Pretty Errors

Just because they are errors doesn't mean they can't be pretty.

Installation

    npm install pretty.errors

Usage

throw new PrettyError

Pretty Errors extends the Error class and so it can be thrown as such. However, the Pretty Errors constructor accepts three arguments:

• Message (String) The message property is the string description of the error.
• Name (String) The name property is a string label that identifies the error.
• Code (String) The code property is a string label that identifies the kind of error.

By passing it to the constructor, it automatically assigns it.

Moreover, if you wish to create your own custom errors for your app, you can make it pretty by extending the Pretty Errors class.

Example

    let PrettyErrors = require("pretty.errors");

    ...
    throw new PrettyErrors("Something bad occoured", "Really bad error". 500);
    ...

Throw a specific error

Pretty Errors class has a special static method called throw(). This method accepts an Error class, makes it pretty and exits the process. So, if you need to throw a especific error, you can still make use of all this beauty:

    let PrettyErrors = require("pretty.errors");
    
    try {
        require('url').parse(() => { }); // throws TypeError, since it expected a string
    } catch(e) {
        PrettyErrors.throw(e);
    }
