How to script all the service broker elements for each database it is on, in the current server?

Question

I have service broker running on different servers.

Just recently I had to rebuild one of the test servers and it had a complete service broker solution running there.

For the next time I need to rebuild a server that has service broker running in any of its databases

I would like to script all the service broker architecture for that specific database

-- Message Types
SELECT * 
FROM sys.service_message_types;

Basically using the scripts below, how can I be able to script all the service broker elements for a particular database?

-- Message Types
SELECT * 
FROM sys.service_message_types;

-- Contracts
SELECT * 
FROM sys.service_contracts;

-- Queues
SELECT * 
FROM sys.service_queues;

-- Services
SELECT * 
FROM sys.services;

-- routes
SELECT * 
FROM sys.routes;


-- Endpoints
SELECT * 
FROM sys.endpoints;

After seeing a recent comment from David Browne:

SSDT / SqlPackage supports Service Broker objects.

I tried it out. I created some service broker objects based on the demo here:

• Configuring Service Broker for Asynchronous Processing

Then I download the DAC framework from here:

• Download Microsoft® SQL Server® Data-Tier Application Framework (18.0)

Then I ran this command (without the carriage returns):

sqlpackage 
  /Action:extract 
  /SourceServerName:.\instancename
  /SourceDatabaseName:AsyncProcessingDemo 
  /TargetFile:C:\scripts\sb.dacpac

Then I went to c:\scripts, right-clicked the dacpac file, and chose Unpack...:

This asked me for an output folder:

I clicked Unpack, went to that folder, and there were four files, including model.xml:

And sure enough, that .sql file contained a script for all the broker objects, assembled in almost the right order. It generated a script with the contract created before the message types it depends on. So you will end up with:

CREATE CONTRACT ... ([MessageType1] SENT BY INITIATOR, ...
GO
CREATE MESSAGE TYPE [MessageType1]...

You'll need to flip those around so the message types are created first.

I'm sure SqlPackage.exe and/or the DAC wizard has ways to restrict this to just the service broker objects, but this should be a good start.

Following on the accepted answer by Aaron Bertrand

and then the comments:

If you've run DacFramework.msi, you should be able to find SqlPackage.exe in C:\Program Files\Microsoft SQL Server\150\DAC\bin. – Aaron Bertrand

I run the following command from the location described above (without the carriage returns):

sqlpackage /Action:extract /SourceServerName:SQLPROD1 /SourceDatabaseName:COLA /TargetFile:"D:\Service Broker\COLA.dacpac"

and I got this result:

after that, opening the generated file, all database objects were scripted, including the service broker ones.
