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 Item in Feed on RSS

Description:Emit new items from an RSS feed

Version:1.2.7

Key:rss-new-item-in-feed

RSS Overview#

The RSS app allows users to automatically fetch and parse updates from web feeds. This functionality is pivotal for staying abreast of content changes or updates from websites, blogs, and news outlets that offer RSS feeds. With Pipedream, you can harness the RSS API to trigger workflows that enable a broad range of automations, like content aggregation, monitoring for specific keywords, notifications, and data synchronization across platforms.

Trigger Code#

import { defineSource } from "@pipedream/types";
import rss from "../../app/rss.app.mjs";
import rssCommon from "../common/common.mjs";
export default defineSource({
    ...rssCommon,

            }

            this.$emit(item, meta);

	`timer`	`$.interface.timer`	How often you want to poll the feed for new items
Feed URL	`url`	`string`	Enter the URL for any public RSS feed
Published After	`publishedAfter`	`string`	Emit items published after the specified date in ISO 8601 format .e.g `2022-12-07T12:57:10+07:00`

Trigger Authentication#

AWS Overview#

The AWS API unlocks endless possibilities for automation with Pipedream. With this powerful combo, you can manage your AWS services and resources, automate deployment workflows, process data, and react to events across your AWS infrastructure. Pipedream offers a serverless platform for creating workflows triggered by various events that can execute AWS SDK functions, making it an efficient tool to integrate, automate, and orchestrate tasks across AWS services and other apps.

Action Code#

import common from "../../common/common-dynamodb.mjs";
import {
  toSingleLineString,
  attemptToParseJSON,
} from "../../common/utils.mjs";

export default {
  ...common,
  key: "aws-dynamodb-query",
  name: "DynamoDB - Query",
  description: toSingleLineString(`
    The query operation finds items based on primary key values.
    [See docs](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-dynamodb/classes/querycommand.html)
  `),
  version: "0.5.1",
  type: "action",
  props: {
    aws: common.props.aws,
    region: common.props.region,
    tableName: common.props.tableName,
    keyConditionExpression: common.props.keyConditionExpression,
    projectionExpression: common.props.projectionExpression,
    expressionAttributeNames: common.props.expressionAttributeNames,
    expressionAttributeValues: common.props.expressionAttributeValues,
  },
  async run({ $ }) {
    const params = {
      TableName: this.tableName,
      KeyConditionExpression: this.keyConditionExpression,
      ProjectionExpression: this.projectionExpression,
      ExpressionAttributeNames: attemptToParseJSON(this.expressionAttributeNames),
      ExpressionAttributeValues: attemptToParseJSON(this.expressionAttributeValues),
    };

    const response = await this.aws.pagination(
      this.query,
      params,
      "ExclusiveStartKey",
      "LastEvaluatedKey",
    );

    const s = response.Items.length === 1
      ? ""
      : "s";
    $.export("$summary", `Query returned ${response.Items.length} item${s}`);
    return response;
  },
};

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
AWS	`aws`	`app`	This component uses the AWS app.
AWS Region	`region`	`string`	Select a value from the drop down menu.
Table Name	`tableName`	`string`	Select a value from the drop down menu.
Key Condition Expression	`keyConditionExpression`	`string`	The condition that specifies the key values for items to be retrieved by the Query action. Example: `partitionKeyName = :partitionkeyval AND sortKeyName = :sortkeyval` See the docs
Projection Expression	`projectionExpression`	`string`	A string that identifies one or more attributes to retrieve from the specified table or index. If no attribute names are specified, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result.
Expression Attribute Names	`expressionAttributeNames`	`string`	One or more substitution tokens for attribute names in an expression. Example: `{ "#execs": "execs" }` See the docs
Expression Attribute Values	`expressionAttributeValues`	`string`	One or more values that can be substituted in an expression. Use the : (colon) character in an expression to dereference an attribute value. Example: `{ ":echo": { "S": "echo" }, ":oneh": { "N": "100" } }` See the docs

Action Authentication#

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

Follow the AWS Instructions for creating an IAM user with an associated access and secret key.

As a best practice, attach the minimum set of IAM permissions necessary to perform the specific task in Pipedream. If your workflow only needs to perform a single API call, you should create a user and associate an IAM group / policy with permission to do only that task. You can create as many linked AWS accounts in Pipedream as you'd like.

Enter your access and secret key below.
