styled-themer

Utility function to select a theme element from a styled components theme

Installation

npm i styled-themer

Usage

The simplest way to use styled-themer is via the default import t, which can be used to select a particular theme element as follows:

import styled from "styled-components";
import t from "styled-themer";

// Normal way
const Text1 = styled.span`
  color: ${props => props.theme.color.primary};
`;

// Using styled-themer
const Text2 = styled.span`
  color: ${t("color", "primary")};
`;

Apart from this, there are also shorthands color, bgColor and fontSize to further reduce the amount of code required.

import styled from "styled-components";
import { color, bgColor, fontSize } from "styled-themer";

// Normal way
const Wrapper = styled.div`
  color: ${props => props.theme.color.primary};
  background-color: ${props => props.theme.color.background};
  font-size: ${props => props.theme.fontSize.normal};
`;

// Using styled-themer
const Wrapper22 = styled.span`
  ${color("primary")};
  ${bgColor("background")};
  ${fontSize("normal")};
`;

color and bgColor select the given key from theme.color, and add the CSS property (color: and background-color:) as a prefix.
