• Installed and available on your PATH
  
• Familiarity with the Go module system (go mod init, go mod tidy)
  

WebAssembly

• Go’s GOOS=js GOARCH=wasm target must compile successfully

• Chrome
  
• Firefox
  
• Safari
  
• Edge
  

System Tools

• git for version control and fetching dependencies
