purescript-es4x

ES4X bindings for Purescript. For building blazing fast web backends.

Usage

Optional - install GraalVM

You can use either stock JDK, or GraalVM with this. If using GraalVM, the easiest way is to use Jabba.

Clone this repo and cd into it.

git clone https://github.com/ajnsit/purescript-es4x
cd purescript-es4x

Build and run this code -

npm install
npx spago build
npm start

Performance

First impressions of es4x are very positive! My rudimentry and totally unscientific benchmark results for hello world apps in (Purescript+Node), (Purescript+ES4X), and (Haskell+Wai) are below -
