Express.js provides Codemod transforms to help you upgrade your express server when a feature is deprecated or removed.
Codemods are transformations that run on your codebase programmatically. This allows for a large amount of changes to be applied without having to manually go through every file.
With the codemod CLI you can run a workflow from the Codemod Registry. Replace <codemod> with the name of the codemod you want to run:
npx codemod @expressjs/<codemod>
For see the list of available codemods, visit the Express.js Codemod Registry.
You can also clone the repository and run the codemods locally. First, clone the repository:
git clone https://github.com/expressjs/codemod.git cd /path/to/your-project npx codemod workflow run -w /path/to/codemod/codemods/<recipe>/workflow.yaml
See the codemod CLI doc for a full list of available commands.
