Architecture

Front end

• The front end is written in typescript, using a react-like framework called inferno. All UI elements are reusable .tsx components.
• The main page and routing are in ui/src/index.tsx.
• The components are located in ui/src/components.

Back end

• The back end is written in rust, using diesel, and actix.
• The server source code is split into main sections in server/src. These include:
  • db - The low level database actions.
    • Database additions are done using diesel migrations. Run diesel migration generate xxxxx to add new things.
  • api - The high level user interactions (things like CreateComment)
  • routes - The server endpoints .
  • apub - The activitypub conversions.
  • websocket - Creates the websocket server.

Linting / Formatting

• Every front and back end commit is automatically formatted then linted using husky, and lint-staged.
• Rust with cargo fmt and cargo clippy.
• Typescript with prettier and eslint.
