State Management
Provide/Inject
import Vue from 'vue';
import Vuex from 'vuex';
Vue.use(Vuex);
const store = new Vuex.Store({
state: {
isDarkMode: isDarkMode(),
},
mutations: {
toggleDarkMode(state, darkMode) {
state.isDarkMode = darkMode;
},
},
});
<template>
<theme-provider :theme="theme">
<layout :isDarkMode="isDarkMode">
<slot/>
</layout>
</theme-provider>
</template>
<script>
import styled, { ThemeProvider } from 'vue-styled-components';
import theme from '@/plugins/theme';
import { LightLayout, DarkLayout } from './ModeLayouts';
const layoutProps = { isDarkMode: Boolean };
const Layout = styled('div', layoutProps)`
${({ isDarkMode }) => (isDarkMode ? DarkLayout : LightLayout)}
`;
export default {
components: { Layout, ThemeProvider },
data() {
return { theme }
},
computed: {
isDarkMode() { return this.$store.state.isDarkMode },
},
};
</script>
/* plugins/theme.js */
const theme = {
dark: {
background: '#2d3239',
title: '#e9d970',
text: '#fff',
subLabelText: '#cfcfcf',
},
light: {
background: '#fff',
title: '#333',
text: '#2c3e50',
subLabelText: '#757575',
},
};
Single configurations

vue-styled-component
CSS Variables for common theme
polished
communicate CSS on run-time
import styled from 'vue-styled-components';
import {
getStyledTitle
} from '@/components/PokemonItem/StyledPokemonTitle';
import {
DarkLayout,
LightLayout
} from '@/layouts/ModeLayouts';
import { lighten } from 'polished';
const itemProps = {
themeColor: String,
isDarkMode: Boolean,
};
export const InfoSection = styled('section', itemProps)`
border-left: 1px solid ${(props) => props.themeColor};
border-right: 1px solid ${(props) => props.themeColor};
background: var(--page-background);
`;
export const SectionTab = styled('h3', itemProps)`
border-bottom: 1px solid ${(props) => props.themeColor};
color: ${(props) => lighten(0.1, props.themeColor)};
`;
const StyledView = styled('div', itemProps)`
${({ isDarkMode }) => (isDarkMode ? DarkLayout : LightLayout)};
background: ${(props) => props.themeColor};
`;
<template>
<styled-view :themeColor="color" :isDarkMode="isDarkMode">
<div class="pokemon-main-view">
<section class="pokemon-view--top-section">
<!--...-->
<cld-image
type="fetch"
:public-id="pokemon.avatar"
width="220"
crop="scale"
class="pokemon-view--image"
/>
<info-section :themeColor="color">
<section-tab :themeColor="color">About</section-tab>
<tab-details>
<details-row>
<!--something-->
</details-row>
</tab-details>
</info-section>
</div>
</styled-view>
</template>
dynamic theme - extendable styles
import { css } from 'vue-styled-components';
export const LightLayout = css`
--page-background: ${(props) => props.theme.light.background};
--page-title: ${(props) => props.theme.light.title};
--page-text: ${(props) => props.theme.light.text};
--page-sub-label-text: ${(props) => props.theme.light.subLabelText};
`;
export const DarkLayout = css`
--page-background: ${(props) => props.theme.dark.background};
--page-title: ${(props) => props.theme.dark.title};
--page-text: ${(props) => props.theme.dark.text};
--page-sub-label-text: ${(props) => props.theme.dark.subLabelText};
`;
import StyledButton from './StyledButton';
const TomatoButton = StyledButton.extend`
color: tomato;
border-color: tomato;
`;
export default TomatoButton;
