Default shade.files.client(peer) requires both peers to be mutually
addressable over HTTP — the response round-trips through
Shade.deliverControlEnvelope (POST to peer's /v1/transfer/control).
Browser tabs can't host an HTTP server, so they couldn't consume
@shade/files at all. Dispatch's filutforsker (admin-panel browser UI)
is the canonical use-case.
This release adds a parallel request-response transport: one POST per
RPC, encrypted envelope in the body, encrypted response in the same
HTTP response. No inbound channel needed on the client.
### New API
- shade.files.rpcRoute(opts?) — Hono app exposing POST /rpc.
- shade.files.httpClient(peer, opts) — request-response FileClient.
- FilesNamespace.serve(handler, { inlineOnly: true }) — skip streams-
bridge (and its configureTransfers pre-condition); also skip
channel-based dispatch so requests aren't double-dispatched.
### Limitations (v1)
Inline only (≤ 256 KiB). Streamed reads/writes throw clear errors
directing to shade.files.client(peer) on a server-to-server deploy.
### Tests
7 integration tests in tests/integration/http-rpc.test.ts covering
round-trip + negative cases (sender header, empty/garbage body,
maxBodyBytes, rpcRoute-without-serve).
### Symmetry
Mirrors @shade/server's shade-auth-middleware: encrypted envelope in
request body, decrypted via existing ratchet, response in same HTTP
roundtrip. No WebSocket, no SSE, no outbound from server.
Wire-compatible. Source-compatible. Lockstep bump to 4.1.0.

@shade/transport-bridge
Transport-agnostic delivery for Shade: WS → SSE → long-poll, in priority
order, behind a single IncomingMessage interface.
import {
FallbackBridgeTransport,
WsBridge,
SseBridge,
LongPollBridge,
} from '@shade/transport-bridge';
const auth = { crypto, signingPrivateKey, address: 'bob' };
const bridge = new FallbackBridgeTransport([
new WsBridge({ baseUrl, auth }),
new SseBridge({ baseUrl, auth }),
new LongPollBridge({ baseUrl, auth }),
]);
await bridge.connect({
onMessage: (msg) => {
// msg: { from: string; bytes: Uint8Array; receivedAt: number; msgId?: string }
},
});
console.log(bridge.activeKind); // "ws" | "sse" | "long-poll"
Pair with createBridgeRoutes in @shade/inbox-server to expose the
matching /v1/bridge/{stream,poll,ws} endpoints. Full design + threat
model in docs/transport.md.
What it solves
Browser extensions, strict corporate proxies, and edge runtimes routinely block long-lived WebSockets. Apps that already use the Shade inbox shouldn't have to write three custom delivery paths to handle the realistic mix of hostile networks they ship into. This package is the canonical answer.
Status
V3.7. Stable wire format, additive change to @shade/inbox-server. See
CHANGELOG.
