attempt-export

Safely run a function and export its return value, or undefined if it throws.

Installation

npm install attempt-export

Usage

For example, if you want to make a file that exports Symbol if it exists, otherwise undefined:

const attemptExport = require("attempt-export")(module)
const assert = require("assert")

attemptExport(() => {
  assert(Symbol.species.constructor === Symbol)
  return Symbol
})
