Compact.js

Compact.js provides a TypeScript-based execution environment for smart contracts compiled with the Compact compiler. When a Compact smart contract is compiled, the output includes a JavaScript file and a TypeScript declaration file.

Compact.js uses these files at runtime to execute the circuits. The circuit execution results are then used by higher-level tools and frameworks (such as Midnight.js) to create and submit transactions to the Midnight blockchain.

For more information, see the Compact language documentation.
