# What is this project

Its an insecure FaaS essentially, you can host your random snippets of code on here.  

Just make sure that it isnt security critical code.  

I have some security going on however, I have only allowed the http and net modules on here. Please let me know if other modules are required, I can write mock interfaces for fs if needed.

## Creating a function

Submit a POST request to http(s)://host/api/create that follows the JSON spec below

```javascript

{

    "source" "This is where a string representation of your source code should go, this source code MUST contain a module.exports to a fucntion that has two parameters, req: the express js request object and cb: the callback to return after execution of code."

}

```

Here is an example

```javascript

{

	"source": "module.exports = function(req, callback) { callback({data: 'hello' }); }"

}

```

This will return a json in this format

```javascript

{

  "message": "Created function {sha256_hash_of_source_code_after_beautify}"

}

```

an example for sha256_hash_of_source_code_after_beautify = 00867e8f59188a3a6081f538a8acd9246b3250df7bf56cce211fa2cb27bdc610 is

```javascript

{

  "message": "Created function 00867e8f59188a3a6081f538a8acd9246b3250df7bf56cce211fa2cb27bdc610"

}

```

## Testing a function

Perform any http request to the endpoint http(s)://host/:sourceHash  

The req body from the server itself is passed onto the sanboxed function.  

For the above example we could do a GET to http(s)://host/00867e8f59188a3a6081f538a8acd9246b3250df7bf56cce211fa2cb27bdc610
