdown of the build logic.
- Automated Suggestions: Generate actionable improvement hints to align your config with modern SWC standards.
- Zero-Dependency Architecture: Runs natively using only the Python standard library for easy integration into any environment using Openclaw Skills.
