Read CSV file entries from Azure Blob container

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

async fetch(publish, done) {
// TODO: customize the container name and blob name to download
// // More info at https://docs.microsoft.com/en-us/javascript/api/@azure/storage-blob/blobserviceclient?view=azure-node-latest#@azure-storage-blob-blobserviceclient-getcontainerclient
const containerClient = this.azureBlob.getContainerClient("container-name");
const blobClient = containerClient.getBlobClient("blob-name");
const result = await blobClient.download();

// result.readableStreamBody is a stream of object content
result.readableStreamBody
.pipe(
csv.parse({
delimiter: ",",
columns: true,
})
)
.on("data", publish)
.on("end", done);
}

async close() {}
}

async init() {
// TODO: Create your kafka credential
// More info at https://yepcode.io/docs/integrations/kafka/#credential-configuration
const kafka = yepcode.integration.kafka("your-kafka-credential-name");
this.producer = kafka.producer();
await this.producer.connect();
}

async consume(item) {
// TODO: customize your message and topic
const message = `Your message content ${item.name}`;

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.
