DynamicInterval

Lightweight scheduler for running arbitrary work on a dynamic interval. Ideal for backoff retry loops, background autosaves, and heartbeat polling. Ensures runs never overlap and supports adaptive delays, jitter, and full lifecycle controls.

Features

  • Non-overlapping runs (no reentrancy) with automatic rescheduling after each run
  • Dynamic delay calculation via strategies (exponential, linear, constant, or custom)
  • Jitter support to avoid thundering herds (none, full, or bounded ±percentage)
  • Lifecycle controls: start, pause, resume, stop, runNow, resetBackoff

Theo's preferred way of handling try/catch in TypeScript
// Types for the result object with discriminated union
type Success<T> = {
data: T;
error: null;
};
type Failure<E> = {
data: null;
error: E;
};

React Hook - Server-Sent Events (SSE)

Server-Sent Events (SSE) are commonly used in real-time applications where the server needs to push updates to the client.

Here are a few use cases:

  1. Real-time notifications: SSE can be used to push notifications to the client in real-time. For example, in a social media application, the server can push notifications about new posts, likes, comments, etc.
  2. Live news updates: In a news application, the server can push live news updates to the client.
  3. Real-time analytics: In an analytics dashboard, the server can push real-time data updates to the client.
  4. Chat applications: In a chat application, the server can push new messages to the client in real-time.
  5. Online multiplayer games: In an online multiplayer game, the server can push game state updates to the client in real-time.
  6. Stock price updates: In a stock trading application, the server can push real-time stock price updates to the client.
