Deno currently offers partial support for WASI through the wasicap_snapshot_preview1 interface. While this allows running some WASI modules, it lacks compatibility with the latest and evolving WASI 0.2 standard. Implementing full WASI 0.2 support would significantly enhance Deno's capabilities and unlock exciting possibilities for WebAssembly development and deployment.
Benefits for Deno Users:
Broader Module Compatibility: Run a wider range of WASI modules designed for modern environments, opening doors to more functionalities and libraries.
Enhanced Security: Leverage stricter security boundaries and capabilities in WASI 0.2 for more secure WASM execution within Deno.
Cutting-Edge Development: Position Deno at the forefront of WebAssembly development, attracting developers and fostering a robust WASI ecosystem.
Production-Ready Features: Enable the execution of WASI modules in server-side and cloud environments that increasingly rely on WASI for secure and performant sandboxes.
Production Use Cases:
Serverless Functions: Create secure and performant serverless functions with Deno and WASI 0.2, leveraging the benefits of both WebAssembly and Deno's runtime.
Edge Computing: Deploy WASI modules on edge devices for efficient and secure computations, facilitated by Deno's integration with WASI 0.2.
Sandboxed Microservices: Utilize WASI's secure sandbox for running untrusted code, making Deno with WASI 0.2 ideal for building microservices that require secure isolation.
Call to Action:
Implementing WASI 0.2 support now will:
Significantly enhance Deno's capabilities for running WebAssembly modules.
Improve security for WASM execution within Deno.
Position Deno as a leading platform for WASI development and deployment in various production use cases.
We strongly encourage the Deno team to prioritize the implementation of WASI 0.2 support and unlock its potential benefits for the Deno community.
