Nacl-web-plug-in

To create a post or send a message from a Native Client (NaCl) web plug-in to your web application's JavaScript, you use the PostMessage() function within your C/C++ code. 1. Send from NaCl (C/C++) In your NaCl module, you must use the PPB_Messaging interface to send data back to the browser. // Example: Sending a string from the C++ module pp::Var message( "Hello from NaCl!" ); PostMessage(message); Use code with caution.

1. Adoption of WebAssembly (Wasm): Wasm provided a lighter-weight, standards-track bytecode format that didn't require a proprietary plugin or OS-specific validators.
2. Security Maintenance: Maintaining the inner sandbox and validator for x86, ARM, and 64-bit variations became a massive engineering burden.
3. Mobile Incompatibility: NaCl never worked on iOS, and Android support was limited and buggy.
4. Plugin-Free Web: The entire web moved toward plugin-less execution; PPAPI itself was deprecated in favor of standard web APIs.
