Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

// How to use?
// 1. Create `sequelize-schema-file-generator.js` in your app root
// 2. Make sure you've ran the `sequelize init` before (It should create `config`,`seeders`,`migrations` folders).
// 3. Update `DATABASE_DSN` below to match your connection string (works with any database adapter that Sequelize supports)
// 4. Run it with `node sequelize-schema-file-generator.js`
// 5. Review the generated migrations inside of the `migrations` folder.

Setting up geth as a service under systemd Fedora 27

Prerequisite: dnf install golang

1. Create user geth with useradd
2. As user geth fast sync the blockchain, geth --fast --cache 1024
3. Manually run geth --rpc as user geth and watch to see that the blockchain continues to sync properly
4. Install the geth.service file (also in this gist) in /usr/lib/systemd/system/
5. Make a symlink from /etc/systemd/system/multi-user.target.wants/geth.service to /usr/lib/systemd/system/geth.service

Regular Event Loop

This shows the execution order given JavaScript's Call Stack, Event Loop, and any asynchronous APIs provided in the JS execution environment (in this example; Web APIs in a Browser environment)
