What is the interface type format in the angular cli?

Question

I was looking at the docs and became lost.

ng generate interface <name> <type>

However it doesn't tell what to put in for type. Like is it just a string, object, array, etc or can I specify properties like email:String username:String age:Number?

Answer 1

Using Angular CLI,

ng g i filename

will create a file by the name filename.ts and will have export interface filename {} in it

Answer 2

ng generate will generate

filename <name>.<type>.ts content:

export interface <name> { //camel case

}

ie

ng generate interface Itest sometype generates file name itest.sometype.ts content

export interface Itest {
}
