Setup Environment React Native by ONE Script

FlowChart

This script automates the installation and setup of the essential development environment on macOS, including:

Homebrew
RVM (Ruby Version Manager) and Ruby
NVM (Node Version Manager) and Node.js

What

If you’re using Zeego or any other React Native library that throws weird framework-related errors like “ReactCommon/RCTHost.h not found”, this is for you. The issue started with RN 0.78+ and usually only affects the old architecture with useFrameworks: 'static'.

Versions before 0.78, setups without useFrameworks, or users on the new architecture are not affected, thus do not need this workaround.

Fix for Expo users

I’ve prepared a config plugin for you. Create a file, e.g. plugins/with-runtime-framework-headers.js, with the following contents:

const { withPodfile } = require('expo/config-plugins')

Edit — February 2019

This gist had a far larger impact than I imagined it would, and apparently people are still finding it, so a quick update:

TC39 is currently moving forward with a slightly different version of TLA, referred to as 'variant B', in which a module with TLA doesn't block sibling execution. This vastly reduces the danger of parallelizable work happening in serial and thereby delaying startup, which was the concern that motivated me to write this gist
In the wild, we're seeing (async main(){...}()) as a substitute for TLA. This completely eliminates the blocking problem (yay!) but it's less powerful, and harder to statically analyse (boo). In other words the lack of TLA is causing real problems
Therefore, a version of TLA that solves the original issue is a valuable addition to the language, and I'm in full support of the current proposal, which you can read here.

I'll leave the rest of this document unedited, for archaeological

WSLg with OpenGL, Vulkan, and CUDA on (Official) Arch Linux and Ubuntu WSL Instances

Note: I haven't documented CUDA here. I'm lazy (and haven't tested on Arch). See https://documentation.ubuntu.com/wsl/en/latest/howto/gpu-cuda for that on Ubuntu.

Context

microsoft/wslg#1312:

So I got this working on both Ubuntu, and Arch. First, start with a fresh install (of archlinux from https://gitlab.archlinux.org/archlinux/archlinux-wsl or Ubuntu from wsl --install Ubuntu or https://apps.microsoft.com/detail/9pdxgncfsczv).

Arch

Docker + WSL2 + Containerlab

Hyper-V
