clone-class's Issues

Can not infer the private constructor return type.

I want to know what is the InstanceType of a class with private constructor:

class PrivateConstructorClass {
  private constructor () {}
}

function test<T> (klass: T) {
  // T here is `typeof PrivateConstructorClass`
}

test(PrivateConstructorClass)

How can I get the type PrivateConstructorClass instead of typeof PrivateConstructorClass in method test()?

Related unit tests

clone-class/src/constructor.spec.ts

Lines 26 to 38 in 19a27f0

test('constructor()', async t => {
class PrivateConstructorClass {
private constructor () {}
}
const C = constructor(PrivateConstructorClass)
const typeTest: AssertEqual<typeof C, PrivateConstructorClass> = true
t.ok(typeTest, 'should be same after constructor')
})

If we can fix the above unit test, then we are solved this problem.

Behavior not expected when the class static property initialized in defination.

In the past two days, I'm experiencing a wired "bug" when using cloneClass:

class Test {
  static meaning = { life: 42 }
}

const T1 = cloneClass(Test)
const T2 = cloneClass(Test)

T1.meaning.life = 17
console.log(T2.meaning.life)
// output 17!!! but we are expecting 42 at here.

After digging into the implementation of the cloneClass, I found that when a static property of the class is cloning, we will copy the value of the static property value to the cloned class.

Which means that the Object value will be shared between all the cloned classes.

So finally we have to check this situation and throw an Error in the cloneClass to forbidden initializing the static property in the class.

Version 10 of node.js has been released

Version 10 of Node.js (code name Dubnium) has been released! 🎊

To see what happens to your code in Node.js 10, Greenkeeper has created a branch with the following changes:

  • Added the new Node.js version to your .travis.yml

If you’re interested in upgrading this repo to Node.js 10, you can open a PR with these changes. Please note that this issue is just intended as a friendly reminder and the PR as a possible starting point for getting your code running on Node.js 10.

More information on this issue

Greenkeeper has checked the engines key in any package.json file, the .nvmrc file, and the .travis.yml file, if present.

  • engines was only updated if it defined a single version, not a range.
  • .nvmrc was updated to Node.js 10
  • .travis.yml was only changed if there was a root-level node_js that didn’t already include Node.js 10, such as node or lts/*. In this case, the new version was appended to the list. We didn’t touch job or matrix configurations because these tend to be quite specific and complex, and it’s difficult to infer what the intentions were.

For many simpler .travis.yml configurations, this PR should suffice as-is, but depending on what you’re doing it may require additional work or may not be applicable at all. We’re also aware that you may have good reasons to not update to Node.js 10, which is why this was sent as an issue and not a pull request. Feel free to delete it without comment, I’m a humble robot and won’t feel rejected 🤖
