Read rows from Oracle table

Used integrations:
class OracleSourceSelect {
async init() {
// TODO: Create your oracle credential
// More info at https://yepcode.io/docs/integrations/oracle/#credential-configuration
const oraclePool = await yepcode.integration.oracle(
"your-oracle-credential-name"
);
this.connection = await oraclePool.getConnection();
}

async fetch(publish, done) {
const stream = this.connection
// TODO: Customize your sql query
.queryStream(`SELECT * FROM your_table_name`);
stream.on("data", async (row) => {
// TODO: map your row to an item
const item = {
...row
};

await publish(item);
});
stream.on("error", (error) => {
throw error;
});
stream.on("end", () => stream.destroy());
stream.on("close", done);
}

async close() {
await this.connection.close();
}
}

Send RabbitMQ messages

Used integrations:
class AmqpTargetRabbitmqSendMessage {
async init() {
// TODO: Create your rabbitmq credential
// More info at https://yepcode.io/docs/integrations/amqp/#credential-configuration
this.conn = await yepcode.integration.amqp("your-amqp-credential-name");
this.channel = await this.conn.createChannel();
}

async consume(item) {
// TODO: Customize your queue name and message
const queue = "tasks";
const message = `The message content is: ${JSON.stringify(item)}`;
this.channel.sendToQueue(queue, Buffer.from(message));
}

async close() {
try {
await this.channel.close();
} catch (error) {
console.error(`Error closing channel`, error);
}
try {
await this.conn.close();
} catch (error) {
console.error(`Error closing connection`, error);
}
}
}

YepCode is a SaaS platform that enables the creation, execution and monitoring of 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 or Python.

These recipes are an excellent starting point for creating your own YepCode processes and solving complex integration and automation problems.

You only have to complete 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 focus, offering a multi-tenant environment, team management capabilities, high security and auditing standards, Identity Provider (IdP) integrations, and on-premise options. It serves as the Swiss army knife for engineering teams, especially those requiring the extraction or transmission of information to external systems. It excels in scenarios demanding flexibility and adaptability to change within the process.

Sure! You only need to configure YepCode servers to establish a connection with that service. Check our docs page to get more information.
