Anyaral

This is the codebase for the Anyaral Toolbox web app. It's a reference app for World of Twilight, a table top skirmish war game.

Built with

Developing

Pull requests are welcome. For anything other than bug fixes, please open an issue first to discuss what you would like to change.

Requirements

  • Node.js version 12 or later
  • Yarn version 3

How to run

Install the dependencies:

yarn

Then run the development server:

yarn dev

Open http://localhost:3000 with your browser to see the result.

PWA precaching

next-pwa doesn't perform precaching in development mode, so in order to test PWA precaching you need to build the production version.

  1. Build the production version
yarn build
  1. Run the production server
yarn start
  1. Test on http://localhost:3000

Yarn Plug'n'Play

Using Plug'n'Play is frustrating at times because not all libraries and tools are fully compatible.

Extra Dependencies

Some devDependencies are present in package.json purely to fix PnP issues with some libraries.

For next-pwa:

  • @babel/core
  • babel-loader

For jest:

  • @babel/runtime
Yarn warnings

Yarn install produces some warnings related to webpack. This is due to next-pwa not being PnP-ready (and our babel-loader fix).

The warnings are left on purpose. Webpack is provided by Next.js and there is no point in providing another version, which might or might not be the same, just for the sake of getting rid of warnings.

Getting rid of warnings would mean adding webpack as a dependency in package.json for the anyaral warning and as a packageExtension in .yarnrc.yml for the next-pwa warnings. Then we'd potentially have 3 versions of Webpack. It's very brittle.

Strictly speaking, Next.js should specify webpack as a peer dependency, which the app would provide, with Yarn raising a warning if the version is incompatible.

Once this is done, we'll also need next-pwa to specify webpack as a peer dependency.

Until this happens, the warnings stay.

ESLint integrations

In order to make the ESLint extension for VS Code work, you need to run:

yarn dlx @yarnpkg/sdks vscode

For other editors, refer to https://next.yarnpkg.com/getting-started/editor-sdks.

Reverting to node-modules mode

If you add a library and you can't make it work with PnP, you can always revert to node-modules mode. That's the mode the production server uses anyway.

To revert to node-modules mode:

  1. Edit the nodeLinker option in .yarnrc.yml
nodeLinker: node-modules

Note that node-modules is written with a dash, not an underscore.

  1. Generate the node_modules folder
yarn install

Things to keep in mind before making changes

This responsive app is designed with progressive enhancement and accessibility in mind. Please respect those constraints.

Responsive web design

All pages should adapt to the screen width. Users can access the app on mobile, tablet or desktop.

Progressive enhancement

  • The website works with JavaScript disabled
  • Enabling JavaScript uses NextJS's optimisations such as client-side navigation and prefetching
  • On platforms that support PWA, the website works offline and can be installed as a stand-alone app

Accessibility

The website should be as accessible as possible. The approach is to:

  • Use semantic HTML systematically
  • Research best practice: Not all commonly used solutions are accessible.
  • For CSS
    • colours: should have enough contrast, ideally AAA, at least AA
    • font size: user preferences should be respected
  • Test keyboard navigation
  • Test with a screen reader
