Type which translate model to JS type for inertia

[shankiflang]

Hi guys,

I use inertia-react as a frontend and need to pass data from the backend. I was wondering what was the best way to serialize the data before Inertia serializes it in its own way. I currently have a toJSON() on each of my models that translate. I don't know if it's possible to create a type that reads the model and creates a type that can be passed to Inertia. I'm trying to find a way of automating this operation, as I don't want to multiply the definitions of the same resource.

Example of my model :

import string from '@adonisjs/core/helpers/string'
import { BaseModel, beforeSave, column } from '@adonisjs/lucid/orm'
import { DateTime } from 'luxon'
import { type UUID } from 'node:crypto'

export default class Blockchain extends BaseModel {
  @column({ isPrimary: true })
  declare id: UUID

  @column()
  declare name: string

  @column()
  declare slug: string

  @column()
  declare ticker: string

  @column()
  declare explorer: string

  @column()
  declare regexToken: string

  @column.dateTime({ autoCreate: true })
  declare createdAt: DateTime

  @column.dateTime({ autoCreate: true, autoUpdate: true })
  declare updatedAt: DateTime

  @beforeSave()
  public static async createSlug(blockchain: Blockchain) {
    if (blockchain.$dirty.name) {
      let baseSlug = string.slug(blockchain.name, { lower: true, strict: true })
      let slug = baseSlug

      let count = 1
      while (await Blockchain.findBy('slug', slug)) {
        slug = `${baseSlug}-${count}`
        count++
      }

      blockchain.slug = slug
    }
  }

  toJSON() {
    return this.serialize() as {
      id: string
      name: string
      slug: string
      ticker: string
      explorer: string
      regexToken: string
      createdAt: string
      updatedAt: string
    }
  }
}

If anyone has a better approach, I'd love to hear about it!
