• 2 i think it should be return this.http.post(this.monUrlObj.monUrl +'/saveNewCategory' + formData).map((res: any) => res.json()); – Lia Commented Sep 25, 2018 at 8:52

I'd advice you to use a string literal. Using `, resulting in `${this.monUrlObj.monUrl}/saveNewCategory`

remove single quotes from 'this.monUrlObj.monUrl'

saveNewCategory(formData){
  return this.http.post(this.monUrlObj.monUrl+'/saveNewCategory',formData).map((res: any) => res.json());
}

Please remove the single quotes and it should work.

return this.http.post(this.monUrlObj.monUrl+'/saveNewCategory',formData).map((res: any) => res.json());
