Better Errors #12

Open Ellisande opened 8 years ago

Ellisande commented 8 years ago

What kind of issue is this? (bug, feature, etc)

Feature

What is the proposed change?

Change places where it is currently using new Error to use a new error class. The goal is to provided very detailed errors.
In addition to the error itself each error should tell the consumer common things that cause the error.
Each error message should be very well formatted and readable.
Stack traces should be accurate and readable
What was the old behavior, if any?

It just news up the JavaScript error object and passes a message

Why will this be beneficial?

It will help the consume identify if they are not using the APIs correctly.

Misc. info

Thoughts for a starter:

class UndefinedThenError extends Error {
    constructor(){
      super();
      this.likelyReasons = likelyReasons;
      this.message = straightErrorMessage + likelyReasons + prettyFormatting
    }
}
