We are starting a new application which will only be used for building REST APIs. We have used loopback 3.0 in the past but now when loopback 4.0 is available I was wondering what is the best option: 3.0 or 4.0.
Is loopback 4.0 stable enough for a complex production app, as there was a number of issues we faced with loopback 3.0 when it was new?
LoopBack 4.0 (GA) is the next generation of the LoopBack framework, with a completely rewritten core foundation and significantly improved programming model (when compared against the previous version).
To facilitate migration between LoopBack 3 and LoopBack 4, you can mount your LoopBack 3 application on top of a LoopBack 4 project and can envision for potential issues which may arise in future. See Migrating-from-LoopBack-3 for more info.
Hope this helps!
