DynamoDB: Get All Items (Guide w/ Code Examples)

To retrieve all items from a DynamoDB table using the JavaScript SDK, you can use the scanmethod. The scan method retrieves all items from the table. So it should be used with caution on large tables. Also, you can use the scan method with filterExpression to filter the items you want.

const AWS = require("aws-sdk");
const dynamoDB = new AWS.DynamoDB();

const params = {
    TableName: "myTable"
};

dynamoDB.scan(params, (err, data) => {
    if (err) {
        console.error("Unable to scan the table. Error JSON:", JSON.stringify(err, null, 2));
    } else {
        console.log("Scan succeeded.");
        data.Items.forEach((item) => {
            console.log("Item :", JSON.stringify(item));
        });
    }
});
