Agenda

DEMO: Go component testing with Roman

  • Roman has been working on a Wasm test framework - firstly in Go as that’s where our focus is right now. PoC link for your delectation.
  • We’re calling this west. The main feature is this lets us compile our components and test against a WASI platform harness that supports the functionality we’re testing.
  • What this means is we can use pure developer tools out of the box, nothing unusual required here.
  • In this demonstration Roman shows what this testing program looks like and how it works.
  • Grabs all the Go files in my imports and replace all Wasm imports with those provided by wasmtime.
  • Debugs as a normal native application.
  • Essentially, this constructs an HTTP request then call the export handler and make assumptions based on how the component responds. This has been difficult to do until now.
  • Makes it possible to have full coverage on production functionality at runtime.
  • As always, it’s really difficult to express the goodness of the demo so please check out the recording below.
  • Also, check out the wider community discussion in the playback.
  • CTA: We’ll have WASI functionality to add to custom interfaces next week and so stay tuned for that.

DEMO: Component SDK for Go - update with Lucas

  • We can use this if we want to use a standard wasm component in Go. This is the workflow that we would use.
  • Go-native, essentially an idiomatic way to build Go-native WebAssembly components.
  • The one we currently have in wasmCloud generates Go and C files - that’s pretty much how wit-bindgen works today.
  • If we look at components that use wit-bindgen Go, you’ll see a diff set of files that wil be 100% Go - C doesn’t get a look in.
  • We are now using a different bindgen that is hosted in ByteCode Alliance tools.
  • How will this change things?
  • If we take a look at the interface names, there’s a lot of text - code that is hard to read.
  • When we look at the new generator, things become more ‘Go-like’ when interacting with any WASI object, we no longer have the package names - it points to the correct Go package and the actual names - package stream, input stream etc.
  • This is a much more streamlined way of working!
  • This means streaming is now possible in Go with this component SDK - and you can run it with any runtime that is wasi:http compliant.
  • Check out the examples that Lucas mentions here.
  • This is a great demo which we can’t do justice in notes, catch up with the demo and the wider discussion in the recording below.

DEMO: wasmCloud roadmap progress

  • Steady progress in the Q3 roadmap.
  • Making good progress - we want to thank everyone in the community for taking on these issues - super grateful to the entire community for driving significant progress. You rock!
  • Tons of progress on: sharing components and providers, sharing resources, consolidating wasmCloud Helm chart and much, much more!
  • Please take a look at the roadmap to identify all the good first issues ready for contribution - we’re excited for more of you to get involved.
  • Check out the recording for the wider discussion on progress and what comes next.

REMINDER: wasmCloud Innovation Day - 1 week to go!

  • We are super excited that wasmCloud Innovation Day is just a week away.
  • If you haven’t registered yet, you can do so here.
  • We’ll have talks on how wasmCloud is being used in industry (Akamai, Adove, MachineMetrics), a discussion with Wasm industry leaders Pat Hickey (Fastly), Yosh Wuyts (Microsoft), and a host of technical demos from your friendly, neighbourhood wasmCloud maintainers.
  • Please note the wasmCloud community meeting will take place at 10am ET next week and on a different link - we’ll publish the updated link and diary entry shortly!
