Made a little logo for JSDB (JavaScript Database)

Better (six years) late than never? :)

🥳 JavaScript Database (JSDB)¹ version 7.0.0 released

- *Breaking change* JSTable.PERSIST event now uses a parameter object with properties for `type`, `keypath`, `value`, `change`, and `table`. This should make listening for events on your databases much nicer to author. e.g., a snippet from Catalyst² I’m working on:

```js
const settingsTable = db.settings['__table__']
const JSTable = settingsTable.constructor

settingsTable.addListener(JSTable.PERSIST, ({ keypath, value }) => {
switch (keypath) {
case 'servers.serverPoolSize':
console.info('New server pool size requested', value)
this.updateServerPool()
break
// etc.
}
})
```

This new version of JSDB is not in the latest Kitten³ yet as it is a breaking change and I want to make sure I update my sites/apps first if needed. I should have it integrated tomorrow.

To see the simple use case for JSDB in Kitten (the default untyped database that’s easy to get started with and perfect for quick experiments, little sites, etc.), see: https://kitten.small-web.org/tutorials/persistence/

For a more advanced tutorial for creating your own typed databases in Kitten, see the Database App Modules tutorial: https://kitten.small-web.org/tutorials/database-app-modules/

For another example, see: https://codeberg.org/small-tech/jsdb/#table-events

The built-in database backup and restore feature in Kitten¹ (that actually works and is in the Kitten Settings section of every Kitten app) just saved my ass (again) :)

Thank you, past me ;)

🥳 JavaScript Database (JSDB) version 6.1.4 released:

• Adds TypeScript type definitions

Been meaning to do this for a while and finally got round to it :)

Ah, the joys of having a built-in native JavaScript database¹ that can persist and load typed JavaScript objects² and an interactive JavaScript shell (REPL)³ in Kitten⁴ :)

👋🤓 Goodbye Site.js, Hello Kitten!

I started working on creating a Small Web¹ server (a peer-to-peer Web server) six years ago² with Site.js.

Building Site.js was my first attempt. And it resulted in:

• Auto Encrypt (automatic Let’s Encrypt certificates): https://codeberg.org/small-tech/auto-encrypt

• Auto Encrypt Localhost (automatic localhost TLS certificates): https://codeberg.org/small-tech/auto-encrypt-localhost

• @small-tech/https (drop-in Node.js https module replacement with automatic TLS certs everywhere): https://codeberg.org/small-tech/https

• JSDB: In-process, in-memory JavaScript database that persists to append-only JavaScript logs: https://codeberg.org/small-tech/jsdb

As Site.js reached an evolutionary dead-end, and as I learned from my experiements with replicated data types that replicated data types are *not* a prerequisite for a decentralised web (actual topological decentralisation and ease of use are), I started writing a new server/platform called Kitten from scratch while still making use of the tried and tested modules listed above.

Last week, I switched over our last site using Site.js to Kitten and, with that, today I’ve sunset³ Site.js:

https://sitejs.org

For its successor, please see Kitten:

🔒 New Kitten & JSDB Releases

Security fix, JSDB 6.0.1.

This is a critical update.

• JSDB¹ versions 6.0.0 and below suffer from potential data corruption/arbitrary code execution as string keys were not being sanitised in the same way string values were² (so this is relevant to you if you’re storing untrusted data as keys in your data structures in JSDB and/or Kitten databases without carrying out any of your own sanitisation at the application level).

• The latest Kitten release uses JSDB version 6.0.1. Your deployment servers will automatically update in the next few hours. On your development machines, please run `kitten update` in your terminal or use the Update feature in Kitten Settings from your browser.

• If you are using Kitten’s Database App Modules³ feature in your apps, you will have installed JSDB manually and you should update your installation to version 6.0.1.

New Kitten release

• Fixes #236¹: The data preview pages in Kitten’s settings how handle circular references in the deserialised data (which may contain your custom classes if that’s what you were persisting in the database).

https://kitten.small-web.org

💕

PS. Those pages are very rudimentary at the moment and are good for getting quick visual overview of the data you’re persisting. For a fully interactive view, use Kitten’s interactive shell (REPL)² to explore your data until I’ve had a chance to implement a more comprehensive visual interface.

PPS. You persist data in Kitten using the built-in JavaScript Database (JSDB)³ (Or, of course, you can install and use any other database.)

While working on porting the Small Technology Foundation web site¹ to Kitten², I took the opportunity to pull out base Model and Collection classes that I’ll likely end up including in Kitten proper:

• Model: https://codeberg.org/small-tech/site/src/branch/kitten/app_modules/database/Model.js
• Collection: https://codeberg.org/small-tech/site/src/branch/kitten/app_modules/database/Collection.js

To see them in use, here’s the base Posts class (with RSS generation) that extends Collection:
https://codeberg.org/small-tech/site/src/branch/kitten/app_modules/database/Posts.js

And here’s the concrete EventPosts collection class that extends Posts:
https://codeberg.org/small-tech/site/src/branch/kitten/app_modules/database/EventPosts.js

And the EventPost (showing an implementation of a calculated property):
https://codeberg.org/small-tech/site/src/branch/kitten/app_modules/database/EventPost.js

So all this is possible (persisting and reading back typed model collections, etc.) thanks to JSDB¹ (JavaScript database), a zero-dependency, transparent, in-memory, streaming write-on-update JavaScript database I wrote for the Small Web that persists to a JavaScript transaction log and is included as as first-class citizen in Kitten.

https://codeberg.org/small-tech/jsdb

And if you want to know how the magic mapping of classes happens, see the Database App Module:

https://codeberg.org/small-tech/site/src/branch/kitten/app_modules/database/database.js#L34

PS. For a much gentler introduction to persistence in Kitten, see the Kitten Persistence tutorial:
