Community Calls
wash OAuth Plugin & the Wasm Component Model Plugin System
The July 30, 2025 wasmCloud community call shows off the Wasm component model as a plugin system. Brooks Townsend demos an OAuth plugin for the wash CLI — a TinyGo WebAssembly component that runs a full OAuth login flow, stores credentials, and stays sandboxed in its own little file system — then lays out the migration path that takes the next-generation Wasm Shell into the wasmCloud org. Along the way the team agrees to ship the current wash as 1.0, call a feature freeze, surface a batch of good first issues, and check in on the Q3 roadmap, including the move to wRPC-based capability providers. Oh, and wasmCloud just passed 2,000 GitHub stars.
wash GitHub Actions & a Plugin System Built on Wasm Components
The July 23, 2025 wasmCloud community call is a developer-tooling deep dive built around Wasm components. Bailey Hayes walks through her exploration of GitHub Actions for the reimagined wash CLI — demoing a setup-wash-action, comparing composite, TypeScript, and Docker action styles, and digging into caching and CI supply-chain security. Brooks Townsend then shows the new wash plugin system, where every plugin is a WebAssembly component, and demonstrates how clap integration gives plugins native subcommands, flags, and environment variables. The group closes on how to trust third-party plugins by leaning on the Wasm sandbox and capability-based security.
wash: The Wasm Shell — a Plugin-Driven Wasm Component CLI
The July 16, 2025 wasmCloud community call is a ground-up rewrite of wash — "the Wasm Shell" — into a lean, plugin-driven CLI focused purely on Wasm component model development: build, run a dev loop, and push to an OCI registry, with everything wasmCloud-specific moving out into WebAssembly-component plugins. Brooks Townsend demos building and running components with no wasmcloud.toml, implementing a draft WASI interface with a component plugin, and hooking the dev loop with an Aspire dashboard plugin. The call closes with Eric Gregory's Q3 2025 roadmap recap, an issue of the week, and a new community Excalidraw room for diagrams.
wasmCloud Q3 2025 Roadmap: Component Model, wRPC & a Simpler Host
The July 9, 2025 wasmCloud community call was the Q3 2025 community roadmap planning session. Brooks Townsend recapped a Q2 driven largely by community contributors, then walked a slate of proposals that all push toward a simpler, more standards-aligned platform built on the Wasm component model: in-process component-to-component calls, dropping wasmCloud-specific signing for standards like Sigstore, shared platform-level capability providers, reframing providers as wRPC servers, trimming built-in WASI interfaces, reducing host responsibilities so an external scheduler drives the host, and making wasmCloud's distributed networking intentional rather than implicit. WASI Preview 3, expected in August, frames much of the work.
whamm: Wasm Instrumentation and the Component Model
The June 25, 2025 wasmCloud community call welcomes Elizabeth Gilbert, a Carnegie Mellon PhD student researching WebAssembly instrumentation, who demos whamm — a DTrace-inspired DSL for dynamic analysis that rewrites Wasm bytecode (or hooks an engine at runtime) to count calls, profile branches, and build flame graphs. The conversation turns to bringing whamm to the Wasm component model, then the maintainers declare "pull request bankruptcy" — a plan to unblock a backlog of high-quality PRs stuck behind flaky tests — and congratulate two new maintainers.
