Reverse Manifesto

A list of company-related stuff—mission, core values, and culture—that I research before considering applying to a job.

Sure, it’s nearly impossible to find a company that will satisfy every single point, but it helps me at least in finding better matches against my personal preferences and values.

The list doesn’t follow any specific order.

• Smart and inspiring leaders (CEO, founders), over megalomaniacs and tyrants
• Driven by a good and meaningful mission/cause, over greed (betting/casinos, scammy cryptos...)

constant-locals-loader for Webpack

This loader optimizes the output of mini-css-extract-plugin and/or css-loader, entirely removing the potentially large CSS classname mappings normally inlined into your bundle when using CSS Modules.

Run npm install constant-locals-loader, then make these changes in your Webpack config:

module.exports = {
 module: {

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette. See also my blog at www.janvsmachine.net.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

Reach UI Philosophy

Reach UI is an accessible foundation for React applications and design systems.

The three equally important goals are to be:

• Accessible
• Composable
• Stylable

I heard some points of criticism to how React deals with reactivity and it's focus on "purity". It's interesting because there are really two approaches evolving. There's a mutable + change tracking approach and there's an immutability + referential equality testing approach. It's difficult to mix and match them when you build new features on top. So that's why React has been pushing a bit harder on immutability lately to be able to build on top of it. Both have various tradeoffs but others are doing good research in other areas, so we've decided to focus on this direction and see where it leads us.

I did want to address a few points that I didn't see get enough consideration around the tradeoffs. So here's a small brain dump.

"Compiled output results in smaller apps" - E.g. Svelte apps start smaller but the compiler output is 3-4x larger per component than the equivalent VDOM approach. This is mostly due to the code that is usually shared in the VDOM "VM" needs to be inlined into each component. The tr
