Rechercherichtung

Beginne mit dem AngularNodeAppEngine-Einstiegspunkt aus @angular/ssr/node und den im Bericht gezeigten src/package.json-Imports und verfolge anschließend, wie angular.json die Serverausgabe und das Prerendering über src/server.ts aufruft. Überprüfe, dass die Auflösung aus dist und nicht aus src erfolgt, und dass die dokumentierte Einstellung prerender: false das Prerendering verhindert.

Vom Indexierungsmodell aus dem Issue-Text verfasst.

Beschreibung

angular/build:application area: @angular/build area: @angular/ssr freq1: low type: bug/fix

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

ssr

Is this a regression?

Description

when running an angular app that uses AngularNodeAppEngine from "@angular/ssr/node" and outputMode set to server it reads imports from src/package.json which is set to be used in dist

package.json

"imports": {
    "#configs/*": "./browser/configs/*.js"
}

in the source code the configs folder is live in "src/configs" but copied at build time into "dist/browser/configs"
the same goes for many dynamic imports that assume the app runs inside the dist dir, i.e. the paths may be differ from the corresponding paths in the source code.

The prerender should run the same way as the original app runs i.e. from dist.

another thing, I cannot find an option to totally disable the prerendering as prerender: false now has no effect
