CLJS in AWS Lambda Quick Start

Setup

First, a few dependencies:

1. Leiningen: https://leiningen.org/
2. Node.js & NPM: https://nodejs.org/
3. Serverless: https://serverless.com/
4. An active AWS account: https://aws.amazon.com/

ClojureScript master now has cljs.core/eval. This delegates to cljs.core/*eval* which, by default throws, but you can bind it to any implementation that can compile and evaluate ClojureScript forms.

If you require the cljs.js namespace (which is the main support namespace for self-hosted ClojureScript), then cljs.core/*eval* is set to an implementation that uses self-hosted ClojureScript for this capability. This means that all self-hosted ClojureScript environments will now have a first-class eval implementation that just works. For example, Planck master:

$ planck -q
cljs.user=> (eval '(+ 2 3))

Prerequisites

You'll need to have a system running that is accessible through a DNS record. It should have access to the public Habitat depot, https://app.habitat.sh so it can download the required packages.

You'll need to register an OAuth application for GitHub. You need the client ID and client secret that are created for the application later in this guide. Your system needs to have access to https://github.com so that it can authenticate.

Your system also needs to have an FQDN that can be resolved, for example depot.example.com. This will be used in your OAuth application's "Authorization Callback URL." For this example, use http://depot.example.com/#/sign-in. The /#/sign-in is required.
