dynamodb node aws-sdk simple getItem() call

Question

Folks, New to Javascript... trying to do simple dynamo queries from node:

var AWS = require(\'aws-sdk\');
AWS.config.update({region: \'us-east-1\'});
var db = ne         


        

Answer 1

I was trying to do it as it was suggested in the documentation, but also got errors.

At the end the following worked:

var aws = require('aws-sdk');
var db = new aws.DynamoDB({
  region: 'eu-central-1',
  maxRetries: 1
});

exports.handler = event => {
    return queryMyThings();
}

const queryMyThings = async (event) => { 
 var params = {
      Key: {
      "ColumnByWhichYouSearch": {
         S: "ValueThatYouAreQueriing"
        }
      }, 
      TableName: "YourTableName"
     };

    return await db.getItem(params).promise();

}
