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 or Modified File or Folder on Dropbox

Description:Emit new event when a file or folder is added or modified. Make sure the number of files/folders in the watched folder does not exceed 4000.

Version:0.0.19

Dropbox Overview#

The Dropbox API on Pipedream enables you to automate file and folder operations, streamlining workflows that involve storing, syncing, and sharing content. With this API, you can programmatically manage files, set up event-driven triggers based on changes within Dropbox, and leverage Pipedream's capabilities to connect with hundreds of other apps for extended automation scenarios. It's ideal for building custom file management solutions, archiving systems, or collaborative content workflows without writing extensive code.

Trigger Code#

import common from "../common/common.mjs"; import sampleEmit from "./test-event.mjs"; export default { ...common, dedupe: "unique", type: "source", key: "dropbox-all-updates", name: "New or Modified File or Folder", version: "0.0.19", description: "Emit new event when a file or folder is added or modified. Make sure the number of files/folders in the watched folder does not exceed 4000.", props: { ...common.props, includeMediaInfo: { label: "Include Media Info", type: "boolean", description: "Emit media info for photo and video files (incurs an additional API call)", default: false, }, includeLink: { label: "Include Link", type: "boolean", description: "Emit temporary download link for files (incurs an additional API call)", default: false, }, }, hooks: { async activate() { await this.getHistoricalEvents(this.getFileTypes()); const state = await this.dropbox.initState(this); this._setDropboxState(state); }, }, methods: { ...common.methods, getFileTypes() { return [ "file", "folder", ]; }, }, async run() { const state = this._getDropboxState(); const { ret: updates, state: newState, } = await this.dropbox.getUpdates(this, state); this._setDropboxState(newState); for (let update of updates) { let file = { ...update, }; const fileTypes = this.getFileTypes(); if (!fileTypes.includes(file[".tag"])) { continue; } if (this.includeMediaInfo && file[".tag"] === "file") { file = await this.getMediaInfo(update); } if (this.includeLink && file[".tag"] === "file") { file.link = await this.getTemporaryLink(update); } // new unique identification from merging the file id and the last file revision const id = update[".tag"] === "file" ? `${file.id}-${file.rev}` : `${file.id}-${newState.cursor}`; this.$emit(file, this.getMeta(id, file.path_display || file.id)); } }, sampleEmit, };

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
Dropbox	`dropbox`	`app`	This component uses the Dropbox app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Path	`path`	`string`	Select a value from the drop down menu.
Recursive	`recursive`	`boolean`	Also watch sub-directories and their contents.
	`dropboxApphook`	`$.interface.apphook`
Include Media Info	`includeMediaInfo`	`boolean`	Emit media info for photo and video files (incurs an additional API call)
Include Link	`includeLink`	`boolean`	Emit temporary download link for files (incurs an additional API call)

Trigger Authentication#

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

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

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: "Find Row With Custom Query", key: "postgresql-find-row-custom-query", description: "Finds a row in a table via a custom query. [See the documentation](https://node-postgres.com/features/queries)", version: "2.0.9", annotations: { destructiveHint: false, openWorldHint: true, readOnlyHint: true, }, type: "action", props: { postgresql, query: { propDefinition: [ postgresql, "query", ], }, values: { propDefinition: [ postgresql, "values", ], }, }, async run({ $ }) { const { query, values = [], } = this; if (!Array.isArray(values)) { throw new Error("No valid values provided. The values property must be an array."); } if (this.values) { const numberOfValues = query?.match(/\$/g)?.length || 0; if (values.length !== numberOfValues) { throw new Error("The number of values provided does not match the number of values in the query."); } } if (!query.toLowerCase().includes("select")) { throw new Error("Need be a `SELECT` statement query. Read more about [SELECT queries here](https://www.w3schools.com/sql/sql_select.asp)"); } const res = await this.postgresql.executeQuery({ text: query, values, errorMsg: "Query not executed due to an error. ", }); $.export("$summary", "Successfully executed query"); return res; }, };

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
PostgreSQL	`postgresql`	`app`	This component uses the PostgreSQL app.
SQL Query	`query`	`string`	Your custom SQL Query using `$1`, `$2`... to represent values (eg. `INSERT INTO users(name, email) VALUES($1, $2)`
Values	`values`	`string[]`	List of values represented in your SQL Query above

Action 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
