Getting Started#

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

Select this integration
Configure the New Table trigger
1. Connect your PostgreSQL account
2. Configure Polling Interval
3. Select a Schema
Configure the List Assignments action
1. Connect your Google Classroom account
2. Select a Course
3. Optional- Select a Assignment Type
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 Table on PostgreSQL

Description:Emit new event when a new table is added to the database. [See the documentation](https://node-postgres.com/features/queries)

Version:2.0.8

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.

Trigger Code#

import common from "../common.mjs"; export default { ...common, name: "New Table", key: "postgresql-new-table", description: "Emit new event when a new table is added to the database. [See the documentation](https://node-postgres.com/features/queries)", version: "2.0.8", type: "source", props: { ...common.props, schema: { propDefinition: [ common.props.postgresql, "schema", ], }, }, async run() { const previousTables = this._getPreviousValues() || []; const tables = await this.postgresql.getTables(this.schema); const newTables = tables.filter((table) => !previousTables.includes(table)); for (const table of newTables) { const meta = this.generateMeta(table); this.$emit(table, meta); } this._setPreviousValues(tables); }, };

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
Schema	`schema`	`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.

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

About PostgreSQL#

PostgreSQL is a free and open-source relational database management system emphasizing extensibility and SQL compliance.

Action#

List Assignments on Google Classroom

Description:Retrieve a list of assignments for a course. [See the documentation](https://developers.google.com/classroom/reference/rest/v1/courses.courseWork/list)

Version:0.0.3

Google Classroom Overview#

The Google Classroom API lets you tap into the educational space by managing courses, assignments, and student interactions programmatically. With this API, you can automate course creation, roster management, and content distribution, effectively bridging the gap between various educational tools and platforms. Leveraging Pipedream's serverless execution environment, you can build powerful workflows that respond to events in Classroom, sync data across platforms, and streamline the educational process for teachers and students alike.

Action Code#

import googleClassroom from "../../google_classroom.app.mjs"; import utils from "../../common/utils.mjs"; export default { key: "google_classroom-list-assignments", name: "List Assignments", description: "Retrieve a list of assignments for a course. [See the documentation](https://developers.google.com/classroom/reference/rest/v1/courses.courseWork/list)", version: "0.0.3", annotations: { destructiveHint: false, openWorldHint: true, readOnlyHint: true, }, type: "action", props: { googleClassroom, course: { propDefinition: [ googleClassroom, "course", (c) => ({ courseStates: c.courseStates, }), ], }, assignmentType: { type: "string", label: "Assignment Type", description: "Get only past due assignments, not yet due assignments, or all assignments", options: [ "past due", "not yet due", "all", ], default: "all", optional: true, }, }, methods: { getDueTs(dueDate, dueTime) { const { year, month, day, } = dueDate; let dateString = `${year}-${utils.padZero(month)}-${utils.padZero(day)}`; if (dueTime) { const { hours, minutes, } = dueTime; dateString += `T${utils.padZero(hours)}:${minutes ? utils.padZero(minutes) : "00"}:00`; } return Date.parse(dateString); }, isRelevant(assignment) { if (!this.assignmentType || this.assignmentType === "all") { return true; } if (!assignment.dueDate) { return false; } const dueDate = this.getDueTs(assignment.dueDate, assignment.dueTime); if (this.assignmentType === "past due") { return dueDate < Date.now(); } if (this.assignmentType === "not yet due") { return dueDate > Date.now(); } }, }, async run({ $ }) { const params = { courseId: this.course, }; const assignments = []; do { const { courseWork, nextPageToken, } = await this.googleClassroom.listCoursework(params); if (!courseWork?.length) { break; } for (const assignment of courseWork) { if (this.isRelevant(assignment)) { assignments.push(assignment); } } params.pageToken = nextPageToken; } while (params.pageToken); $.export("$summary", `Successfully retrieved ${assignments.length} assignment${assignments.length === 1 ? "" : "s"}.`); return assignments; }, };

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
Google Classroom	`googleClassroom`	`app`	This component uses the Google Classroom app.
Course	`course`	`string`	Select a value from the drop down menu.
Assignment Type	`assignmentType`	`string`	Select a value from the drop down menu:`past duenot yet dueall`

Action Authentication#

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

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

https://www.googleapis.com/auth/userinfo.emailhttps://www.googleapis.com/auth/userinfo.profilehttps://www.googleapis.com/auth/classroom.courses.readonlyhttps://www.googleapis.com/auth/classroom.coursework.studentshttps://www.googleapis.com/auth/classroom.coursework.mehttps://www.googleapis.com/auth/classroom.announcements.readonly
