[BUG] Compiling to wasm fails

[paulm17]

I'm following the article: https://permify.co/post/wasm-go/

Step 1:

GOOS=js GOARCH=wasm go build -o permify.wasm main.go

Results in:

# go.opentelemetry.io/otel/exporters/jaeger/internal/third_party/thrift/lib/go/thrift
/Users/paul/go/pkg/mod/go.opentelemetry.io/otel/exporters/[email protected]/internal/third_party/thrift/lib/go/thrift/socket_unix_conn.go:60:63: undefined: syscall.MSG_PEEK

Hello @paulm17, could you please pull the latest updates and try again? Navigate to the path pkg/development/wasm by running:

cd pkg/development/wasm

Then, execute the following command to build:

GOOS=js GOARCH=wasm go build -o permify.wasm main.go

Alternatively, you can simplify this process by using:

make wasm-build

Let me know if it works!

Running the two examples:

paul@Pauls-MBP-2 permify % make wasm-build
cd ./pkg/development/wasm && GOOS=js GOARCH=wasm go build -ldflags="-s -w" -o main.wasm && wasm-opt main.wasm --enable-bulk-memory -Oz -o play.wasm
/bin/sh: wasm-opt: command not found
make: *** [wasm-build] Error 127

paul@Pauls-MBP-2 permify % cd pkg/development/wasm
paul@Pauls-MBP-2 wasm % ls
main.go		main.wasm
paul@Pauls-MBP-2 wasm % GOOS=js GOARCH=wasm go build -o permify.wasm main.go
paul@Pauls-MBP-2 wasm % ls
main.go		main.wasm	permify.wasm

Hello, as you can see, the second one works, and for the first one, you need to install the wasm-opt package. After that it should work

Yes, I just wanted to confirm with you. Many thanks for resolving this! 👍
