Migrate your build scripts for sexy Angular SSR

If you’re migrating build scripts from an older project into one that uses Angular 17+, you might run into the error:

Project target does not exist.

Why it happens

Angular 17 no longer has a separate build command for SSR! Also, it will complain if you try to use the –production flag.

The fix

In package.json, remove the script with ‘build:ssr’ as the key. It will be located under ‘scripts’:

"scripts": {
  "build:ssr": ".." -- you need to delete this key-value pair
}

Prerendering

As a bonus, Angular will also run the prerender command automatically when it builds. (It’s a setting in angular.json if you want to change it.)
