Tremor lets you create simple and modular components to build insightful dashboards in a breeze. Fully open-source, made by data scientists and software engineers with a sweet spot for design.

Getting Started

You can use tremor either within a React or Next.js Project. For new projects, we recommend using Next.js, as it also provides a simple deployment workflow through the Vercel platform. For other Frameworks, see our Installation Guide.

Using NextJS

In your terminal, we create a new Next project:

npx create-next-app my-project --typescript 
cd my-project

Install tremor from your command line via npm.

npm install @tremor/react

Install Tailwind CSS and its peer dependencies

npm install -D tailwindcss postcss autoprefixer 
npx tailwindcss init -p

Add the paths to all of your template files in your tailwind.config.js file.

/** @type {import('tailwindcss').Config} */

module.exports = {
    content: [
    "./app/**/*.{js,ts,jsx,tsx}",
    "./pages/**/*.{js,ts,jsx,tsx}",
    "./components/**/*.{js,ts,jsx,tsx}",
+   './node_modules/@tremor/**/*.{js,ts,jsx,tsx}',
    
    // Or if using src directory:
    "./src/**/*.{js,ts,jsx,tsx}",
    ],
    theme: {
    extend: {},
    },
    plugins: [],
}

Add the @tailwind directives for each Tailwind's layers to your globals.css file.

@tailwind base;
@tailwind components;
@tailwind utilities;

Start the dev server

npm run dev

⚠️ Note: Since we have not fully migrated to Next.js 13 yet, if you are using the app directory introduced in Next.js 13, wrap your tremor components in another component by using the "use client" directive. More infos on the directive and the usage of third-party libraries in Next.js 13 can be found in the Next.js docs.

If you get the following error while using the app directory: TypeError: Super expression must either be null or a function, then add the serverComponentsExternalPackages to your next.config.js.

const nextConfig = {
  experimental: {
    appDir: true,
+    serverComponentsExternalPackages: ['@tremor/react'],
  },
}

💡 Hint: Since we are in beta, please be aware that there might be breaking changes in the future.

Example

With tremor creating an analytical interface is easy.

//Card.tsx
import { Card, Text, Metric, Flex, ProgressBar } from "@tremor/react";
export default () => (
  <Card className="max-w-sm">
    <Text>Sales</Text>
    <Metric>$ 71,465</Metric>
    <Flex className='mt-4'>
        <Text>32% of annual target</Text>
        <Text>$ 225,000</Text>
    </Flex>
    <ProgressBar percentageValue={ 32 } className="mt-2" />
  </Card>
);
