Developer builds namespaced-storage to fix browser storage chaos in large codebases

A frontend engineer at Snappfood created an open-source package called namespaced-storage to address architectural problems caused by multiple teams writing to the same global browser storage namespace. In large codebases, uncoordinated use of localStorage can cause silent key collisions, unclear data ownership, and accidental data loss when one team's clear() call wipes another team's data. The package lets each feature declare its own isolated store with a dedicated namespace prefix, preventing cross-team overwrites without relying on manual naming conventions. It includes TypeScript support for type-safe reads and writes, optional schema validation via tools like Zod, and a companion ESLint plugin and CLI to enforce boundaries at the tooling level. The project aims to make browser storage explicit, owned, and auditable across large engineering teams.
