Imagine having an object literal like this:
const defaultConfig = {
size: 'medium',
shape: 'circle',
material: 'metal'
}
Is there a simple method to generate an interface for this object, instead of manually creating one like this?
interface Configuration {
size: string,
shape: string,
material: string
}
In the most recent updates of TypeScript, there is a new capability to extend type aliases using an interface. This can be achieved by creating an interface as demonstrated below:
const defaultOptions = {
size: 10,
color: 'blue',
shape: 'circle'
};
type OptionsTypeAlias = typeof defaultOptions;
interface Options extends OptionsTypeAlias {
}
However, some developers may argue that this additional step is unnecessary and instead prefer a more concise approach:
type Options = typeof defaultOptions;
