Getting Started

Vite

Everything you need to set up Tremor with Vite.

Installation

Tremor is designed for React and requires React v18.2.0+

  1. 1

    Create a new Vite project:

    In our terminal, we create a new Vite project.
    npm create vite@latest my-project -- --template react-ts && cd my-project
  2. 2

    Install Tailwind CSS v3.4.0+ and its peer dependencies

    npm install -D tailwindcss postcss autoprefixernpx tailwindcss init -p
    Repalce all content of your ./src/index.css with the @tailwind directives. We also recommend to delete everything in the App.css file.
    @tailwind base;@tailwind components;@tailwind utilities;
  3. 3

    Install @tailwindcss/forms

    To install, run:

    npm install -D @tailwindcss/forms
  4. 4

    Update tailwind.config.js

    In order for the animations to be applied correctly, we extend the tailwind.config.js. We also add the @tailwindcss/forms. Note that we also added the paths to the template files in the content section.

    /* eslint-disable no-undef *//** @type {import('tailwindcss').Config} */// (Optional) Import default theme when using a custom font (Step 7)//import defaultTheme from 'tailwindcss/defaultTheme';export default {  content: ["./index.html", "./src/**/*.{js,ts,jsx,tsx}"],  theme: {    extend: {      keyframes: {        hide: {          from: { opacity: "1" },          to: { opacity: "0" },        },        slideDownAndFade: {          from: { opacity: "0", transform: "translateY(-6px)" },          to: { opacity: "1", transform: "translateY(0)" },        },        slideLeftAndFade: {          from: { opacity: "0", transform: "translateX(6px)" },          to: { opacity: "1", transform: "translateX(0)" },        },        slideUpAndFade: {          from: { opacity: "0", transform: "translateY(6px)" },          to: { opacity: "1", transform: "translateY(0)" },        },        slideRightAndFade: {          from: { opacity: "0", transform: "translateX(-6px)" },          to: { opacity: "1", transform: "translateX(0)" },        },        accordionOpen: {          from: { height: "0px" },          to: { height: "var(--radix-accordion-content-height)" },        },        accordionClose: {          from: {            height: "var(--radix-accordion-content-height)",          },          to: { height: "0px" },        },        dialogOverlayShow: {          from: { opacity: "0" },          to: { opacity: "1" },        },        dialogContentShow: {          from: {            opacity: "0",            transform: "translate(-50%, -45%) scale(0.95)",          },          to: { opacity: "1", transform: "translate(-50%, -50%) scale(1)" },        },      },      animation: {        hide: "hide 150ms cubic-bezier(0.16, 1, 0.3, 1)",        slideDownAndFade:          "slideDownAndFade 150ms cubic-bezier(0.16, 1, 0.3, 1)",        slideLeftAndFade:          "slideLeftAndFade 150ms cubic-bezier(0.16, 1, 0.3, 1)",        slideUpAndFade: "slideUpAndFade 150ms cubic-bezier(0.16, 1, 0.3, 1)",        slideRightAndFade:          "slideRightAndFade 150ms cubic-bezier(0.16, 1, 0.3, 1)",        // Accordion        accordionOpen: "accordionOpen 150ms cubic-bezier(0.87, 0, 0.13, 1)",        accordionClose: "accordionClose 150ms cubic-bezier(0.87, 0, 0.13, 1)",        // Dialog        dialogOverlayShow:          "dialogOverlayShow 150ms cubic-bezier(0.16, 1, 0.3, 1)",        dialogContentShow:          "dialogContentShow 150ms cubic-bezier(0.16, 1, 0.3, 1)",      },    },  },  plugins: [require("@tailwindcss/forms")],}
  5. 5

    Install dependencies:

    To install, run:

    npm install tailwind-variants clsx tailwind-merge @remixicon/react

    (Optional) If you plan to use all components, you can add all dependencies here:

    npm install @radix-ui/react-accordion @radix-ui/react-checkbox @radix-ui/react-dialog @radix-ui/react-hover-card @radix-ui/react-label @radix-ui/react-popover @radix-ui/react-radio-group @radix-ui/react-select @radix-ui/react-slot @radix-ui/react-switch @radix-ui/react-tabs @radix-ui/react-toast @radix-ui/react-tooltip @radix-ui/react-navigation-menu date-fns react-day-picker @internationalized/date @react-stately/datepicker @react-aria/datepicker recharts
  6. 6

    Add font and dark mode background:

    In all our examples, we use Geist Font. This is not required, use any other font you like.

    Download the latest Geist.zip here.

    Create a new fonts folder in your assets directory. Add the variable font file from the downloaded folder.

    .├── src│   └── assets│   │   └── fonts│   │   │   └── GeistVariableVF.woff2...

    Then in the index.css, add the font face:

    @tailwind base;@tailwind components;@tailwind utilities;
    @font-face {  font-family: 'Geist Sans';  src: url('src/assets/fonts/GeistVariableVF.woff2') format('woff2');  font-style: normal;  font-weight: 100 900;}

    Next, update your tailwind.conifg.js. Make sure that you are importing the default theme.

    /* eslint-disable no-undef *//** @type {import('tailwindcss').Config} */// (Optional) Import default theme when using a custom font (Step 7)import defaultTheme from 'tailwindcss/defaultTheme';export default {  content: [    "./index.html",    "./src/**/*.{js,ts,jsx,tsx}",  ],  theme: {    extend: {    fontFamily: {      sans: ['Geist Sans', ...defaultTheme.fontFamily.sans],    },    keyframes: {//...

