Bump your dependencies and makes code changes for you if anything breaks.
About Docs
Bumpgen updates a specified dependency to a specified version and makes code changes when the upgrade breaks existing code. It parses the codebase into an AST with ts-morph to understand code relationships and external method type definitions, then creates a plan graph DAG to order fix steps.
Use requires an OpenAI API key, with gpt-4-turbo-preview as the only supported model at this time. It is installed globally with npm and run from the command line inside a repository.
