Pug template issue in Tsed 8

[jkokh]

Describe the bug

I'm struggling with migrating from Ts.ED 7 to Ts.ED 8.
The issue is I'm getting this error when configuring Pug template engine:

event: 'PLATFORM_VIEWS_ERROR',
message: 'Unable to configure the PlatformViews service on your environment.',
error: TypeError: Cannot read properties of undefined (reading 'render')
    at file:///Users/evgeny/Projects/orig/node_modules/@tsed/platform-express/lib/esm/components/PlatformExpress.js:174:54

Views config

views: {
  root: join(process.cwd(), "src/views"),
  viewEngine: "pug",
  extensions: {
    pug: 'pug'
  }
}

---

What I’ve checked:

• pug is installed in node_modules
• View files exist in the correct location (src/views)
• @tsed/platform-express is correctly imported and loaded
• Code worked fine on Ts.ED v7
• Running in ESM mode with swc-node

---

Expected behavior

I expect .pug templates to be rendered using the @View() decorator or res.render(...), like:

@View("home.pug")
@Get("/")
get() {
  return { message: "Hello from Pug!" };
}

To Reproduce

1. Create a new Ts.ED 8 project
2. Install pug: npm install pug
3. Configure views in Server.ts:

   views: {
     root: join(process.cwd(), "src/views"),
     viewEngine: "pug",
     extensions: { pug: "pug" }
   }
   

Expected behavior

Pug templates render

Hi @jkokh

Since v8.11 + you have to import the template engine like that in your server.ts:

import {Configuration} from "@tsed/di";
import "@tsed/engines/PugEngine.js"; // import Nunjucks engine
import pug from "pug";

You'll find all details here: https://tsed.dev/docs/templating.html#usage

See you

[jkokh]

import "@tsed/engines/PugEngine.js";

Thanks a lot!

I’ll add a note over this change on the v8 migration page
