WASM on Edge Serverless; Make Your Life Easier with Go and TinyGo
summary
Go 1.21+ exposes WASI support in Go 1.21+ so you can compile Go and TinyGo to Wasm, deploy a single .wasm to Fastly’s edge CDN, and run HTTP handlers, KV reads/writes, and even goroutines/channels at global scale without managing regional servers. TinyGo produces smaller binaries and in microbenchmarks is faster for short loops but slows relative to standard Go as loop counts grow; component model v0.2 enables multi-language components; build and deploy commands work and examples successfully run on Fastly’s network.
