Error handler for either throwing locally or sending a bug ticket to a rest api

$ npm install err-hndlr

const errHndlr = require( "err-hndlr" );

errHndlr.init(
  process.argv[2] === "--debug",
  "https://api.jneidel.com/errors/submit",
  {
    applicationId: "1337"
  }
)

errHndlr.throw(
  "smt went wrong",
  {
    env: {...},
  },
  false
)

// If --debug flag was passed:
//=> Error: something went wrong

// If --debug flag was not passed:
// POST https://api.jneidel.com/error/submit
//    {
//      applicationId: "1337",
//      error: {
//        msg: "smt went wrong",
//        stack: "...",
//      },
//      env: {...},
//    }
