Neat-errors NPM

Neat Errors for NodeJs

This is a really neat error reporter for NodeJS, featuring code extraction, stack cleaning, syntax highlighting and tweakable output out-of-the-box.

Usage

Easiest way is to require neat-errors/register at the top of your application entry point:

import "neat-errors/register";

// do your stuff here ...

If not possible in your case, then you can use the full programmatic API:

import Neat from "neat-errors"

const neat = new Neat()

process.on('uncaughtException', e => {
  console.error(neat.render(e));
  process.exit(1);
})

Unless specified manually, neat-errors will check for the following options in process.argv and adapt its behaviour accodingly:

--full-stack-trace: do not clean the stack trace before rendering
--print-all-code print a code excerpt for all call sites in the stack trace

Other than that, the following arguments can be supplied to Neat as an options object:

cwd: current working directory to make paths relative to.
printAllCode: defaults to checking process.argv for its value
fullStackTrace: defaults to checking process.argv for its value
