Twitch Overview#

The Twitch API unlocks a world of possibilities for engaging with live streaming communities and understanding audience behaviors. With Pipedream, you can harness this API to automate many aspects of Twitch interaction and analysis. From tracking stream stats to automating chat messages, the Twitch API lets you create workflows that interact with Twitch's vast live streaming ecosystem. Pipedream's serverless platform streamlines these tasks, making it simple to connect Twitch with other services for enhanced functionalities.

Trigger Code#

import common from "../common-polling.mjs";

export default {
  ...common,
  name: "New Followed Streams",
  key: "twitch-followed-streams",
  description: "Emit new event when a followed stream is live.",
  version: "0.1.2",

        id, started_at: startedAt,
        title: summary,
      } = item;
      const ts = new Date(startedAt).getTime();

      const { data: authenticatedUserData } = await this.twitch.getUsers();
      this.db.set("authenticatedUserId", authenticatedUserData[0].id);
    },
  },
  async run() {
    const params = {

      this.twitch.getUserFollows.bind(this),
      params,

    const followedIds = [];
    for await (const follow of follows) {
      followedIds.push(follow.to_id);
    }

    });
    for await (const stream of streams) {
      this.$emit(stream, this.getMeta(stream));
    }
  },
};

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
Twitch	`twitch`	`app`	This component uses the Twitch app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
	`timer`	`$.interface.timer`

Trigger Authentication#

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

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

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.

Action Code#

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

export default {
  key: "mysql-delete-row",
  name: "Delete Row",
  description: "Delete an existing row. [See the docs here](https://dev.mysql.com/doc/refman/8.0/en/delete.html)",
  type: "action",
  version: "2.0.5",
  props: {
    mysql,
    table: {
      description: "The table to delete a row from",
      propDefinition: [
        mysql,
        "table",
      ],
    },
    condition: {
      propDefinition: [
        mysql,
        "whereCondition",
      ],
    },
    values: {
      propDefinition: [
        mysql,
        "whereValues",
      ],
    },
  },
  async run({ $ }) {
    const {
      table,
      condition,
      values,
    } = this;

    const numberOfQuestionMarks = condition?.match(/\?/g)?.length;

    if (!numberOfQuestionMarks) {
      throw new Error("No valid condition provided. At least one question mark character ? must be provided.");
    }

    if (!Array.isArray(values)) {
      throw new Error("No valid values provided. The values property must be an array.");
    }

    if (values.length !== numberOfQuestionMarks) {
      throw new Error("The number of values provided does not match the number of question marks ? in the condition.");
    }

    const result = await this.mysql.deleteRows({
      table,
      condition,
      values,
    });

    $.export("$summary", `Successfully deleted ${result.affectedRows} row(s) from table ${table}`);

    return result;
  },
};

Action Configuration#

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

Label	Prop	Type	Description
MySQL	`mysql`	`app`	This component uses the MySQL app.
Table	`table`	`string`	Select a value from the drop down menu.
Where condition	`condition`	`string`	In this expression you can write your own conditions (eg. `column1 = ? or column2 = ?`). Depending on the number of `?` symbols likewise you need to add the same number of values.
Values	`values`	`string[]`	This is the list of values that will match every `?` symbol in the where expression. If you want to build yourself the values (eg. `{{["string1", "string2"]}}`)

Action 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.
