purescript-halogen-nextjs

A server side rendering framework for purescript-halogen, like next.js is a framework for react, written fully in purescript.

It is using not yet published features/packages:

• purescript-halogen/purescript-halogen-vdom#38
• purescript-halogen/purescript-halogen#671
• https://github.com/srghma/webpack-spago-loader

Features:

1. js and css is split per page using webpack machinery
2. when Nextjs.Lib.Link.component appears in the viewport - the page dependencies are prefetched
3. on initial rendering the Nextjs.Lib.PageSpecBoxed.PageData__Dynamic is fetched on server side and result in inserted into the page into the <script id="__PAGE_DATA__">JSON<script>

How it works

1. How to run it?

yarn dev

or

yarn build && yarn serve

2. Where pages are stored?

PageSpecBoxed is a top level purescript file in the packages/client/pages directory (e.g. packages/client/pages/Foo.purs)

PageSpecBoxed should export the page :: PageSpecBoxed object (which is a PageSpec object, but with existentially hidden input type argument)

3. What is a meaning of .deps.js files?

If there is a file in the packages/client/pages/ directory ending with .deps.js (e.g. packages/client/pages/Foo.deps.js) - it will be required before the page is loaded

(Check createClientPagesEntrypoints.js and isomorphic-client-pages-loader to see how it works)

You can use packages/client/pages/Foo.deps.js to add per page css files (it's just for splitting css, the css is global, i.e. the <link rel="stylesheet" ...> element is not removed after you go to the some other page)

Or You can use it for adding per page js dependencies (like ace npm package, that will be loaded only for Ace.purs page)

4. Where can I define global css and js?

In the client.entry.css and client.entry.js

TODO:

• Finish https://github.com/srghma/generate-halogen-css-modules to generate FFI for css files ending with .module.css
• yarn dev should also reaload when css file in app dir changes
• PWA with service worker https://pursuit.purescript.org/packages/purescript-workers/ using workbox-webpack-plugin
• An example with cookies authentication and secure page
• Move reusable parts into the separate package, publish to pursuit and npm
• https://www.npmjs.com/package/livereload and custom https://www.npmjs.com/package/webpack-livereload-plugin for dev
• update "title" on client when user visits new page
