Install guide

  1. Drag the straple library into your project folder
    a. If you are using a custom webpack/babel config (e.g. not using create-react-app), please ensure the style-loader and css-loader are installed/configured within webpack
  2. Run the command npm install ./straple inside your project folder
    a. If using yarn, use the command yarn add link:straple. This is the recommended way of installing via yarn as it allows editing variables within the local straple folder (by creating a symlink).
  3. b. Whilst the normal yarn add ./straple command can be used, this copies the library into node_modules and variables must be edited within the node_modules folder which may not be saved by version control.
  4. Straple is installed and can be accessed like any other library.
  5. For example: import { Base } from 'straple' will import a Base component.


Changing Variables (e.g. font size, colors, etc)

Editing variables.js (recommended)

Within the Straple library folder, a file named variables.js exists containing all the variables used throughout Straple (and the UI Kit). Changing any of these values will alter all the components. Note: if using Yarn, read the Yarn install notes - using the typical yarn add command may result in this method not working.

Using a ThemeProvider

A theme provider can also be used. This can be useful if you only want different variables to affect a certain part of the application.

  1. Import ThemeProvider from Straple
  2. Wrap any components you want to have in this theme
    example: <ThemeProvider><Base>I'm themed</Base></ThemeProvider>
  3. The ThemeProvider takes a prop theme which is an object containing all the variables.
  4. All variables must be defined. The easiest/best way to do this is create a copy of Variables and alter any objects needed. In the example provided below the font size for a medium Base element has been changed in the theme. The Base element wrapped within the ThemeProvider has a font size of 50px whereas the other Base element has the default font size even though they are using the 'same size' of medium - this is due to theming. The same can be done with every other variable.
Example of ThemeProvider
import { ThemeProvider, Variables, Base } from "straple"; function App() { const THEME = { ...Variables } THEME.base_medium = '50px' return ( <div> <ThemeProvider theme={THEME}> <Base size='medium'>I have a different theme</Base> </ThemeProvider> <Base size='medium'>I have the default theme</Base> </div> ) }

enum/string (or enum/other data type)

This means that there are predefined options, but ALSO a custom option can be passed.

For example for padding which is enum/string, padding can be 'small', 'regular', 'large' or any custom value such as '10px', '10px 15px', '10px 12px 14px 10px', like regular CSS.


All components support a className prop which provides a class to the top element of that component. This allows you to use Straple components within a library such as styled-components and target children elements, allowing full customisation.

extra prop

All components support an extra prop which allows you to supply more CSS to a particular component.

For example:

<Base size='medium'>base</Base>

Would be a regular Base component.

However the following component (with the extra prop):

<Base size='medium' extra='text-decoration: underline;'> base</Base>

Would have the CSS 'text-decoration: underline;' and so be rendered underlined.
