[CAP] Update standalone approuter
You can simply update your standalone approuter using cf push,
cd ~/projects/bookshop/app/approuter/
cf push bookshop-approuter # take your approuter name from the mta.yaml file
cd ~/projects/bookshop/
[nodejs] workspaces
If you have subdirectories or additional applications which have its own package.json file, you can add them via the workspaces setting to your main project.
{
"name": "my-project",
"workspaces": [
"./app/*"
]
}
When running npm install it will now also install the dependencies of all projects in the app folder.

[CAP] min and max functions
Since there is nothing in the official CAP documentation about min and max functions, I figured out the following syntax:
const result1 = await cds.run(`SELECT *, MAX(seqNr) FROM ${myTable} LIMIT 1`) //returns array
const result2 = await SELECT.one.from(myTable, [`MAX(seqNr)`]).columns('*') //returns object
const result3 = await SELECT.one.from(myTable).columns('MAX(seqNr)') //returns object containing only the max counter value
