AMP-transformer

This repository contains a go/WASM port of the AMP packager transform library. 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.

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:

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:

npm install

then, to build for workers, run

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.
