CS 347: Lecture 23 – Hosting User Files

November 10, 2020 by Chris Johnson. Filed under fall-2020, lectures, webdev.

Dear students:

Many web apps evolve into miniature content management systems. Users upload their content to the back-end, and the front-end serves as an interface to this centralized storage. Sometimes the content is simple text and numbers that are stored in a database. But sometimes the data is more complex, like images and other media. In this lecture, we explore build a service that allows the user to upload images, which are stored not in a database but in the file system.

Here’s your TODO list:

• There’s no blog post this week.
• Watch Hosting Files.
• Watch Serving Out Files.
• Watch Consuming Images.
• Watch Uploading Images.
• Watch Dealing with Slow Uploads.
• On Thursday, we’ll have a peer review for project 2. Be prepared to discuss and demonstrate your progress, celebrate difficulties that you’ve overcome, and strategize about what needs to be accomplished next.

See you next time.

Sincerely,
