Error while running `npx convex dev` on mac - No loader is configured for ".node" files: fsevents
This does not seem to solve it - the error stays unchanged. Added convex.json with 
{
  "node": {
    "externalPackages": ["fsevents"]
  }
}
{
  "node": {
    "externalPackages": ["fsevents"]
  }
}
at the same level as my package.json. I've also installed fsevents to be double sure as a dependency, but it's also not making a difference.

Security (ABAC) - written in FSL I love their simple yet powerful ABAC system - in my opinion, the best part of Fauna, because it makes security relatively easy. 
role role_user {
  privileges User {
    read {
      predicate (doc => 
        doc == Query.identity()
      )
    }
    write {
      predicate ((oldDoc, newDoc) => {
        oldDoc.emails == newDoc.emails &&
        oldDoc.accounts == newDoc.accounts &&
        oldDoc == Query.identity()
      })
    }
  }

  privileges createOrganization {
    call {
      //A user can only be part of 5 organizations to prevent organization abuse. 
      // Limit can be lifted if you have a specific use case.
      predicate ((data) => { 
        Query.identity()!.organizations == null || Query.identity()!.organizations.length < 5 
      })
    }
  }


  membership User {
    predicate ( (doc) => isCalledWithAccessToken() )
  }
}
role role_user {
  privileges User {
    read {
      predicate (doc => 
        doc == Query.identity()
      )
    }
    write {
      predicate ((oldDoc, newDoc) => {
        oldDoc.emails == newDoc.emails &&
        oldDoc.accounts == newDoc.accounts &&
        oldDoc == Query.identity()
      })
    }
  }

  privileges createOrganization {
    call {
      //A user can only be part of 5 organizations to prevent organization abuse. 
      // Limit can be lifted if you have a specific use case.
      predicate ((data) => { 
        Query.identity()!.organizations == null || Query.identity()!.organizations.length < 5 
      })
    }
  }


  membership User {
    predicate ( (doc) => isCalledWithAccessToken() )
  }

They had GraphQL support, but they dropped it in favor of their more powerful FQL language, which is inspired by JavaScript, Python, and GraphQL. Collections (Table) Written in a language file called fsl (fauna schema language). I appreciated the co-location of collection constraints, making it easy to understand a collection and its associated rules. 
collection User {
    firstName: String
    ...
    compute emailVerification: String? = doc => { getVerificationEmail(doc.id)} // A field that will be resolved while fetching

    compute roles: Array<String> = (user => currentRoles()) 
    activeOrganization: Ref<Organization>?
    organizations: Array<Ref<Organization>>?

    // A check constraint ensures the created/updated/replaced data comply a specific shape
    check isActiveOrganizationPartOfOrganizations ((user) => {
        if(user.activeOrganization != null) {
            user.organizations?.includes(user.activeOrganization)
        } else {
            true
        }
    })

    check uniqueEmails (user => user.emails.length == user.emails.distinct().length)
    unique [mva(.emails)]
    check uniqueAccounts (user => user.accounts.length == user.accounts.distinct().length)
    unique [mva(.accounts)]
}
collection User {
    firstName: String
    ...
    compute emailVerification: String? = doc => { getVerificationEmail(doc.id)} // A field that will be resolved while fetching

    compute roles: Array<String> = (user => currentRoles()) 
    activeOrganization: Ref<Organization>?
    organizations: Array<Ref<Organization>>?

    // A check constraint ensures the created/updated/replaced data comply a specific shape
    check isActiveOrganizationPartOfOrganizations ((user) => {
        if(user.activeOrganization != null) {
            user.organizations?.includes(user.activeOrganization)
        } else {
            true
        }
    })

    check uniqueEmails (user => user.emails.length == user.emails.distinct().length)
    unique [mva(.emails)]
    check uniqueAccounts (user => user.accounts.length == user.accounts.distinct().length)
    unique [mva(.accounts)]
}
CRUD (Written in FQL - Fauna query language) I liked the short, but powerful syntax. 
// Read
User.byId("123")
User.all()
User.first()

// They make it amazingly easy to filter based on or retrieve related ents
User.all().where((user) => user.activeOrganization.plan == "Pro")
User.first().activeOrganization

// Create
User.create({
  firstName: "John"
})

// Delete
User.byId("123").delete()

// Update & Replace
User.byId("123").update({})
User.byId("123").replace({})

// Projection 
User.first() {
  firstName,
  lastName,
  primaryEmail
}
// Read
User.byId("123")
User.all()
User.first()

// They make it amazingly easy to filter based on or retrieve related ents
User.all().where((user) => user.activeOrganization.plan == "Pro")
User.first().activeOrganization

// Create
User.create({
  firstName: "John"
})

// Delete
User.byId("123").delete()

// Update & Replace
User.byId("123").update({})
User.byId("123").replace({})

// Projection 
User.first() {
  firstName,
  lastName,
  primaryEmail
}

Thanks for sharing—I will check it. The second article about SQL is probably not so relevant to me as I come from Fauna (their service is ending at the end of May—eventually, this is an opportunity for you to get more Fauna customers a new home 😉 ).

Does that mean if I go now with Ents, I can expect some relevant migration later if you ship your own version as part of the convex core?
