Support for nodejs "fermium" LTS v14 in order to use newer packages/libraries/dependencies

We love your typescript-express-sequelize bootstrap, @maximegris!

However, we are unable to integrate a service that provides npm packages that require node 13.5 or newer.
As of this writing, the latest lts is "fermium" v.14.17 - the previous lts "erbium" v12.22 won't suffice - we would greatly appreciate updates, or help/advice.
