Modules

@tsonic/js provides the JavaScript ambient surface APIs most Tsonic JS-surface projects expect.

Major families

• console and process-keepalive helpers
• JSON
• Date, Math, Number, String, Boolean
• Map, Set
• typed arrays and array buffers
• reflection/object helpers
• timers
• error types such as RangeError

JSON

The public JSON API is typed:

type Message = { text: string };

const message = JSON.parse<Message>('{"text":"hello"}');
console.log(JSON.stringify(message));

Open-ended JSON object traversal is not the authoring model. Use concrete payload types, or receive broad values as unknown and narrow them explicitly.

Important framing

This section is not trying to be a full browser or Node reference manual. The package is documented here as a curated first-party JS surface for Tsonic.

Relationship to the manifest

The exported module/subpath set comes from the package manifest, not from a hand-waved “JS mode” concept.