    To top if off, we recommend adding antialiasing and a default darkmode background to your index.html

    <html lang="en" class="antialiased dark:bg-gray-950">
  7. 7

    Add utilities and helpers

    Our components depend on a few utilities. You can read more about them in the Utilities section.

    Create a new lib folder in /src. Add a new utils.ts file inside. Paste the following utilities into this file.

    // Tremor Raw cx [v0.0.0]
    import clsx, { type ClassValue } from "clsx"import { twMerge } from "tailwind-merge"
    export function cx(...args: ClassValue[]) {  return twMerge(clsx(...args))}
    // Tremor Raw focusInput [v0.0.1]
    export const focusInput = [  // base  "focus:ring-2",  // ring color  "focus:ring-blue-200 focus:dark:ring-blue-700/30",  // border color  "focus:border-blue-500 focus:dark:border-blue-700",]
    // Tremor Raw focusRing [v0.0.1]
    export const focusRing = [  // base  "outline outline-offset-2 outline-0 focus-visible:outline-2",  // outline color  "outline-blue-500 dark:outline-blue-500",]
    // Tremor Raw hasErrorInput [v0.0.1]
    export const hasErrorInput = [  // base  "ring-2",  // border color  "border-red-500 dark:border-red-700",  // ring color  "ring-red-200 dark:ring-red-700/30",]

    Next, we add the chart utilities. Add a new chartUtils.ts file and paste the following code into this file.

    // Tremor Raw chartColors [v0.0.0]
    export type ColorUtility = "bg" | "stroke" | "fill" | "text"
    export const chartColors = {  blue: {    bg: "bg-blue-500",    stroke: "stroke-blue-500",    fill: "fill-blue-500",    text: "text-blue-500",  },  emerald: {    bg: "bg-emerald-500",    stroke: "stroke-emerald-500",    fill: "fill-emerald-500",    text: "text-emerald-500",  },  violet: {    bg: "bg-violet-500",    stroke: "stroke-violet-500",    fill: "fill-violet-500",    text: "text-violet-500",  },  amber: {    bg: "bg-amber-500",    stroke: "stroke-amber-500",    fill: "fill-amber-500",    text: "text-amber-500",  },  gray: {    bg: "bg-gray-500",    stroke: "stroke-gray-500",    fill: "fill-gray-500",    text: "text-gray-500",  },  cyan: {    bg: "bg-cyan-500",    stroke: "stroke-cyan-500",    fill: "fill-cyan-500",    text: "text-cyan-500",  },  pink: {    bg: "bg-pink-500",    stroke: "stroke-pink-500",    fill: "fill-pink-500",    text: "text-pink-500",  },} as const satisfies {  [color: string]: {    [key in ColorUtility]: string  }}
    export type AvailableChartColorsKeys = keyof typeof chartColors
    export const AvailableChartColors: AvailableChartColorsKeys[] = Object.keys(  chartColors,) as Array<AvailableChartColorsKeys>
    export const constructCategoryColors = (  categories: string[],  colors: AvailableChartColorsKeys[],): Map<string, AvailableChartColorsKeys> => {  const categoryColors = new Map<string, AvailableChartColorsKeys>()  categories.forEach((category, index) => {    categoryColors.set(category, colors[index % colors.length])  })  return categoryColors}
    export const getColorClassName = (  color: AvailableChartColorsKeys,  type: ColorUtility,): string => {  const fallbackColor = {    bg: "bg-gray-500",    stroke: "stroke-gray-500",    fill: "fill-gray-500",    text: "text-gray-500",  }  return chartColors[color]?.[type] ?? fallbackColor[type]}
    // Tremor Raw getYAxisDomain [v0.0.0]
    export const getYAxisDomain = (  autoMinValue: boolean,  minValue: number | undefined,  maxValue: number | undefined,) => {  const minDomain = autoMinValue ? "auto" : minValue ?? 0  const maxDomain = maxValue ?? "auto"  return [minDomain, maxDomain]}
    // Tremor Raw hasOnlyOneValueForKey [v0.1.0]
    export function hasOnlyOneValueForKey(  array: any[],  keyToCheck: string,): boolean {  const val: any[] = []
      for (const obj of array) {    if (Object.prototype.hasOwnProperty.call(obj, keyToCheck)) {      val.push(obj[keyToCheck])      if (val.length > 1) {        return false      }    }  }
      return true}

    Notes on your project structure

    When adding components, we recommend adding them to a components directory inside /src. Here is an example on how we'd structure our app:

    .├── src│   ├── components│   │   ├── Accordion.tsx│   │   ├── Badge.tsx│   │   └── ...│   ├── lib│   │   └── utils.ts│   ├── App.css│   ├── App.tsx│   ├── index.css│   ├── main.tsx│   └── ...├── package-lock.json├── package.json├── postcss.config.js├── tailwind.config.js├── tsconfig.node.json└── vite.config.ts

Dark mode usage:

For all examples, we use bg-gray-950 as the overall background color. You can add this to your <html class="dark:bg-gray-950"> tag.

Font smoothing (antialiasing):

On our website, we apply font smoothing and recommend you do the same. Simply add the antialiased utility to the HTML tag <html className="antialiased">.
