First, give yourself a hearty pat for making it through. Writing a codemod is an advanced technique, and you likely encountered and had to quickly understand several new concepts.
To summarize what you learned:
@codemod-utilsprovides a set of tools and conventions to help you write codemods.- Break the problem into small steps. There may be a sequence of steps that makes it easier to solve the problem.
- Before implementing the first step, create fixture project(s) for acceptance tests. You can then run
./update-test-fixtures.shto see the effect of your code change. - Take the simplest approach to implement steps quickly. Prefer duplication over premature abstraction.
- After implementing all steps, refactor code. Write integration and unit tests to improve documentation.
