// Create City
router.post('/cities', async (context) => {
    const data = await context.request.body().value
    if (data.slug && data.name) {
        await kv.set(['cities', data.slug], {
            slug: data.slug,
            name: data.name,
            description: data.description
        } satisfies ICity)
    }
})
