2. Added API call for fetching data

pagination.component.ts

  apiRoute: string = `http://localhost:4000/api/students`;
  
  // Fetch new page data
  next() {
    this.getData(this.currentPageNumber + 1)
  }
  
  // Fetch previous page data
  prev() {
    this.getData(this.currentPageNumber - 1)
  }

  // Fetch data from API
  getData(pageNo: any) {
    this.currentPageNumber = Number(pageNo);
    let finalPath = `${this.apiRoute}?pageNumber=${this.currentPageNumber}&recordsPerPage=5`;

    this.http.get(finalPath).subscribe(
      (response: any) => {
        console.log('Total records count:', response.count)
        console.log('Response data:', response.data)
      },
      (error) => {
        console.log(error.message);
      }
    );
  }
