Overview ¶
Package wasmrpc pkg/wasmrpc/bridge.go c3-vis-wasm `skywire cli` clients.
A wasm-visor runs in a browser tab and cannot open a TCP listener, so the connection is inverted: the tab dials the host over a single WebSocket, both ends wrap that one connection as a yamux session, and the HOST opens a fresh yamux stream per local `skywire cli` connection. The tab accepts each stream into its rpc.Server.ServeConn. So:
skywire --rpc 127.0.0.1:<port> visor info # drives one specific tab
and N tabs => N bridges on N ephemeral ports — driving multiple wasm-visors with the ordinary CLI. The host end is Bridge (this file); the tab end is ServeTab (tab.go), which the wasm-visor calls.

Functions ¶
func ServeTab ¶
func ServeTab(tabConn net.Conn, serve func(stream io.ReadWriteCloser)) error
ServeTab runs the TAB end of the bridge: it wraps tabConn (the tab's WebSocket to the host) in a yamux CLIENT, accepts the streams the host opens (one per `skywire cli` connection), and hands each to serve — typically a closure that calls rpc.Server.ServeConn(stream). It blocks until the session ends (the WS drops or Close is called on the underlying conn), then returns the error.
Pure Go (yamux + net), so it compiles for js/wasm as well as native — the wasm-visor calls it with a net.Conn wrapping a browser WebSocket.
Types ¶
type Bridge ¶
type Bridge struct {
// contains filtered or unexported fields
}
Bridge fronts ONE tab: a yamux session over the tab's WebSocket connection, plus a local TCP listener whose every accepted connection is piped to a fresh yamux stream (the tab serves net/rpc over it).
func NewBridge ¶
NewBridge wraps tabConn (the host side of the tab's WebSocket, as a net.Conn) in a yamux SERVER and opens a local TCP listener on 127.0.0.1:<port> (port 0 = an OS-assigned ephemeral port). Accepted cli connections are each piped to a new yamux stream. Close tears it all down.
