aws-sdk : DynamoDB : Fetch list of all tables

Question

I am using aws-sdk for nodejs in a project, and not finding any way to fetch all tables from an endpoint, in other words I am looking forward for equivalent of following command in SDK.

aws dynamodb list-tables --endpoint-url <ENDPOINT_URL>

Any help is much appreciated.

Regards.

If you have more than 100 tables, then you also need to be aware of pagination. You can use this example for Node.js:

const readAllTables = async() => {
  const AWS = require("aws-sdk");
  var dynamodb = new AWS.DynamoDB();

  var params = {};
  var tables = [];

  while(true) {
    var response = await dynamodb.listTables(params).promise();
    tables = tables.concat(response.TableNames);

    if (undefined === response.LastEvaluatedTableName) {
      break;
    } else {
      params.ExclusiveStartTableName = response.LastEvaluatedTableName;
    }
  }

  return tables;
}

Thanks friends, I found the solution as

 const AWS = require("aws-sdk");
 var dynamodb = new AWS.DynamoDB();
 var param = {}
    dynamodb.listTables(param, function (err, data) {
        if (err) console.log(err, err.stack); // an error occurred
        else     console.log(data);           // successful response
      });
