Details#

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger#

New Row on MySQL

Description:Emit new event when you add a new row to a table. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/select.html)

Version:2.0.3

MySQL Overview#

The MySQL application on Pipedream enables direct interaction with your MySQL databases, allowing you to perform CRUD operations—create, read, update, delete—on your data with ease. You can leverage these capabilities to automate data synchronization, report generation, and event-based triggers that kick off workflows in other apps. With Pipedream's serverless platform, you can connect MySQL to hundreds of other services without managing infrastructure, crafting complex code, or handling authentication.

Trigger Code#

import common from "../common/table.mjs";

const { mysql } = common.props;

export default {
  ...common,
  key: "mysql-new-row",
  name: "New Row",
  description: "Emit new event when you add a new row to a table. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/select.html)",

    },
  },

    /**
     * If column prop is left blank, get the table's primary key to use for ordering and deduping.
     * */
    async deploy() {
      const { table } = this;
      let column = this.column;

      if (!column) {

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
MySQL	`mysql`	`app`	This component uses the MySQL app.
	`timer`	`$.interface.timer`
Table	`table`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Column	`column`	`string`	Select a value from the drop down menu.

Trigger Authentication#

MySQL uses API keys for authentication. When you connect your MySQL account, Pipedream securely stores the keys so you can easily authenticate to MySQL APIs in both code and no-code steps.

Before you connect to your MySQL database from Pipedream, please make sure your database is either:

Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 3306), or
Accessible from a static IP that you've configured using a VPC in Pipedream, and enabled the workflow to connect through that VPC

SSL Setup

Configure SSL on your MySQL database by providing the CA (Certificate Authority), and choosing between Full Verification, Verify Certificate Authority (CA), or Skip Verification. Skipping verification is not recommended as this has serious security implications.

About MySQL#

MySQL is an open-source relational database management system.

Scrape-It.Cloud Overview#

The Scrape-It.Cloud API allows you to automate the extraction of data from websites. It can parse, scrape, and retrieve content without the need for manual intervention. With this API on Pipedream, you can build workflows that trigger on various events and use the scraped data for numerous applications like data analysis, lead generation, and content aggregation.
