Implementing File Uploads in Real-time with Phoenix LiveView

Source: fly.io

Jason Stiebs' article discusses the complexities involved with file uploads in web applications and provides an insight into how Phoenix LiveView addresses these challenges. In the article, he explains that traditional file upload mechanisms are often limited and can become quite complex when dealing with large files and additional processing like verification, storage, and sharing. However, LiveView introduces an innovative approach that uses WebSockets for real-time file upload capabilities. Using the `allow_upload` function in the `mount` callback, along with `live_file_input`, developers can facilitate uploads directly within LiveView. Moreover, Jason introduces a new component, `LiveView.UploadWriter`, which allows developers to handle uploads in chunks and escort them wherever needed. This makes it possible to process files while they are being uploaded without needing to build complex infrastructure. The example shown includes uploading to multiple destinations, like the local file system and AWS S3. Through his tutorials on setup and use in real applications, Jason demonstrates that while no perfect solution may exist, LiveView provides powerful tools to simplify implementing robust upload features in web applications.

Implementing Unaccented Name Search in Postgres via Ecto
