🌐 Web query:
VS Code remote development webview iframe localhost port forwarding WebviewPanel remote extension host localhost
💡 Result:
When developing VS Code extensions for remote environments (such as SSH, Containers, or GitHub Codespaces), accessing a localhost web server inside a WebviewPanel requires special handling because webviews run in an isolated context on the user's local machine, while the extension host runs on the remote server [1][2]. Simply referencing localhost inside the webview will resolve to the user's local machine, not the remote host [1][2]. To bridge this gap, you should use one of the following approaches based on your requirements: 1. vscode.env.asExternalUri (Recommended for iframes) This is the most reliable method for loading content into an iframe within a webview [3]. It programmatically converts a local URI into an external, accessible URI that VS Code routes through its remote tunneling infrastructure [1][4]. Example: const serverUri = await vscode.env.asExternalUri(vscode.Uri.parse('http://localhost:3000')); panel.webview.html = <iframe src="${serverUri}"></iframe>; 2. Webview portMapping If you do not intend to support the browser-based editor (e.g., Codespaces web) and only need support for the VS Code desktop client, you can use the portMapping option in your WebviewOptions [1][4]. This maps a port inside the webview to a specific port on the remote host [2][4]. Example: const panel = vscode.window.createWebviewPanel( 'example', 'Example', vscode.ViewColumn.One, { enableScripts: true, portMapping: [{ webviewPort: 3000, extensionHostPort: 3000 }] }); Important Limitations: - WebSockets: Port mapping does not support WebSocket connections [5]. If your webview requires WebSockets, you must use other communication channels, such as the VS Code message passing API (postMessage/onDidReceiveMessage) between the webview and the extension host [6][5]. - Browser-based Editors: The portMapping approach is generally not supported in browser-based environments (like Codespaces in a web browser) [1][4]. In such cases, vscode.env.asExternalUri is the preferred, more compatible solution [1][3]. - Security: Always ensure your HTML content defines a proper Content Security Policy (CSP) to permit the loading of external resources [1][7].

Use a host-reachable URI for remote webviews. ChatPanel embeds the raw http://127.0.0.1:<port> URL from the extension host and does not use vscode.env.asExternalUri or portMapping. In Remote-Containers and Remote-SSH, the webview runs on the host, so 127.0.0.1 refers to the host, not the container or SSH host. Update lines 183-193 to describe the required host forwarding, or resolve the server URL with asExternalUri. The multiple-container claim is also incorrect because host-side webviews can collide when forwarded ports differ or overlap.

@jack-champagne, I recommend keeping this finding.
The current code puts the extension host URL, http://127.0.0.1:<port>, directly in the iframe src. In a Remote-Containers or Remote-SSH webview, that address resolves on the client by default. VS Code documents vscode.env.asExternalUri as the supported solution for this case: Supporting Remote Development and GitHub Codespaces.
The new documentation explicitly supports devcontainers. Therefore, the statements in docs/devcontainers.md about the webview reaching container-internal 127.0.0.1:43117 are not correct.
The appropriate resolution is to translate the iframe origin with vscode.env.asExternalUri and use the returned URI as the iframe URL. If remote devcontainers are intentionally unsupported, the documentation must state that limitation and remove the port-forwarding assurance.

Dispose every panel that uses the old origin.
ChatPanel.live includes panels created by openNew, but disposeCurrent() disposes only the primary panel. When notifyServerUrlChanged() returns true, extension.ts calls this method and recreates only ChatPanel.current. Side-by-side panels keep an iframe whose CSP and relay target still use the old origin. They cannot follow the new server after an ephemeral-port restart. Dispose or recreate every live panel whose origin differs before opening the new primary panel.

is this really a big lift? I presume its a polling checker and maybe a little error handling but nothing too bad
There was a problem hiding this comment.
@jack-champagne, no. “Heavy lift” overstates this finding.
This does not need polling. serverManager.onReady() already detects the new server URL.
The focused fix is:
- Add equivalent restart handling for
DeckPanel. - If
url.originis unchanged, keep the deck and forwardserver-url-changedto its panes. - If
url.originchanged, dispose the current deck. The next open recreates it with the newboot.originand CSP.
This is likely a small, contained lifecycle change across DeckPanel and the existing serverManager.onReady() callback. The main work is to verify panel recreation behavior and add coverage for same-origin and changed-origin restarts.

