Node.js error object for streamlined errors using AWS Lambda and API Gateway

AWS Lambda Error

If you plan to use Node.js in an AWS Lambda function with an AWS API Gateway and need to have streamlined error objects for easy response parsing, just use lambda-error:

var lambdaErr = require('lambda-error');

exports.handle = function(e, ctx, callback) {
  if (!e.name) {
    return callback(
      lambdaErr.BadRequest('Missing name').toString()
    );
  }
  
  ctx.succeed({name: e.name, found: true});
};

var lambdaErr = require('lambda-error');

exports.handle = function(e, ctx, callback) {
  if (!e.name) {
    return callback(
      lambdaErr.BadRequest('Missing name').withContext(ctx).toString()
    );
  }
  
  ctx.succeed({name: e.name, found: true});
};
