Microbrowsers are Everywhere (via) Colin Bendell introduces a new-to-me term, “microbrowsers”, to describe the user-agents which hit websites to generate unfurled link previews in messenger apps. Twitter and Facebook first popularized them, but today you’re likely getting far more preview-generating traffic from chat clients such as iMessage, WhatsApp and Slack (which won’t execute script and ignore cookies, and hence won’t show up in Google Analytics). Lots of great tips here—one example: if you provide three og:image meta tags iMessage will render them as a collage. # 18th December 2019, 8:32 am

Fast Autocomplete Search for Your Website (via) I wrote a tutorial for the 24 ways advent calendar on building fast autocomplete search for a website on top of Datasette and SQLite. I built the demo against 24 ways itself—I used wget to recursively fetch all 330 articles as HTML, then wrote code in a Jupyter notebook to extract the raw data from them (with BeautifulSoup) and load them into SQLite using my sqlite-utils Python library. I deployed the resulting database using Datasette, then wrote some vanilla JavaScript to implement autocomplete using fast SQL queries against the Datasette JSON API. # 19th December 2018, 12:26 am

Tracking Christmas Cheer with Google Charts. Brian Suda’s Google Charts tutorial on 24 ways has proved invaluable for figuring out how to handle grid lines and axis labels, both of which are pretty unintuitive (and not hugely helped by the official documentation). # 26th May 2008, 9:43 pm

Unobtrusively Mapping Microformats with jQuery

Microformats are everywhere. You can’t shake an electronic stick these days without accidentally poking a microformat-enabled site, and many developers use microformats as a matter of course. And why not? After all, why invent your own class names when you can re-use pre-defined ones that give your site extra functionality for free?

Don’t be eval()

JavaScript is an interpreted language, and like so many of its peers it includes the all powerful eval() function. eval() takes a string and executes it as if it were regular JavaScript code. It’s incredibly powerful and incredibly easy to abuse in ways that make your code slower and harder to maintain. As a general rule, if you’re using eval() there’s probably something wrong with your design.
