Background

I decided to test my effects without using the Angular TestBed because this should be faster then using the entire TestBed when I only want to test the effect in isolation (https://ngrx.io/guide/effects/testing#setup-without-testbed). I am using Jest as test runner.

Repro-Steps

Consider this simplified, generic approach I used.

  it('should get data

The logged output does not match the example above.
For each i value, we should see something like i: 0 instead of just 0 for example.

Intended outcome

I'm building an application, and after doing some work with MobX, I ran a production build to ensure everything was working as expected, but it errored out. Development build does work exactly as intended, however.

Actual outcome

I get the following error:

✖ ERROR ./node_modules/mobx-react-lite/dist/observer.d.ts
ERROR in ./node_modules/mobx-react-lite/dist

The build section should talk about contrib. The contributing section should cover:

1. Differences between npm version and github version.
2. Process for building (or should that be in build) and running tests.
3. Contribution guidelines.

alibaba-fusion Select component (https://github.com/alibaba-fusion/next) used as below:

const dataSource = [
  { label: 'option1', value: 'option1' },
  { label: 'option2', value: 'option2' },
  { label: 'disabled', disabled: true }
]

<Select dataSource={dataSource} />

<Select>
     <Option value="small">Small</Option>
     <Option value="medium">Medium</Option>
     <Option val

You've kindly provided many helpful examples, however they are all running in JSbin-esque services.

Aside from the high level concepts and APIs, I'd like to see an example application or skeleton app that includes modern tooling: tree shaking/dead code elimination via Rollup, etc.

The partial.lenses readme discusse

Gaps:

• hot and cold - Difference between the two, how to assign values, valid string syntax
• getTestScheduler - Why you might need this when testing streams that require custom schedulers
