Echo JS 0.11.0

Venturing OT, but if you're doing end to end tests, I would suggest getting familiar with Docker, docker-compose and its' usage.  It's very easy to stand-up your entire environment, run your tests, and stand-down said environment.  Many CI/CD runners have a full docker environment available, so this makes integration super easy as well.

Somewhat surprised Intl isn't in the box, or at least a built-in option, on this one.

It may also be worth either looking into or hand-crafting a tool using the BigInt[1] (Int64) data type, with a fixed precision. Also, worth following the Decimal/BigDecimal proposal[2]

I wouldn't suggest using this library/approach.  First, read/write in your application directory is begging for trouble.  Second, it's using an array lookup instead of an object/map.  Third, it's not very flexible.

TLDR; 

Use Promise.all for parallel async operations.

    const [a, b, c] = await Promise.all([p1, p2, p3]);

For more/similar details, these two books from Steve Souders are good reads, and very relevant.

2. Even Faster Web Sites

Alternatively to using Firebae... Self-hosting CockroachDB, FaunaDB, Cloudflare KV+Workers, Azure Storage Tables, DynamoDB and other databases behind an API or Cloudflare Workers are some other options as well for backend storage.
