halogen-boilerplate

This is a boilerplate for starting a real world project using the purescript-halogen library for declarative user interfaces.

Features

• Bootstrap 4.1.2 is included.
• Update to latest purescript-halogen (only psc-package)
• psc-package is included and it is default
• A rational structure of project with routing.
• Webpack is optional.

Prerequisites

This guide assumes you already have Git and Node.js installed with npm somewhere on your path.

npm install --global purescript pulp psc-package

Getting started

First clone the repo and step into it:

git clone https://github.com/jimmyhuco/halogen-boilerplate.git hello-halogen
cd hello-halogen
psc-package install

Building

The project can now be built with:

npm run build

This will build the PureScript source code and produce a bundled JS file as dist/js/app.js.

If you open dist/index.html you should now have a basic working Halogen app.

You can also use the command:

npm run watch

To start a process that will watch the source files and trigger a reload whenever they are modified. Alternatively...

Fast watching with purs ide

If you're using an editor that supports purs ide, there's an option for getting near-instant builds of the app while you work on it:

npm install
npm run watch-fast

First, you should have to install Webpack, and then it will start a watch process to rebundle the app whenever the output files are changed. Since purs ide rebuilds modules on save, this means you can use this much faster bundle-only rebuild script.

Note

• purescript-halogen-bootstrap don't include bootstrap4, so I just add some "demo code" to use bootstrap4.
• Demo images are all from unsplash.com.
• I learned "watch-fast" from purescript-halogen-template
• Thank you @snackycracky. He update purescript from 0.11.6 to 0.12.
