Service Bus queues and dead-letter queues, inside VS Code

Service Bus in the editor: cloud namespaces and the local emulator in one tree, peek of a whole queue without locks, search in bodies and properties, and a whole dead-letter queue moved back in one operation. Works with Azure Service Bus and the Service Bus emulator.

Queue Studio for Azure Service Bus in VS Code: 24 messages peeked from the orders queue on the local emulator, with the selected message’s JSON body and its application and broker properties

Features

Free

Connections: a connection string (kept in VS Code's secret storage), a fully qualified namespace with Microsoft Entra ID (default Azure credential or Azure CLI), or the local emulator.
Tree: queues with active, scheduled and dead-letter counts, topics with their scheduled count, subscriptions with active and dead-letter counts; every queue and subscription has its dead-letter queue.
Peek: walks a whole queue, subscription or dead-letter queue by sequence number, in pages, up to a limit you set. Nothing is locked, so delivery counts and consumers are not affected. Session-enabled entities are read one session at a time, which locks that session while it loads. The table shows sequence number, message id, enqueue time, delivery count, subject, content type, size, session, state and application properties; the detail shows the body (JSON formatted and coloured) and every property.
Send: body, content type, subject, message and correlation id, application properties, session id, time to live and scheduled enqueue time. Resend fills the form from a selected message.
Entities: create and delete queues, topics and subscriptions; edit max delivery count, lock duration, time to live, dead-lettering on expiration and forwarding of queues and subscriptions, and the default time to live of topics.

Pro

Search: searches the peeked messages by substring or regular expression, with or without match case, in bodies, application properties (name=value) or both.
Move a whole dead-letter queue: moves it back to its queue, or to its topic for a subscription, or to any queue or topic. Each batch is sent first and removed from the dead-letter queue only after the send succeeded, so a failed send leaves the messages where they were; if removing a sent message fails, it is reported and may then be in both places. Progress is shown and the move can be cancelled.
Move or delete selected messages: to reach them, messages are received from the start with a lock and the others are released; on a main queue each released message counts one more delivery, and the confirmation says so. A selected scheduled message of a queue is scheduled on the target for the same time and then cancelled when moved, and cancelled when deleted.
Purge: purges a queue, a subscription, a dead-letter queue or one session. Scheduled and deferred messages stay.
Export: exports selected or shown messages to JSON or NDJSON, and sends messages from such a file.

A 14-day trial of everything starts with the first run. After it, Pro needs a license key.

The dead-letter queue of orders with six messages; the detail pane shows the dead-letter reason PaymentDeclined and its description next to the body — A dead-letter queue, with the reason and description of each message.

Moving all messages of orders/$deadletterqueue: a picker offers the orders queue they came from, two other queues and a topic; behind it, a dead-lettered message with the reason PaymentDeclined — Move All Back offers the queue the messages came from, or any other queue or topic.

A search for HD-990 in the bodies and properties of the orders queue: 6 of 30 messages match — Search in bodies and properties: 6 of 30 messages match.
