Struggling with HTTP Module in Angular

Angular
11

Very useful post. Thank you.

Today the url works properly with https only and createPost method seems to be fine this way:

  createPost(input: HTMLInputElement) { 
    input.value = "";

    this.http.post(this.url, post)
      .subscribe(response => {
        post['id'] = response?.['id'];
        this.posts.splice(0, 0, post); 
      });
  }

After error handling:

  createPost(input: HTMLInputElement) {
    let post: any = { title: input.value };
    input.value = '';                   

    this.service.createPost(post)
      .subscribe({
        next: (response) => {
          post['id'] = response?.['id'];
          this.posts.splice(0, 0, post);
        },
        error: (error: Response) => {
          if (error.status === 400) {
            //this.form.setErrors(error);
          }
          else {
            alert('An unexpected error occured.');
            console.log(error);
          }
        }
      });
  }

Actually this post is pretty useful about the error handling section:
