The Link Tab

Same-origin browser tab transport for The Link. TabLink maps outbound events to a BroadcastChannel and publishes messages received from other channel members through its inbound tunnel.

Install

npm install @the-link/tab

Usage

Create the same namespace in every tab or window that should communicate.

import { TabLink } from "@the-link/tab"

const tabs = new TabLink("workspace")

tabs.$inbound.subscribe("document:changed", document => {
    console.log("Changed in another tab", document)
})

await tabs.$outbound.publish("document:changed", {
    id: "document-42",
    title: "The Link"
})

tabs.close()

The browser delivers a broadcast to other BroadcastChannel instances using the same namespace and origin. Payloads use the platform's structured-clone algorithm, so this transport does not apply the Core byte codec and does not require a server.

Calling close() leaves the namespace and releases the underlying BroadcastChannel.

Development

bun install --frozen-lockfile
bun run verify
