Native Node Modules
For some features, the desktop 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/macOS/Windows) and will need to be done on that operating system. Cross-compiling from a host OS for a different target OS may be possible, but we don't support this flow with Riot dependencies at this time.
Adding Seshat support
Seshat is a native node library that adds support for local event indexing and full text search in E2E encrypted rooms.
Since Seshat is written in rust the rust compiler and cargo tool-chain need to be
installed before installing Seshat itself. After installing the compiler Seshat
support can be added using yarn inside the electron_app/ directory:
yarn add matrix-seshat
After this is done the electron version of riot can be run from the main folder as usual using:
yarn electron
If for some reason recompilation of Seshat is needed, e.g. when using a
development version of Seshat using yarn link, or if the initial compilation was
done for the wrong electron version, Seshat can be recompiled with the
electron-build-env tool. Again from the electron_app/ directory:
yarn add electron-build-env
Recompiling Seshat itself can be done like so:
yarn run electron-build-env -- --electron 6.1.1 -- neon build matrix-seshat --release`
Please make sure to include all the -- as well as the --release command line
switch at the end. Modify your electron version accordingly depending on the
version that is installed on your system.
