Getting Started#

This integration creates a workflow with a Discourse trigger and PostgreSQL action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

Select this integration
Configure the New Posts (Instant) trigger
1. Connect your Discourse account
2. Select one or more Categories
Configure the Execute SQL Query action
1. Connect your PostgreSQL account
2. Configure PostreSQL Query
Deploy the workflow
Send a test event to validate your setup
Turn on the trigger

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#

New Posts (Instant) on Discourse

Description:Emit new posts added to a topic in one of your chosen categories

Version:0.2.1

Key:discourse-new-posts-added

Discourse Overview#

The Discourse API empowers developers to interact programmatically with Discourse forums, allowing for a myriad of automations and integrations. Using Pipedream, you can harness this API for tasks such as syncing forum data with other platforms, automating user management, or triggering workflows based on forum activity. The key is in creatively coupling Discourse events with Pipedream's capabilities to streamline community interactions and administration.

Trigger Code#

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

export default {
  name: "New Posts (Instant)",
  key: "discourse-new-posts-added",
  version: "0.2.1",
  type: "source",
  description: "Emit new posts added to a topic in one of your chosen categories",
  ...common,
  props: {
    ...common.props,
    categories: {
      propDefinition: [
        discourse,
        "categories",
      ],
    },
  },
  hooks: {
    ...common.hooks,
    async deploy() {
      const latestPosts = await this.discourse.getLatestPosts(this.categories);
      for (const post of latestPosts) {
        this.$emit(post, this.generateMeta(post));
      }
    },
    async activate() {
      await this.activate({
        category_ids: this.categories,
        web_hook_event_type_ids: [
          "2",

      });
    },
  },

    ...common.methods,
    generateMeta(post) {
      const {
        id,
        raw,
        created_at: createdAt,
      } = post;
      const MAX_LENGTH = 40;
      return {
        id,
        summary:
          raw.length > MAX_LENGTH
            ? `${raw.slice(0, MAX_LENGTH)}...`
            : raw, // truncate long text
        ts: +new Date(createdAt),
      };
    },
  },
  async run(event) {
    this.validateEventAndEmit(event, "post_created", "post");
  },
};

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
N/A	`http`	`$.interface.http`	This component uses `$.interface.http` to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the `run()` method of the component.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Discourse	`discourse`	`app`	This component uses the Discourse app.
Categories	`categories`	`string[]`	Select a value from the drop down menu.

Trigger Authentication#

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

For domain, enter the hostname, without the protocol, that you'd use in this API call: https://[domain]/admin/users/list/active.json. For example: example.com.

If you host Discourse on a subfolder (for example: https://pipedream.com/community), enter the subfolder as a part of the domain (pipedream.com/community).

Create an API key in your Admin panel, and enter the associated api_username and api_key.

PostgreSQL Overview#

On Pipedream, you can leverage the PostgreSQL app to create workflows that automate database operations, synchronize data across platforms, and react to database events in real-time. Think handling new row entries, updating records from webhooks, or even compiling reports on a set schedule. Pipedream's serverless platform provides a powerful way to connect PostgreSQL with a variety of apps, enabling you to create tailored automation that fits your specific needs.

Action Code#

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

export default {
  name: "Execute SQL Query",
  key: "postgresql-execute-custom-query",
  description: "Execute a custom PostgreSQL query. See [our docs](https://pipedream.com/docs/databases/working-with-sql) to learn more about working with SQL in Pipedream.",
  version: "3.0.1",
  type: "action",
  props: {
    postgresql,
    // eslint-disable-next-line pipedream/props-description
    sql: {
      type: "sql",
      auth: {
        app: "postgresql",
      },
      label: "PostreSQL Query",
    },
  },
  async run({ $ }) {
    const args = this.postgresql.executeQueryAdapter(this.sql);
    const data = await this.postgresql.executeQuery(args);
    $.export("$summary", `Returned ${data.length} ${data.length === 1
      ? "row"
      : "rows"}`);
    return data;
  },
};

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 PostgreSQL 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.
