Types generated by prismicCodegen is empty ( express )

Developing with Prismic
,
1

Hello there
I'm trying to setup prismic with express and typescript
and I want to use prismicCodegen to generate the types

I installed the required packages

{
	"name": "server",
	"version": "1.0.0",
	"type": "module",
	"scripts": {
		"dev": "tsx watch --clear-screen=false root/src/index.ts",
		"build": "tsc",
		"start": "node root/dist/index.ts"
	},
	"dependencies": {
		"@prismicio/client": "^7.11.0",
		"@prismicio/helpers": "^2.3.9",
		"envalid": "^8.0.0",
		"express": "^5.0.1",
		"method-override": "^3.0.0",
		"morgan": "^1.10.0",
		"node-fetch": "^3.3.2",
		"pug": "^3.0.3"
	},
	"devDependencies": {
		"@prismicio/types": "^0.2.9",
		"@types/express": "^5.0.0",
		"@types/method-override": "^0.0.35",
		"@types/morgan": "^1.9.9",
		"@types/node": "^22.8.1",
		"prismic-ts-codegen": "^0.1.22",
		"ts-node": "^10.9.2",
		"tsx": "^4.19.2",
		"typescript": "^5.6.3"
	}
}

prismicCodegen.config.ts

import type { Config } from 'prismic-ts-codegen';

const config: Config = {
	output: './types.generated.ts',
	models: ['./root/src/cms/types/**/index.json'],
};

export default config;

the generated file see to be empty or I'm missing something ?

// Code generated by prismic-ts-codegen. DO NOT EDIT.

import type * as prismic from "@prismicio/client";

type Simplify<T> = { [KeyType in keyof T]: T[KeyType] };

declare module "@prismicio/client" {
	namespace Content {
		export type {
			
		}
	}
}

inside root/src/types I have the following

home.json

{
	"Main": {
		"title": {
			"type": "StructuredText",
			"config": {
				"single": "heading1",
				"label": "title"
			}
		}
	}
}

page.json

{
	"Main": {
		"uid": {
			"type": "UID",
			"config": {
				"label": "uid"
			}
		},
		"title": {
			"type": "StructuredText",
			"config": {
				"single": "heading1",
				"label": "Title"
			}
		}
	}
}

index.json

[
	{
		"id": "home",
		"name": "Home",
		"repeatable": false,
		"value": "home.json"
	},
	{
		"id": "page",
		"name": "Page",
		"repeatable": true,
		"value": "page.json"
	}
]

what I'm missing ?
I already tested that I'm connected to my repo and can see the documents data

I was able to fix the issue after generating a custom type token
do I need to manually regenerate the file every time I add something to my types on prismic ?

Hi @nilenarrator ,

I'll be happy to help but I'm not sure what you mean here. Can you explain what you mean by custom type token?

Thanks.
