Mitchell is very passionate about using and teaching Elixir and has been doing so for the last 5 years.
He is the author/maintainer of a few libraries: Wallaby, Temple, an Elixir plugin for Neovim and frequently writes articles on his blog explaining interesting topics and showcasing his latest open source activities.
Mitchell is currently work at Simplebet as a Senior Software Engineer.
Creating your own generic process abstraction can allow developers to focus on their implementation and not worry about boilerplate. Examples of this exist in OTP with `gen_server`, in Elixir’s Task, and in libraries like Phoenix with Channels.
Using `proc_lib`, you can quickly create your own process abstractions that are OTP-compliant: they’re able to be supervised, respond to debugging tools like `sys:get_state/1`, and have their own custom callbacks (`handle_foo`). This is how `gen_server` and `gen_statem` are implemented.
In this talk, we’ll explore all the different features that you’ve seen in OTP-compliant processes, what we might want in our own, and hypothesize what it takes to build one. We’ll take this hypothesis and walk through building an abstraction for making custom language servers using the Language Server Protocol.
In the end, we’ll see that in just a few lines of code, we can easily build our own OTP-compliant process abstraction and use it to build a process.
