Proposed changes

The Meteor-built web client runs on DDPSDK and REST only, and Meteor's DDP client no longer ships to the browser.

The branch stacks eight commits, each meant to be extracted on its own. The first two are follow-ups to PRs that already merged, and the next three are prerequisites that also work in today's client:

  1. regression: spread and pace the session resume retries (follow-up to fix: keep the web session when a resume fails without refusing the token #43006)
    • Retries wait a random part of the backoff, so the clients of a server being redeployed don't come back together.
    • The backoff only grows once a retry has actually run.
  2. regression: log out locally when the SAML single logout can't start (follow-up to chore: log in and out through SAML without Meteor's accounts runtime #42921)
    • Any failure on the way to the identity provider falls back to the local logout instead of leaving the user logged in.
  3. test: drive e2e logins and method calls through the client's own entry points
    • The login helper and the TOTP spec use window.__rocketChatLoginWithToken / __rocketChatCallMethod, which both builds expose, instead of require('meteor/accounts-base') and window.Meteor.callAsync.
  4. fix: only end the session on a 401 that rejects the token
    • The REST client cleared the credentials on any 401 answer to a mutation. Now it only clears them on the authentication middleware's "You must be logged in to do this.", not on endpoint 401s such as rooms.hide for an inaccessible room.
  5. fix: only log out the session a forced logout names
    • A device logout from device management names its session. Every other open session of the user ignores it; a logout with no session still ends all of them.
  6. feat(ddp-client): expose the connection's retry count and next retry time
    • Adds retryCount and nextRetryAt to Connection, so the reconnect countdown can be shown again.
  7. refactor: run the client on DDPSDK and REST only, in the Meteor build too.
    • The modules in vite/native become the client's only implementation: accounts, connection, the DDP codec on npm ejson, the transport flag fixed to DDPSDK, and the storage switch.
    • The native accounts module takes over what accounts-base did:
      • the expired-token check on load;
      • the cross-tab storage poller;
      • a single owner for every login;
      • keeping the session after resume failures that don't refuse the token.
    • client/meteor/overrides/*, minimongo/*, watch.ts and user.ts are deleted.
    • No runtime meteor/* import is left under client/.
  8. chore: keep Meteor's DDP, accounts and mongo packages out of the browser bundle.
    • .meteor/packages applies to every architecture. A new local package, rocketchat:server-runtime, uses and implies the server runtime packages for the server arch only. rocketchat:mongo-config goes first, because it sets the connection options.
    • The browser closure drops from 73 to 29 Meteor packages: no ddp-client, ddp, mongo, minimongo, accounts-base, tracker, reload or autoupdate.
    • No Meteor package code is copied.
    • The new-version notice no longer comes from the autoupdate client. The client subscribes to the same meteor_autoupdate_clientVersions publication through DDPSDK. It fires client_changed when the server serves a different build than the one in __meteor_runtime_config__, so the notice and the dev reload keep working.

Issue(s)

https://rocketchat.atlassian.net/browse/ARCH-2576

Known gaps

  • Desktop app: Rocket.Chat.Electron reads Meteor.userId/user/status/call through window.require. Those no longer exist, so its integrations stop working. This needs an explicit desktop-api contract first.
  • Use_RC_SDK: the setting no longer has any effect on the client. Removing it is a separate breaking change.

Steps to test or reproduce

  • The CI e2e suite exercises login, presence, streams, method calls (including the TOTP spec, driven through the native callMethod), E2EE and SAML on a client with no Meteor DDP client.
  • Tested manually against a copy of a real database:
    • login and logout;
    • sessions across tabs;
    • a server restart with the tab open;
    • a stale token from another instance, which is refused and cleared.

Learning: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

164-170: Clear local login state only after the server confirms logout.

makeClientLoggedOut() still runs in a finally block. If the logout method fails, the client removes its credentials anyway. The server-side token then stays valid, and the client never revokes it. Clear local state when the call succeeds or returns an auth error. Rethrow all other errors.

1-72: LGTM!

Also applies to: 91-162, 172-257

86-88: 🩺 Stability & Availability

ConnectionImpl does not set status to reconnecting. reconnect() emits that event and then calls connect(). During the retry backoff, the status remains disconnected; connect() changes it to connecting before creating the WebSocket. The retry timer then exits when it sees connecting, so the claimed second connection path is not established.

Walkthrough

The client now uses DDPSDK and REST for account and method flows. SAML uses standalone helpers. The changes add a server-only Meteor runtime package and remove Meteor client adapters, local Minimongo code, and duplicate Vite-native modules.

