Asynchronous CSV Parser with Ampt

This project showcases a simple CSV parser built using Ampt, a platform offering a high fidelity cloud environment for developing and running cloud-native applications using Node.js. The parser facilitates the uploading of CSV files through an API, processing the data, and then storing it in Ampt.

Dependencies

• @ampt/sdk
• express
• @ampt/data
• papaparse
• multer

Features

• File Uploading: Accepts CSV file uploads via a POST request.
• CSV Processing: Uses papaparse to parse the uploaded CSV, handling delimiters effectively.
• Data Storage: Employs Ampt's storage service to save parsed data.

API Endpoints

POST /api/csv

• Upload your CSV file to the server.
• The system will write the CSV to Ampt's storage service.
• Returns the status of the upload in a JSON format.

Event Listeners

• csvStorage.on("write:*.csv"): On a .csv file write event, the system reads and parses the CSV file and stores the processed data.

Test

Go to the URL of the developer sandbox that Ampt provides you. Upload a file, and check Ampt Dashoard to see the file and storage.
