Oak Components

Overview

This is a React Typescript components library which supports React and Next applications produced by Oak National Academy.

Installation

This library is suitable for use in an app using React 18 and Next.js 13.5+

You can install it using npm i @oaknational/oak-components or any other package manager that supports the NPM registry.

👉 You'll need two environment variables to enable images NEXT_PUBLIC_OAK_ASSETS_HOST and NEXT_PUBLIC_OAK_ASSETS_PATH. Values for these can be obtained from the .env config from OWA or from a fellow engineer.

Theming, global styles and fonts

For components to be styled correctly they will need access to a theme, some global styles and the Lexend font.

If you're using the Next.js App router your root layout should look something like:

// layout.js
import { OakThemeProvider, oakDefaultTheme, OakGlobalStyle } from "@oaknational/oak-components";
import { Lexend } from "next/font/google";

const lexend = Lexend({ subsets: ['latin'] });

export default function RootLayout({ children }) {
  return (
    <html lang="en">
      <OakGlobalStyle />
      <body className={lexend.className}>
        <OakThemeProvider theme={oakDefaultTheme}>{children}</OakThemeProvider>
      </body>
    </html>
  );
}

To enable SSR of styles and avoid a flicker of unstyled content you'll need to configure your Next.js app to support styled-components

TypeScript

If you're using TypeScript you might want to add @types/styled-components to your development dependencies (npm i -D @types/styled-components). This will ensure that all components are properly type hinted in your IDE.

Development

Copy the example env config cp .env.example .env
Populate .env with values from the 1Password developer vault, search for: "Oak components .env"
run nvm use
run npm install
To view the storybook run npm run storybook

Making changes

We use conventional commits and semantic versioning. Releases are managed by Semantic Release and are automatically published to NPM on every merge to main.

Changes should go through a pull-request to main and require approval by at least 1 reviewer. You should seek reviews from a QA/designer/PM when necessary.

The release process is driven by the commit messages, following the Conventional Commits standard. The @semantic-release/commit-analyzer plugin will determine the type of release (major, minor, or patch) based on the commit message.

Here’s a summary of the commit types that trigger a release:

Patch release (x.x.x): Commits that start with fix: or contain other conventional keywords indicating bug fixes.
Minor release (x.x.0): Commits that start with feat: indicate a new feature but not a breaking change.
Major release (x.0.0): Commits that contain BREAKING CHANGE: in their description, which indicates a breaking change that requires a major version bump.

Commit messages that begin with chore, refactor or docs, etc. will not trigger the release process.

Testing components inside a host app like OWA

Sometimes it isn't enough to develop entirely inside Storybook and it might be necessary to try local changes inside a target app. You can do this with yalc

Install yalc npm i yalc -g
Run npm run publish:local to add the package to yalc's local registry.
Inside the target app run yalc add @oaknational/oak-components — this will install the package from the local registry like it would from NPM
- 🚨 if you're an Oak engineer developing in OWA there is a convenience script and you should use npm run use-local-components instead as it will perform some additional work to remove any existing installation of the package.
Now when you start your target app you should have access to the locally packaged version of the library
To uninstall the local package you can run yalc remove @oaknational/oak-components inside the target app
- 🚨 if you're an Oak engineer developing in OWA there is a convenience script and you should use npm run remove-local-components instead as it will automatically re-install the library from NPM.

Organisational structure

⚠️ When creating a new component and in doubt of which category or folder it should belong to, discuss in #oak-components Slack channel.

Components

generic components or components used by more than one repo
organised in the subfolders within 'Components' folder

Current shared components subfolders

Typography

All typography related components

Buttons

All buttons and icon buttons

Form elements

Form elements including form elements styled as buttons

Images and icons

Components to render icons, images or SVGs

Messaging and feedback

Components which role is to display a message or provide feedback to the user

Layout and structure

Components which are used for creating layout

Navigation

Components which main role is navigation

Presentational

Components which main function is presentational

Cookies

Cookie related layouts

Internal components

an internal component is a non exported component which supports several shared Oak Components
organised within 'Internal components' folder

Squad specific components

components built to serve a specific repo
organised within relevant squad specific folders
for new squad specific components, build them directly within a relevant repo; the current caveat is that if squad specific component imports any of the internal components which are not exported, it needs to be built within oak-components - in this case build it within squad specific folder
