CRUD operations using DynamoDB with expressjs (node js)

Question

I am trying to create a route which will perform some CRUD operations on DynamoDB. At high level , it can be understood as :

1. The node js server application is running .(i.e. command 'node server.js' is being triggered)
2. The user uses POSTMAN of chrome browser to do route requests.
3. The user does a GET request for 'http://localhost:8080/listtablesofdynamodb'.
4. The specific route connected with this url gets hit which should do dynamodb specific activity. (like connecting to dynamodb ,fetching table names and showing it in callback method.)

the reason I am asking this question is because I could not find any relevant tutorial of how to do dynamodb activity by using express js of node. All I could find is console applications on aws website which seems not useful for me. Any kind of help is highly appreciated.

Answer 1

Access key required

All you need to d is make a DynamoDB object to connect too

var ddb = require('dynamodb').ddb({ accessKeyId: '< your_access_key_id >', secretAccessKey: '< your_secret_access_key >' });

put this under your require statements, turn on your server. Then you can just fill out the routes to do the CRUD operations you need.

To test it use

ddb.listTables({}, function(err, res) {console.log(res);});

This will list all the tables in your db.
