AWS Lambda exports class not working

Question

I am using NodeJs 6.10.2. I am using 2 files

index.js

var operation = require('./Handler/opHandler').opHandler;

var lambdaHandler = function () {
    var o = new operation();
    o.deleteMessage();
}

exports.lambdaHandler = function(event, context, callback) {
    handleSQSMessages(context, callback);
};

opHandler.js

opHandler = function() {
     this.db = '';
}
opHandler.prototype.deleteMessage = function (receiptHandle, callback) {
    // My code here
    // this.db = 'new val';
}

exports.opHandler = opHandler;

when run index.lambdaHandler on AWS Lambda with NodeJs 6.10, following error occurs

 Syntax error in module 'index': SyntaxError
  at exports.runInThisContext (vm.js:53:16)
  at Module._compile (module.js:373:25)
  at Object.Module._extensions..js (module.js:416:10)
  at Module.load (module.js:343:32)

  at Object.<anonymous> (/var/task/index.js:16:13)
  at Module._compile (module.js:409:26)
  at Object.Module._extensions..js (module.js:416:10)

I have googled and found similar issue here but according to it above code should work in NodeJs 6.10

please paste the full code that you used – Dec 06 '17 at 11:07 — , Dec 06 '17 at 11:07

Try another method or module export. It should work in your case.

index.js

var operation = require('./Handler/opHandler');

var lambdaHandler = function () {
    var o = new operation();
    o.deleteMessage();
}

exports.lambdaHandler = function(event, context, callback) {
    handleSQSMessages(context, callback);
};

opHandler.js

opHandler = function() {
     this.db = '';
}
opHandler.prototype.deleteMessage = function (receiptHandle, callback) {
    // My code here
    // this.db = 'new val';
}

module.exports = opHandler;

It solved my issue may help you out.
