justmoon / constitute Goto Github PK

I apologize for my stupid question beforehand.

I was trying to mock constitute, using
jest.mock( 'constitute' )

but it seems to throw me an error
TypeError: _dec is not a function

Is there a way where I can mock constitute function, properly?

Hello,

I think it would be great to support libraries on the container that don't need to be instantiated and can be referenced by using the library itself. Currently I have to do this:

libraries.js:

import $ from 'jquery';
import { Value } from 'constitute';

export const jQuery = new Value($);

Then, I have to find wherever the libraries.js file is located relative to my current script and pass in the correct value.

test.js:

import constitute, { Dependencies, Value } from 'constitute';
import {jQuery} from '../some/path/to/lib/libraries.js';

@Dependencies(jQuery)
class Test {
   constructor($) {
    this.$ = $;
   }
}

While this isn't the worst thing in the world, I think it would be nice to be able to reference jQuery as a dependency and the system knows to treat it as a Value (aka library in my case).

config.js:

import _ from 'lodash';
import $ from 'jquery';
import constitute from 'constitute';

// configuration
constitute.addValues([_, $, ...etc]);

example.js:

import _ from 'lodash';
import $ from 'jquery';
import constitute, { Dependencies } from 'constitute';

@Dependencies(_, jQuery)
class Test {
   constructor(_, $) {
    this._ = _;
    this.$ = $;
   }
}

I think this way we could continue to import libraries as we normally do while letting constitute replace it where necessary if we overwrite it. I'm not sure how this works under the hood to know if it's even possible but I think it would make things a little more maintainable. Or is there perhaps a better way mockup when I did in the first scenario?

Thanks!

I want to use something like constitute(Person, user_id) for new Person(depA, depB, user_id), is it possible?

Consider the following code example:

class Foo {

  bar = 'should be overwritten';

}

let foo1 = constitute(Foo);
let foo2 = constitute(Foo);

foo1.bar = 'i have the new value!';

console.log('foo 1:');
console.log(foo1.bar);

console.log('foo 2:');
console.log(foo2.bar);

In this case, constitute should have cached the instance of Foo when setting foo1. Then foo2 should therefor use the same instance as foo1;

However this is the console output I received:

foo 1:
> i have the new value!
foo 2:
> should be overwritten
