Which @angular/* package(s) are the source of the bug?

platform-server

Is this a regression?

No

Description

ngModule version

I clone the Angular Universal repo version from angular:

• checkout master then: pnpm install
• pnpm dev:ssr to serve
• nodemon --inspect=localhost:9236 dist/server/main.js to inspect

Then I start it and make a heap snapshot. it’s fine. Open dev tools for Node.js to inspect, Go to memory tab, search module keyword

first-time load home page: load home page at second time:

load home page at 20th times:

everything is fine and no leak. NgModule only have 2 instance

Standalone version

I upgrade the universal version of the standalone component, I’m going to make this on the universal repo, but first, it has a memory leak.

• checkout master then: pnpm install
• pnpm dev:ssr to serve
• nodemon --inspect=localhost:9236 dist/server/main.js to inspect

go home page and f5 for 6 times:

go home page and f5 for more 5 times:

we get too many modules that are not clear and the heap memory goes “To infinity and beyond”. The ApplicationModule goes to x6 on 6 load pages, and x11 if you have 11 load pages.
