Clean up error stack traces

Removes the mostly unhelpful internal Node.js entries.

Also works in Electron.

$ npm install clean-stack

const cleanStack = require('clean-stack');

const error = new Error('Missing unicorn');

console.log(error.stack);
/*
Error: Missing unicorn
    at Object.<anonymous> (/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15)
    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)
    at Module.load (module.js:343:32)
    at Function.Module._load (module.js:300:12)
    at Function.Module.runMain (module.js:441:10)
    at startup (node.js:139:18)
*/

console.log(cleanStack(error.stack));
/*
Error: Missing unicorn
    at Object.<anonymous> (/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15)
*/

Type: string

The stack property of an Error.

Type: object

Type: boolean
Default: false

Prettify the file paths in the stack:

/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15 → ~/dev/clean-stack/unicorn.js:2:15

Type: string?

Remove the given base path from stack trace file paths, effectively turning absolute paths into relative ones.

Example with '/Users/sindresorhus/dev/clean-stack/' as basePath:

/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15 → unicorn.js:2:15
