Sample app to generate compile ClojureScript to NodeJS module

The output can be used in AWS Lambda, and in general as a Node.js module.

Compile with Clojure

clj -m cljs.main --target node --optimizations advanced -c hello-world.core

The above generates the out/ directory which will contain the main.js file.

Compile with Lumo

An alternative way to compiling ClojureScript is using Lumo.

# Download Lumo Docker image or install it on your system
docker pull anmonteiro/lumo:latest

# Compile command
docker run -v `pwd`:`pwd` -w `pwd` --rm -it anmonteiro/lumo --classpath src ./build.cljs

# The Docker user by default is root so fix the ownership
sudo chown -R `id -u`:`id -u` main.js

This will compile the CLJS code and generate the out/main.js, as defined in build.cljs, which is the same as the one compiled by Clojure.

Create the AWS Lambda bundle

./build-tools/lambda_bundle.sh

Creates the build/ directory which will contain the lambda bundle zip.
