Settings

Sometimes you want to override the default settings for the layout, such as media queries. React Crisscross ships with a module that can help you inject custom settings.

Layout Provider

import Layout, { LayoutProvider } from '@ludens-reklame/react-crisscross';

const mySettings = {
  mediaQueries: {
    lg: 1500
  }
}

<LayoutProvider settings={mySettings}>
  <Layout container>
    <Layout item>
      {/* Content */}
    </Layout>
  </Layout>
</LayoutProvider>

Default settings

These settings can be overwritten by the LayoutProvider.

const settings = {
  mediaQueries: {
    xs: 0,
    sm: 600,
    md: 960,
    lg: 1280,
    xl: 1920
  },
  columns: 12
};

Development

Although all instructions for development in React Crisscross use yarn as package manager, npm can also be used.

Install

$ git clone [e-mail]:ludens-reklamebyra/react-crisscross.git

yarn storybook

Unit tests

React crisscross is tested with snapshots using Jest. Run the test suite using the command:

yarn test

To run test suite in watch mode use:

Snapshots

When you have to do breaking changes to React crisscross, the snapshots needs to be updated, or else they will fail the tests. You can do this by running the command:

yarn test:update-snapshots
