I worked for a bit on a code gen based typescript postgres builder, but haven't had time lately to build it out - https://github.com/Sammons/morbid

I really think typescript would benefit from a good solution to this.

I do like the code-gen solution a lot. You can create code that is far less bloated than a generic framework.

I am old fashioned. I like to start with the database schema and generate code from that. I make a change in the schema I regen the code. Thanks for partial classes in C# I can persist customizations between code-gens if necessary.
