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

Description:Emit new event when a new column is added to a table. [See Docs](https://node-postgres.com/features/queries)
Version:0.0.7
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: "0.0.7",
  type: "source",
  props: {
    ...common.props,
    schema: {
      propDefinition: [
        common.props.postgresql,
        "schema",
        (c) => ({
          rejectUnauthorized: c.rejectUnauthorized,
        }),
      ],
    },
    table: {
      propDefinition: [
        common.props.postgresql,
        "table",
        (c) => ({
          schema: c.schema,
          rejectUnauthorized: c.rejectUnauthorized,
        }),
      ],
    },
  },
  async run() {
    const previousColumns = this._getPreviousValues() || [];

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

    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.
LabelPropTypeDescription
PostgreSQLpostgresqlappThis component uses the PostgreSQL app.
N/Adb$.service.dbThis component uses $.service.db to maintain state between executions.
Polling Intervaltimer$.interface.timer

Pipedream will poll the API on this schedule

Reject UnauthorizedrejectUnauthorizedboolean

If not false, the server certificate is verified against the list of supplied CAs. If you get the error Connection terminated unexpectedly try to set this prop as false

SchemaschemastringSelect a value from the drop down menu.
TabletablestringSelect a value from the drop down menu.

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 message to a Discord channel
Version:1.0.1
Key:discord-send-message

Discord Overview

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

Action Code

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

export default {
  ...common,
  key: "discord-send-message",
  name: "Send Message",
  description: "Send a simple message to a Discord channel",
  version: "1.0.1",
  type: "action",
  async run({ $ }) {
    const {
      message,
      avatarURL,
      threadID,
      username,
      includeSentViaPipedream,
    } = this;

    try {
      const resp = await this.discord.sendMessage(this.channel, {
        avatar_url: avatarURL,
        username,
        content: includeSentViaPipedream
          ? this.appendPipedreamText(message)
          : message,
      }, {
        thread_id: threadID,
      });
      $.export("$summary", "Message sent successfully");
      return resp || {
        success: true,
      };
    } catch (err) {
      console.log(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
DiscorddiscordappThis component uses the Discord app.
channelchannel$.discord.channel
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.

Action Authentication

Discord uses OAuth authentication. When you connect your Discord account, Pipedream will open a popup window where you can sign into Discord 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 API.

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