🎒 Requierments

To use this package you will need:

• NodeJS

🚀 Quickstart

Install

npm install @danielcobo/catcher

Note: In case you're wondering, @danielcobo/ is just a namespace scope - an NPM feature. Scopes make it easier to name modules and improve security.

Require the module

const err = require('@danielcobo/catcher');

Example use

const result = await trySomething(param).catch(
  err('Everyone fails sometime. Error:')
);

For details see documentation below.

📘 Documentation

🆘 Troubleshooting

Only works in NodeJS since it will also exit process.
