Summary

Use useState:

1. if you manage JavaScript primitives as state
2. if you have simple state transitions
3. if you want to have business logic within your component
4. if you have different properties that don’t change in any correlated manner and can be managed by multiple useState hooks
5. if your state is co-located to your component
6. if you’ve got a small application (but the lines are blurry here)

Async Operations with useReducer Hook

9 March, 2019

We were discussing with @erusev what we can do with async operation when using useReducer() in our application. Our app is simple and we don't want to use a state management library. All our requirements are satisfied with using one root useReducer(). The problem we are facing and don't know how to solve is async operations.

In a discussion with Dan Abramov he recommends Solution 3 but points out that things are fresh with hooks and there could be better ways of handling the problem.

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

Lots of stack traces and error messages for CKAN, followed by a comment about how I fixed it (that time).
NB don't email me privately for help - ask on StackOverflow #ckan instead.

In this tutorial we're going to build a set of parser combinators.

What is a parser combinator?

We'll answer the above question in 2 steps.

1. What is a parser?
2. and, what is a parser combinator?

So first question: What is parser?
