A zero-dependency, transparent, in-memory, streaming write-on-update JavaScript database for the Small Web that persists to a JavaScript transaction log.

To really drive home the above 👆 point that 100% test coverage does not mean ‘bug free’, just found a bug in JSDB¹ 5.0.0 where running JSON.stringify() on a complex custom object (actually: the automatic Proxy of the custom object created by JSDB) results in an error.

Already have a failing test and about to implement fix.

(It’s at this point where the test harness is invaluable.)

If you use a parameter object in JavaScript, even if you specify its shape using JSDoc, you’ll only get errors if required properties are missing; not if there are extra properties provided.

e.g.,

```js
class A {
/**
@param {{
id:string
}} params
*/
constructor (params) {
Object.assign(this, params)
}
}

// Error:
new A({})

// No error:
new A({id: 'x', foo:'bar'})
```

According to this thread, it’s a fact-of-life:

Philosophically, JSDB – which writes out to native JavaScript logs – is very much the JavaScript version of SWX, the native data format for Flash that I released around 2007 (where data was written out in native SWF format). I have to say that I’m glad I didn’t have to reverse engineer SWF bytecode this time around :)

Here’s a video of a younger me doing an impromptu demo of SWX at some conference or other from 16 years ago.

100% test coverage doesn’t mean your code’s bug free but it did just lead me to find and fix an issue in JavaScript Database (JSDB)¹ with a code path that wasn’t being hit that I would have otherwise missed because it was causing the relevant test to pass.

¹ JSDB is a zero-dependency, transparent, in-memory, streaming write-on-update JavaScript database for the Small Web that persists to a JavaScript transaction log (an append-only log).

Just wrote a note about a little gotcha with default values for destructured properties of parameter objects in JavaScript that has gotten me a few times:

Realised last night that JavaScript Database (JSDB) doesn’t run the constructor on persisted custom objects (https://codeberg.org/small-tech/jsdb#custom-data-types) when deserialising them because I didn’t know that you apparently have to define your constructor manually when using Object.create().

Will fix it today but it’s something to watch out for if you’re using Object.create() directly.

#Fedify is an #ActivityPub server framework in #TypeScript & #JavaScript. It aims to eliminate the complexity and redundant boilerplate code when building a federated server app, so that you can focus on your business logic and user experience.

The key features it provides currently are:

• Type-safe objects for Activity Vocabulary (including some vendor-specific extensions)
• #WebFinger client and server
• HTTP Signatures
• Middleware for handling webhooks
• #NodeInfo protocol
• #Node.js, #Deno, and #Bun support

If you're curious, take a look at the Fedify website! There's comprehensive docs, a demo, a tutorial, example code, and more:

Little web dev tip: if you have just one address field in your HTML form (e.g., a textarea) but you still want the person filling it in to avail themselves of autocomplete, here’s a little reusable snippet you can use to achieve that:

https://codeberg.org/aral/gists/src/branch/main/single-html-address-field-with-autocomplete-using-javascript.md

(Ideally the web spec should be extended to include a full-address value for the autocomplete attribute.)

This is a niche one and will likely not affect any of the (three?) people playing with Kitten¹ right now but, in any case:

If you persist custom types to your Kitten database, you might be hit by this bug that was introduced when I released versions of Kitten with minified identifiers.

I briefly wrote about what happened, how you can identify if you’re affected, and how you can fix it here:

Just improved the display of error messages in Kitten¹.

They should be far more robust now.

Run `kitten update` to get the latest.
