Usage

For more use-cases see the tests

const cleanStacktrace = require('clean-stacktrace')

API

cleanStacktrace

Removes mostly not needed internal Nodejs entries. If you pass mapper function, you can make more changes to each line of the stack - for example making the paths to be relative, not absolute.

Params

  • stack {String}: an error stack trace
  • mapper {Function}: more customization for each line
  • returns {String}: modified and cleaned stack

Example

var cleanStack = require('clean-stacktrace')
var 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)
 
// or making paths relative
var path = require('path')
var stack = clean(error.stack, (line) => {
  var m = /.*\((.*)\).?/.exec(line) || []
  return m[1] ? line.replace(m[1], path.relative(process.cwd(), m[1])) : line
})
// =>
// Error: Missing unicorn
//     at Object.<anonymous> (unicorn.js:2:15)

Contributing

Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.
Please read the contributing guidelines for advice on opening issues, pull requests, and coding standards.
If you need some help and can spent some cash, feel free to contact me at CodeMentor.io too.

In short: If you want to contribute to that project, please follow these things

  1. Please DO NOT edit README.md, CHANGELOG.md and .verb.md files. See "Building docs" section.
  2. Ensure anything is okey by installing the dependencies and run the tests. See "Running tests" section.
  3. Always use npm run commit to commit changes instead of git commit, because it is interactive and user-friendly. It uses commitizen behind the scenes, which follows Conventional Changelog idealogy.
  4. Do NOT bump the version in package.json. For that we use npm run release, which is standard-version and follows Conventional Changelog idealogy.

Thanks a lot! :)

Building docs

Documentation and that readme is generated using verb-generate-readme, which is a verb generator, so you need to install both of them and then run verb command like that

$ npm install verbose/verb#dev verb-generate-readme --global && verb

Please don't edit the README directly. Any changes to the readme must be made in .verb.md.

Running tests

Clone repository and run the following in that cloned directory

$ npm install && npm test
