What is semantic matching in the context of this skill?

Semantic matching allows patterns to match code based on type information rather than just syntax. This means a single pattern can match various import styles or call signatures that resolve to the same underlying type.

Does this skill help with testing custom recipes?

Yes, it includes specific templates and guides for testing strategies using RecipeSpec and rewriteRun to ensure your transformations work as intended.

What is the primary benefit of the rewrite() helper?

The rewrite() helper is the recommended approach for simple substitutions. It provides a clean, declarative way to define 'before' patterns and 'after' templates, automatically handling code formatting.

Can I use this skill to write OpenRewrite recipes for Java?

No, this skill is specifically optimized for TypeScript-based recipe authoring. For Java recipes, you should use the 'writing-openrewrite-recipes' skill.

開発者ツール

Builds automated code transformation and refactoring tools using OpenRewrite's TypeScript API and visitor patterns.

概要

This skill empowers developers to create sophisticated, automated code transformation recipes for JavaScript and TypeScript projects using the OpenRewrite framework. It provides a comprehensive guide for implementing visitor patterns, leveraging Lossless Semantic Tree (LST) concepts, and using declarative pattern-to-template matching for large-scale refactoring and migrations. By streamlining the development of custom recipes, it enables teams to automate repetitive code maintenance tasks, enforce best practices, and perform complex architectural migrations with precision and safety.
