Interface ContextScopeOptions`Alpha`

Two knobs, both optional:

host, start a DOM walk from this element. Typical for components.
with, hand in fixed values for some context keys. Typical for tests or headless code that has no DOM host.

They compose: pass both and with overrides whatever the DOM provides for the named keys. Pass neither and get returns undefined for everything.

interface ContextScopeOptions {
host?: HTMLElement;
with?: Partial<ContextMap>;
}

Properties

host?: HTMLElement

Element to start looking from when resolving context keys that come from the DOM.

with?: Partial<ContextMap>

Fixed values for specific context keys. Wins over anything the DOM or a session-wide default would provide.
