Connect Keycloak users and Google Storage NDJSON file in our serverless environment

Use this template to Find Keycloak users using them to create NDJSON file entries in Google Storage Bucket.


Find Keycloak users

Used integrations:
class KeycloakSourceFindUsers {
async init() {
// TODO: Create your keycloak credential
// More info at
this.keycloakClient = await yepcode.integration.keycloak(

async fetch(publish, done) {
// TODO: Customize your find users payload
// See possible options at:
const users = await this.keycloakClient.users.find({
email: "yep",
exact: false, // An example to search users with email containing "yep"
max: 100,

// Each user is an object with content following the structure you can find at:
for (const user of users) {
await publish(user);

async close() {}

Create NDJSON file entries in Google Storage Bucket

Used integrations:
class GoogleStorageTargetUploadNdjson {
async init() {
// TODO: Create your google-storage credential
// More info at
const googleStorage = yepcode.integration.googleStorage(
// TODO: Customize your bucket name
const bucket = googleStorage.bucket("your-bucket-name");
// TODO: choose a destination file
const blob = bucket.file(`one-folder/my-filename-${}.ndjson`);
const ws = blob.createWriteStream({
metadata: {
contentType: "text/ndjson",

// Transforms the items into a ndjson format
this.stringifier = ndjson.stringify();

async consume(item) {

async close() {

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.
