Seeing undefined or null show up in you or ES6 template strings? Instead of printing those literal values, this tagged template literal function will throw errors.

Here is an example with code:

let works = 'works', isNull = null, isUndefined
// The default ES6 behavior is to print the strings "undefined" and "null"
`This ${works} correctly` // Prints "This works correctly"
`This ${isUndefined}` // Prints "This undefined"
`This ${isNull}` // Prints "This null"

// 99.9% of time this is not what I want to happen!
// So tag your literals with `required-template` instead!
const r = require('required-template')

r`This ${works} correctly` // Prints "This works correctly"
r`This ${isUndefined}` // Throws an error
r`This ${isNull}` // Throws an error
