Seabed

A sturdy base for web projects. Seabed is built on the philosophy that you should have full visibility and control over your development and build process, while keeping a set of base configurations and shared components between projects. You are encouraged to thouroughly read the generated configuration files.

This project was created as a common environment for Fractal web applications.

Requirements

• Node >= 10.13
• Yarn

Browser support

• last 2 versions
• > 1%

Based on

• dotenv
• webpack
• babel
• react
• eslint
• scss
• stylelint
• postcss
• linguijs
• jest
• react-testing-library
• svgo
• circleci

How it works

Add Seabed to your project with yarn add @fractal/seabed.

yarn run seabed init to initialize your project with Seabed's default configurations. Any previously existing files will be compared, and their replacement confirmed.

Assumptions

You must create and maintain your own package.json file. These are the recommended scripts for development, building, testing, and i18n management.

{
  "scripts": {
    "start": "webpack-dev-server --config webpack.development.js",
    "lint": "eslint src test",
    "stylelint": "stylelint src/styles",
    "test": "yarn i18n-compile && TZ=UTC NODE_ENV=test jest test",
    "test:es-check": "yarn i18n-compile && dotenv -e .env.test yarn build && es-check es5 build/*.js",
    "build": "NODE_ENV=production webpack -p --config webpack.production.js",
    "test-build": "yarn i18n-compile && yarn build && node production-configuration-server.js",
    "i18n-add-locale": "lingui add-locale",
    "i18n-extract": "lingui extract",
    "i18n-compile": "lingui compile"
  },
}

Components

Usage of these components assumes that peerDependencies are installed:

• react
• react-dom
• prop-types
• classnames

Provided components

common

• Confirmation (uses Modal internally)
• DropdownMenu
• Modal
• ExternalLink

fields (for redux-form)

• [] Checkbox
• [] Input
• [] RadioGroup
• [] Textarea

CSS

Each of the available stylesheets is built with theming and customization in mind. We use CSS custom properties to achieve this. The available properties for each of the stylesheets are defined under :root.

For maximum compatibility with mobile devices, a --mobile-viewport-height is used on "fullscreen" mobile components, like Modal. This properties defaults to 100vh if not defined.

base.scss

import "@frctls/seabed/dist/base.scss"
