## Introduction
Tapeti is a wrapper for the RabbitMQ .NET Client designed for long-running microservices. It’s main goal is to minimize the amount of messaging code required, and instead focus on the higher-level flow.
@ -47,6 +48,17 @@ The documentation for Tapeti is available on Read the Docs:
[![Documentation Status](https://readthedocs.org/projects/tapeti/badge/?version=latest)](http://tapeti.readthedocs.io/en/latest/introduction.html?badge=latest)
## Related repositories
Parts of Tapeti have been split into their own repository. This allows them to have their own version numbers which increases compatibility between shared message packages when services use different Tapeti versions.
- [Tapeti.Annotations](https://github.com/MvRens/Tapeti.Annotations)
annotations used in message classes, like [Request]
- [Tapeti.DataAnnotations.Extensions](https://github.com/MvRens/Tapet.DataAnnotations.Extensions)
generic data annotation attributes useful in messages, like the [RequiredGuid] attribute
- [Tapeti.Cmd](https://github.com/MvRens/Tapeti.Cmd)
the standalone tool to manage RabbitMQ messages and queues, focused on Tapeti-compatible messages
## Builds
Builds are automatically run using AppVeyor, with the resulting packages being pushed to NuGet.

Tapeti.Cmd
==========
The Tapeti command-line tool provides various operations for managing messages and queues.
Some operations, like shovel, are compatible with all types of messages. However, commands like import and export can assume JSON messages, specifically those sent by Tapeti, so your results may vary.
Common parameters
-----------------
Most operations support the following parameters. All are optional.
-h <hostname>, --host <hostname>
Specifies the hostname of the RabbitMQ server. Default is localhost.
--port <port>
Specifies the AMQP port of the RabbitMQ server. Default is 5672.
-v <virtualhost>, --virtualhost <virtualhost>
Specifies the virtual host to use. Default is /.
-u <username>, --username <username>
Specifies the username to authenticate the connection. Default is guest.
-p <password>, --password <username>
Specifies the password to authenticate the connection. Default is guest.
Example:
::
.\Tapeti.Cmd.exe <operation> -h rabbitmq-server -u tapeti -p topsecret
Export
------
Fetches messages from a queue and writes them to disk.
-q <queue>, --queue <queue>
*Required*. The queue to read the messages from.
-o <target>, --output <target>
*Required*. Path or filename (depending on the chosen serialization method) where the messages will be output to.
-y, --overwrite
If the output exists, do not ask to overwrite.
-r, --remove
If specified messages are acknowledged and removed from the queue. If not messages are kept.
--skip <count>
Number of messages in the input to skip. Useful if a previous non-removing export was interrupted.
-n <count>, --maxcount <count>
Maximum number of messages to retrieve from the queue. If not specified all messages are exported.
-s <method>, --serialization <method>
The method used to serialize the message for import or export. Valid options: SingleFileJSON, EasyNetQHosepipe. Defaults to SingleFileJSON. See Serialization methods below for more information.
Example:
::
.\Tapeti.Cmd.exe export -q tapeti.example.01 -o dump.json
Import
------
Read messages from disk as previously exported and publish them to a queue.
-i <source>, --input <source>
Path or filename (depending on the chosen serialization method) where the messages will be read from.
-m <message>, --message <message>
Single message to be sent, in the same format as used for SingleFileJSON. Serialization argument has no effect when using this input. Be sure to quote the entire message, and escape quotes within the message with another quote.
-c, --pipe
Messages are read from the standard input pipe, in the same format as used for SingleFileJSON. Serialization argument has no effect when using this input.
-e, --exchange
If specified publishes to the originating exchange using the original routing key. By default these are ignored and the message is published directly to the originating queue.
--skip <count>
Number of messages in the input to skip. Useful if a previous import was interrupted.
-n <count>, --maxcount <count>
Maximum number of messages to import. If not specified all messages are imported.
-s <method>, --serialization <method>
The method used to serialize the message for import or export. Valid options: SingleFileJSON, EasyNetQHosepipe. Defaults to SingleFileJSON. See Serialization methods below for more information.
--maxrate <messages per second>
The maximum amount of messages per second to import.
--batchsize <messages per batch>
How many messages to import before pausing. Will wait for manual confirmation unless batchpausetime is specified.
--batchpausetime <seconds>
How many seconds to wait before starting the next batch if batchsize is specified.
Either input, message or pipe is required.
Example:
::
.\Tapeti.Cmd.exe import -i dump.json
Shovel
------
Reads messages from a queue and publishes them to another queue, optionally to another RabbitMQ server.
-q <queue>, --queue <queue>
*Required*. The queue to read the messages from.
-t <queue>, --targetqueue <queue>
The target queue to publish the messages to. Defaults to the source queue if a different target host, port or virtualhost is specified. Otherwise it must be different from the source queue.
-r, --remove
If specified messages are acknowledged and removed from the queue. If not messages are kept.
--skip <count>
Number of messages in the input to skip. Useful if a previous non-removing shovel was interrupted.
-n <count>, --maxcount <count>
Maximum number of messages to retrieve from the queue. If not specified all messages are exported.
--targethost <host>
Hostname of the target RabbitMQ server. Defaults to the source host. Note that you may still specify a different targetusername for example.
--targetport <port>
AMQP port of the target RabbitMQ server. Defaults to the source port.
