JSS Default Theme

Inspired by Material Design & React MUI theming.

Independent part of jss-theme package.

Demo & docs

Demo and docs could be found here.

Example in sandbox could be found here.

Notes

Include necessary typescript typings.

Usage

import { createDefaultJssTheme } from 'jss-theme-default';

const theme = createDefaultJssTheme({ spacing: 12 });

console.log(theme.spacing === 12);

Desription

Default theme provides object for usage w/ JSS like stlyes approach.

It also provides bunch of methods for updating this theme or creating new one with similar structure:

Similar structure is here.

• createDefaultJssTheme(themeConfig?, ThemeInstance?) => DefaultTheme Creates structure for DefaultTheme, with optional overrides. Second param is for existing ThemeInstance in order to bind mixins to it.
• createTypography(typography?), createPalette(palette?), createBreakpoints(breakpoints?), createZIndex(zIndex?), createMixins(Theme) - aliases for creating DefaultTheme parts. Could be used for example for updating DefaultTheme theme. For each method it is possible to provide partial overrides, for all not overridden values will be used defaults.
• IMPORTANT: createPalette(palette?): for main colors (primary, secondary, error, info, success, warning) it is OK to provide only main shade. Functions will automatically calculate light, dark and contrastText color. Still you can provide custom for all of them.
• createColor(color, contrastText?, bw?) - For provided color creates color palette w/ lighten, darken, contrastText colors.
• createGreyPalette(initial?) - Creates shades of grey for provided first shade.
• createTypographyItem(fontFamily, fontWeight, fontSize, lineHeight) - Creates typography item object.
• createShadows() - Creates shadows

const shadows = createShadows(
	[1, 1, 1, 1, '#000', true],
	{ x: 5, y: 5, blur: 5, spread: 5, color: '#000', inset: true },
);// => inset 1px 1px 1px 1px #000, inset 5px 5px 5px 5px #000

• createMaterialShadows(...ps) - Similar just using some Material Design style for creating shadows. Here each 4 values represents 1 shadow:

const shadows = createMaterialShadows(0, 2, 1, -1, 0, 1, 1, 0, 0, 1, 3, 0);

• fade(color, opacity), darken(color, lvl?), lighten(color, lvl?), getContrastColor(color, bw?, black?, white?) Work w/ colors: transparency, getting dark / light shade, getting contrast text. If provided just 1 param to getContrastColor - it will invert color. If provide second boolean param -> it will get contrast (black/white color, where 3d and 4th params can override default colors for contrast black and white)
