shadcn-custom-theme v0.1.4

shadcn-custom-theme

This tool generate a custom theme similar to the ones created by the shadcn/ui Themes website.

You can specify the primary, secondary, accent, and gray colors. The color name should be one of the default Tailwind color names (e.g. red, green, blue, indigo, etc.) The primary color is required, the rest defaults to Tailwind gray.

Usage

npx shadcn-custom-theme primary=COLOR [secondary=COLOR] [accent=COLOR] [gray=color] [template=TEMPLATE.json]

This will output the CSS variables that you can paste into your global.css.

You can also specify a TEMPLATE.json file which has the default colors. See below for example.

For example

npx shadcn-custom-theme primary=orange secondary=green accent=pink gray=neutral

Will output the following:

@layer base {
  :root {
    --background: 0 0% 100% /* white */;
    --foreground: 0 0% 4% /* neutral-950 */;
    --card: 0 0% 100% /* white */;

TEMPLATE.json

This has the colors/tints for each CSS variable.

NOTE: colors prefixed with primary, secondary, accent, and gray will be replaced with the color value specified as CLI arguments. All other colors will be used directly, like red-500.

The following is the default theme template. You can override this by specifying the template=TEMPLATE.json file.
