Opinionated testing utilities for Vitest configuration, environment loading, Prisma test databases, factories, and HTTP helpers.
Type-safe RPC server for handling remote procedure calls. Provides automatic validation, error handling, execution context tracking, and Sentry integration.
Memoization decorator that caches function results based on arguments. Returns cached results for subsequent calls with the same arguments.
Type-safe environment variable validation. Ensure required environment variables exist and have proper types at application startup.
Generate consistent, unique shadow IDs based on input data. Combines SHA256 hashing, base62 encoding, and timestamp extraction for deterministic ID generation.
Base62 encoding and decoding utility for converting strings and byte arrays into URL-safe, compact representations. Useful for shortening IDs, creating readable tokens, or encoding binary data.
Type-safe RPC client for making remote procedure calls. Provides automatic serialization, error handling, and request memoization.
Generate random integers within a specified range. Simple wrapper around Math.random() with inclusive bounds.
String case conversion utilities supporting multiple formats. Convert between camelCase, PascalCase, snake_case, kebab-case, and more.
Shared OpenTelemetry bootstrap and execution-context trace fallback helpers.
Type-safe event emitter with strong typing. Define your event types upfront and get full TypeScript support for event names and payloads.
Reliable job queue built on BullMQ and Redis. Add jobs to a persistent queue and process them with automatic retries, concurrency control, and graceful shutdown.
Generate URL-friendly slugs with collision detection. Automatically handles uniqueness and provides short ID generation with random padding.
Track and manage execution context for requests, scheduled jobs, and background tasks. Provides type-safe context objects for different execution environments with support for parent-child relationships.
Route multiplexer for API endpoints. Dispatches requests to different services based on domain, path, and HTTP method with support for fallback handlers.
Type-safe error handling with structured error objects. Create consistent error responses with status codes, error codes, messages, hints, and descriptions.
Comprehensive validation framework with composable validators and modifiers. Define schemas with full TypeScript support and get detailed error messages.
Remove duplicate values from arrays using Set-based deduplication. Preserves the first occurrence of each unique value.
Lightweight wrapper for managing Sentry instances across your application. Provides a global reference that can be configured and accessed throughout your codebase.
Generate various types of unique IDs with prefixes. Supports sorted IDs with timestamps, unsorted random IDs, key IDs with checksums, and Snowflake-style distributed IDs.
Get geolocation information for IP addresses. Retrieves country, city, timezone, coordinates, ASN, and organization data from the geojs.io API.
Distributed locking using Redlock for Redis. Ensures atomic operations across multiple instances with automatic lock extension and retry logic.
Ensure a function is called only once, returning the cached result on subsequent calls. Useful for initialization functions or expensive operations that should run exactly once.
Encryption utility for securely encrypting and decrypting secrets using entity-specific passwords. Uses SHA-512 for key derivation and provides a simple API for secret management.
