PouchDB – The Database that Syncs!
PouchDB was created to help web developers build applications that work as well offline as they do online.
If you think you've found a bug in PouchDB, please write a reproducible test case and file a Github issue. We recommend bl.ocks.org for code snippets, because some iframe-based services like JSFiddle and JSBin do not support IndexedDB in all browsers. You can start with this template.
If you like to live on the bleeding edge, you can find the PouchDB nightly builds at pouchtest.com/nightly.
For a concise list of breaking changes, there's the wiki list of breaking changes.
Keep in mind that PouchDB is auto-migrating, so a database created in 1.0.0 will still work if you open it in 4.0.0+. Any release containing a migration is clearly marked in the release notes.
We're always looking for new contributors! If you'd like to try your hand at writing code, writing documentation, designing the website, writing a blog post, or answering questions on StackOverflow, then we'd love to have your input.
If you have a pull request that you'd like to submit, please read the contributing guide for info on style, commit message format, and other (slightly!) nitpicky things like that. PouchDB is heavily tested, so you'll also want to check out the testing guide.
