Non-deterministic module ordering is an even bigger footgun

Update – in the comments below, @bmeck clarifies that statically imported modules do evaluate in a deterministic sequential order, contra the Hacker News comments that prompted this gist.

Another follow-up to Top-level await is a footgun. On the Hacker News comments, Domenic says this:

(The argument also seems to be predicated on some fundamental misunderstandings, in that it thinks everything would have to be sequentialized. See my other replies throughout this thread.)

In other words, if you have an app like this...

Sequelize: Step-By-Step

Sequelize is a powerful library in Javascript that makes it easy to manage a SQL database. Sequelize can layer over different protocols, but here we'll use PostgreSQL. At its core, Sequelize is an Object-Relational Mapper – meaning that it maps an object syntax onto our database schemas. Sequelize uses Node.JS and Javascript's object syntax to accomplish its mapping.

Under the hood, Sequelize used with PostgreSQL is several layers removed from our actual database:

1. First, we write our Sequelize, using Javascript objects to mimic the structure of our database tables.
2. Sequelize creates a SQL string and passes it to a lower-level library called pg (PostgreSQL).
3. pg connects to your PostgreSQL database and queries it or transforms its data.
4. pg passes the data back to Sequelize, which parses and returns that data as a Javascript object.

Auto-Deploying via Travis CI

Because Travis CI can automatically execute scripts after successfully (or unsuccessfully!) executing tests, it is an obvious choice for a deployment tool. In order to deploy to a Git repository on a remote server, the process generally is as follows:

• Set up SSH keys
• Add the server's copy of the repository as a Git remote
• Push to the remote
• SSH into the server and execute any installation/compilation/miscellaneous commands

Before even touching .travis.yml...

This is a fork of original gist https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e, with slight changes on pointing to 5.7 version branch, instead of 8 (latest default of MySQL in Hombrew).