site:code.visualstudio.com/api/references/vscode-api asExternalUri cache returned URI tunnel changes
💡 Result:
In the context of the Visual Studio Code Extension API, developers are explicitly advised against caching the result of the vscode.env.asExternalUri function [1]. The primary reason for this guidance is that the resolved URI may become invalid due to system or user-initiated actions [1]. Specifically, when an extension is running in a remote environment, calling asExternalUri automatically establishes a port forwarding tunnel from the local machine to the remote resource [1]. Because the lifetime of this tunnel is managed by the editor and can be manually closed by the user at any time, any previously cached URI may no longer point to an active or valid tunnel [1]. Consequently, extensions should always invoke asExternalUri when needed rather than relying on a stored result [1].
Citations:
Resolve asExternalUri when opening each webview. opencodeExternalUrl can become invalid when VS Code closes or changes the forwarding tunnel. The current cache remains until the next server-ready event, so existing panels can become unusable. Refresh the URL and affected panels when the tunnel changes.

Decouple internal readiness from external URL resolution.
When vscode.env.asExternalUri(...) rejects, the handler stops before setting readiness, reconnecting SSE, notifying panels, or opening chat. Catch forwarding errors separately, continue internal readiness with url, and report the webview URL failure.

Resolve the external URL before opening any webview.
The bug-report fallback and fleet readiness path pass opencodeReadyUrl directly. Fleet readiness also does not set opencodeExternalUrl, so amicode.openChat, amicode.newChat, and amicode.chatDeck reject a ready fleet server. The fleet restart and other respawn paths can also leave the external URL undefined or stale. Centralize vscode.env.asExternalUri resolution and use the resolved URL for every ChatPanel and DeckPanel creation path.

Update DeckPanel on server URL changes.
The ready handler notifies only ChatPanel. Existing DeckPanel instances receive no server-url-changed message and keep stale iframes after a server origin change. Add equivalent notification and recreation handling for DeckPanel.

PR Notes: amicode — Server URL Push on Restart
Summary
Companion to the opencode PR (boot-ID + SSE resilience). Adds the extension-host
side of the "no GUI response" fix: when the server restarts, the extension host
notifies the webview immediately — and if the port changed (ephemeral mode),
recreates the panel so
location.originis correct.Changes
packages/extension/src/chat_panel.tsorigininstance field: records the URL origin the panel was built with.Used to detect port changes on restart.
notifyServerUrlChanged(url)static method: compares the new URL's originto the current panel's recorded origin.
server-url-changed(Lane 2) to all live panels as a"restart happened" signal.
true, signaling the caller to dispose and recreate.disposeCurrent()static method: disposes the underlyingvscode.WebviewPanel. The panel'sonDidDisposehandler cleans up internalstate (
ChatPanel.current,ChatPanel.live).Lane 2 allowlist:
"server-url-changed"added to the relay script's messagefilter, permitting the extension host to forward this message kind to the iframe.
packages/extension/src/deck/shell.ts"server-url-changed"messages are broadcast toall pane frames, consistent with how
thememessages are fanned out.packages/extension/src/extension.tsserverManager.onReadyhandler (the one that fires on allsuccessful server starts, including restarts): added URL-push logic.
ChatPanel.notifyServerUrlChanged(url).true(port changed), callsChatPanel.disposeCurrent()—the subsequent
openOrRevealcreates a fresh panel with the new iframe src.server-url-changedmessage is sufficient — theSSE reconnect loop + boot-ID detection handle the state refresh.
.devcontainer/devcontainer.json"amicode.opencodePort": 43117tocustomizations.vscode.settings,ensuring the port is pinned in devcontainer workflows.

Includes caveats for

Testing
amicode.opencodePort = 43117, the default):onReadyfires,

refresh.

true, panel is disposed,openOrRevealcreates a fresh panel with thenew URL. The fresh iframe's
location.originis correct from the start.onReadyfires, no existing panel →notifyServerUrlChangedreturnsfalse(no panel to notify).openOrRevealcreates the first panel normally.Related
