AWS API Gateway Errors

A set of Error objects mapping directly to error level HTTP status codes.
Built for usage within the AWS API Gateway.

The toString method of each object produces a String which starts with the numeric HTTP status code. These Strings, when sent to a Lambda context's fail method, can be mapped to HTTP status codes within the Gateway. For instance, 404* would map to status code 404.

Usage

npm install --save aws-api-gateway-errors

const errors = require( 'aws-api-gateway-errors' );

function processEvent( event ) {

    ... do something ...

    ... user requested a non-existant resource ...
    throw new errors.NotFound();

}

exports.handler = ( event, context ) => {

    try {
        context.succeed( processEvent( event ) );
    }
    catch( e ) {
        context.fail( e.toString() );
    }

};

There are Error types for all 4xx and 5xx HTTP status codes.
