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.)
