@vates/decorate-with
Creates a decorator from a function wrapper
Install
Installation of the npm package:
npm install --save @vates/decorate-with
Usage
decorateWith(fn, ...args)
Creates a new (legacy) method decorator from a function decorator, for instance, allows using Lodash's functions as decorators:
import { decorateWith } from '@vates/decorate-with'
class Foo {
@decorateWith(lodash.debounce, 150)
bar() {
// body
}
}
decorateClass(class, map)
Decorates a number of accessors and methods directly, without using the decorator syntax:
import { decorateClass } from '@vates/decorate-with'
class Foo {
get bar() {
// body
}
set bar(value) {
// body
}
baz() {
// body
}
}
decorateClass(Foo, {
// getter and/or setter
bar: {
// without arguments
get: lodash.memoize,
// with arguments
set: [lodash.debounce, 150],
},
// method (with or without arguments)
baz: lodash.curry,
})
The decorated class is returned, so you can export it directly.
To apply multiple transforms to an accessor/method, you can either call decorateClass multiple times or use @vates/compose:
decorateClass(Foo, {
baz: compose([
[lodash.debounce, 150]
lodash.curry,
])
})
perInstance(fn, ...args)
Helper to decorate the method by instance instead of for the whole class.
This is often necessary for caching or deduplicating calls.
import { perInstance } from '@vates/decorateWith'
class Foo {
@decorateWith(perInstance, lodash.memoize)
bar() {
// body
}
}
Because it's a normal function, it can also be used with decorateClass, with compose or even by itself.
decorateMethodsWith(class, map)
Deprecated alias for
decorateClass(class, map).
