- Multithreading is a TypeScript library for robust concurrency in JavaScript, inspired by Rust.
- Features include thread-pool architecture, memory safety, and synchronization primitives like Mutexes and Condition Variables.
- Simplifies WebWorkers, serialization, and SharedArrayBuffer complexities.
- Managed Worker Pool automates thread management based on hardware concurrency.
- Shared Memory Primitives enable safe state sharing between threads.
- Scoped Imports allow importing modules directly within worker tasks.
- Move Semantics facilitate explicit data ownership transfer to avoid cloning overhead.
- The spawn function is the primary entry point for running tasks in background threads.
- Data transfer between threads is handled via the move function, distinguishing between transferable and non-transferable objects.
- SharedJsonBuffer provides Mutex-protected shared memory for JSON objects, optimizing performance.
- Synchronization primitives include Mutex, RwLock, Semaphore, and Condvar for various concurrency needs.
- Channels offer a high-level communication mechanism for complex workflows between workers.
- Dynamic imports within spawned functions are supported, including external libraries and relative files.
- The library includes utility functions like drop for manual resource management and supports explicit resource management with the using keyword.
- Advanced features include a custom serialization protocol and import patching for correct path resolution in workers.
