Interceptors Are Functions Too

I could not agree more with my colleague and friend Travis Johnson's opinion that "[INTERCEPTORS ARE SO COOL][iasc]!" In that post, he succinctly describes the [Interceptor pattern][pattern] as used adroitly by [OkHttp][okhttp]. But, as is often the case, I believe a complicated object-oriented pattern obscures the simple functional gem within it.

What is an Interceptor?

I'll quote liberally from [OkHttp's documentation on the topic][okhttp-interceptor]:

Interceptors are a powerful mechanism that can monitor, rewrite, and retry calls. […] >

Today we are going to create a FIFO (First In First Out) type file stream between the browser and a local application.

The idea is to create a local file in the browser, when the file is created the local application writes data to the newly created file, in the browser we will read the data written to the file up to that point, then truncate the file to size 0, repeat, when the writing and reading of the file are complete we will remove the file from the local file system.

In this way we can configure our local application to watch for the creation of specific named files, each performing a discrete process, and stream data from the local application to the file, without using networking.

We'll be using Deno in this example for the local application. Use whatever local application you want. Node.js, QuickJS, C,

How to Sell Elixir AGAIN (2023)

Presented by Evadne Wu at Code BEAM Lite in Stockholm, Sweden on 12 May 2023

Synopsis

We have celebrated 10 years of Elixir and also nearly 25 years of Erlang since the open source release in December 1998.

Most of the libraries that were needed to make the ecosystem viable have been built, talks given, books written, conferences held and training sessions provided. A new generation of companies have been built on top of the Elixir / Erlang ecosystem. In all measures, we have achieved further reach and maturity than 5 years ago.
