What is this?

When you register a new domain and start hosting content there, people might not be able to view it if they're behind some kind of security software or hardware that filters by domain (e.g. web/content/DNS filters). This is because the domain is new and hasn't been categorized by the security filter, and filters commonly don't allow traffic to uncategorized domains.

Usually people can contact their security provider to request the domain to be unblocked, but:

• this process can take a few days or longer
• sometimes this has to be handled by IT internally and might not be escalated to the provider
  • because of this, sometimes the domain will just be unblocked for a set of people (e.g. everyone at a company) and other companies have to repeat this
• depending on how the filtering is implemented (e.g. how requests/responses are intercepted), websites might just appear broken instead of getting an explicit message about the website being blocked
• usually this approach is reactionary, because

Ecto Changeset Demo and Talk

What is Ecto?

• Historic personal use of Active Record pattern in PHP, Rails, iOS dev.
• Ecto described itself as a toolkit for data mapping and language integrated query for Elixir.
• Changeset were (for me) a new concept that I've really come to appriciate.

Many of the demos you'll see come from Ecto's own Getting Started and I encourage you to check it out as well.

1. Begin with scaffolding a create-react-app, then update your package.json build script (replace DIR_TO_PHX_APP with the path to your phoenix app)

"build": "react-scripts build && rm -rf DIR_TO_PHX_APP/priv/static/build && mv build DIR_TO_PHX_APP/priv/static/build",

This will move your prod build files to DIR_TO_PHX_APP/priv/static/build on build

2. Run npm run build

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
