WASI Capabilities & Future
Explore the current capabilities of WASI, its security model, and its potential impact on server-side and edge computing.
WASI Capabilities: Overview
Welcome to our lesson on WASI's capabilities and its future! We'll explore what WebAssembly System Interface (WASI) enables, how it ensures security, and its impact on server-side and edge computing.
WASI aims to standardize how WebAssembly modules interact with the operating system, allowing them to run outside the browser in a portable and secure way.
Core WASI Capabilities
At its heart, WASI provides a set of standardized system calls for common OS features. Think of it as a virtual OS interface for WebAssembly.
- Filesystem access: Reading, writing, and managing files and directories.
- Network sockets: Creating connections and communicating over networks.
- Time & Randomness: Accessing system time and generating secure random numbers.
- Environment variables: Reading host environment variables.
These capabilities are crucial for non-browser applications.
