eMAPI

This is a sample Electron app hosting GraphiQL connected to Electron-GqlMAPI. It is intended first as a code sample for CppGraphQLGen, but it aspires to be the spiritual successor to MFCMAPI. It is already quite powerful just by integrating GraphiQL, and it has the potential to add more diagnostic and debugging features in the future.

This project was originally based on cppgraphiql, but it has many upgrades to the build process, packaging, and the implementation since then. It is not cross-platform like cppgraphiql (which used a trivial service with mock data), but I intend to feed these improvements back into cppgraphiql. For now, this is a much better starting point if you want to implement your own Electron host for a CppGraphQLGen service.

Getting Started

To begin, you will need to satisfy the requirements for building GqlMAPI. If you are using Vcpkg to install CppGraphQLGen and GoogleTest as suggested in those instructions, then you will also need to save an npm config setting for CMake.js to use the vcpkg.cmake toolchain file:

> npm config set cmake_CMAKE_TOOLCHAIN_FILE %VCPKG_ROOT%\scripts\buildsystems\vcpkg.cmake

Then you can build and test the module using npm:

> npm install
> npm run electron-dev

Sample Queries

This query should return the display name and ID of all your MAPI stores:

query AllStores {
  stores {
    name
    id
  }
}

To get the default store you can sort the stores in descending order by the PR_DEFAULT_STORE property and then take just the top element:

query DefaultStore {
  stores @orderBy(sorts: [
      {
        property: {id: 13312},
        type: BOOL,
        descending: true
      }
  ]) @take(count: 1) {
    name
    id
  }
}

If everything is working, you should get results like this (minus the rectangles hiding personal information):
