127: PouchDB

Nolan Lawson a PM at Microsoft Edge joins us today to talk about PouchDB a popular open source project he’s a maintainer of. PouchDB is an open-source JavaScript database inspired by Apache CouchDB that is designed to run well within the browser. In this episode we get into what PouchDB is good at and what type of projects would benefit from using PouchDB for their persistence layer (turns out, many!). PouchDB is framework agnostic but plays very well with many popular frameworks and libraries. Nolan gets into the performance of PouchDB and also what storage mechanisms it supports which include IndexedDB, WebSQL, LevelDB and many more. The episode takes a very unexpected turn leaving Justin, Danny and Leon wrapping up with some of their own PouchDB experiences.
