```
## Usage
```js
import cleanStack from 'clean-stack';
const error = new Error('Missing unicorn');
console.log(error.stack);
/*
Error: Missing unicorn
at Object. (/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)

## API
### cleanStack(stack, options?)
Returns the cleaned stack or `undefined` if the given `stack` is `undefined`.
#### stack
Type: `string | undefined`
The `stack` property of an [`Error`](https://github.com/microsoft/TypeScript/blob/eac073894b172ec719ca7f28b0b94fc6e6e7d4cf/lib/lib.es5.d.ts#L972-L976).
#### options
Type: `object`
##### pretty
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`
##### basePath
Type: `string?`
Remove the given base path from stack trace file paths, effectively turning absolute paths into relative ones. It will also transform absolute file URLs into relative paths.
Example with `'/Users/sindresorhus/dev/clean-stack'` as `basePath`:
`/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15` → `unicorn.js:2:15`
##### pathFilter
Type: `(path: string) => boolean`
Remove the stack lines where the given function returns `false`. The function receives the path part of the stack line.
```js
import cleanStack from 'clean-stack';
const error = new Error('Missing unicorn');
console.log(cleanStack(error.stack));
// Error: Missing unicorn
// at Object. (/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15)
// at Object. (/Users/sindresorhus/dev/clean-stack/omit-me.js:1:16)
const pathFilter = path => !/omit-me/.test(path);
console.log(cleanStack(error.stack, {pathFilter}));
// Error: Missing unicorn
// at Object. (/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15)
```
