gives you an overview of how to set up a development environment for BigBlueButton 2.7.</p> <h2 class="anchor anchorWithStickyNavbar_LWe7" id="before-you-begin">Before you begin<a href="#before-you-begin" class="hash-link" aria-label="Direct link to Before you begin" title="Direct link to Before you begin"></a></h2> <p>You first need to set up a BigBlueButton 2.7 server. See the instructions at <a href="/administration/install/">Install BigBlueButton 2.7</a>.</p> <h2 class="anchor anchorWithStickyNavbar_LWe7" id="overview">Overview<a href="#overview" class="hash-link" aria-label="Direct link to Overview" title="Direct link to Overview"></a></h2> <p>A BigBlueButton server is built from a number of components that correspond to Ubuntu packages. Some of these components are</p> <ul> <li>bbb-web -- Implements the BigBlueButton API and conversion of documents for presentation</li> <li>akka-bbb-apps -- Server side application that handles the state of meetings on the server</li> <li>bbb-html5 -- HTML5 client that loads in the browser. The client server-side Meteor application that leverages MongoDB and React.js</li> <li>bbb-learning-dashboard -- a live dashboard available to moderators, which displays user activity information that can be useful for instructors</li> <li>bbb-fsesl-akka -- Component to send commands to FreeSWITCH</li> <li>bbb-playback-presentation -- Record and playback script to create presentation layout</li> <li>bbb-export-annotations -- Handles capture of breakout content and annotated presentation download</li> <li>bbb-webrtc-sfu -- Server that bridges incoming requests from client to Kurento</li> <li>kurento-media-server -- WebRTC media server for sending/receiving/recording video (webcam and screen share)</li> <li>bbb-freeswitch-core -- WebRTC media server for sending/receiving/recording audio</li> </ul> <p>This document describes how to set up a development environment using an existing BigBlueButton 2.7 server. Once the environment is set up, you will be able to make custom changes to BigBlueButton source, compile the source, and replace the corresponding components on the server (such as updating the BigBlueButton client).</p> <p>The instructions in this guide are step-by-step so you can understand each step needed to modify a component. If you encounter problems or errors at any section, don't ignore the errors. Stop and double-check that you have done the step correctly. If you are unable to determine the cause of the error, do the following</p> <ul> <li>First, use Google to search for the error. There is a wealth of information in <a href="https://groups.google.com/forum/?fromgroups=#!forum/bigbluebutton-dev" target="_blank" rel="noopener noreferrer">bigbluebutton-dev</a> that has been indexed by Google.</li> <li>Try doing the same steps on a different BigBlueButton server.</li> <li>Post a question to bigbluebutton-dev with a description of the problem and the steps to reproduce. Post logs and error messages to <a href="https://pastebin.com" target="_blank" rel="noopener noreferrer">Pastebin</a> link them in your post.</li> </ul> <h4 class="anchor anchorWithStickyNavbar_LWe7" id="you-have-a-working-bigbluebutton-server">You Have a Working BigBlueButton Server<a href="#you-have-a-working-bigbluebutton-server" class="hash-link" aria-label="Direct link to You Have a Working BigBlueButton Server" title="Direct link to You Have a Working BigBlueButton Server"></a></h4> <p>Before you can start developing on BigBlueButton, you must install BigBlueButton (see <a href="/administration/install/">installation steps</a>) and ensure it's working correctly. Make sure there were no errors during the installation and that you can join a session successfully.</p> <p>We emphasize that your BigBlueButton server must be working <strong>before</strong> you start setting up the development environment. Be sure that you can log in, start sessions, join the audio bridge, share your webcam, and record and play back sessions -- you can verify this if you install <a href="/greenlight/v3/install/">Greenlight</a> or navigate to <a href="https://mconf.github.io/api-mate/" target="_blank" rel="noopener noreferrer">API MATE</a> using your server's secret and url.</p> <p>By starting with a working BigBlueButton server, you have the ability to switch back-and-forth between the default-packaged components and any modifications you make.</p> <p>For example, suppose you modify the BigBlueButton client and something isn't working (such as the client is not fully loading), you can easily switch back to the default-packaged client and check that it's working correctly (thus ruling out any environment issues that may also be preventing your modified client from loading).</p> <p><strong>Another Note:</strong> These instructions assume you have Greenlight installed so you can create and join meetings to test your setup.</p> <h4 class="anchor anchorWithStickyNavbar_LWe7" id="developing-on-windows">Developing on Windows<a href="#developing-on-windows" class="hash-link" aria-label="Direct link to Developing on Windows" title="Direct link to Developing on Windows"></a></h4> <p>To develop BigBlueButton from within Windows, you have two options:</p> <ul> <li>use Windows Subsystem for Linux</li> <li>use VMWare Player or VirtualBox to create a virtual machine (VM).</li> </ul> <p>Choose the OS to be Ubuntu 20.04 64-bit. The associated documentation for VMWare Player and VirtualBox or WSL will guide you on setting up a new 20.04 64-bit VM.</p> <p><strong>Note:</strong> When setting up the VM, it does not matter to BigBlueButton if you set up Ubuntu 20.04 server or desktop.
