!flow token demo

FlowToken is a React component library designed to enhance the visual presentation of text streaming from large language models (LLMs). This library offers a variety of animations that make the text appear smoothly and dynamically, providing an engaging user experience.

Demo

Features

FlowToken includes several key features:

- Customizable Animations: A range of animations such as fade, blur-in, drop-in, slide from the left, typewriter effect, word pull-up, flip text, gradual spacing, and more.
- Smooth Text Streaming: Options to control the speed and manner of text appearance to handle the variability in text generation speed.
- Responsive and Lightweight: Optimized for performance and compatibility across all modern browsers.

Installation

Install FlowToken using npm:

``bash
npm install flowtoken
`

Or using yarn:

`bash
yarn add flowtoken
`

Usage with Next.js 15+

When using FlowToken with Next.js 15 and Turbopack, it's recommended to import and use the injectStyles function in your layout or page component. This resolves CSS loading issues that may occur with direct CSS imports:

`jsx
import { injectStyles } from 'flowtoken';
import { useEffect } from 'react';

export default function Layout({ children }) {
// Inject the styles globally on the client side
useEffect(() => {
injectStyles();
}, []);

return

`css
/ In your global.css /
@import '~flowtoken/dist/styles.css';
`

Usage

Markdown Support

To use markdown, import the AnimatedMarkdown component.

`jsx
import React from 'react';
import { AnimatedMarkdown } from 'flowtoken';

const App = () => {
return (
content="## Hello, world!"
sep="word"
animation="fadeIn"
animationDuration="0.5s"
animationTimingFunction="ease-in-out"
/>
);
};

export default App;
`

$3

`jsx
'use client'

import { useChat } from 'ai/react'
import { AnimatedMarkdown } from 'flowtoken';

export default function Chat() {
const { messages, input, handleInputChange, handleSubmit } = useChat()

return (


You can use custom components by passing a customComponents prop to the AnimatedMarkdown component where the key is the regex pattern (ex. /\{\{.*?\}\}/) or HTML tag (ex. MyComponent) to match and the value is the component to render. Then just prompt your LLM to output the custom component syntax and it will be rendered with your custom component.

#### Example

This is an example of a custom component.

$3

- content: The text to be displayed.
- sep: word or char.
- animation: Name of the CSS animation to apply. See below for options or define your own in css.
- animationDuration: CSS Duration of the animation. Ex. 0.6s
- animationTimingFunction: CSS Timing function of the animation. Ex. ease, ease-in-out, etc
- codeStyle: The highlighter js style object to use.
- customComponents: An object where the key is the regex pattern (ex. /\{\{.*?\}\}/) or HTML tag (ex. MyComponent) to match and the value is the react component to render.
- htmlComponents: An object where the key is the HTML tag (ex. code, h1, h2, etc) to match and the value is the react component to render.

Animations

FlowToken supports various CSS animations:
- fadeIn
- blurIn
- typewriter
- slideInFromLeft
- fadeAndScale
- rotateIn
- bounceIn
- elastic
- highlight
- blurAndSharpen
- dropIn
- slideUp
- wave

For custom animations, define your keyframes in CSS and pass the animation name to the animation prop.

$3

To lower the memory footprint, disable animations by setting the animation parameter to null on any completed messages.

If using tailwind with generated markdown, be sure to setup tailwind typography: https://github.com/tailwindlabs/tailwindcss-typography

and add prose lg:prose-md prose-pre:p-0 prose-pre:m-0 prose-pre:bg-transparent to your flowtoken markdown container.

StreamText

Here is a simple example of how to use the StreamText component from FlowToken, which does not render markdown:

`jsx
import React from 'react';
import { StreamText } from 'flowtoken';

const App = () => {
return (
content="Hello, world!"
windowSize={5}
delayMultiplier={1.1}
sep="word"
animation="fadeIn"
animationDuration="0.5s"
animationTimingFunction="ease-in-out"
/>
);
};

export default App;
`

This includes the option to smooth the rate of text display in effect reducing fluctuations in token generation speed by applying a simple moving average.

$3

- content: The text to be displayed.
- windowSize: Number of tokens to consider for smoothing animations.
- delayMultiplier: Multiplier to adjust the delay for each token or character's appearance.
- sep: word or char`
- animation: Name of the CSS animation to apply.
- animationDuration: Duration of the animation.
- animationTimingFunction: Timing function of the animation.
