🎉 Got database backup and restore working in Kitten (so every Kitten app gets it for free) and, with the new JSDB 5 support in Kitten, you can now make your model classes EventEmitters.

The session object is now an EventEmitter so you can now listen for events on the current session. In fact, I did just that in Kitten itself to implement the upload of the backup file during the restore process to make the Streaming HTML handler get notified once the POST route has the upload.

Code listing of restore.post.js in Helix Editor:

/**
Receives a backup of Kitten databases to restore.
*/
export default function ({ request }) {
// The event is broadcast on the session id.
request.session.emit('databasesUploadedForRestore', request.uploads[0])
}

Code listing (detail) of index.page.js in Helix Editor:

const RestoreStatusUpdate = ({SLOT}) => kitten.html`
<div id='restore-status' class='progress'>
<${ProgressIndicator} />
${SLOT}
</div>
`

export function onConnect ({request, page}) {
page.on('startRestore', () => {
page.send(kitten.html`<${RestoreStatusUpdate}>Uploading backup to restore from…</>`)
})

const restoreDatabases = async (/** @type {Upload} */ upload) => {
console.log('Restore: database backup uploaded', upload)

// Show status indicator.
page.send(kitten.html`<${RestoreStatusUpdate}>Restoring from backup…</>`)

// Delete current databases.
const deleteResult = await fs.rm(kitten.databaseDirectory, {recursive: true, force: true})

// Re-create databases directory.
const makeDirectoryResult = await fs.mkdir(kitten.databaseDirectory)

// Decompress backed-up databases.
await extract({
cwd: kitten.databaseDirectory,
file: upload.filePath
})

// Send refresh header and restart the server so the
// restored databases are loaded into memory.
page.send(kitten.html`<${RestoreStatusUpdate}>Restore complete, waiting for server restart…`)

// Restart the server.
process.exit(99 /* code for restart request */)
}
request.session.removeListener('databasesUploadedForRestore', restoreDatabases)
request.session.addListener('databasesUploadedForRestore', restoreDatabases)

I wanted to give it a try but didn't have enough time. The keybindings appear promising, but might take some time to get used to.

As someone who's really into dark themes, I gotta say, this light theme is really pleasing.

@triskelion Yeah, I have things set up so the terminal theme changes with the system theme using a little tool I wrote called Lipstick on a Pig:

(I don’t remember which light theme I ended up with but can look it up for you and let you know next time I’m at my desk if you like.) :)

Lipstick on a Pig: learning the most important lesson in design

I just released a little tool called Lipstick on a Pig that helps keep the visual appearance of supported command-line applications in sync with the current light/dark mode setting (colour scheme) of your system in GNOME.
