cs4140 Notes: 30 File Data

Two teams need to deal with file data:

• GregsList needs image uploads.
• BingeCast needs MP3 files.

Towards this end I’m going to review what a file is and how to deal with it in both Elixir and JS.

Elixir:

• bin_write / read
• Temp uploads
• Copying file
• Uploads directory

JS:

• FileReader
