Extend AWS Error

NPM Version Build Status dependencies Status

AWS SDK for JavaScript throws an error without the request information, therefore we are too difficutl to investigate where the problem occurred at debug. This npm module extends an AWS Request error with the method name, the place where it ran and so on. It supports only requests with callback and promise requests, does not support the process using readable stream.

Install

$ npm install extend-aws-error

How to use

const extendAWSError = require('extend-aws-error');

extendAWSError( options )

  • options <Object>
    • noRunStack <Boolean> If it is true, the run stack is not outputed. Defaults to false
    • runStackLines <Number> Specify run stack lines outputed. Defaults to 3
    • paramsInspectOptions <Object> Specify the options to inspect request params. Defaults to { showHidden: true }
    • AWS <AWS> For test. if not specified, load aws-sdk automatically.

Example

const AWS = require('aws-sdk');
require('extend-aws-error')({ AWS }); // must be defined only once in your whole application

/*
 * alternative short method if your application is only 1 file
 *
 * const AWS = require('extend-aws-error')();
 */

const s3 = new AWS.S3({ region: 'ap-northeast-1' });
s3.getObject({
  Bucket: 'BucketNotExists',
  Key: 'KeyNotExists'
}, (err, data) => {
  console.log(err.stack); // The result is outputed by the following

  const dynamodb = new AWS.DynamoDB({ region: 'ap-northeast-1' });
  dynamodb.getItem({
    Key: {
     "Artist": {
       S: "Acme Band"
      }
    }, 
    TableName: "Music"
  }).promise()
  .catch(err => {
    console.log(err.stack); // The result is outputed by the following
  });
});

console.error(err.stack) examples

The heading is AWS Request failed: <endpoint>.<method>(<params>). If the options.noRunStack is not true, The run stack is appended after it. The cost of outputing a run stack is high, so recommending to define { noRunStack: process.env.NODE_ENV === 'production' } so as to be disabled in production. The number of the run stack lines can be changed by options.runStackLines that is default 3.
