Lawnchair: Simple JSON Storage
JavaScript framework for making (mobile) web applications that interacts with a local, persistent storage.
Works with all modern browsers using WebKit (Chrome, Safari and MobileSafari). It also has adapters to Google Gear.
It uses JSON extensively. All data is stored and read as JSON. So, instead of using a classic remote server-side database like MySQL, MongoDB or CouchDB, you save everything as JSON — locally.
From their website:
“a lawnchair is sorta like a couch except smaller and outside. perfect for html5 mobile apps that need a lightweight, adaptive, simple and elegant persistence solution.”
