Read items from AWS DynamoDB table

Used integrations:
class AwsDynamodbSourceScan {
async init() {
// TODO: Create your aws-dynamodb credential
// More info at https://yepcode.io/docs/integrations/aws-dynamodb/#credential-configuration
this.awsDynamodb = yepcode.integration.awsDynamodb(
"your-aws-dynamodb-credential-name"
);
}

async fetch(publish, done) {
// TODO: Customize the scan command
// More info at: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-dynamodb/interfaces/scancommandinput.html
const scanCommand = new ScanCommand({
TableName: "table-name"
});

const result = await this.awsDynamodb.send(scanCommand);

for (const item of result.Items) {
await publish(item);
}

done();
}

async close() {}
}

Used integrations:
class NodemailerTargetSendEmail {
async init() {
// TODO: Create your nodemailer credential
// More info at https://yepcode.io/docs/integrations/nodemailer/#credential-configuration
this.nodemailer = yepcode.integration.nodemailer(
"your-nodemailer-credential-name"

this.items = [];
}

async consume(item) {
// we save the items for later
this.items.push(item);
// we could send a mail per item here if we want to
}

async close() {

These recipes are a good starting point for you to build your own YepCode processes and solve your integration and automation problems.

YepCode is a SaaS platform that allows to create, execute and monitor integrations and automations using source code in a serverless environment.

We like to call it the Zapier for developers, since we bring all the agility and benefits of NoCode tools (avoid server provisioning, environment configuration, deployments,...), but with all the power of being able to use a programming language like JavaScript with a NodeJS engine.

You only have to fill the sign up form and your account will be created with our FREE plan (no credit card required).

YepCode has been created with a clear enterprise approach (multi-tenant environment, team management, high security and auditing standards, IdP integrations, on-premise options,...) so we can be the Swiss army knife of any team of engineering, especially those that need to extract or send information to external systems, and where a certain dynamism or adaptation to change is necessary in that process.

Sure! You just need to do some configuration to allow YepCode servers to connect to that service. Check our docs page to get more information.

Ask us for help to solve your integration problem

Recipes may be used in a self service approach cloning them to one YepCode account, but if you are looking for a turnkey approach, our team may help you.
