If you experience crashes or issues in Electron that you believe are not causedby your JavaScript application, but instead by Electron itself, debugging canbe a little bit tricky, especially for developers not used to native/C++debugging. However, using Visual Studio, Electron's hosted Symbol Server,and the Electron source code, you can enable step-through debuggingwith breakpoints inside Electron's source code.

Requirements

Building Electron is done entirely with command-line scripts and cannot be done with Visual Studio. You can develop Electron with any editor but support for building with Visual Studio will come in the future. Note: Even though Visual Studio is not used for building, it's still required because we need the build toolchains it provides. The setting is pretty self-explanatory, use the electron in nodemodules to run main.js. If you go to the Debug View and run Debug Main Process, you should see the code stopping at the breakpoints in main.js. Electron at that time needed street credibility and exposure as a new web development tool. It is a hybrid tool that grants web developers the ability to create desktop applications in a web environment, with ease of use. Microsoft was happy to champion their cause to get more exposure in web development circles. WPF and UWP are good enough.

  • A debug build of Electron: The easiest way is usually building ityourself, using the tools and prerequisites listed in thebuild instructions for Windows. While you canattach to and debug Electron as you can download it directly, you willfind that it is heavily optimized, making debugging substantially moredifficult: The debugger will not be able to show you the content of allvariables and the execution path can seem strange because of inlining,tail calls, and other compiler optimizations.

  • Visual Studio with C++ Tools: The free community editions of VisualStudio 2013 and Visual Studio 2015 both work. Once installed,configure Visual Studio to use Electron's Symbol server.It will enable Visual Studio to gain a better understanding of what happensinside Electron, making it easier to present variables in a human-readableformat.

Attaching to and Debugging Electron

To start a debugging session, open up PowerShell/CMD and execute your debugbuild of Electron, using the application to open as a parameter.

Setting Breakpoints

Then, open up Visual Studio. Electron is not built with Visual Studio and hencedoes not contain a project file - you can however open up the source code files'As File', meaning that Visual Studio will open them up by themselves. You canstill set breakpoints - Visual Studio will automatically figure out that thesource code matches the code running in the attached process and breakaccordingly.

Relevant code files can be found in ./shell/.

Attaching

You can attach the Visual Studio debugger to a running process on a local orremote computer. After the process is running, click Debug / Attach to Process(or press CTRL+ALT+P) to open the 'Attach to Process' dialog box. You can usethis capability to debug apps that are running on a local or remote computer,debug multiple processes simultaneously.

If Electron is running under a different user account, select theShow processes from all users check box. Notice that depending on how manyBrowserWindows your app opened, you will see multiple processes. A typicalone-window app will result in Visual Studio presenting you with twoElectron.exe entries - one for the main process and one for the rendererprocess. Since the list only gives you names, there's currently no reliableway of figuring out which is which.

Which Process Should I Attach to?

Code executed within the main process (that is, code found in or eventually runby your main JavaScript file) will run inside the main process, while othercode will execute inside its respective renderer process. V arranger 2 yamaha software download.

You can be attached to multiple programs when you are debugging, but only oneprogram is active in the debugger at any time. You can set the active programin the Debug Location toolbar or the Processes window.

Using ProcMon to Observe a Process

While Visual Studio is fantastic for inspecting specific code paths, ProcMon'sstrength is really in observing everything your application is doing with theoperating system - it captures File, Registry, Network, Process, and Profilingdetails of processes. It attempts to log all events occurring and can bequite overwhelming, but if you seek to understand what and how your applicationis doing to the operating system, it can be a valuable resource.
