How to install this addon?

[denzo]

I used ember install ember-microstates but then get an error:

ember.debug.js:52291 Uncaught Error: Compile Error: let is not a helper

[taras]

If you copy and pasted an example from the README, then you probably got {{let}} in your code.

You can install ember-let with ember install ember-let (make sure to restart your server bofore trying again)

[ming-codes]

@taras It seems like ember-let should be a dependency then.

[taras]

@ming-codes It's not strictly a dependency because you don't need let but it's a convenient way to use it.

@denzo did my suggestion resolve your issue?

[vasilakisfil]

@taras there should be at least a reference in the readme

[cowboyd]

Yeah, we should probably include a link to ember-let

How do you use it without let? What is the equivalent of using the type helpers like Boolean from within a controller or component instead of using let in the template?

[cowboyd]

I think that @knownasilya might have the best answer for this.

[taras]

There is a Pull Request in the works #69 that's a good place to look

[knownasilya]

Looks like @taras beat me to it 👍

#72 introduced state computed property macro. It can be used as you described.

import Component from '@ember/component';
import { state } from '@microstates/ember';

export default Component.extend({
  isOpen: state(false)
})

A new release of @microstates/ember is coming imminently.
