QUESTION

Integration between Node.js and ActiveMQ - how to use

Asked 2019-Dec-13 at 08:37

Background

I am studying ApacheMQ for a project where we need a message broker. Upon reading the official page I see some features that I am interested in:

Access to messaging Enterprise Integration Patterns (EIPs)
Support for the STOMP, AMQP, MQTT and OpenWire protocols

However, following the documentation, it is not clear to me if some of my objectives are possible.

Questions

I understand that in order to use ActiveMQ as a broker, I first need a messaging protocol. According to the documentation on language support for Node.js ActiveMQ only supports the STOMP protocol for Node.js.

Given that STOMP is a protocol, if I find a NPM library for any of the other protocols, can I use Node.js with that given protocol?
If such libraries exist, can you point some?
Are there any caveats in using Node.js and ActiveMQ with another protocol other than STOMP?

Regarding EIPs, I also need some clarification. After closer checking, I realized that EIPs can only be used via Apache Camel, a separate project with no support for anything other than Java.

Is it possible to use any of the EIPs that ActiveMQ offers with Node.js? If so, how?

It has been some time since I posted this, and for future reference I am posting my findings here. These findings relate my experience and as of the date of this post they are as accurate as possible.

Q1: Given that STOMP is a protocol, if I find a NPM library for any of the other protocols, can I use Node.js with that given protocol?

A1: The answer is yes. For example, using a MQTT library for Node.js, I can communicate with the ActiveMQ broker. There are usually some quirks that one has to considerate, but it definitely works.

Q2: If such libraries exist, can you point some?

A2:

MQTT: mqtt
AMQP 1.0 : amp10 and rhea. They don't work out of the box - see Unable to connect to Apache ActiveMQ with Node.js
STOMP: The recommended STMOPIT library.

Personally I would like to at least see the MQTT library added to the official documentation, as I believe it would help clear many questions from users.

Q3: Are there any caveats in using Node.js and ActiveMQ with another protocol other than STOMP?

A3: Yes. ActiveMQ has weird authentication requirements which lead to clients using a protocol's supported version to fail on connect (an example is with the previous AMQP 1.0 npm library). Furthermore, each library has its quirks, that you need to check. Usually the library's github page or issues page will give you some light on the integration issues with ActiveMQ, but it helps if the creators state clear support for ActiveMQ (which is not always the case).

Q4: Is it possible to use any of the EIPs that ActiveMQ offers with Node.js? If so, how?

A4: I believe this would still be possible via the REST DSL with XML (even though we don't use Spring nor anything like that) but I can't find anything nor anyone actually using it. The community failed to provide any feedback regarding this matter, as it seems to be very dependent on Java technologies, without knowledge in other other field.

Conclusion

Overall, if you have a Java project, you would be fine using ActiveMQ. If you want to use anything else, I strongly recommend avoiding it.

Everything either needs Java or some level of integration with it.

You could argue that ActiveMQ supports a large variety of protocols, but so do other tools that actually have support for your own language.

Even in the end, the EIPs provided by Camel, are not really available for for anything other than Java and even the community suggests you implement the patterns yourself, which defeats the whole purpose of using ActiveMQ.

QUESTION

How to use Apache Camel in Clustered Environment with Zookeeper and ActiveMQ

Asked 2019-Sep-27 at 15:58

I have 3 Servers (1 Master, 2 Slaves). Each of it have installed Zookeeper (latest version) and ActiveMQ (latest version, but not artemis). ActiveMQ is configured as Replicated Level-DB based on Zookeepers nodes.

Now I want to use Apache Camel for message routing.

Where should the Camel Route be located? I wrote a Spring Boot App but I want to have a failover like for ActiveMQ.

So i read about to put the jar into the activeMQ lib directory and setup an XML config Enterprise Integration Patterns

Another way is to use the Camel Components

Has anyone ever come across this problem before and want to share the solution?

...

Answered 2019-Sep-27 at 15:58

Uh oh, as mentioned in the comments, take care with the Level DB stuff since it is deprecated. Only use it if you have tested it thoroughly! In our tests, it was running quite nice. But when the level DB was, for whatever reason, corrupted, the data was lost. We were never able to restore a Level DB. Not very nice for production.

And don't even think about NFS based solutions. NFS is really not suited for this, we had a lot of issues in our tests. We often managed it for example to have multiple masters or no masters at all. So we gave it up.

In the end we are using a plain single broker because the complexity of solving issues in master/slave or replication setups can be quite high. And we had almost never any unplanned downtimes despite our "single point of failure".

However, a bunch of people told me that a network of brokers works quite well to have a redundant setup. At least one of them was talking about a really big environment.

Well, this is not really an answer to your question, isn't it?

You can put Camel routes beside the broker XML configuration and these routes then run inside the ActiveMQ process. See here for an example.

If you want to build a SpringBoot app to run the Broker, you simply need to make the Camel context available in Spring and it should be picked up.

QUESTION

Difference between Message Router and Content based Router in EIP

Asked 2017-Apr-12 at 13:42

I'd like to understand what exactly is the difference between the two Enterprise Integration Patterns

Content-Based Router

Message Router

The definition at camel documentation is suggestive that Content-Based router is a special case of Message Router. They why list them separately?

...

ANSWER

Answered 2017-Apr-12 at 08:53

As far as I understand the patterns Message Router only applies when the input and output is a queue or topic of a messaging system.

Content-based Router is not limited to messaging. I think you can say that inside a Message Router you have a Content-based router that decides which way to go.

In camel the decision is made using the choice() element.

If my assumption is correct then the documentation of the Message-Router at camel is wrong as it does not reflect the queues. I will check with the camel dev list and correct the wiki page if we agree on this.
