LoopBack – 2020 Goals and Focus (strongloop.com)

I definitely don't like LoopBack in many ways :

- custom relationship (hasMany - hasOne - belongsTo - etc.)

- lack of documentation

- readability

- overriding and custom model methods

- console output in bottom banner

- too heavy compared to Java Spring framework (this is just one example)

- realy hard to custom in general

- and more...
