i run https://howtotestfrontend.com, a site full of resources and tips on how to test React frontend code.

i would guess most links i post are either about testing, frontend development, typescript, etc etc.

i also post interesting links i found around the web. the only site that is mine is www.howtotestfrontend.com, the rest are just ones i think might be interesting on hacker news.

+1 very confusing name for another mongodb compatible db.

Yep. I think there are so many new apps, when I run a `npx skills add ...` , the list of what tools (like claude code, open code, etc) to install skills in is getting larger every time I use it.

I will check it out though.

100%. its a horrible code smell, and AI loves to jest.mock (or vi.mock()). (The most recent blog post on my site covers this as one of the things to look out for in AI generated tests...)

in JS (with Jest/Vitest) it is far too easy to call mock()...

yup vitest is great (my default choice for new projects).

vitest browser mode is really nice too. (new-ish feature, although at this point it isn't exactly new).

learn step by step the main features of both Jest and Vitest (they're very similar for most common usages) in these interactive4 lessons

not sure how interesting to others, but i thought this was really cool.

(I am not affiliated with posthog at all. Just typed an incorrect address and came across it.)

Has anyone got any good resources for something like this? I haven't touched C in years, and never worked on anything game-like. But it does look like a really interesting project to start something like this.

tldr - `tsc` can be replaced with `tsgo`. `eslint` replaced by `oxlint`, and `prettier` replaced with `oxfmt

just saw this today - "whenwords, a relative time formatting library that contains no code." I wonder with AI this will become a popular thing soon that we see other 'libraries' doing... provide good specs, leave it to AI (And trust ai) to interpret

If GH has an issue, it seems to always be around 4pm or 5pm GMT. I'm starting to think that i should avoid any planned production releases around this time.

while this approach is useful, i think the diff is too small to catch a lot of bugs.

i use https://www.coderabbit.ai/ and it tends to be aware of files that aren't in the diff, and definitely can see the rest of the file your are editing (not just the lines in the diff)

I find the jetbrains IDEs (like Webstorm) has the best UI interface for this. Selectively commit specific lines from your changes.

Wow, imagine this 10 years ago. It would never have been an option.

Same, it is a question of time.

For me, weekends only... I used to do a lot of freelance work (years ago...more than a decade ago), somehow I used to find more time then for side projects... with full time employment is is impossible to find the time.