Changes

Client transport migration

Layer / File(s) Summary
Server-only runtime package
apps/meteor/packages/rocketchat-server-runtime/*, apps/meteor/.meteor/packages, apps/meteor/.meteor/versions
A new Meteor package groups server runtime dependencies. The Meteor manifests reference it and meteor@2.3.1.
DDPSDK account and method transport
apps/meteor/client/meteor/accounts.ts, apps/meteor/client/meteor/connection.ts, apps/meteor/client/lib/sdk/*, apps/meteor/client/lib/isLoginTokenRefused.*, packages/ddp-client/src/Connection.ts, apps/meteor/tests/e2e/*
Account restoration uses explicit session state and retry handling. Methods use DDPSDK or REST. DDP parsing uses EJSON. Connection state exposes the next retry time.
SAML login and logout integration
apps/meteor/client/meteor/login/saml.ts, apps/meteor/client/providers/UserProvider/UserProvider.tsx, apps/meteor/client/views/root/SAMLLoginRoute*, apps/meteor/tests/mocks/client/meteor.ts
SAML login and logout use standalone helpers. The provider attempts identity-provider logout before local logout. Tests and mocks use the standalone token-login helper.
Remove Meteor client adapters and local Minimongo
apps/meteor/client/main.ts, apps/meteor/client/meteor/minimongo/*, apps/meteor/client/meteor/overrides/*, apps/meteor/client/meteor/user.ts, apps/meteor/client/meteor/watch.ts
The client entrypoint no longer imports the override bundle. Meteor overrides, local Minimongo modules, and user-watch helpers are removed.
Remove duplicate Vite-native adapters
apps/meteor/vite/native/*, apps/meteor/vite/vite.config.mts
The Vite-native account, connection, DDP protocol, login, SDK stand-in, and override modules are removed. The module-replacement comment is updated.

Merge Risk: 🔵 Low · up to b491b

Logging out while the server call fails still clears local credentials and leaves the server session token unrevoked. The connection status UI can also show a retry time that will not happen after a manual close. Both are narrow, low-impact issues that can be fixed or accepted before merge.

The targeted source inspection is required to determine whether Meteor guarantees the initialization order between rocketchat:mongo-config and accounts-base. The supplied evidence does not include the package declarations or the built server load order, so the claim cannot be decided.

Do not store an already-expired expiry when tokenExpires is missing.

The resume login response can omit tokenExpires. In that case, makeClientLoggedIn stores the current time as LOGIN_TOKEN_EXPIRES. The page-load check then removes the valid stored credentials.

Proposed fix
-	const tokenExpires = result.tokenExpires instanceof Date ? result.tokenExpires : new Date(result.tokenExpires?.$date ?? Date.now());
+	const tokenExpires =
+		result.tokenExpires instanceof Date ? result.tokenExpires : result.tokenExpires ? new Date(result.tokenExpires.$date) : undefined;

 	setStoredItem(STORAGE_KEYS.USER_ID, result.id);
 	setStoredItem(STORAGE_KEYS.LOGIN_TOKEN, result.token);
-	setStoredItem(STORAGE_KEYS.LOGIN_TOKEN_EXPIRES, tokenExpires.toString());
+	if (tokenExpires) {
+		setStoredItem(STORAGE_KEYS.LOGIN_TOKEN_EXPIRES, tokenExpires.toString());
+	} else {
+		removeStoredItem(STORAGE_KEYS.LOGIN_TOKEN_EXPIRES);
+	}

Clear local login state only after the server confirms logout.

logout calls makeClientLoggedOut() in a finally block. If the logout method fails (network error, timeout, server error), the client still removes USER_ID, LOGIN_TOKEN and LOGIN_TOKEN_EXPIRES. The error then propagates to the caller. The server-side login token stays valid but orphaned, and it is never revoked.

Meteor's accounts-base cleared client state only after a successful logout method call. This change widens that behavior.

Clear local state on success. Also clear it when the server reports an auth error, because the session is already invalid in that case. Rethrow other errors so the caller can retry or show a message.

Cancel the pending resume retry when a different login succeeds.

Only resumeStoredSession and makeClientLoggedOut clear resumeRetryTimer. makeClientLoggedIn does not clear it. The timer callback also does not check that token is still the stored token before it calls loginWithToken. The stale-token check at Line 125 runs only after a failed attempt.

The failure sequence is:

  1. A page-load resume for token A fails with a transient error, such as a 500 or a rate limit.
  2. The token is kept, and a retry is scheduled for up to 60 s later.
  3. Before the retry fires, the user logs in with credentials. This can be a different account. makeClientLoggedIn stores token B.
  4. The timer fires and calls loginWithToken(A). If token A is still valid, the call succeeds. makeClientLoggedIn then overwrites token B and the socket identity with account A.

As a result, the client silently switches to the old session.

Fix this in two places:

  • Clear the timer in makeClientLoggedIn.
  • In the timer callback, skip the retry when the stored token has changed.
Proposed fix
-		resumeRetryTimer = setTimeout(() => void resumeStoredSession(token).catch(() => undefined), resumeRetryDelay);
+		resumeRetryTimer = setTimeout(() => {
+			if (getStoredItem(STORAGE_KEYS.LOGIN_TOKEN) !== token) return;
+			void resumeStoredSession(token).catch(() => undefined);
+		}, resumeRetryDelay);

Also add this line to makeClientLoggedIn:

 const makeClientLoggedIn = (result: LoginResult): void => {
+	clearTimeout(resumeRetryTimer);
+	resumeRetryDelay = MIN_RESUME_RETRY_DELAY;

Clear nextRetryAt when the retry is cancelled.

nextRetryAt is reset only at the start of connect(). close() clears retryOptions.retryTimer, but it leaves nextRetryAt set. Consider a close that happens while a retry is scheduled, for example during the logout teardown. After that close, connection.nextRetryAt still reports a due time for an attempt that will never run. getConnectionStatus maps closed to waiting and passes this stale retryTime to the status UI.

