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

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

Access to Ameritrade API

notes that may be helpful for node.js devs

What I've gathered is authorization tokens must be earned first. Authorization tokens are good for three months, once you are setup, you will get two tokens which come as long strings, An access_token and a refresh_token. Access tokens are only valid for 30 minutes so you will need to code to refresh the session using the refresh token frequently. When you refresh, you are given a new access token and that is what you use to "login" or pull from the api for the next period. But in order to get the tokens, you will be required to go through some processes to get a valid token that applies to your app. The following text kind of steers you in that direction...

Making an app

On the api site you will need to make an app, where you pick some random name by using some random numbers. It should be automatically generated but it isnt. For this field item, I simply went to https://www.uuidgenerator.net/ and just grabbed the firs

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Supported built-in functions

abs(float) - Returns the absolute value of a given float. Example: abs(1) returns 1, and abs(-1) would also return 1, whereas abs(-3.14) would return 3.14. See also the signum function.
basename(path) - Returns the last element of a path.
base64decode(string) - Given a base64-encoded string, decodes it and returns the original string.
