require 'fileutils'

# __FILE__ keyword in ruby
puts "The current ruby file being executed is #{__FILE__}"

# Gets the directory name of the file being executed
current_directory = File.dirname(__FILE__)
puts "The current directory is #{current_directory}"

# expands to reveal the pwd (Present working directory)

Caveats

Remember that using vue jsx has some caveats. Most importantly that most vue builtin directives are not supported (for example, v-for, v-model, etc.), expect for v-show. Some of them can be implemented manually, but v-model for example is kind of a pain in the ass.

There's this though:

Also the sourcemap result is kind of crappy, things like @ are not mapped correctly, I resorted to just using 'eval' as webpack config.devtool, it's good enough for what I'm doing.

Instructions

# vcap.me is a wildcard domain that resolves to localhost
# in case you need to pass URL's around from browser to 
# containers this could help you get around localhost problem

services:

Adding TypeScript to a Rails + Webpacker + Vue project

These instructions assume you already have a Rails 5.2 project using Webpacker 4 with Vue 2 and Vuex 3. I'll show you how to add TypeScript to the project, and type-safe your Vue components, including single-file components (SFCs). This document will not teach you TypeScript syntax or type theory. It also assumes your code already works without TypeScript. You shouldn't use this article to, for example, get started with Vuex, because I'm leaving out lots of necessary boilerplate code and focusing just on TypeScript changes.

If you want to see a commit on a project accomplishing this migration, visit https://github.com/RISCfuture/AvFacts/commit/666a02e58b4626a074a03812ccdd193a3891a954.

Setup

1. Run rails webpacker:install:typescript. This should modify config/webpacker.yml and config/webpack/environment.js (leave those changes), add tsconfig.json and config/webpack/loaders/typescript.js (leave those files), and add some other files in `a
