Documentation: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-dynamodb/index.html NPM: https://www.npmjs.com/package/@aws-sdk/client-dynamodb Source Code: https://github.com/aws/aws-sdk-js-v3/tree/main/clients/client-dynamodb

Getting started

1. Create a Javascript Dynamodb client in /less/shared/dynamodb_client_js/index.js.

   const { 
     DynamoDBClient,
     ListTablesCommand
   } = require('@aws-sdk/client-dynamodb');
   
   const { AMAZON_ACCESS_KEY_ID, AMAZON_SECRET_ACCESS_KEY } = process.env;
   
   const client = new DynamoDBClient({
     credentials: {
       accessKeyId: AMAZON_ACCESS_KEY_ID,
       secretAccessKey: AMAZON_SECRET_ACCESS_KEY
     }
   });
   
   const list_tables = () => {
     const command = new ListTablesCommand({});
     const response = await client.send(command);
     return response;
   };

2. Create a GET /hello/js route in /less/apis/demo/hello/js/get.js to test.

   const { list_tables } = require('dynamodb_client_js');
   
   module.exports = {
     process: async (request, response) => {
       // Fetch all tables.
       const result = await list_tables();
   
       // Return HTTP response.
       response.statusCode = 200;
       response.body = JSON.stringify(result);
       return response;
     }
   };

3. Deploy!

   npx @chuva.io/less-cli deploy YOUR_PROJECT_NAME
