Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.

First off, bundle.
==================

1. cd to the project directory
2. Start the react-native packager if not started
3. Download the bundle to the asset folder:
curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"

Building a Maintainable, Agile Architecture for Realtime, Transactional Apps

A maintainable application architecture requires that the UI only contain the rendering logic and execute queries and mutations against the underlying data model on the server. A maintainable architecture must not contain any logic for composing "app state" on the client as that would necessarily embed business logic in the client. App state should be persisted to the database and the client projection of it should be composed in the mid tier, and refreshed as mutations occur on the server (and after network interruption) for a highly

CLJS in AWS Lambda Quick Start

Setup

First, a few dependencies:

1. Leiningen: https://leiningen.org/
2. Node.js & NPM: https://nodejs.org/
3. Serverless: https://serverless.com/
4. An active AWS account: https://aws.amazon.com/

Usage

Start up the new cljs.main with Node:

clj -Sdeps '{:deps {org.clojurescript {:git/url "https://github.com/clojure/clojurescript" :sha "3f4084efcb5cd92cceb8ca30765144691d8cfd7e"}}}' -m cljs.main -re node

The above works by specifying ClojureScript as a "git dep" and you can ensure that you are running the very latest by replacing the :sha value with the latest commit SHA at https://github.com/clojure/clojurescript.

Converting a Word Document to Markdown in One Move

The Problem

A lot of important government documents are created and saved in Microsoft Word (*.docx). But Microsoft Word is a proprietary format, and it's not really useful for presenting documents on the web. So, I wanted to find a way to convert a .docx file into markdown.

Installing Pandoc
