Getting Started#

This integration creates a workflow with a MySQL trigger and QStash action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Column trigger
1. Connect your MySQL account
2. Configure timer
3. Select a Table
Configure the Create Endpoint action
1. Connect your QStash account
2. Select a QStash Topic
3. Configure Endpoint URL

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#

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";

export default {
  ...common,
  key: "mysql-new-column",
  name: "New Column",
  description: "Emit new event when you add a new column to a table. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/show-columns.html)",
  type: "source",
  version: "2.0.5",
  dedupe: "unique",
  props: {
    ...common.props,
    db: "$.service.db",
  },
  methods: {
    ...common.methods,
    _getPreviousColumns() {
      return this.db.get("previousColumns");
    },
    _setPreviousColumns(previousColumns) {
      this.db.set("previousColumns", previousColumns);
    },
    async listResults() {
      const { table } = this;
      let previousColumns = this._getPreviousColumns() || [];
      const columns = await this.mysql.listNewColumns({
        table,
        previousColumns,
      });
      this.iterateAndEmitEvents(columns);

      const newColumnNames =
        columns
          .map((column) => column.Field)
          .filter((c) => !previousColumns.includes(c));

      previousColumns = previousColumns.concat(newColumnNames);
      this._setPreviousColumns(previousColumns);
    },
    generateMeta(column) {
      const columnName = column.Field;
      return {
        id: `${columnName}${this.table}`,
        summary: columnName,
        ts: Date.now(),
      };
    },
  },
};

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.

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.

Connecting to Restricted Databases

Either enable the shared static IP for this account below, or configure a VPC to deploy any workflow in your workspace to a private network with a dedicated static IP. Learn more in our docs.

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.

QStash Overview#

QStash API offers a secure, scalable, and simple way to manage message queues and defer tasks. Using this API, you can enqueue messages, schedule tasks to run after a delay, and ensure that tasks are executed exactly once, leveraging the power of serverless architecture. With Pipedream's ability to connect to a multitude of services, you can build complex workflows that trigger actions in other apps based on events in QStash, allowing you to automate cross-application business processes with ease.

Action Code#

import qstash from "../../qstash.app.mjs";

export default {
  name: "Create Endpoint",
  version: "0.0.1",
  key: "qstash-create-endpoint",
  description: "Create a new HTTP endpoint on a QStash topic.",
  props: {
    qstash,
    topicId: {
      type: "string",
      label: "QStash Topic",
      description: "The QStash topic to subscribe to.",
      async options() {
        const topics = await this.qstash.listTopics({
          $: this,
        });

        return topics.map((topic) => ({
          label: topic.name,
          value: topic.topicId,
        }));
      },
    },
    endpointUrl: {
      propDefinition: [
        qstash,
        "endpointUrl",
      ],
    },
  },

  async run({ $ }) {
    const {
      topicId, topicName, endpointUrl,
    } = this;
    return this.qstash.createEndpoint({
      $,
      topicId,
      topicName,
      endpointUrl,
    });
  },
};
