how do I download a file from an S3 bucket once I have the file URL from a trigger?
To download a file from an S3 bucket once you have the file URL from a trigger, you can use a similar approach to the examples provided in the Pipedream documentation for downloading files to the /tmp directory. Here’s a Node.js code snippet tailored for your use case: import stream from "stream"; import { promisify } from "util"; import fs from "fs"; import got from "got"; // Assuming `fileUrl` is the URL of the file you received from the trigger const fileUrl = steps.trigger.event.body.fileUrl; // Replace with the actual path to the URL in your trigger data const filename = "downloaded_file"; // Replace with your desired filename const pipeline = promisify(stream.pipeline); await pipeline( got.stream(fileUrl), fs.createWriteStream(`/tmp/${filename}`) ); // The file is now downloaded to the /tmp directory This code uses the got library to stream the file from the S3 URL and the fs library to write the stream to a file in the /tmp directory. Make sure to replace steps.trigger.event.body.fileUrl with the actual path to the URL in your trigger data and downloaded_file with your desired filename. You can then read or process this file in subsequent steps of your workflow. For more information on working with files in Pipedream, please refer to the documentation on downloading files and working with the /tmp directory.
how do I authenticate when i am downloading a file from an S3 bucket once I have the file URL from a trigger?
To authenticate and download a file from an S3 bucket using a file URL you received from a trigger in Pipedream, you’ll typically use AWS SDK or an HTTP client, depending on the authentication method required by your S3 bucket. If your S3 bucket is public, you might directly download the file using an HTTP client. However, for private buckets, you’ll need to use AWS SDK with proper authentication. Here’s an example using the AWS SDK for Node.js, assuming you have the necessary AWS credentials (Access Key ID and Secret Access Key) and the S3 bucket is private: import { S3 } from "aws-sdk"; import { axios } from "@pipedream/platform"; import fs from "fs"; export default defineComponent({ async run({ steps, $ }) { // Initialize the S3 client const s3 = new S3({ accessKeyId: process.env.AWS_ACCESS_KEY_ID, // Set your AWS Access Key ID in environment variables secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY, // Set your AWS Secret Access Key in environment variables }); // Parse the S3 file URL to get the bucket name and file key const fileUrl = "YOUR_S3_FILE_URL_HERE"; // Replace with your S3 file URL const url = new URL(fileUrl); const bucketName = url.hostname.split(".")[0]; const fileKey = url.pathname.substring(1); // Use the S3 client to get the file object const params = { Bucket: bucketName, Key: fileKey, }; const file = await s3.getObject(params).promise(); // Optionally, save the file to the /tmp directory const filePath = `/tmp/${fileKey}`; fs.writeFileSync(filePath, file.Body); // Or directly return the file content return file.Body; }, }); In this example, replace "YOUR_S3_FILE_URL_HERE" with the actual S3 file URL you received from the trigger. Also, ensure you have set your AWS Access Key ID and AWS Secret Access Key as environment variables in Pipedream for secure access. This example demonstrates downloading a file from an S3 bucket using the AWS SDK for JavaScript in Node.js. It assumes you have the necessary permissions to access the file in the bucket. If your use case involves different authentication methods or additional requirements, please provide more details so I
There’s also a S3 download option that was added recently.
thank you that is what i ended up using, the /tmp one
