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.

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.

Label	Prop	Type	Description
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling Interval	`timer`	`$.interface.timer`	Pipedream will poll the API on this schedule
Reject Unauthorized	`rejectUnauthorized`	`boolean`	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`
Schema	`schema`	`string`	Select a value from the drop down menu.
Table	`table`	`string`	Select 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:

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 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#

Send Message on Discord

Description:Send a simple message to a Discord channel

Version:1.0.1

Key:discord-send-message

View on GitHub

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.

Label	Prop	Type	Description
Discord	`discord`	`app`	This component uses the Discord app.
channel	`channel`	`$.discord.channel`
Message	`message`	`string`	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 ID	`threadID`	`string`	If provided, the message will be posted to this thread
Username	`username`	`string`	Overrides the current username of the webhook
Avatar URL	`avatarURL`	`string`	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 workflow	`includeSentViaPipedream`	`boolean`	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:
