Creating an in memory zip file
Hi there,
My application is related to the creation of educational content and I have added a route to my application that is reponsible for creating an in-memory zip file that contains the necessary files for a SCORM 1.2 package for loading into LMS platforms.
I have experience with SCORM packages (as boring and mundane as they are) and I have started playing with the erlang :zip module to create my in memory zip file which is then sent on to the users browser.
However, I am not sure which area of elixir I should be looking in when it comes to creating the in-memory files that are used to generate my module. For example, one of the files in the SCORM package is a simple HTML file that includes an IFRAME to content in my application.
Whats the neatest and most readable way to create this HTML file in-memory? I was thinking Phoenix.View.render_to_iodata but then wasn’t sure of the implications of including templates in my templates directory that aren’t used by any views that are accessible via URL…

I’ve had a similar problem to solve. Create a zip file in memory from bunch of files that I had content in strings. And then base64 it. The safest way is to use zip module from erlang. Theres a create method that takes filename, list of files and options where you can pass that you wanna work in memory. This is what I came up with.
{:ok, {_filename, data}} = :zip.create("extension.zip", [{'file1.txt', "content of file 1"}, {'file2.txt',"content of file 2"}], [:memory])
data |> Base.encode64
