You should look into Feathers JS [0]. You've the option to write in Javascript or Typescript and its built on top of nodejs/express.
Feathers JS has got builtin authentication and it is easy to add tenants. I've created a quick example and published it here [1], there maybe some rough edges, please mail me if you have any questions.
As others have mentioned with multi tenancy you must have good test cases that verify you've appropriate filters in place to avoid leaking data.
