How to search OpenSearch DB with nodejs lambda function ?

[ouelletalexandre]

Hello,

I have a nodejs lambda function that have to search into an opensearch DB. I want to use the aws-sdk-v3. I have found the doc here for OpenSearchClient:

https://github.com/aws/aws-sdk-js-v3/tree/246d6534c53dcf9bd2eb6a620cb5b6c04b27451a/clients/client-opensearch

But as you see, there is almost nothing explained there. For example, I have to create a AcceptInboundConnectionCommand with "params", but there are no explanations what are the properties required for this "params" object.

When I search "AcceptInboundConnectionCommand" on google, there is only 3 results... Is this SDK usable ? Or is still a prototype or something ?

Hi @ouelletalexandre ,

The SDK is usable 😄
Here is the link to the docs that you'll need to figure out which shapes the commands take in.

As a rule of thumb, every command in the SDK for example: getSomethingCommand will take a JS object of type getSomethingCommandInput as input, and return a JS object as output in the same convention getSomethingCommandOutput

So in your caseAcceptInboundConnectionCommand will take in a AcceptInboundConnectionCommandInput type. In this it takes in an object with this property:

so your code will look something like this:

import { OpenSearchClient, AcceptInboundConnectionCommand } from "@aws-sdk/client-opensearch";

const client = new OpenSearchClient({ region: 'us-east-1' });


 // to find what params we need you'll go to the docs and look for AcceptInboundConnectionCommandInput
const input = {
  ConnectionId: myConnectionID
};

const command = new AcceptInboundConnectionCommand(input);

try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  // error handling.
}

Let me know if that helps.
Thanks,
Ran~

Hello !

I realized that I was wrong by using this client, I thought I could use it to search for data in the OpenSearch DB. Eventually I found that I should use this instead : https://docs.aws.amazon.com/opensearch-service/latest/developerguide/request-signing.html#request-signing-node

Thanks !
