The Native Client module is included in the page with an tag that points to a manifest file.

Index.html: Contains the HTML layout of the page as well as the JavaScript code that interacts with the Native Client module. The stub code for the tutorial is available in the SDK, in pepper_$(VERSION)/getting_started/part1.

Keep the Developer Tools pane open while developing Native Client applications.

Under the “General” settings, check the box next to “Disable cache (while DevTools is open)”.

Click the gear icon in the bottom right corner of the Chrome window.

Open Chrome’s developer tools by clicking the menu icon and choosing Tools > Developer tools.

Chrome caches resources aggressively disabling the cache helps make sure that the latest version of the Native Client module is loaded during development. To find out the version of Chrome, type about:chrome in the address bar.įor a better development experience, it’s also recommended to disable the Chrome cache. Older PNaCl modules will always work with newer versions of Chrome, but the converse is not true. We recommend that you use a version of Chrome that’s the same or newer than the SDK bundle used to build Native Client modules. The one provided with the SDK is just a convenience, not a requirement. If no port number is specified, the server defaults to port 5103, and can be accessed at Any server can be used for the purpose of development.

See Download the Native Client SDK for more details. If you don’t know which version you need, use the one labeled (stable) by the naclsdk list command. In the sample invocation above pepper_$(VERSION) refers to the specific version you want to use. The SDK may consist of several “bundles”, one per Chrome/Pepper version (see versioning information). A convenience Makefile rule called serve is the easiest way to invoke it: To simulate a production environment, the SDK provides a simple web server that can be used to serve the application on localhost.

Step 1: Download and install the Native Client SDKįollow the instructions on the Download page to download and install the Native Client SDK. It is also similar to the way web workers interact with the main document in JavaScript. The Native Client messaging system is part of the Pepper API, and is described in detail in Developer’s Guide: Messaging System. This behavior is analogous to client/server communication on the web, where the client posts a message to the server and returns immediately. In all cases, the communication is asynchronous: The caller (JavaScript or the Native Client module) sends a message, but the caller does not wait for, or may not even expect, a response. Both sides can initiate and respond to messages. The Native Client programming model supports bidirectional communication between JavaScript and the Native Client module. Communication between JavaScript and Native Client modules A JavaScript alert panel displays the message received from the Native Client module. If it is, the Native Client module returns a message saying 'hello from NaCl'. When the Native Client module receives a message, it checks whether the message is equal to the string 'hello'. In this simple application, the JavaScript sends a 'hello' message to the Native Client module.

The application in this tutorial shows how to load a Native Client module in a web page, and how to send messages between JavaScript and the Native Client module.

What the application in this tutorial does It’s recommended that you read the Native Client Technical Overview prior to going through this tutorial. The PNaCl toolchain is used to enable running the Native Client module directly from a web page. This is a client-side application that uses HTML, JavaScript and a Native Client module written in C++.
