Core values of 🌲 Evergreen

Evergreen is built on the belief that you can never predict all future requirements, only prepare for it. Instead of creating fixed configurations that work today, Evergreen promotes building systems that anticipate new and changing design requirements.

Evergreen is built on the belief that things should work out of the box with smart defaults, but also offer full control when needed. For example, Evergreen uses CSS-in-JS and builds on top of the Box component in ui-box.

Evergreen is built on the belief that using Evergreen and contributing to Evergreen should be a pleasant experience. We prioritize documentation and all the tools for a solid developer experience. We advocate respect and inclusivity in our writings and interactions.

Install and use components πŸ”“

🌲 Evergreen is made up of multiple components and tools which you can import one by one. All you need to do is install the evergreen-ui package:

$ yarn add evergreen-ui
# or
$ npm install --save evergreen-ui

A working version, assuming you are using something like Create React App, might look like this:

import React from 'react'
import ReactDOM from 'react-dom'
import { Button } from 'evergreen-ui'

ReactDOM.render(
  <Button>I am using 🌲 Evergreen!</Button>,
  document.getElementById('root')
)

FAQ

Does Evergreen support theming?

Evergreen currently does not support theming.

Is theming support on the roadmap?

This project is originally build to support the development of product at Segment. This is also the reason theming is not our short term priority. It is on our longer term priority list and hopefully will be supported later in 2018. Expect a clearer roadmap available before that.

Learn more about the theming roadmap

How does Server Side Rendering work?

Evergreen bundles 2 CSS-in-JS solutions, from glamor and ui-box. To make it super easy to do server side rendering and hydration, Evergreen exposes a extractStyles() function that will do SSR for both at once.

Contributing to Evergreen

Step 1. Configuring your editor βš™

If you are using Atom, make sure to install the prettier-atom, linter and linter-xo packages.

All the configuration for prettier and xo is in the package.json. You shouldn't have to configure things separately, please file a issue if there's a problem.

Step 2. Get storybook up and running πŸ“–

To actually start seeing the components you have to run React Storybook:

$ yarn dev

Step 3. Learn more in the Contributing guide πŸŽ“

Please take a look at the contributing guide and roadmap to better understand what to work on.

Scripts explained πŸ€“

Inside the package.json there are a bunch of scripts that this repo uses to run the project in development and to build the project.

Below you can read a description of each script.

yarn dev

Starts the development React Storybook.

yarn test

Lints the JavaScript files using XO and then runs the unit tests using AVA.

yarn build

Builds all of the JavaScript files using Babel.

yarn clean

Removes all untracked files (git clean -Xdf).

yarn release

Releases new version of Evergreen (requires np to be installed globally).

yarn create-package

This command scaffolds a package with no specific boilerplate. It's useful for creating utilities.

For the following command:

yarn create-package utils

The following file tree will be generated:

/src/utils
β”œβ”€β”€ /src/
└── index.js

yarn create-package:components

This command scaffolds a package with React component(s) boilerplate. You can pass one or more components to this command.

For the following command:

yarn create-package:components typography Text Heading

The following file tree will be generated:

/src/typography
β”œβ”€β”€ /src/
|   │── Text.js
|   └── Heading.js
β”œβ”€β”€ /stories/
β”‚   └── index.stories.js
└── index.js

yarn run create-docs-template

For the following command:

$ yarn run create-docs-template layers Pane Card

The following file tree will be generated:

/src/layers/docs
β”œβ”€β”€ index.js
└── /examples/
    β”œβ”€β”€ Pane-basic.example
    └── Card-basic.example

Manual steps for docs

This yarn run create-docs-template script is far from perfect and still requires manual steps. This includes:

  • Making sure to use the right examples and write some docs.
  • Configure docs/utils/getComponent.js
  • Configure docs/components/ComponentsSidebar.js
