Read CSV entries from a remote file

Used integrations:
class HttpSourceReadRemoteCsv {
async init() {
// TODO: Create your http credential with endpoint information:
// More info at https://yepcode.io/docs/integrations/http/#credential-configuration
// It may manage headers or authentication
this.httpClient = yepcode.integration.http("your-http-credential-name");
}

async fetch(publish, done) {
// TODO: Customize the path to the csv file
await this.httpClient
.get("/the-csv-file-path.csv", {
responseType: "stream",
})
.then(({
data
}) => {
data
.pipe(
csv.parse({
trim: true,
columns: true,
delimiter: ",",
skip_empty_lines: true,
})
)
.on("data", async (line) => {
// TODO: Map your item
const item = {
id: line.Index,
name: line.Name
};
await publish(item);
})
.on("end", done);
});
}

async close() {}

Create NDJSON file entries in Amazon S3 Bucket

Used integrations:
class AwsS3TargetUploadNdjson {
async init() {
// TODO: Create your aws-s3 credential
// More info at https://yepcode.io/docs/integrations/aws-s3/#credential-configuration
const awsS3 = yepcode.integration.awsS3("your-aws-s3-credential-name");
// Transforms the items into a ndjson format
this.stringifier = ndjson.stringify();
const targetStream = new PassThrough();
this.stringifier.pipe(targetStream);
// TODO: customize the Upload content
// More info at: https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/interfaces/_aws_sdk_lib_storage.options-1.html
const upload = new Upload({
client: awsS3,
params: {
Bucket: "your-bucket-name",
Key: "your-file-name.ndjson",
Body: targetStream,
},
});
upload.on("httpUploadProgress", (progress) => {
console.log(`Upload progress`, progress);
});
this.uploadPromise = upload.done();
}

async consume(item) {
this.stringifier.write(item);
}

async close() {

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.
