Plan for Java/Node SDK?

[kination]

Hello,
Seems there are SDK for python. Don't you have plan for Java, or Node?

[ysimonson]

No plans, but happy to help anyone who wants to undertake the effort. Since it's all gRPC, building bindings would be straight-forward -- potentially no code would have to actually be written.

[kination]

@ysimonson yes, I've saw Python SDK, and it seems pretty simple to go on. Let me look around 🙏

[ysimonson]

Let me know if you have any questions!

[kination]

@ysimonson hello
I'm reviewing python-sdk to refer implementation. But it has been blocked as following

$ make init
...
fatal: clone of 'git@github.com:indradb/indradb.git' into submodule path '/Users/kination/workspace/oss/python-client/indradb_server' failed
Failed to clone 'indradb_server'. Retry scheduled
Cloning into '/Users/kination/workspace/oss/python-client/indradb_server'...
Enter passphrase for key '/Users/kination/.ssh/id_rsa': 

could you check this?

[ysimonson]

It's cloning a submodule, and asking for the passphrase to the SSH key that you use for git.

[kination]

@ysimonson oh, sorry. It was issue in my laptop. Thanks for quick feedback 🙏

@ysimonson hello.
Bit a long time, and started to work on node SDK.

There are some question, that when I call createVertex API, it always returns

{
      wrappers_: null,
      messageId_: undefined,
      arrayIndexOffset_: -1,
      array: [],
      pivot_: 1.7976931348623157e+308,
      convertedPrimitiveFields_: {}
}

Could you let me know whether it is correct or not?

Depend on proto file, CreateVertex should return CreateResponse

message CreateResponse {
    bool created = 1;
}

[kination]

There were sometimes returning expected value, such as returning true like below

{
      wrappers_: null,
      messageId_: undefined,
      arrayIndexOffset_: -1,
      array: [ true ],
      pivot_: 1.7976931348623157e+308,
      convertedPrimitiveFields_: {}
}

but most of cases it returns empty array data.
So my question is...

• How can I know if CreateVertex fails?
• How should I setup id for this? When I setup value as

const vert: IVertex = {
  id: "1234567890123456",
  identifier: "test"
}

it shows => uuid conversion failed: invalid length: expected 16 bytes, found 12

• Is this returns failure when using same id to create?

[ysimonson]

That error is happening because you’re not passing a valid UUID (as a 16-byte array of bytes) for the id. I’m not sure about the rest, it looks like the gRPC implementation you’re using is doing something weird, giving back some low level details rather than the properly deserialized response.

@ysimonson
Thanks for feedback. But when I send proper 16-byte uuid, in most of cases it returns the following format (empty array)
#229 (comment)
As I think it should return true/false inside 'array'.

[kination]

Not quite sure, but seems returning empty array is just happening that node indicates array with false as empty one.
So I think this issue is okay.

But for the future, it will be good if returning data includes detail log 🤔
