Native Node Modules

Since v???, the electron version of Riot can make use of native node modules. These allow Riot to integrate with the desktop in ways that a browser cannot.

While handy, these modules must be compiled and are thus downloaded pre-compiled during build so that a single OS can compile Riot for all platforms. If you would like to compile the native node modules from source, as is done for Riot releases, instead of trusting binaries hosted on npm, then please read on.

Do note that compiling a module for a particular operating system (Linux/Mac/Windows) and will need to be done on that operating system.

Compiling iohook

iohook is a native node module written in C/C++ that allows for cross-platform capturing of keystrokes. This is used for providing Push-to-Talk functionality (pressing a key to toggle the microphone in a call) and is ONLY enabled during a call and while setting the keybinding in settings.

If you would like to rebuild the module yourself and replace the downloaded binaries, then first make sure you have the following dependencies:

Common:

  • npm, yarn

Linux:

  • apt install build-essentials cmake

MacOS:

  • Xcode developer tools
  • brew
  • Then brew install cmake automake libtool pkg-config

Windows:

  • unsupported

Then simply execute build-native-modules.sh with the following flags:

./scripts/build-native-modules.sh -e 4.2.6 -a 69 -i

-e specifies the electron version. Note that the latest electron version can always be found in riot-web's package.json. -a specifies the electron ABI version, and -i tells the script to build iohook and then install it.

If you'd just like to build the module without installing it, use -I instead.

./scripts/build-native-modules.sh -e 4.2.6 -a 69 -I

To start Riot web, use npx electron .. To package, use build -wml -ia32 --x64.
