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).

TypeScript and currying

TypeScript and currying

In functional programming you often want to apply a function partly. A simple example is a function add. It would be nice if we could use add like:

var res2 = add(1, 3); // => 4

var add10To = add(10);
var res = add10To(5); // => 15

Solving "one database per user" in CouchDB/IrisCouch/Cloudant

Background

Security in a single CouchDB can only be set up to do either:

  • Everyone can read/write everything (admin party)
  • Everyone can read, some can write
  • Some can read everything, and those same people can write everything

So in the very common situation where you want user data to be private, the current best practice is to give every user a database. This sounds nuts at first, but it turns out that databases are cheap in CouchDB; Cloudant boasts that 100k databases in a single Couch is not uncommon (source).
