creates a pagination object (useful to format the result of a DB query)

pagination.js

export const pagination = (paginationParams = {}) => ({
  ...paginationParams,
  limit: paginationParams.limit || 20,
  offset: paginationParams.offset || 0,
  totalCount: paginationParams.totalCount || 0,
  get currentPage() {
    return Math.floor(this.offset / this.limit) + 1;
  },
  get hasNext() {
    return this.currentPage * this.limit < this.totalCount;
  },
  get hasPrevious() {
    return !!this.offset;
  },
  get totalPage() {
    if (!this.totalCount) {
      return 1;
    }
    return Math.ceil(this.totalCount / this.limit);
  },
});
