Static property descriptors

Last updated 15 days ago

Static property descriptors are standard JavaScript property descriptors. They are applied last thing when a stamp is being composed.

let MyStamp = stampit() // empty stamp creates empty objects
MyStamp.name === 'Stamp' // every stamp default name is "Stamp"
MyStamp = MyStamp.staticPropertyDescriptors({
name: { value: 'MyStamp' } // this meta data will be applied just after composition, i.e. immediately
})
MyStamp.name === 'MyStamp'

The code above adds some more metadata to the MyStamp stamp. It overwrites function name. (Property descriptors is the only way to change a function name.)

NOTE

The stampit and @stamp/it modules have the "name" feature built in.

const MyStamp = stampit({ name: 'MyStamp' })
MyStamp.name === 'MyStamp'

Other ways to add static property descriptors

Exactly the same stamp can be created in few ways. Here they all are.

const myStampName = {
name: { value: 'MyStamp }
}
const NamedStamp = stampit({
staticPropertyDescriptors: myStampName
})
const NamedStamp = stampit.staticPropertyDescriptors(myStampName)
const NamedStamp = stampit().staticPropertyDescriptors(myStampName)
