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 Row Custom Query", key: "postgresql-new-row-custom-query", description: "Emit new event when new rows are returned from a custom query that you provide. [See the documentation](https://node-postgres.com/features/queries)", version: "2.0.8", type: "source", dedupe: "unique", props: { ...common.props, schema: { propDefinition: [ common.props.postgresql, "schema", ], }, table: { propDefinition: [ common.props.postgresql, "table", (c) => ({ schema: c.schema, }), ], }, column: { propDefinition: [ common.props.postgresql, "column", (c) => ({ table: c.table, schema: c.schema, }), ], }, query: { propDefinition: [ common.props.postgresql, "query", ], description: "Specify the query to select new or updated rows since the last poll. For example, `SELECT * FROM users WHERE country = 'US'`", }, values: { propDefinition: [ common.props.postgresql, "values", ], }, }, hooks: { async deploy() { if (this.values && !Array.isArray(this.values)) { throw new Error("No valid values provided. The values property must be an array."); } const numberOfValues = this.query?.match(/\$/g)?.length || 0; if (this.values && this.values.length !== numberOfValues) { throw new Error("The number of values provided does not match the number of values in the query."); } const isColumnUnique = await this.isColumnUnique(this.schema, this.table, this.column); if (!isColumnUnique) { throw new Error("The column selected contains duplicate values. Column must be unique"); } }, }, methods: { ...common.methods, generateMeta(row, column) { return { id: row[column], summary: "New Row", ts: Date.now(), }; }, }, async run() { const rows = await this.postgresql.executeQuery({ text: this.query, values: this.values, }); for (const row of rows) { const meta = this.generateMeta(row, this.column); this.$emit(row, meta); } }, };

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.
Table	`table`	`string`	Select a value from the drop down menu.
Column	`column`	`string`	Select a value from the drop down menu.
SQL Query	`query`	`string`	Specify the query to select new or updated rows since the last poll. For example, `SELECT * FROM users WHERE country = 'US'`
Values	`values`	`string[]`	List of values represented in your SQL Query above

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.

Discord Bot Overview#

The Discord Bot API unlocks the power to interact with Discord users and channels programmatically, making it possible to automate messages, manage servers, and integrate with other services. With Pipedream's serverless platform, you can create complex workflows that respond to events in Discord, process data, and trigger actions in other apps. This opens up opportunities for community engagement, content moderation, analytics, and more, without the overhead of managing infrastructure.

Action Code#

import { ConfigurationError } from "@pipedream/platform"; import common from "../../common.mjs"; import constants from "../../common/constants.mjs"; import utils from "../../common/utils.mjs"; const { discord } = common.props; export default { key: "discord_bot-send-message-with-file", name: "Send Message With File", description: "Post a message with an attached file. [See the docs here](https://discord.com/developers/docs/reference#uploading-files)", version: "1.0.2", annotations: { destructiveHint: false, openWorldHint: true, readOnlyHint: false, }, type: "action", props: { discord, ...common.props, file: { type: "string", label: "File Path Or Url", description: "Provide either a file URL or a path to a file in the `/tmp` directory (for example, `/tmp/example.pdf`)", }, message: { propDefinition: [ discord, "message", ], }, userId: { propDefinition: [ discord, "userId", (c) => ({ guildId: c.guildId, }), ], description: "Select either an user or a channel", optional: true, }, channelId: { propDefinition: [ discord, "channelId", ({ guildId }) => ({ guildId, notAllowedChannels: constants.NOT_ALLOWED_CHANNELS, }), ], description: "Select either a channel or an user", optional: true, }, embeds: { propDefinition: [ discord, "embeds", ], }, threadID: { propDefinition: [ discord, "threadID", ], }, username: { propDefinition: [ discord, "username", ], }, avatarURL: { propDefinition: [ discord, "avatarURL", ], }, includeSentViaPipedream: { type: "boolean", optional: true, default: true, label: "Include link to workflow", description: "Defaults to `true`, includes a link to this workflow at the end of your Discord message.", }, syncDir: { type: "dir", accessMode: "read", sync: true, optional: true, }, }, methods: { appendPipedreamText(message) { let content = message; if (typeof content !== "string") { content = JSON.stringify(content); } content += `\n\n${this.getSentViaPipedreamText()}`; return content; }, getSentViaPipedreamText() { const workflowId = process.env.PIPEDREAM_WORKFLOW_ID; // The link text is a URL without a protocol for consistency with the "Send via link" text in // Slack messages const linkText = `pipedream.com/@/${workflowId}?o=a&a=discord_webhook`; const link = `https://${linkText}`; return `Sent via [${linkText}](<${link}>)`; }, }, async run({ $ }) { if ((this.userId && this.channelId) || (!this.userId && !this.channelId)) { throw new ConfigurationError("You must select either an user or a channel."); } let channelId = this.channelId; if (this.userId) { const createDMChannelResponse = await this.discord.createDm({ $, recipientId: this.userId, }); channelId = createDMChannelResponse.id; } if (channelId) { const createMessageResponse = await this.discord.sendMessageWithFile({ $, channelId: channelId, threadID: this.threadID, username: this.username, file: this.file, embeds: utils.parseObject(this.embeds), avatarURL: this.avatarURL, content: this.includeSentViaPipedream ? this.appendPipedreamText(this.message) : this.message, }); $.export("$summary", "Message has been sent successfully"); return createMessageResponse; } else { throw new Error("Could not create or retrieve the channel!"); } }, };

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 Bot	`discord`	`app`	This component uses the Discord Bot app.
Guild	`guildId`	`string`	Select a value from the drop down menu.
File Path Or Url	`file`	`string`	Provide either a file URL or a path to a file in the `/tmp` directory (for example, `/tmp/example.pdf`)
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.
User	`userId`	`string`	Select a value from the drop down menu.
Channel	`channelId`	`string`	Select a value from the drop down menu.
Embeds	`embeds`	`any`	Embedded rich content (up to 6000 characters), this should be given as an array, e.g. `[{"title": "Hello, Embed!","description": "This is an embedded message."}]`. To pass data from another step, enter a reference using double curly brackets (e.g., `{{steps.mydata.$return_value}}`). Tip: Construct the `embeds` array in a Node.js code step, return it, and then pass the return value to this step.
Thread ID	`threadID`	`string`	If provided, the message will be posted to this thread
Username	`username`	`string`	Overrides the current username
Avatar URL	`avatarURL`	`string`	If used, it overrides the default avatar

syncDir	`syncDir`	`dir`

Action Authentication#

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

This app allows you to use the Discord API using your own Discord bot. If you don't want to use a custom bot, and you just need to use the Discord API, exit this screen and use the Discord app, instead.

If you want to use your own Discord bot, but haven't created one yet, see these instructions or watch this video. You'll need to add this bot to your server(s) to make successful API requests.

Once you've created your bot, you'll find the Bot token within the Bot section of your app. Enter that token below.
