golanglambda

Run the AWS Javascript SDK as a VM in pure Go. It is based on otto as well as ottoext (adapted and vendored for this version).

Building

Make sure you are using Go 1.6 so that the vendor directory is picked up, and do a go install.

Preparing a script

See the sample_s3.js for a test script. Edit it with your own credentials.

You will need to 'browserify' it in order to embed all required modules, which is the next step

Install browserify

See browserify for installation instructions.

Then make sure the modules that you want to use are installed locally. For the sample_s3.js you need to do the following

$ npm install aws-sdk
$ npm install node-uuid

Patch AWS SDK

For now we need to patch the AWS Javascript SDK to use a fetch object instead of the standard XMLHttpRequest object. You can do this as follows:

$ cd node_modules/aws-sdk/lib/http
$ rm xhr.js
$ wget https://raw.githubusercontent.com/fwessels/aws-sdk-js/324d927a278a551264f0d6c2078d852bb7ed2416/lib/http/xhr.js

Browsify a script

After this you can use browserify to prepare your script for running by golanglambda, and we need to make one more modification to prevent an 'old browser' warning (still to be fixed).

$ browserify sample_s3.js | sed 's/= oldBrowser$/= function\(size, cb\) \{ return new Buffer\(size\) \}/' > sample_s3-browserified.js

Run the example

After this you can run your sample:

$ golanglambda sample-s3-browserified.js
