1  # Deploying Rust and WebAssembly to Production

 4  > identical to deploying any other Web application!**

 6  To deploy a Web application that uses Rust-generated WebAssembly on the client,
 7  copy the built Web application's files to your production server's file system
 8  and configure your HTTP server to make them accessible.

10  ## Ensure that Your HTTP Server Uses the `application/wasm` MIME Type
11  
12  For the fastest page loads, you'll want to use [the
13  `WebAssembly.instantiateStreaming` function][instantiateStreaming] to pipeline
14  wasm compilation and instantiation with network transfer (or make sure your
15  bundler is able to use that function). However, `instantiateStreaming` requires
16  that the HTTP response has the `application/wasm` [MIME type][] set, or else it
17  will throw an error.
