The Composable Architecture

The Composable Architecture(TCA)는 일관되고 이해할 수 있는 방식으로 어플리케이션을 만들기 위해 탄생한 라이브러리입니다. 합성(Composition), 테스팅(Testing) 그리고 인체 공학(Ergonomics)을 염두에 둔 TCA는 SwiftUI, UIKit을 지원하며 모든 애플 플랫폼(iOS, macOS, tvOS, watchOS)에서 사용 가능합니다.

GitHub GraphQL API v4 Examples

Here are two queries that look up information about a pull request via GitHub's GraphQL API v4. The first looks up a pull request by number, the second looks up a pull request by ref (i.e. commit hash, branch name, tag name).

Why tho

While it is trivial to use the RESTful v3 API to look up a pull request by number, the GraphQL API is the only way to do the same thing for an arbitrary reference in a single HTTP request.

These took a bit of trial and error in the GitHub's GraphQL Explorer and various support threads to get right, so I'm putting them up here for posterity.
