How to create and use the Design System

Component composition.

• When creating components that consists of several components, each component should be styled.
• Each components that is used to create a "composed" component should be styled, and remember to check if the component alread is styled.
• When creating a "composed component" evalute if it's really needed to create a composed component, or just document how to use the styled components.
  • MUI often has documentation on how to create composed components.

Documentation and testing

• All components shall be documented and tested in Storybook before PR is created.

Changelog

The project uses "changesets" to automatically bump version and create a changelog.

For each new feature or change run "npx changeset". Choose patch for a change or bug fix, minor for a new feature or major version for a breaking change. This creates a markdown file in .changeset folder. Commit to brach/PR as normal.

A PR can have several changesets.

The pipeline will automatically bump version and create changelog after merge to master.

Index file

• Index files shall not be edited manually.
• ctix is used for automatically create index files for exporting componens. Run "npm run create-index"
• 'src/styles/index.ccss' is imported to 'src/theme/customMuiColors.ts' so exporting works with ctix.

Using MUI theme in App

import { createMuiTheme, ThemeProvider } from '@material-ui/core/styles';
import { defaultTheme, customPalettes } from 'asma-ui-notistack';

const dataTheme = window.document.body.attributes.getNamedItem('data-theme');

const getTheme = () => {
  switch (dataTheme?.value) {
    case 'fretex':
      return customPalettes.fretex.primary;
    default:
      return null;
  }
};

const theme = createTheme(defaultTheme, {
  palette: {
    ...defaultTheme.palette,
    primary: {
      ...getTheme(),
    },
    role: customPalettes.role,
  },
});

<React.Fragment>
  <ThemeProvider theme={createMuiTheme(theme)}>
    <... />
  </ThemeProvider>
</React.Fragment>

Using Components in App

import { StyledButton } from 'asma-ui-notistack';
