We’ll use supabase as the backend service. refine comes with a builtin data provider for supabase thus it’s very easy to create crud pages.



Creating tables

Our app will have these tables in supabase

  • criterias
  • hackathons
  • hackathoners
  • projects
  • projectscores

These are reflected in our app as

export type HackathonerType = {
  id: string;
  name: string;
  team_id: string;
};

export type HackathonType = {
  id: string;
  start: string;
  end: string;
  name: string;
};

export type ProjectType = {
  id: string;
  name: string;
  description: string;
  url: string;
  hackathon_id: string;
  hackathoner_id: string;
};

export type CriteriaType = {
  id: string;
  name: string;
  hackathon_id: string;
};

export type ProjectScoreType = {
  project_id: string;
  criteria_id: string;
  score: string;
};



Craeting CRUD pages

Creating crud pages is as easy like this:

List page:

import {
  List,
  Table,
  useTable,
  Space,
  ShowButton,
  EditButton,
  TextField,
} from "@pankod/refine";

import dayjs from "dayjs";

import { HackathonType } from "interfaces";

export const HackathonsList: React.FC = () => {
  const { tableProps } = useTable<HackathonType>();

  return (
    <List>
      <Table {...tableProps} rowKey="id">
        <Table.Column dataIndex="id" title="ID" />
        <Table.Column dataIndex="name" title="Name" />
        <Table.Column
          dataIndex="start"
          title="Starts"
          render={(value) => (
            <TextField value={dayjs(value).format("DD/MMMM dddd")} />
          )}
        />
        <Table.Column
          dataIndex="end"
          title="Ends"
          render={(value) => (
            <TextField value={dayjs(value).format("DD/MMMM dddd")} />
          )}
        />
        <Table.Column
          title="Actions"
          dataIndex="actions"
          render={(_text, record: HackathonType): React.ReactNode => {
            return (
              <Space>
                <ShowButton size="small" recordItemId={record.id} hideText />
                <EditButton size="small" recordItemId={record.id} hideText />
              </Space>
            );
          }}
        />
      </Table>
    </List>
  );
};

Create page:

import { Create, Form, Input, useForm, DatePicker } from "@pankod/refine";

import { HackathonType } from "interfaces";

export const HackathonsCreate: React.FC = () => {
  const { formProps, saveButtonProps } = useForm<HackathonType>();

  return (
    <Create saveButtonProps={saveButtonProps}>
      <Form {...formProps} layout="vertical">
        <Form.Item label="Name" name="name">
          <Input />
        </Form.Item>
        <Form.Item label="Name" name="start">
          <DatePicker />
        </Form.Item>
        <Form.Item label="Name" name="end">
          <DatePicker />
        </Form.Item>
      </Form>
    </Create>
  );
};

Then use these pages as the corresponding crud component for the hackathon resource:

import { Refine, Resource } from "@pankod/refine";

import "@pankod/refine/dist/styles.min.css";
import { dataProvider } from "@pankod/refine-supabase";
import { supabaseClient } from "utility";
import {
  HackathonsList,
  HackathonsCreate,
  HackathonsEdit,
  HackathonsShow,
} from "./pages/hackathons";

function App() {
  return (
    <Refine
      dataProvider={dataProvider(supabaseClient)}
    >
      <Resource
        name="hackathons"
        list={HackathonsList}
        create={HackathonsCreate}
        edit={HackathonsEdit}
        show={HackathonsShow}
      />
    </Refine>
  );
}

export default App;

refine comes with builtin hooks for Ant design components. You can find detailed usage for the hooks and supabase in the documentation



Creating voting page

We’ll use the dashboard option to place voting page. We’ll need data from different resources. refine comes with powerful hooks that are based on react-query to get data from those resources.

For example to get the hackathons that are active now we can use the useList hook:

export const DashboardPage: React.FC = () => {
  const currentHackathons = useList<HackathonType>({
    resource: "hackathons",
    config: {
      filters: [
        {
          field: "start",
          operator: "lte",
          value: now,
        },
        {
          field: "end",
          operator: "gte",
          value: now,
        },
      ],
    },
  });
}

We can get data from other resources in a similar fashion. You can find the codesandbox here and the repo here



Conclusion

This project itself is a product of a hackathon. It lacks lots of feature like authorization though it shows how refine makes it easy to quickly build a working app.
