Application

The host application that the developer who uses Mechanoid is creating.

Modules

The WASM modules that developers who are creating code for this Application are writing.

Devices

Specific hardware devices such as displays or sensors that can be used by the Application and/or Modules. This can also include connections to networking devices such as WiFi or Bluetooth, and low-level hardware interfaces such as GPIO or I2C.

Interpreter

The Interpreter is an interface to whichever WebAssembly interpreter is to be used for this application. The default interpreter for Mechanoid is Wazero.

FileStore

The FileStore is an interface to where the modules for this application can be stored, so that they can be dynamically loaded. Currently supports flash memory using the LittleFS file system.
