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.

MySQL Overview#

MySQL is a powerful database management system used by some of the largest
organizations in the world, including Facebook, Google, and Amazon. MySQL is an
open-source relational database management system (RDBMS), as well as a popular
choice for web applications used by millions of websites.

Some applications that can be built using the MySQL API include:

A web application that stores and retrieves data from a MySQL database
A desktop application that uses a MySQL database for data storage
A mobile application that interacts with a MySQL database

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: "0.0.5",
  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() {
      let previousColumns = this._getPreviousColumns() || [];
      const columns = await this.mysql.listNewColumns(
        this.table,
        previousColumns,
        this.rejectUnauthorized,
      );
      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`	`$.interface.timer`
Reject Unauthorized	`rejectUnauthorized`	`boolean`	If not false, the server certificate is verified against the list of supplied CAs. If you get an error about SSL try to set this prop as `false`
Table	`table`	`string`	Select a value from the drop down menu.
N/A	`db`	`$.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.

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 an SSH server that you route MySQL requests through

After that, enter the following values:

host: The hostname or IP address of your MySQL server
port: 3306, unless you run MySQL on a different port
username: The account username to log in
password: The account password to log in
database: The name of the MySQL database to run queries against

Slack Overview#

The Pipedream Slack app enables you to build event-driven workflows that interact with the Slack API. When you authorize the Pipedream app's access to your workspace, you can use Pipedream workflows to perform common Slack actions, or write your own code against the Slack API.

The Pipedream Slack app is not a typical app. You don't interact with it directly as a bot, and it doesn't add custom functionality to your workspace out of the box. It just makes it easier to automate anything you'd typically use the Slack API for, using Pipedream workflows.

Here are some examples of automations you can build with Pipedream on Slack:

Automate posting updates to your team channel
Create a bot to answer common questions
Integrate with your existing tools and services
Build a custom dashboard to track your team's progress
Create a bot to handle scheduling and meeting requests
And much more!

Should I use the Slack or Slack Bot app on Pipedream?

The Slack app is the easiest and most convienent option to get started. It installs the official Pipedream bot into your Slack workspace with just a few clicks.

However, if you'd like to use your own bot registered with the Slack API, you can use the Slack Bot app instead.

The Slack Bot requires a bot token to allow your Pipedream workflows to authenticate as your bot. The extra set up steps allow you to list your custom bot on the Slack Marketplace, or install the bot on other workspaces as your bot's name instead of as Pipedream.

Getting Started

You can install the Pipedream Slack app in the Accounts section of your account, or directly in a workflow

Accounts

Visit https://pipedream.com/accounts.
Click on the Click Here To Connect An App button in the top-right.
Search for "Slack" among the list of apps, and select it.
This will open a new window asking you to allow Pipedream access to your Slack workspace. Choose the right workspace where you'd like to install the app, then click Allow.
That's it! You can now use this Slack account in any actions, or link it to any code step.

Within a workflow

Create a new workflow.
Select your trigger (HTTP, Cron, etc.).
Click on the + button below the trigger step, and search for "Slack".
Select the Send a Message action.
Click the Connect Account button near the top of the step. This will prompt you to select any existing Slack accounts you've previously authenticated with Pipedream, or you can select a New account. Clicking New opens a new window asking you to allow Pipedream access to your Slack workspace. Choose the right workspace where you'd like to install the app, then click Allow.
That's it! You can now connect to the Slack API using any of the Slack actions within a Pipedream workflow.

Label	Prop	Type	Description
Slack	`slack`	`app`	This component uses the Slack app.
Send as User	`as_user`	`boolean`	Optionally pass `TRUE` to post the message as the authed user, instead of as a bot. Defaults to `FALSE`.
Bot Username	`username`	`string`	Optionally customize your bot's username (default is `Pipedream`).

Include link to workflow	`include_sent_via_pipedream_flag`	`boolean`	Defaults to `true`, includes a link to the workflow at the end of your Slack message.
Metadata Event Type	`metadata_event_type`	`string`	The name of the metadata event
Metadata Event Payload	`metadata_event_payload`	`string`	The payload of the metadata event. Must be a JSON string e.g. `{"key": "value"}`

Action Authentication#

Slack uses OAuth authentication. When you connect your Slack account, Pipedream will open a popup window where you can sign into Slack and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Slack API.

Pipedream requests the following authorization scopes when you connect your account:

bookmarks:writecalls:readcalls:writechannels:historychannels:readchannels:writednd:readdnd:writeemoji:readfiles:readgroups:historygroups:readgroups:writeim:historyim:readim:writelinks:readlinks:writempim:historympim:readmpim:writepins:readpins:writereactions:readreactions:writereminders:readreminders:writeremote_files:readremote_files:sharestars:readstars:writeteam:readusergroups:readusergroups:writeusers:readusers:read.emailusers:writechat:write:botchat:write:usercommandsfiles:write:userusers.profile:writeusers.profile:readsearch:read
