Bruce Lawson's personal site » A first look at the Web Install API

A first look at the Web Install API brucelawson.co.uk/2025/a-first... I took this Microsoft-stewarded API for a test-drive. Thrills and spills, guaranteed!

The Web Install API is ready for testing We're happy to announce that the Web Install API is now ready for testing on your own site, as an origin trial in Microsoft E

Currently trying out the Web Install API (from the MS Edge team), and liking what I see. Write-up incoming. Nice work, @diekus.bsky.social et al. (Niggle: for a non-Edge user, finding the *beta* was hard. It kinda works on Chrome Canary but UI not hooked up yet). blogs.windows.com/msedgedev/20...

Creating a universal app store for PWAs seems like an obvious win here vs. heuristics triggered installs. But think about smaller, more bespoke app stores! An app store for your intranet apps. An app store for your webring of online mutuals. An app store for kid-friendly apps. That's fun territory.

The Web Install API is very promising and even enables web apps to install other web apps.

Check the demo: whatpwacando.today/installation

rejects the promise. (see how here: github.com/MicrosoftEdg...)

Mind-blowing they have to be forced imho. Them and Samsung gatekeeping app minting is a bit of a jerk move. (Just my personal opinion, not my employer's)

How the App Store Helped Kill My Startup,and Why That Should Matter to You Not being allowed into the App Store played a pivotal role in the challenges my startup, Freyja, faced, even if it wasn’t the sole reason for its struggles.

Diego and friends in Primavera Sound. 4 people in front of a structure that says PRIMAVERA SOUND.

And a very fun @primavera-sound.bsky.social in beautiful Barcelona to end a great week.

Hung out with @tomayac.com and @christianliebel.com in A Coruña last week.

don't get me wrong, I like the design, but it did spark my curiosity about how accessible these are. 🤔

and on this `liquid glass`, it looks cool, but I am a bit concerned about the accessibility implications of these designs?

For example, look at the contrast in the text for artist's name. Also the `clear` theme looks like it can be challenging to distinguish things. Is this form over function?

Just saw the new `Liquid Glass` design language from Apple. Interestingly, I think it is a good opportunity to remind web folks of this explainer that can bring this type of materials to web apps: github.com/MicrosoftEdg...

Thumbs up if you approve 😉

been all of last week in Spain, the first half for a great @webengineshackfest.org in A Coruña where I met lovely Igalians and the end of the week in Barcelona for @primavera-sound.bsky.social
