CAP - CDS Repl

[#1]

Dear CAP Community,

I am trying to experiment with the cds repl using the famous bookshop demo example rolled out by SAP.

I have set up the Visual Studio code and installed all the necessary node modules like @sap/cds-dk along with installation of npm and nodejs. After launcing the cds repl using cds r and instantiating the cds facade object using -> const cds = require('@sap/cds').connect('db') in the repl, I am trying to call cds.entities, but I don't get the list of entities defined - Books, Authors, Orders. It is coming blank, do we know why?

Best Regards,

Tanmoy

You have to bootstrap your bookshop within your repl session:

❯ cds r
Welcome to cds repl v 7.5.0
> var server = cds.test() // ⬅️ Bootstrap works like this if you started repls within the booskhop dir
> [cds] - loaded model from 5 file(s):

  srv/user-service.cds
  srv/cat-service.cds
  srv/admin-service.cds
  db/schema.cds
  ../../../cds/common.cds

[cds] - connect to db > sqlite { url: ':memory:' }
  > init from db/init.js


…


> { Genres } = cds.entities()
(ns) => !ns ? children : this.childrenOf (ns,filter)
> Genres.elements
