Unpartial
Unpartial an interface.
It is very common to define a config interface and Partial<>
it in a function argument.
When we received the arguement, we want to merge it with our default config before using it:
import { unpartial } from 'unpartial'
interface Config {
require: { a: number }
optional?: { a: number }
}
const defaultConfig = { require: { a: 1 } }
function foo(givenConfig?: Partial<Config>) {
const config = unpartial(defaultConfig, givenConfig);
}
Code complete is avaiable as you type:
const config = unpartial(defaultConfig, { });
It also supports merging two default configs.
This is useful when you are extending interface from another package/class.
import { unpartial } from 'unpartial'
import { Option, defaultOption } from 'another-package'
interface MyOption extends Option { ... }
const myDefaultOption = { ... }
function foo(givenOption?: Partial<MyOption>) {
const option = unpartial(defaultOption, myDefaultOption, givenOption)
}
