stdError

A small express middleware for standardizing on errors, it includes a few error types and more are easily added

Purpose

At i.TV, we tend to do error handling from the server lots of different ways, here is how we standardize on it

Usage

var e = require("std-error")

return next(new e.NotFound())
...
app.use(function(err, req, res next) {
  res.json(err.statusCode, {error: true, message: err.message})
})

// or, which is the the same as above (works for express 2.0 and 3.0)
app.use(e.defaultHandler) //express 3.0
app.error(e.defaultHandler) // express 2.0

// Register custom errors

e.register({type: "MyError", message: "Something bad happened", statusCode: 9000})

// Register custom error with a custom errorCode

e.register({type: "MyErrorWithErrorCode", message: "Something bad happened", statusCode: 500, errorCode: 1000})

return next(new e.MyError())

// change default status codes
e.NotFound.prototype.statusCode = 405

  {type: "BadParameter", message: "Invalid parameter in request", statusCode: 400},
  {type: "Unauthorized", message: "Missing or Invalid credentials", statusCode: 401},
