Fast CouchDB setup in AWS

Fast CouchDB setup in AWS

CouchDB is a NoSQL database for storing JSON documents. It comes with a REST API out of the box so your client applications can persist data while requiring you to write little or no server-side code. CouchDB's killer feature is its ability to easily replicate, which allows for horizontal scaling, easy backup, and for client adapters to synchronize documents. This is perfect if you want to write an application that is offline-first. It's become my go-to database when creating new

tracked npm

@tracked is a decorator for Preact that makes working with state values no different than properties on your component instance.

It's one 300 byte function that creates a getter/setter alias into state/setState() for a given key, with an optional initial value. The "magic" here is simply that it works as a property decorator rather than a function, so it appears to integrate directly into the language.

tracked has no dependencies and works with any component implementation that uses this.state and this.setState().

// Promise.resolve is good for wrapping synchronous code

ESLint Reset - A starter .eslintrc file that resets all rules to off and includes a description of what each rule does. From here, enable the rules that you care about by changing the 0 to a 1 or 2. 1 means warning (will not affect exit code) and 2 means error (will affect exit code).

Liberal, Accurate Regex Pattern for Matching Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502
