# AMP-transformer

This repository contains a go/WASM port of the [AMP packager transform library](https://github.com/ampproject/amppackager/tree/master/transformer). It is derived from Devin Mullin's work towards minimizing the Go WASM runtime so Go/WASM binaries can be run within CF Workers' 128-MB heap memory limit.

## Building the AMP transformation

You'll need to compile a separate branch of Go that contains changes to the runtime such that

the amount of heap memory used can reasonably fit in a worker.

```bash

git clone https://github.com/gabbifish/go

cd go/

git checkout gabbi-small

src/make.bash

```

Then use it to build the wasm binary from worker.go:

```bash

cd go-wasm/

GOOS=js GOARCH=wasm path/to/custom-go/bin/go build -o main.wasm main.go

```

Upload the wasm to Cloudflare Workers with name `TRANSFORM_WASM`.

## Building for Workers

First, make sure to pull node dependencies:

```bash

npm install

```

then, to build for workers, run 

```bash

npm run build

```

The final outputted workers code is in the `dist/` directory. There is a fully minified and less minified version of the code, so you can debug the code in the workers console using the less minified version before deploying the fully minified version.

## Todo:

1. Set up makefile with nice API calls for easily uploading the worker and the wasm binary.
