The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

`package.json`

County/State level geocoding in postgis

If your geocoding task requires only US county and state level information, you can avoid a third party web service dependency using open data and postgis.

Data source

Natural Earth counties, US only.

Why using the `children` prop makes `React.memo()` not work

I've recently ran into a pitfall of [React.memo()][memo] that seems generally overlooked; skimming over the top results in Google just finds it mentioned in passing in a [React issue][regit], but not in the [FAQ] or API [overview][react-api], and not in the articles that set out to explain React.memo() (at least the ones I looked at). The issue is specifically that nesting children defeats memoization, unless the children are just plain text. To give a simplified code example:

const Memoized = React.memo(({ children }) => (<div>{children}</div>));
// Won't ever re-render
<Memoized>bar</Memoized>
// Will re-render every time; the memoization does nothing

Why

Ripgrep is a fast search tool like grep. It's mostly a drop-in replacement for ag, also know as the Silver Searcher.

helm-ag is a fantastic package for Emacs that allows you to display search results in a buffer. You can also jump to locations of matches. Despite the name, helm-ag works with ripgrep (rg) as well as with ag.
