Returns the cleaned stack or undefined
if the given stack
is undefined
.
stack
Type: string | undefined
The stack
property of an Error
.
options
Type: object
pretty

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.

→ unicorn.js:2:15
pathFilter

Remove the stack lines where the given function returns false
. The function receives the path part of the stack line.
import cleanStack from 'clean-stack';
const error = new Error('Missing unicorn');
console.log(cleanStack(error.stack));
// Error: Missing unicorn
// at Object.<anonymous> (/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15)
// at Object.<anonymous> (/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.<anonymous> (/Users/sindresorhus/dev/clean-stack/unicorn.js:2:15)
