Being new to Elixir and Phoenix, I spend quite some time in the projects’ documentation. One thing that stood out for me recently is the first sentence of Phoenix’s Plug documentation: “Plug lives at the heart of Phoenix’s HTTP layer and Phoenix puts Plug front and center.”

So naturally, I felt compelled to take a deeper dive into Plug and understand it better. I hope the article helps you out as well, you can read it here.

https://medium.com/blackode/how-to-perform-hot-code-swapping-in-elixir-afc824860012

Hot code swapping is replacing or adding components without stopping or shutting down the system. It is frequently called as hot-plugging.

In software development, hot swapping is used to upgrade or update the system without interrupting the current running system. It helps us with less downtime at the time of upgrading.

OK! Stories are always good to hear. Let’s dive into the code.

• Umbrella projects in single-language IDEs like Rubymine using multiple IDE Projects in one window.
• Ignore assets to prevent phoenix and phoenix_html mix.exs files being imported from assets/node_modules symlinks
• Remove unused variables in Elixir debugger server
• Protect from spurious AssertionError from VirtualFilePointerContainer when walking SDK paths.
• Use :path to get external path to deps not in deps folder of project root.
• Ignore :tag and :ref when determining path to deps.
• No longer use forked version of TerminalExecutionConsole, so that IEx and IEx Mix run configurations work in IntelliJ IDEA 2018.3.
