GFW components
A React component library for the Global Forest Watch project built with Emotion CSS in JS styled components. All features have support for Server Side Rendering (SSR), the latest two versions of evergreen browsers and IE>=11. All designs for these components are based on the Global Forest Watch UI kit.
Installation
The library can be installed in two ways:
1. As a module
Install the package
npm install @worldresources/gfw-components
or with yarn
yarn add @worldresources/gfw-components
import and add the global styles component to the root of your app
import React from 'react'
import { GlobalStyles } from '@worldresources/gfw-components'
export const App = () => (
<>
<GlobalStyles />
<Main />
</>
)
add the font to your html document
<link
href="https://fonts.googleapis.com/css2?family=Fira+Sans:ital,wght@0,300;0,400;0,500;0,600;1,300;1,400;1,500;1,600&display=swap"
rel="stylesheet"
/>
then import components and add them to your layout
import React from 'react'
import { Header, Footer } from '@worldresources/gfw-components'
export const MyPage = () => (
<div className='l-page'>
<Header />
<div className='content'>
<h1>My page</h1>
</div>
<Footer />
</div>
)
Requirements
If you are using @worldresources/gfw-components
as a npm module there are some external requirments:
react >= 16.8
react-dom >= 16.8
2. As a static script
The static build serves as a minimum requirement for the library providing only the global styles, header, footer, and contact us modal such that is can be injected into your site without the need for a react application. The bundle is passed through the same webpack production
environment build to optimize for performance and minimization.
Add the following script tag and font to the head of your app.
<script
type="text/javascript"
src="https://gfw-assets.s3.amazonaws.com/static/gfw-assets.latest.js"
preconnect
></script>
<link
href="https://fonts.googleapis.com/css2?family=Fira+Sans:ital,wght@0,300;0,400;0,500;0,600;1,300;1,400;1,500;1,600&display=swap"
rel="stylesheet"
/>
And then place inside the html docment tags with the following ids:
<div id="headerGfw"></div>
<div id="footerGfw"></div>
<div id="contactGfw"></div>
You can pass props to the <Header />
using the window
window.gfwHeader = {
languages,
afterLangSelect,
customLogo
}
Development
Once you have cloned the repo, install the dependancies and start the styleguide.
yarn && yarn start
If you need to develop with the component library directly inside your app, you can use Yalc in lieu of yarn link
.
To do so you need to:
- Install yalc locally:
yarn global add yalc
or
npm install -g yalc
-
Work on the component updates inside this library.
-
compile locally
yarn compile
- publish in Yalc's local store
yalc publish
- inside your app where you are using this library as a dependency, first remove the dependency and then add it with yalc:
yarn remove @worldresources/gfw-components
yalc add @worldresources/gfw-components
yarn install
-
now you can run your app using the local component.
-
you can keep updating the component's code and just use:
yarn compile
yalc push
and only re run your app to see the updates in the component.
Deployment
To deploy a new version of the library follow these steps:
- Semver from master locally and follow the bash intructions for documenting the release.
release [major|minor|patch]
- Deploy the new released version to Github pages (styleguide) and to AWS bucket (static scripts).
yarn deploy
- Deploy the new released version to NPM.
npm publish
NOTE: for AWS you will need to have the creds present in your .env
file.
i18n
The <Header />
comes with a default language dropdown component with built in support for Transifex or your choice of translation method. To use the default language selector make sure you add the Transifex Live snippets to the head of your site. If you are using the static script you must add the Transifex script to translate your site.