--targetvirtualhost <virtualhost>
Virtual host used for the target RabbitMQ connection. Defaults to the source virtualhost.
--targetusername <username>
Username used to connect to the target RabbitMQ server. Defaults to the source username.
--targetpassword <password>
Password used to connect to the target RabbitMQ server. Defaults to the source password.
--maxrate <messages per second>
The maximum amount of messages per second to shovel.
--batchsize <messages per batch>
How many messages to shovel before pausing. Will wait for manual confirmation unless batchpausetime is specified.
--batchpausetime <seconds>
How many seconds to wait before starting the next batch if batchsize is specified.
Example:
::
.\Tapeti.Cmd.exe shovel -q tapeti.example.01 -t tapeti.example.06
Purge
-----
Removes all messages from a queue destructively.
-q <queue>, --queue <queue>
*Required*. The queue to purge.
--confirm
Confirms the purging of the specified queue. If not provided, an interactive prompt will ask for confirmation.
Example:
::
.\Tapeti.Cmd.exe purge -q tapeti.example.01
Declare queue
-------------
Declares a durable queue without arguments.
-q <queue>, --queue <queue>
*Required*. The queue to declare.
-b <bindings>, --bindings <bindings>
One or more bindings to add to the queue. Format: <exchange>:<routingKey>
Example:
::
.\Tapeti.Cmd.exe declarequeue -q tapeti.cmd.example -b myexchange:example.message myexchange:another.message
Bind queue
----------
Add a binding to an existing queue.
-q <queue>, --queue <queue>
*Required*. The name of the queue to add the binding(s) to.
-b <bindings>, --bindings <bindings>
One or more bindings to add to the queue. Format: <exchange>:<routingKey>
Example:
::
.\Tapeti.Cmd.exe bindqueue -q tapeti.cmd.example -b myexchange:example.message myexchange:another.message
Unbind queue
------------
Remove a binding from a queue.
-q <queue>, --queue <queue>
*Required*. The name of the queue to remove the binding(s) from.
-b <bindings>, --bindings <bindings>
One or more bindings to remove from the queue. Format: <exchange>:<routingKey>
Example:
::
.\Tapeti.Cmd.exe unbindqueue -q tapeti.cmd.example -b myexchange:example.message myexchange:another.message
Remove queue
------------

--confirm
Confirms the removal of the specified queue. If not provided, an interactive prompt will ask for confirmation.
--confirmpurge
Confirms the removal of the specified queue even if there still are messages in the queue. If not provided, an interactive prompt will ask for confirmation.
Example:
::
.\Tapeti.Cmd.exe removequeue -q tapeti.cmd.example
Serialization methods
---------------------
For importing and exporting messages, Tapeti.Cmd supports two serialization methods.
SingleFileJSON
''''''''''''''
The default serialization method. All messages are contained in a single file, where each line is a JSON document describing the message properties and it's content.
An example message (formatted as multi-line to be more readable, but keep in mind that it **must be a single line** in the export file to be imported properly):
::
{
"DeliveryTag": 1,
"Redelivered": true,
"Exchange": "tapeti",
"RoutingKey": "quote.request",
"Queue": "tapeti.example.01",
"Properties": {
"AppId": null,
"ClusterId": null,
"ContentEncoding": null,
"ContentType": "application/json",
"CorrelationId": null,
"DeliveryMode": 2,
"Expiration": null,
"Headers": {
"classType": "Messaging.TapetiExample.QuoteRequestMessage:Messaging.TapetiExample"
},
"MessageId": null,
"Priority": null,
"ReplyTo": null,
"Timestamp": 1581600132,
"Type": null,
"UserId": null
},
"Body": {
"Amount": 2
},
"RawBody": "<JSON encoded byte array>"
}
The properties correspond to the RabbitMQ client's IBasicProperties and can be omitted if empty.
Either Body or RawBody is present. Body is used if the ContentType is set to application/json, and will contain the original message as an inline JSON object for easy manipulation. For other content types, the RawBody contains the original encoded body.
Below is a bare minimum example, assuming Tapeti style messages and the default direct-to-queue import (no --exchange parameter). Again, keep in mind that it **must be a single line** in the export file to be imported properly.
::
{
"Queue": "tapeti.example.01",
"Properties": {
"ContentType": "application/json",
"Headers": {
"classType": "Messaging.TapetiExample.QuoteRequestMessage:Messaging.TapetiExample"
}
},
"Body": {
"Amount": 2
}
}
Actual file contents will thus look like:
::
{ "Queue": "tapeti.example.01", "Properties": { "ContentType": "application/json", "Headers": { "classType": "Messaging.TapetiExample.QuoteRequestMessage:Messaging.TapetiExample" } }, "Body": { "Amount": 2 } }
EasyNetQHosepipe
''''''''''''''''
Provides compatibility with the EasyNetQ Hosepipe's dump/insert format. The source or target parameter must be a path. Each message consists of 3 files, ending in .message.txt, .properties.txt and .info.txt.
As this is only provided for emergency situations, see the source code if you want to know more about the format specification.
Generating an example
---------------------
The "example" operation is available to generate an example message in SingleFileJSON format.
::
.\Tapeti.Cmd.exe example
To save the output to a file:
::
.\Tapeti.Cmd.exe example > example.json
Tapeti.Cmd has been moved to it's own repository at https://github.com/MvRens/Tapeti.Cmd. Along with it, the documentation is now available at https://tapeticmd.readthedocs.io/.
