Rocket.jl

Welcome to Rocket.jl, a powerful reactive programming framework for Julia! 🚀

Rocket.jl brings reactive programming paradigms to Julia, making it easy to work with asynchronous data streams, event-based programming, and reactive patterns. Whether you're building interactive applications, handling real-time data, or managing complex event-driven systems, Rocket.jl provides the tools you need.

Why Rocket.jl?

🔄 Reactive Programming: Handle asynchronous data streams with ease
🛠️ Rich Operator Library: Transform, filter, and combine data streams using powerful operators
🎯 Type-Safe: Leverage Julia's type system for robust reactive applications
🚦 Flow Control: Manage complex event flows and data transformations
⚡ High Performance: Outperforms other reactive programming libraries in Julia

Quick Example

Here's a fun example that creates a bouncing ball animation using Rocket.jl:

using Rocket, Compose, IJulia

# Function to draw the ball at a given time
function draw_ball(t)
    IJulia.clear_output(true)
    x = -exp(-0.01t) + 1                      # x coordinate
    y = -abs(exp(-0.04t)*(cos(0.1t))) + 0.83  # y coordinate
    display(compose(context(), circle(x, y, 0.01)))
end

# Create an observable that emits every 20ms, limited to 200 emissions
source = interval(20) |> take(200)

# Subscribe to animate the ball
subscription = subscribe!(source, draw_ball)

# Later, you can stop the animation with:
# unsubscribe!(subscription)

This example demonstrates how Rocket.jl can be used for reactive animations. The ball's position is updated based on time, creating a smooth bouncing effect.
