spin VS spec

For example, here's a snippet of my Git config for the spin repository:

We built (and open-sourced) Spin to make the developer experience easier, and we want to show you this through Fermyon's Advent of Spin. You will be presented with fun coding challenges that'll help you learn to build with Spin and WebAssembly.

Fermyon Spin is the open source tool for building serverless functions with WebAssembly. We’re going to use a few Spin commands to go from blinking cursor to deployed app in just a few minutes. Along the way, we’ll walk through a Spin project and see some of the features of Spin 2.0.

linky: https://github.com/fermyon/spin#readme (Apache 2; and while I don't see any CLA, interestingly they do require GPG signed commits: https://developer.fermyon.com/spin/contributing-spin#committ... )

To install the binary file on Windows, download the Windows binary release, unzip the file, and place the spin.exe file in your system path.

We are delighted to introduce Spin 1.0, the first stable release of the open source developer tool for building serverless applications with WebAssembly (Wasm)! Since we first introduced Spin last year, we have been hard at work together with the community on building a frictionless developer experience for building and running serverless applications with Wasm.

“Waggy is used for writing WAGI (WebAssembly Gateway Interface) compliant API routers/individual handlers. WAGI was developed by deislabs for accepting and routing incoming HTTP requests with WebAssembly via a configuration file (modules.toml) defining routes, modules, volumes to be mounted, etc. WAGI can run as a stand alone server, or with a framework such as the Fermyon/Spin framework Go SDK. Waggy allows for the flexibility of handling the routing via the modules.toml, or to define it code (Waggy is written in Go), as well as various pieces of convenient functionality such as the new features described above!!”

They’re VC-funded and will vendor lock-in you. See their response to my discussion:

https://github.com/fermyon/spin/discussions/861

With WasmEdge there is no vendor lock-in, it’s opaque and standards-based

What language do you want? And how experimental are you wanting to go? This project is crazy cool https://github.com/fermyon/spin , but might be harder to work with if you’re not willing to use rust :p, think they might have made it easy for c# too though

OWASP also provides Coraza, a port of ModSecurity available as a Go library. Coraza Proxy Wasm is built on top of Coraza and implements the proxy-wasm ABI, which specifies a set of Wasm interfaces for proxies. Finally, Apache APISIX offers proxy-wasm integration.

APISIX supports Wasm through the WebAssembly for Proxies (proxy-wasm) specification. APISIX is a host environment that implements the specification, and developers can use the SDKs available in multiple languages to create plugins.

Hi HN!

For the past few weeks we've been working on Proximal - a workflow engine that lets you quickly iterate on WebAssembly extensions for Envoy Proxy[0] (or other proxies) right on your local machine: https://github.com/apoxy-dev/proximal

This work is based on Proxy-WASM[1] extension ABI for Envoy (and other proxies like APISIX and Mosn[2]) which allows you to execute WebAssembly code on every API request a la Cloudflare Workers. As part of our wider effort at https://apoxy.dev to improve API glue code we built an experimentation / development platform and hope you will find it useful!

On the technical side this project packs Envoy itself, Envoy controller, REST API (for controlling the controller =)), React SPA, and Temporal server/worker (for orchestration) - all baked into a single Go binary. You can find more on architecture and limitations in the repository README[4].

This project is pretty early stage and we would appreciate community feedback!

Wasm Labs dev here :)

In mod_wasm, there are some differences with a pure CGI implementation. When Apache boots, it loads the configuration and initializes the WasmVM. When a new HTTP request arrives, the VM is ready so you don't need to initialize a different process to manage it.

You still need to process the request and pass the data to the Wasm module. This step is done via STDIN through the WebAssembly System Interface (WASI) implementation [0]. The same happens in the opposite direction, as the module returns the data via STDOUT.

So, the CGI pattern is still there, but it doesn't require new processes and all the code runs in a sandbox.

However this is not the only way you can run a Wasm module. In this specific case, we use CGI via WASI. In other cases, you may compile a module to fulfill a specific API, like ProxyWasm [1] to create HTTP filters for proxies like Envoy.

The team considered to solve the issue with C++ extensions, but discarded this approach as neither APIs nor ABIs were stable. Instead, they chose to provide a stable WebAssembly-based ABI. If you're interested in a more detailed background, you can read the whole piece on GitHub.
