Details

This integration uses pre-built, open source 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

Description:Emit new event when a new column is added to a table. [See Docs](https://node-postgres.com/features/queries)
Version:0.0.5
Key:postgresql-new-column

PostgreSQL Overview

Assuming you want a few paragraphs on what you can do with the PostgreSQL API:

The following examples demonstrate some of the things that can be done with the
PostgreSQL API:

  • Developing a custom storage engine for PostgreSQL
  • Adding a new data type to PostgreSQL
  • Creating a new function for PostgreSQL
  • Building a graphical user interface for PostgreSQL
  • And much more!

Trigger Code

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

export default {
  ...common,
  name: "New Column",
  key: "postgresql-new-column",
  description: "Emit new event when a new column is added to a table. [See Docs](https://node-postgres.com/features/queries)",
  version: "0.0.5",
  type: "source",
  props: {
    ...common.props,
    schema: {
      propDefinition: [
        common.props.postgresql,
        "schema",
      ],
    },
    table: {
      propDefinition: [
        common.props.postgresql,
        "table",
        (c) => ({
          schema: c.schema,
        }),
      ],
    },
  },
  async run() {
    const previousColumns = this._getPreviousValues() || [];

    const columns = await this.postgresql.getColumns(this.table, this.schema);

    const newColumns = columns.filter((column) => !previousColumns.includes(column));
    for (const column of newColumns) {
      const meta = this.generateMeta(column);
      this.$emit(column, meta);
    }

    this._setPreviousValues(columns);
  },
};

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.

Pipedream will poll the API on this schedule

Reject UnauthorizedrejectUnauthorizedboolean

If not false, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails

Trigger Authentication

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

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

  1. Accessible from the public internet (You may need to add a firewall rule on 0.0.0.0/0 on port 3306), or

  2. Accessible from an SSH server that you route PostgreSQL requests through

After that, enter the following values:

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

Action

Description:Send a simple or structured message (using embeds) to a Discord channel
Version:0.3.1
Key:discord_webhook-send-message-advanced

Discord Webhook Overview

With Discord's Webhook API, you can create applications that send messages to
Discord channels automatically. For example, you could create a bot that sends
a message to a channel every time a new blog post is published, or a message to
a channel when someone joins your Discord server.

Here are some ideas for what you could build using the Discord Webhook API:

  • A bot that sends a message to a channel when a new blog post is published
  • A bot that sends a message to a channel when someone joins your Discord
    server
  • A bot that sends a message to a channel when a new product is added to your
    online store

Action Code

import common from "../send-message-common.mjs";

export default {
  ...common,
  key: "discord_webhook-send-message-advanced",
  name: "Send Message (Advanced)",
  description: "Send a simple or structured message (using embeds) to a Discord channel",
  version: "0.3.1",
  type: "action",
  props: {
    ...common.props,
    message: {
      propDefinition: [
        common.props.discordWebhook,
        "message",
      ],
      optional: true,
    },
    embeds: {
      propDefinition: [
        common.props.discordWebhook,
        "embeds",
      ],
    },
  },
  async run({ $ }) {
    const {
      message,
      avatarURL,
      threadID,
      username,
      includeSentViaPipedream,
      embeds,
    } = this;

    if (!message && !embeds) {
      throw new Error("This action requires at least 1 message OR embeds object. Please enter one or the other above.");
    }

    try {
      // No interesting data is returned from Discord
      await this.discordWebhook.sendMessage({
        avatarURL,
        threadID,
        username,
        embeds,
        content: includeSentViaPipedream
          ? this.appendPipedreamText(message ?? "")
          : message,
      });
      $.export("$summary", "Message sent successfully");
    } catch (err) {
      const unsentMessage = this.getUserInputProps();
      $.export("unsent", unsentMessage);
      throw err;
    }
  },
};

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.

LabelPropTypeDescription
Discord WebhookdiscordWebhookappThis component uses the Discord Webhook app.
Messagemessagestring

Enter a simple message up to 2000 characters. This is the most commonly used field. However, it's optional if you pass embed content.

Thread IDthreadIDstring

If provided, the message will be posted to this thread

Usernameusernamestring

Overrides the current username of the webhook

Avatar URLavatarURLstring

If used, it overrides the default avatar of the webhook. Note: Consecutive posts by the same username within 10 minutes of each other will not display updated avatar.

Include link to workflowincludeSentViaPipedreamboolean

Defaults to true, includes a link to this workflow at the end of your Discord message.

Embedsembedsany

Optionally pass an array of embed objects. E.g., {{ [{"description":"Use markdown including *Italic* **bold** __underline__ ~~strikeout~~ [hyperlink](https://google.com) `code`"}] }}. To pass data from another step, enter a reference using double curly brackets (e.g., {{steps.mydata.$return_value}}).
Tip: Construct the embeds array in a Node.js code step, return it, and then pass the return value to this step.

Action Authentication

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

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

webhook.incomingemailidentify
