packages/javascript/README.md (1)
14-24: Usage example is concise and demonstrates the key functionality.The example demonstrates the essential steps for using the package:
- Importing the JavaScript language module and NAPI functions
- Registering the dynamic language
- Parsing JavaScript code and accessing the root node
Consider adding another example demonstrating a more complex pattern matching use case to help users understand the full capabilities of the package.
packages/javascript/index.js (2)
6-7: LGTM! Consider adding TypeScript extensions if applicable.The extension list correctly includes common JavaScript file extensions. If this parser is intended to support TypeScript files as well, consider adding 'ts' and 'tsx' extensions to the list.
8-8: Consider adding a comment explaining the expandoChar's purpose.The
expandoCharproperty is set to '$', but its purpose isn't immediately clear to someone unfamiliar with the codebase. A brief comment explaining how this character is used in AST queries would improve maintainability.packages/javascript/package.json (2)
4-4: Add a package description.The description field is empty. Consider adding a brief description of what this package does, such as "JavaScript language support for ast-grep" to improve discoverability and provide context.
22-22: Add author information.The author field is empty. Consider adding the author's name, email, or organization to properly attribute the package.

packages/javascript/postinstall.js (1)
1-4: Looks good!The postinstall script correctly imports and calls the postinstall function from the
@ast-grep/setup-langpackage, passing the current directory. This is a common pattern for Node.js packages that need to perform setup steps after installation.packages/javascript/nursery.js (1)
1-16: Testing setup looks good and verifies the JavaScript parsing functionality.The nursery setup correctly configures the testing environment for JavaScript:
- It imports necessary dependencies
- Sets up the test environment with appropriate configuration
- Includes a test runner that verifies the parser can correctly identify a lexical declaration
This follows the pattern used by other language packages in the ast-grep ecosystem.
packages/javascript/index.d.ts (2)
1-7: Type definition looks good.The
LanguageRegistrationtype correctly defines the expected structure for language registration:
- Required properties:
libraryPathandextensions- Optional properties:
languageSymbol,metaVarChar, andexpandoCharThis type follows the standard pattern used by other language packages and provides clear typing information.
9-10: Default export is properly typed.The registration constant is correctly typed as
LanguageRegistrationand exported as the default export.packages/javascript/README.md (1)
1-12: Installation instructions are clear and complete.The README correctly specifies the necessary installation steps for a pnpm project:
- Installing the language package itself
- Installing the required
@ast-grep/napidependency- Optional installation of
@tree-sitter/clifor environments lacking prebuilt binariesThis provides users with the information they need to get started.
packages/javascript/package.json (2)
1-47: LGTM! Package structure follows npm conventions.The package.json is well-structured with appropriate scripts, dependencies, and configuration for integration into the ast-grep ecosystem. The build process using tree-sitter and the postinstall script for setup follow good practices for native modules.
23-23:✅ Verification successful
Verify if ISC license is intended.
The package specifies ISC license. Please verify if this matches the license used by other ast-grep packages or if it should be aligned with the project's overall licensing strategy.
🏁 Script executed:
#!/bin/bash # Check licenses of other ast-grep packages echo "Checking licenses of other ast-grep packages:" find . -name "package.json" | grep -v "node_modules" | xargs grep -l "\"license\":" | xargs grep "\"license\":"Length of output: 907
Licensing Consistency Confirmed
The verification shows that the vast majority of the ast-grep subpackages—including packages in Angular, C, C++, C#, Go, Python, SQL, and others—use the ISC license. The packages/javascript/package.json already aligns with this pattern by specifying ISC on line 23. (Note that the root package.json uses MIT, which appears to be an intentional difference in overall licensing strategy.)
Thus, no changes are required regarding the ISC license in packages/javascript.
