I am currently working on creating a function that requires one property as an argument, but could potentially have additional properties as well. Here is an example:
interface Foo {
bar: string;
}
function someFunc(obj) {
// implement functionality here
}
someFunc({bar: 'test', biff: 'test2'})
The obj parameter passed into the someFunc function may contain any number of properties, but it must always include the bar property.
Note: If your argument is not an object literal, it will work as intended.
interface Foo {
bar: string;
}
function someFunc(obj: Foo) {
// perform some action
}
const foo = {
bar: 'test',
biff: 'test2'
}
someFunc(foo)
If you prefer to explicitly allow object literals to have excess properties, you can include an index signature.
interface Foo {
bar: string;
[index: string]: unknown;
}
function someFunc(obj: Foo) {
// perform some action
}
someFunc({
bar: 'test',
biff: 'test2'
})
To ensure your obj parameter is typed, you can define it as {[key: string]: any}
This indicates that the input should be an object with one or more properties, and the type of each property can be any
function someFunc(obj: {[key: string]: any}) {
// perform some actions
}
