Reddit Overview#

The Reddit API unlocks the potential to automate interactions with one of the largest online communities. With Pipedream, you can tap into the Reddit ecosystem to monitor trends, engage with audiences, or curate content. Whether it's tracking mentions of your brand, auto-posting to subreddits, or gathering data for analysis, the API offers a breadth of functionalities — from getting posts and comments to creating new threads and managing account settings.

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
Reddit	`reddit`	`app`	This component uses the Reddit app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling schedule	`timer`	`$.interface.timer`	Pipedream polls Reddit for events on this schedule.
Subreddit	`subreddit`	`string`	Select a value from the drop down menu.
Post	`subredditPost`	`string`	Select a value from the drop down menu.
numberOfParents	`numberOfParents`	`integer`	When set to 0, the emitted events will only contain the new comment. Otherwise, the events will also contain the parents of the new comment up to the number indicated in this property.
Depth	`depth`	`integer`	If set to `1`, it will include, in the emitted event, only new comments that are direct children to the subreddit pointed by "subredditPost". Furthermore, "depth" determines the maximum depth of children, within the related subreddit comment tree, of new comments to be included in said emitted event.
Include subreddit details?	`includeSubredditDetails`	`boolean`	If set to `true`, subreddit details will be expanded/included.

Trigger Authentication#

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

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

MongoDB Overview#

The MongoDB API provides powerful capabilities to interact with a MongoDB database, allowing you to perform CRUD (Create, Read, Update, Delete) operations, manage databases, and execute sophisticated queries. With Pipedream, you can harness these abilities to automate tasks, sync data across various apps, and react to events in real-time. It’s a combo that’s particularly potent for managing data workflows, syncing application states, or triggering actions based on changes to your data.

Action Code#

import mongodbApp from "../../mongodb.app.mjs";

export default {
  key: "mongodb-find-document-by-id",
  name: "Find Document by Id",
  description: "Retrieves a single document by ID. [See the docs here](https://docs.mongodb.com/manual/reference/method/db.collection.find/)",
  version: "0.1.5",
  type: "action",
  props: {
    mongodbApp,
    database: {
      propDefinition: [
        mongodbApp,
        "database",
      ],
    },
    collection: {
      propDefinition: [
        mongodbApp,
        "collection",
        (c) => ({
          database: c.database,
        }),
      ],
    },
    document: {
      propDefinition: [
        mongodbApp,
        "document",
        (c) => ({
          database: c.database,
          collection: c.collection,
        }),
      ],
    },
  },
  async run({ $ }) {
    const document = await this.mongodbApp.findDocumentById(
      this.database,
      this.collection,
      this.document,
    );

    $.export("$summary", this.document
      ? `Document "${this.document}" successfully fetched`
      : "No document found");
    return document;
  },
};

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
MongoDB	`mongodbApp`	`app`	This component uses the MongoDB app.
Database	`database`	`string`	Select a value from the drop down menu.
Collection	`collection`	`string`	Select a value from the drop down menu.
Document	`document`	`string`	Select a value from the drop down menu.

Action Authentication#

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

Before you connect to your Mongo database from Pipedream, please make sure your database is accessible from the public internet. You may need to add a firewall rule allowing connections from 0.0.0.0/0.

Then, enter the details of your Mongo host / database below.
