TypeScript
AbortController-Wrapped Fetch
Wire an AbortController so you can cancel in-flight fetches when the user navigates away or types another search query. The optional timeout helper rejects automatically.

TypeScript
useFetch — Minimal Data Fetching Hook
A tiny self-contained data-fetching hook with loading/error/data states and AbortController cleanup on unmount. Good baseline before reaching for TanStack Query.
TypeScript
Bearer-Auth Fetch Wrapper
Wrap fetch so every request automatically attaches an Authorization: Bearer header from a token getter. Token can be a static string or a function (useful for refreshing).
TypeScript
URL Builder with Type-Safe Query
Build URLs with a clean query-param API. Skips null/undefined automatically, encodes everything, and accepts arrays for repeated keys. Avoids manual string concatenation.
TypeScript
Typed Fetch Wrapper
A thin fetch wrapper that returns parsed JSON typed as `T`, throws on non-2xx, and accepts an AbortSignal. Single source of truth for "how this app talks to APIs."
JavaScript
Promise All with Concurrency Limit
Runs an array of async tasks with a maximum concurrency cap, preventing you from firing hundreds of requests simultaneously. Processes items in batches, moving to the next as slots free up. Essential when hitting rate-limited APIs or processing large datasets without overwhelming the server.
JavaScript
Fetch with Retry
Wraps the native fetch API with automatic retry logic using exponential backoff. Retries on network errors or non-OK HTTP responses up to a configurable number of attempts. Exponential backoff with optional jitter prevents thundering herd problems when many clients retry simultaneously.
JavaScript
JSON Fetch Wrapper
A thin wrapper around fetch that automatically serialises the request body to JSON, sets the Content-Type header, parses the response as JSON, and throws a descriptive error on non-OK responses. Covers the boilerplate needed for 95% of REST API calls in a single reusable function.
