Abstract

AssemblyScript Migration Guide

Up until now, subgraphs have been using one of the first versions of AssemblyScript (v0.6). Finally we've added support for the newest one available (v0.19.10)! 🎉

That will enable subgraph developers to use newer features of the AS language and standard library.

This guide is applicable for anyone using graph-cli/graph-ts below version 0.22.0. If you're already at a higher than (or equal) version to that, you've already been using version 0.19.10 of AssemblyScript 🙂

Note: As of 0.24.0, graph-node can support both versions, depending on the apiVersion specified in the subgraph manifest.

Introduction to React

React is the V in MVP (Model-View-Controller)
It's architecture is similar to the Web Components standard
Simple said: You can create your "own html tags" like
React then reassembles your components into the DOM and manages the expensive DOM updates (throught diffing a shadow DOM)

Raise Open File Limits in OS X

in OS X 10.4 to macOS sierra 10.12 and maybe higher!

Create Launcher Script:

`/Library/LaunchDaemons/limit.maxfiles.plist`

Copy this entire code block and paste it into your terminal and push Return to create this file for you with correct permissions. It will (probably) ask for your password:

$ npm install --save babel-cli babel-preset-es2015
$ npm install --save-dev jasmine

.babelrc:

{
 "presets": ["es2015"]

Stylus Best Practices

Introduction

This is a curated set of conventions and best practices for Stylus, an expressive, dynamic, robust and advanced CSS preprocessor. Frustrated with there not being a set of conventions set in place (that could be easily found), I set forth to find out on my own.
