Question

We are working on a project/framework that aids in deploying and maintaining code in AWS Lambda. I want to build/bundle all node.js code for a lambda function into one js file b

aws-sdk-js now officially supports browserify. You can why this is a great thing on my blog.

I have created a serverless plugin called serverless-plugin-browserify that will do all the heavy lifting with very minimal configuration.

To answer the question specifically, I solved the problem with this browserify config:

{
  disable: false, //Not an official option, used as internal option to skip browserify
  exclude: [],    //Not an option, but will use for setting browserify.exclude() if defined in yml
  ignore:  [],    //Not an option, but will use for setting browserify.ignore() if defined in yml

  basedir:          this.serverless.config.servicePath,
  entries:          [],
  standalone:       'lambda',
  browserField:     false,  // Setup for node app (copy logic of --node in bin/args.js)
  builtins:         false,
  commondir:        false,
  ignoreMissing:    true,  // Do not fail on missing optional dependencies
  detectGlobals:    true,  // We don't care if its slower, we want more mods to work
  insertGlobalVars: {      // Handle process https://github.com/substack/node-browserify/issues/1277
    //__filename: insertGlobals.lets.__filename,
    //__dirname: insertGlobals.lets.__dirname,
    process: function() {
    },
  },
  debug:            false,
}
