研究方向

從 @angular/ssr/node 中的 AngularNodeAppEngine 進入點和報告中顯示的 src/package.json 匯入開始，接著追蹤 angular.json 如何透過 src/server.ts 呼叫伺服器輸出和 prerendering。確認解析是從 dist 而不是 src 進行，並確認文件所述的 prerender: false 設定會防止 prerendering。

描述

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
