Support for PWAs via JS SDK
By that I mean as a Front End Browser Database.
Michel, I've moved on from MongoDB and have no idea what's happened with Realm.
I've just released a PWA which use YJS (CRDTs) to deliver full offline use and eventual consistency when back online. When online, all users update in real time along with full collaborative editing. You can check out clibu.com if you are interested.
Having full browser-side Realm support is a MUST.
Not only for PWAs with service worker and other features but also for SPAs, web pages.
In short, everything that runs in the browser and must have the same functionality as the mobile or desktop version.
