I'm using Gulp to compress a zip file and then upload it to AWS Lambda. The upload zip file is done manually. Only the process of compressing is handled by Gulp.

Here is my gulpfile.js

var gulp = require('gulp');

var zip = require('gulp-zip');

var del = require('del');

var install = require('gulp-install');

var runSequence = require('run-sequence');

var awsLambda = require("node-aws-lambda");

gulp.task('clean', function() {

  return del(['./dist', './']);


gulp.task('js', function() {

  return gulp.src('index.js')



gulp.task('npm', function() {

  return gulp.src('./package.json')


    .pipe(install({production: true}));


gulp.task('zip', function() {

  return gulp.src(['dist/**/*', '!dist/package.json'])




gulp.task('deploy', function(callback) {

  return runSequence(


    ['js', 'npm'],





After running the deploy task, a zip folder named is created consists of an index.js file and a node_modules folder. The node_modules folder contains only a lodash library.

This is index.js

var _ = require('lodash');

console.log('Loading function');

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

    //console.log('Received event:', JSON.stringify(event, null, 2));

    var b = _.chunk(['a', 'b', 'c', 'd', 'e'], 3);


    callback(null, event.key1);  // Echo back the first key-value

    //callback('Something went wrong');


After using AWS lambda console to upload the folder. There is an error showing that the lodash library cannot be found


  "errorMessage": "Cannot find module 'lodash'",

  "errorType": "Error",

  "stackTrace": [

    "Function.Module._load (module.js:276:25)",

    "Module.require (module.js:353:17)",

    "require (internal/module.js:12:17)",

    "Object.<anonymous> (/var/task/index.js:1:71)",

    "Module._compile (module.js:409:26)",

    "Object.Module._extensions..js (module.js:416:10)",

    "Module.load (module.js:343:32)",

    "Function.Module._load (module.js:300:12)",

    "Module.require (module.js:353:17)"



But in the zip folder, there is a node_modules directory that contains the lodash lib.


    |--- lodash


When I zip the node_modules directory and the file index.js manually, it works fine.

Does anyone have an idea what is wrong? Maybe when compressing using Gulp, there is a misconfigured for the lib path?

This worked fine:


    .src(['sourceDir/**'],         {nodir: true, dot: true} )



This is the 2nd parameter of the above:

{nodir: true, dot: true}

We have to include dotfiles for the ZIP (ex: .exe, .config, .whatever)
