DynamoDB - create Table with nested document in javascript

Question

My question is similar to the one asked for java but need help with javascript aws-sdk. Couldn't find any examples.

the table structure would be as shown below:

customer:
  customerId: '12345'
  policies:
  - policyNumber: 12345
    status: active

You can try using DocumentClient.put() see documentation. Below is a sample from my existing code updated to match your payload but I haven't tested it since I didn't want to pollute my table.

   import AWS from 'aws-sdk';

   const params = {
      TableName: 'TBL_CUSTOMER', //or whatever your table name is
      Item: {
         customerId: '12345',
         policies: {
            policyNumber: 12345,
            status: 'active'
         }
      }
   };

   const documentClient = new AWS.DynamoDB.DocumentClient();

   const result = await new Promise((resolve, reject) => {
      documentClient.put(params, function (err, data) {
         if (err) reject(err);
         else resolve(data);
      });
   });
   console.log('result:', result);
