Wesa

Wesa is a CLI and library for performing storage schema migrations in browser extensions (Chrome/Firefox) packaged with webpack. The current stable version is 0.7.1, released sparsely. It helps manage storage revisions using a revision repository, similar to database migrations. Unlike generic migration tools, it targets browser.storage (local, session, sync) and integrates with webpack code splitting via dynamic imports. It requires Node.js >=24.0.0 and expects background scripts to call the migrate function with a context object.
