Read NDJSON file entries from Azure Blob container

Used integrations:
class AzureBlobSourceReadRemoteNdjson {
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(ndjson.parse())
.on("data", async (line) => {
await publish(line);
})
.on("end", done);
}

async close() {}
}

FAQs

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 or Python.

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

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.
