Connect PostgreSQL and Send email in our serverless environment

Use this template to Read rows from PostgreSQL table using them to send email messages.


Read rows from PostgreSQL table

Used integrations:
class PostgresSourceSelect {
async init() {
// TODO: Create your postgres credential
// More info at
this.postgresPool = yepcode.integration.postgres(

async fetch(publish, done) {
// TODO: Customize your sql query
const {
} = await this.postgresPool.query(
"SELECT * FROM your_schema.your_table LIMIT 10"
for (const row of rows) {
await publish(row);

async close() {
await this.postgresPool.end();

Send email messages

Used integrations:
class SmtpTargetSendEmail {
async init() {
// TODO: Create your smtp credential
// More info at
this.nodemailer = yepcode.integration.smtp("your-smtp-credential-name");
this.items = [];

async consume(item) {
// we save the items for later
// we could send a mail per item here if we want to

async close() {
// we want to send a resume mail so we send it at the end
// TODO: Customize email content
const text = `Here are the items we got:
${ => ` * ${}: ${}`).join("\n")}`;

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.