Set this.nextRetryAt = undefined in close(). This matches the timer clear in that method.

Proposed fix
 	close() {
 		clearTimeout(this.retryOptions.retryTimer);
+		this.nextRetryAt = undefined;
 		this.status = 'closed';

136-136: Cancel the pending resume retry when a different login succeeds.

The issue from the previous review is still present. makeClientLoggedIn does not clear resumeRetryTimer. The timer callback also does not check whether token is still the stored token. Suppose a user logs in with credentials while a retry is pending. The retry can then call loginWithToken with the old token and replace the new session. To fix this, clear the timer in makeClientLoggedIn. Also make the callback return early if getStoredItem(STORAGE_KEYS.LOGIN_TOKEN) !== token.


153-158: Clear local login state only after the server confirms logout.

The issue from the previous review is still present. The finally block runs makeClientLoggedOut() even when the logout method fails. Local credentials are then removed, but the server-side token is not revoked.


42-59: LGTM!

Settle waitForConnection when the connection attempt fails.

When the status is connecting or reconnecting, waitForConnection waits only for connected. Connection.connect() can instead set the status to failed, emit disconnected, and reject its connection promise without emitting connected. If retries are exhausted or the socket closes, waitForConnection remains pending.

Then callLoginMethod does not reach its finally block. pendingLogins and loggingIn can remain set, and the storage poller keeps returning while loggingIn is true.

Observe connection failure and close events in waitForConnection, or add a bounded timeout, so every failed connection attempt settles the login.

Update waitForConnection to settle when the connection attempt fails or closes,
including attempts already in connecting or reconnecting states, by observing
the relevant failure/disconnected events or using a bounded timeout. Ensure all
failure paths clean up listeners and reject so callLoginMethod reaches its
finally block and clears pending login state.

Every client of a server being redeployed fails its resume at the same moment,
so retrying them on the same schedule sends them back together and can trip
the rate limits or IP login blocks again. Retries now wait a random part of
the backoff, and the backoff only grows once a retry has actually run, so a
second failure report doesn't push the next attempt further out.

Introduced by #43006
The identity-provider logout returned a rejected promise when anything after
the decision to use single logout threw: loading the SDK, the samlLogout call,
the storage or the redirect. The caller only logs out locally on a resolved
false, so the user stayed logged in. Those failures now resolve to false and
the local logout runs, as the Meteor.logout override did before.

Introduced by #42921
…y points

The login helper and the TOTP spec reached into Meteor's browser runtime with
require('meteor/accounts-base') and window.Meteor.callAsync, so they would break
as soon as the client stops loading those packages. The accounts and connection
modules now expose window.__rocketChatLoginWithToken and
window.__rocketChatCallMethod in both builds, and the specs use them. The call
paths under test don't change.
The REST client cleared the stored credentials on any 401 answer to a
mutation. Endpoints also answer 401 for their own reasons, such as hiding a
room the user can no longer access, and those logged the user out. The
session now only ends when the answer is the authentication middleware's
"You must be logged in to do this.", which is the one that says the token no
longer identifies a user.
Logging out one device from the device management list broadcasts a
force_logout with that device's session id. The server already closes only
that session, but the web client ignored the id, so every open session of the
user wiped its credentials. The client now compares the id with the one of
the connection it is logged in on, and only a logout that names it, or names
no session at all, ends the session.
A logout closed the SDK socket, which failed every method call on it. A forced logout that arrived after a new login had started failed that login with ConnectionLostError. The socket now stays open while a login is in progress, since that login authenticates it again.
…g in again

The reset logs the user out on its own schedule. Logging in before that logout arrives races with it.
…time

Status readers such as a reconnect countdown need to know how many attempts
were made and when the next one is due.
… too

The Vite build's native modules become the client's only implementation:
accounts, connection, the DDP codec, the transport flag and the storage switch.
Nothing on the client calls Meteor.connection, Accounts or Tracker anymore, so
the overrides that bridged them to DDPSDK go away, together with the local
minimongo, watch and user helpers that only those overrides used.

The TOTP end-to-end spec now drives the call through the client's callMethod,
exposed on window like __rocketChatSdk, since Meteor.callAsync was the bridge.
…ser bundle

.meteor/packages applies to every architecture, so the server's runtime
packages also shipped their client halves (ddp-client, accounts-base,
minimongo, tracker, reload, autoupdate). A local package now uses and implies
them for the server only; the client keeps meteor, the compilers, the
minifiers and dynamic-import. The browser closure drops from 73 to 29 Meteor
packages, none of them DDP.

The new-version notice came from the autoupdate client. The client now
subscribes to the same meteor_autoupdate_clientVersions publication through
DDPSDK and fires client_changed when the server serves a different build than
the one in __meteor_runtime_config__, so the notice and the dev reload keep
working.
