Hello, and welcome to DiscordCoreAPI! This is a Discord bot library, written in C++, that leverages custom asynchronous CoRoutines, as well as a home-brew set of Https, WebSocket, and Datagram socket clients - all to deliver the utmost performance and efficiency for your bot. It uses roughly 0.1% of an Intel i7 9750h CPU to stream audio in high quality (Opus @ 48Khz, 16-bit) to a single server.

Documentation/Examples

This is a link to the Discord server!

A template for utilizing this library.

• Using the discord_core_api::snowflake::toEntity() function of the snowflake class allows for converting the entity's id directly into the data structure represented by it.

discord_core_api::snowflake someChannelId{};
discord_core_api::channel_data newChannel = someChannelId.toEntity<discord_core_api::channel_data>();
std::cout << "CHANNEL NAME: " + newChannel.name << std::endl;

• Thanks to utilizing Erlang Text Format for websocket transfer, and a pool of kept-alive HTTPS connections - this library offers the snappiest responses to your interactions and user input.

• Connect multiple voice-channels to one-another using the StreamInfo member of the VoiceConnectInitData structure, with the VoiceConnection class.

• It only uses about 0.1% of an Intel i7 9750h to stream audio in high quality (Opus 48Khz 16-bit Stereo) to a single server.

• All of the Discord API endpoints are covered in this library, including voice communication.

• As a result of using custom asynchronous coroutines along with a thread pool, this library has the ability to make fully asynchronous/concurrent requests to the Discord API.

• Guarantees that the order in which HTTPS requests are executed is the same that they were submitted in - despite being launched across different threads, while never infracting on any of the Discord API's rate-limits and while running concurrently across all of the endpoints.

• User interactions (Application Commands, Message Commands, User Commands) are accepted via the event_manager::onInputEventCreation event.
• They can all be responded to using the input_events::respondToInputEventAsync() function.
• Alternatively you can implement your own input-event handling by using the raw event_manager::onInteractionCreation or event_manager::onMessageCreation events.

EmbedData newEmbed{};
newEmbed.setAuthor(args.eventData.getUserName(), args.eventData.getAvatarURL());
newEmbed.setDescription("------\\n__**Sorry, but there's already something play
ing!**__\\n------");
newEmbed.setTimeStamp(getTimeAndDate());
newEmbed.setTitle("__**Playing Issue:**__");
newEmbed.setColor(discordGuild.data.borderColor);
RespondToInputEventData dataPackage{ args.eventData };
dataPackage.addMessageEmbed(newEmbed);
dataPackage.setResponseType(InputEventResponseType::Ephemeral_Interaction_Response);
InputEventData newEvent = input_events::respondToInputEvent(dataPackage);
input_events::deleteInputEventResponseAsync(newEvent, 20000).get();

• Install vcpkg, if need be.
• Make sure to run vcpkg integrate install.
• Enter within a terminal vcpkg install discordcoreapi:x64-windows_OR_linux.
• Set up a console project in your IDE and make sure to set the C++ standard to C++20 or later - and include discordcoreapi/Index.hpp.
• Build and run!

• CMake (Version 3.20 or greater)
• NOTE: I installed these using the vcpkg installer.
• DiscordCoreAPI (.\vcpkg install jsonifier:x64-windows_OR_linux)
• OpenSSL (.\vcpkg install openssl:x64-windows_OR_linux)
• Opus (.\vcpkg install opus:x64-windows_OR_linux)
• Sodium (.\vcpkg install libsodium:x64-windows_OR_linux)

• Install the dependencies.
• Clone this git repository into a folder.
• Set, in CMakeLists.txt, the _VCPKG_ROOT_DIR, or the Opus_DIR, unofficial-sodium_DIR paths to wherever each of the respective dependency files are located and they are as follows:
  • Opus_DIR # Set this one to the folder location of the file "OpusConfig.cmake".
  • unofficial-sodium_DIR # Set this one to the folder location of the file "unofficial-sodiumConfig.cmake".
  • OPENSSL_ROOT_DIR # Set this one to the folder location of the include folder and library folders of OpenSSL.
• Open a terminal inside the git repo's folder.
• Run cmake -S . --preset Linux_OR_Windows-Debug_OR_Release.
• Then run cmake --build --preset Linux_OR_Windows-Debug_OR_Release.
• Run within the same terminal and folder cmake --install ./Build/Debug_OR_Release.
• The default installation paths are: Windows = "ROOT_DRIVE:/Users/USERNAME/CMake/DiscordCoreAPI", Linux = "/home/USERNAME/CMake/DiscordCoreAPI"

• By running cmake --install ./Build/Debug_OR_Release, you will be given a cmake package, which can be used to build from this library, using other cmake projects.
• It is used by setting DiscordCoreAPI_DIR to wherever the DiscordCoreAPIConfig.cmake file would have been installed on your system by having run the cmake --install command, and then using find_package() on DiscordCoreAPI.
• When found, you will be granted the following cmake "variables"; DiscordCoreAPI - this is the library target which can be linked to from other targets in cmake, and on Windows; $<TARGET_RUNTIME_DLLS:DiscordCoreAPI-Bot> - which is a list of dll files to be copied into your executable's final location after building. As well as RELEASE_PDB_FILE_PATH, DEBUG_PDB_FILE_PATH, RELEASE_PDB_FILE_NAME, and DEBUG_PDB_FILE_NAME, which are full file/directory paths/filenames to the library's PDB files.
• Here and here is an example of building an executable from this library with this method.

• Download the bot template or create your own with the same imports, and set within it either the VCPKG_ROOT_DIR, or the CMAKE_CONFIG_FILE_DIR, Opus_DIR, and unofficial-sodium_DIR paths to wherever each of the respective dependency files are located and they are as follows:
  • CMAKE_CONFIG_FILE_DIR # Set this one to the folder location of the DiscordCoreAPIConfig.cmake generated while running CMake --install.
  • Opus_DIR # Set this one to the folder location of the file "OpusConfig.cmake".
  • unofficial-sodium_DIR # Set this one to the folder location of the file "unofficial-sodiumConfig.cmake".
  • OPENSSL_ROOT_DIR # Set this one to the folder location of the include folder and library folders of OpenSSL.
• Set up a main.cpp like this one, including the header discordcoreapi/Index.hpp.
• Run in a terminal from within the same folder as the top-level CMakeLists.txt, cmake -S . --preset Linux_OR_Windows-Debug_OR_Release.
• Then run cmake --build --preset Linux_OR_Windows-Debug_OR_Release.
• Run within the same terminal and folder cmake --install ./Build/Debug_OR_Release.
• The default installation paths are: Windows = "ROOT_DRIVE:/Users/USERNAME/CMake/Bot-Template-For-DiscordCoreAPI", Linux = "/home/USERNAME/CMake/Bot-Template-For-DiscordCoreAPI"

I am currently working on getting this thing to be used by people like you! So, if you have any suggestions for the library that would make it more usable - don't hesitate to let me know! I can be easily found on the Discord server that is linked to above! Cheers and thanks for your time.
