Hi all,

I would like to know what configurations are required to make may services run each on separate nodes.
My app is a RESTful webservice with gateway.service.js as well as 6 other services which each serve an API endpoint.
How can I canfigure moleculer such that each of my services runs on a different node.

M other question is how to condigure my Dockerfile such that each of my services run on a separate container.
Is this possible?,
is this a good idea?

Hi all,
In Web gateway, can I have multiple aliases (on a same route, same path, same params) for different mime-types?
I tried type "type" property (using "text/plain") for instance... but the gateway will route requests to the last alias' action. That's quite obvious since the aliases object is an object and not an array... so I nearly have the answer to my question. But maybe there is a trick...?
thanks

Hi all,
i am trying to add $$strict =true in params validation in action it is not working ,
``
am i messing somthing ?

actions : {
     getOne: {
          params: {
            $$strict: true,
            id: { type: "string", optional: true },
            name: { type: "string", optional: true },
          },
          handler: this.getOne
        }
}

Emmanuel SELLIER

@esellier

Not sure you need $$strict
that works for me:
const payload = {
"body" : bodyStruct,
"query": { type:"any", optional:true },
"params": { type: "object", strict:true, props: {token:{type:"string",optional:false}}}
}

BTW, does someone know if there is a Slack community with devs using moleculer?

@icebob Hi, I have two different nodes 'node1', 'node2'. both the nodes are running in two different instances with port 3000, 3001.
Each individual working as expected. Now i want to have a common end point like a api-gateway with port 3002 which can call both apis in port 3000 and 3001.
Do i need to create aliases and methods with ct.call('<Service name>') or is there a way i can redirect based on the path and expose both instances end points to single end point

Hi, i need to populate field
i used like this

settings: {
    populates:{ 
      "categories": "categories.get"
    }
}

this.adapter.find({
        query : {
          status: 2,
          _id: project_id
        },
        populate : ['categories']
      });

but it doesne't work

i need data like this
[
        {
            "status": 2,
            "name": "Test Name"
            "categories": [
                {
                    "_id": 1,
                    "name": "Collectibles"
                },
                {
                    "_id": 34,
                    "name": "watch"
                }
            ]
        }
]
instead it returns like this
[
        {
            "status": 2,
            "name": "Test Name"
            "categories": [1,34]
        }
]

Hi guys,

I am trying to authenticate some routes and not others.
anyone has an idea?

/api/users
/api/posts

@neer14

@fabrigeas
documentation says fields are for filter

@fabrigeas
auth:false ?

*authorization: false

You can use youse dependencies to make a service depend on another.

you can also register an event and wait for service A to be created, then run a given funtion in your service B

Hi guys,
how can I set the cookies in the request header from the service.action?
I am implementing a signin action from my users service and I would like to return an access-token in the header from the action.
Anyone has an idea?

@IngwiePhoenix

Hello there! I am coming here off the back of a StackOverflow question I asked in regards to microservice architecture. Basically, while I was planning my application, I had initially planned it to spawn multiple processes, each holding a service. Each service would need to communicate with one another either by calling methods directly or sending events to a queue so that other services pick them up and process accordingly. Now, all the Moleculer examples I have come across so far have either shown various services in Docker-Compose being networked through NATS or a single broker hosting multiple services. Now, how would I go about having Moleculer spawn, for instance three, processes? Since each service represents one service, let's just call them chat, notifications and users. Any idea? Thanks!

Hello, how to disable the default route in moleculer-web? (https://github.com/moleculerjs/moleculer-web/blob/master/src/index.js#L64)

@icebob I want to use the Datadog tracer, but I'm just getting individual service calls, but I'm interested in the whole flow (from input event to output). Is there a straightforward setup for this? Or should I create child/sub-child spans for every action called through the flow?

I see, that you have something similar in Moleculer documentation (https://moleculer.services/docs/0.14/tracing.html#Datadog)

Hey @icebob
How can i use the socket instance inside other services? I can see that this.io is available in started() life cycle method.
How to obtain that instance in other services? I'm using the below example

Hi. Can someone guide me through moleculer communication protocol.
I am facing Protocol Version Mismatch error.
I am not able to find the cause for this error.
The packet version is coming to be 4
and service broker version is coming 3.

André Mazayev

@AndreMaz

The protocol mismatch means that some of your nodes use moleculer v0.13 and others v0.14. v0.13 uses protocol version v3 while v0.14 uses protocol version v4.
They are incompatible (https://github.com/moleculerjs/moleculer/blob/master/CHANGELOG.md#communication-protocol-has-been-changed)

Hi. I'm using a file upload endpoint with moleculer-web... I'm parsing the stream coming to the action but after that the response returning is always wrapped inside an array... Is there a way to avoid that?
