Is Database first concept in Node.js( Sequalize Orm or any other lib )

Question

hello every one,

 

I am looking for a solution, when I can use the existing database, using node js  ORM(seqalize or any other library) as db first concept like entity or linq. I mean I want to generate model using node.js orm based on existing  database. 

 

is there any way?  I googled and r&d for 2 days, but I couldn't get the solution.
