My current TypeScript type definition is as follows:
type MyKeys = 'foo' | 'bar' | 'baz'
I am looking to create a custom type that includes keys from MyKeys, but also additional keys, like so:
type CustomType = {
[key in MyKeys]: boolean
quux: boolean // <--- Error: '}' expected.ts(1005)
}
How can I combine generic keys with specific key names in this scenario?
If you're looking to create a type with both specified keys and additional properties, you can utilize an Intersection Type:
type FooType = {[key in MyKeys]: boolean} & {
quux: boolean
}
Alternatively, as suggested by @jcalz, another approach is to use the Record<> type:
Record<MyKeys | 'quux', boolean>
This will result in creating an object that combines the specified keys along with the 'quux' property:
