Angular - The Complete Guide Section 5 note

 @Input('srvElement') element : {type: string, name: string, content: string};

<app-server-element *ngFor="let serverElement of serverElements"

[srvElement]="serverElement"></app-server-element>

Go the error "ERR_OSSL_EVP_UNSUPPORTED"

  opensslErrorStack: [ 'error:03000086:digital envelope routines::initialization error' ],

  library: 'digital envelope routines',

  reason: 'unsupported',

  code: 'ERR_OSSL_EVP_UNSUPPORTED'

when run "ng serve"

The fix is:

export NODE_OPTIONS=--openssl-legacy-provider
