Current behavior

When building a nestjs application on Zeit Now v2, anything that uses require('optional') doesn't work properly.

Due to how the builders work, require never gets transpiled into a webpack compatible require (e.g. __webpack_require__(7394)), so the package isnt found, and optional('type-graphql') (for example) always returns null

Expected behavior

Avoid using the optional package

Minimal reproduction of the problem with instructions

Spin up a zeit now v2 app, using the node-server builder, with now dev

[cryptiklemur]

Problem stems from optional not allowing for static analysis, and not being included in a webpack build
