Kraph (or Katta-Graph) is a simple project to take notes in a graph structure. I started from the need, at a Dungeons and Dragons table, to take notes about various npcs, places, facts, and objects. I needed an evidence board that was easy to use for my less-IT-savy companions. Thus, I thought about a program that can run in the browser. In order to not incur in privacy problems, I did not want to have a server at all. A serverless application in the browser. This allows anybody, with a connection and a PC, to take notes at the table. After investigating various alternatives: javaScript, mobile, Rust, I landed on WebAssembly and JavaScript. The advantages of this approach:
- Nothing to install.
- Cheap: free github pages.
- The graph can be donwnloaded/uploaded to save progress.
Since it is serverless, everything can be hosted on the github pages.
Adapt the project to be used on mobile.
- src: Place your C++ source and header files here.
- build: Output directory for build artifacts.
In order to compile the project you need the cheerpj compiler. The free verions works like a charm.
To build the project, you can use CMake and Ninja:
cmake -G Ninja . -DTESTS=ON -B build && cmake --build build && ./build/tests
cmake -G Ninja . -DTESTS=OFF -B build && cmake --build build && cmake --install build && python3 -m http.serverIn order to make git auto-format when you push you need to link the pre-commit in the .git folder:
ln -s pre-commit .git/hooks/pre-commitWith the github actions a new, updated version of the program is deployed automatically every time there is a push to main.
Testing removes all the glue/javaScript code and you can test with the standard google tests.
