Introduction To Flow

Intended for developers interested in getting started with Flow. At the end of this introduction, you should have a solid understanding of Flow and how to apply it when building an application.

Part 1: Flow Fundamentals For JavaScript Developers

Covers all the basics needed to get started with Flow.

Part 2: Flow Fundamentals For ReactJS Developers

Covers all the basic needed to get started with Flow and ReactJS.

Chapter 1: Using Flow

Introduction

Why does it make sense to use FlowType or TypeScript when working with JavaScript? A good approach in answering this question is to build a small game or application to make the benefits clear.

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
Create or import a key -- see below for https://keybase.io
Run gpg --list-secret-keys and look for sec, use the key ID for the next step
Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

These links no longer work. Springer have pulled the free plug.

Pull Request Etiquette

Why do we use a Pull Request workflow?

PRs are a great way of sharing information, and can help us be aware of the changes that are occuring in our codebase. They are also an excellent way of getting peer review on the work that we do, without the cost of working in direct pairs.

Ultimately though, the primary reason we use PRs is to encourage quality in the commits that are made to our code repositories

Done well, the commits (and their attached messages) contained within tell a story to people examining the code at a later date. If we are not careful to ensure the quality of these commits, we silently lose this ability.
