What is Multitenancy?​

Multitenancy refers to a kind of architecture where a single instance of software runs on a server and serves multiple customers. In a multi-tenant environment, separate customers tap into the same hardware and data storage, creating a dedicated instance for each customer. Each tenant’s data is isolated and remains invisible to others, but is running on the same server.

Introduction​​

In this guide, we will create an application with you in the logic of Multi Tenant(Multitenancy). We can say multi tenant application is separate and manage multiple contents independently from each other in a single application.

We will make a Cake House application using refine and Strapi-v4. Our Cake House will consist of two separate stores and there will be special products for these stores. We will explain step by step how to manage these stores, products, and orders separately.

CAUTION

This guide has been prepared to assume you know the basics of refine. If you haven't learned these basics yet, we recommend reading the Tutorial.

Setup​

npm i @pankod/refine-strapi-v4
CAUTION

To make this example more visual, we used the @pankod/refine-antd package. If you are using Refine headless, you need to provide the components, hooks, or helpers imported from the @pankod/refine-antd package.

Usage​

AuthProvider​

Show Code

src/authProvider.ts
import { AuthProvider } from "@pankod/refine-core";
import { AuthHelper } from "@pankod/refine-strapi-v4";
import axios from "axios";

export const axiosInstance = axios.create();

const API_URL = "YOUR_API_URL";
const TOKEN_KEY = "strapi-jwt-token";
const strapiAuthHelper = AuthHelper(API_URL + "/api");

export const authProvider: AuthProvider = {
    login: async ({ username, password }) => {
        const { data, status } = await strapiAuthHelper.login(
            username,
            password,
        );
        if (status === 200) {
            localStorage.setItem(TOKEN_KEY, data.jwt);

            // set header axios instance
            axiosInstance.defaults.headers.common["Authorization"] = `Bearer ${data.jwt}`;
            return Promise.resolve();
        }
        return Promise.reject();
    },
    logout: () => {
        localStorage.removeItem(TOKEN_KEY);
        return Promise.resolve();
    },
    checkError: () => Promise.resolve(),
    checkAuth: () => {
        const token = localStorage.getItem(TOKEN_KEY);
        if (token) {
            axiosInstance.defaults.headers.common["Authorization"] = `Bearer ${token}`,
            return Promise.resolve();
        }

        return Promise.reject();
    },
    getPermissions: () => Promise.resolve(),
    getUserIdentity: async () => {
        const token = localStorage.getItem(TOKEN_KEY);
        if (!token) {
            return Promise.reject();
        }

        const { data, status } = await strapiAuthHelper.me(token);
        if (status === 200) {
            const { id, username, email } = data;
            return Promise.resolve({
                id,
                username,
                email,
            });
        }

        return Promise.reject();
    },
};

TIP

If you need the population for the /me request, you can use it like this in your authProvider.

const strapiAuthHelper = AuthHelper(API_URL + "/api");

strapiAuthHelper.me("token", {
  metaData: {
    populate: ["role"],
  },
});
App.tsx
import { Refine } from "@pankod/refine-core";
import {
  Layout,
  ReadyPage,
  useNotificationProvider,
  ErrorComponent,
} from "@pankod/refine-antd";
import { DataProvider } from "@pankod/refine-strapi-v4";
import routerProvider from "@pankod/refine-react-router-v6";

import "@pankod/refine-antd/dist/reset.css";

import { authProvider, axiosInstance } from "./authProvider";

const API_URL = "YOUR_API_URL";

const App: React.FC = () => {
  return (
    <Refine
      authProvider={authProvider}
      dataProvider={DataProvider(API_URL + "/api", axiosInstance)}
      routerProvider={routerProvider}
      Layout={Layout}
      ReadyPage={ReadyPage}
      notificationProvider={useNotificationProvider}
      catchAll={<ErrorComponent />}
    />
  );
};
TIP

You can find detailed usage information and the source code here.

Create Collections​

We created three collections on Strapi as store, product, and order and added a relation between them. For detailed information on how to create a collection, you can check here.

Stores

  • Title: Text
  • Relation with Products
  • Relation with Orders
stores

Products

  • Title: Text
  • Description: Text
  • Image: Media
  • Relation with Stores
  • Relation with Orders
products

Orders

  • Status: Text
  • Customer Name: Text
  • Customer Address: Text
  • Quantity: Number
  • Relation with Stores
  • Relation with Product
orders

Now that we have completed the setup and our collections, we can now log in with the refine and start the listing processes.

Store Context​

To view the products and orders of two different stores separately, we need to filter by storeId. We will use the storeId information in more than one place. For example, when creating a store-specific order.

For this reason, we will create a React Context and keep the storeId state information in it and send it to the relevant refine components.

src/contexts/StoreContext.tsx
import { createContext, useState } from "react";

export const StoreContext = createContext<any[]>([]);

export const StoreProvider = (props: any) => {
  const [store, setStore] = useState(1);

  return <StoreContext.Provider value={[store, setStore]} {...props} />;
};
App.tsx
import { Refine } from "@pankod/refine-core";
import {
  Layout,
  ReadyPage,
  useNotificationProvider,
  ErrorComponent,
} from "@pankod/refine-antd";
import { DataProvider } from "@pankod/refine-strapi-v4";
import routerProvider from "@pankod/refine-react-router-v6";

import "@pankod/refine-antd/dist/reset.css";

import { StoreProvider } from "context/store";
import { authProvider, axiosInstance } from "./authProvider";

const API_URL = "YOUR_API_URL";

const App: React.FC = () => {
  return (
    <StoreProvider>
      <Refine
        authProvider={authProvider}
        dataProvider={DataProvider(API_URL + "/api", axiosInstance)}
        routerProvider={routerProvider}
        Layout={Layout}
        ReadyPage={ReadyPage}
        notificationProvider={useNotificationProvider}
        catchAll={<ErrorComponent />}
      />
    </StoreProvider>
  );
};

Shop Select to Sider Component​

We will create a select component in the Sider Menu where the user will select the stores. Let's create our select component first, then let's see how we can define it in the refine Sider.

scr/components/select/StoreSelect.tsx
import { useContext } from "react";
import { Select, useSelect } from "@pankod/refine-antd";

import { StoreContext } from "context/store";
import { IStore } from "interfaces";

type SelectProps = {
  onSelect: () => void;
};

export const StoreSelect: React.FC<SelectProps> = ({ onSelect }) => {
  const [store, setStore] = useContext(StoreContext);

  const { selectProps: storeSelectProps } = useSelect<IStore>({
    resource: "stores",
    optionLabel: "title",
    optionValue: "id",
  });

  const handleChange = (selectedValue: string) => {
    setStore(selectedValue);
  };

  return (
    <Select
      defaultValue={store}
      style={{ width: 130 }}
      onChange={handleChange}
      onSelect={onSelect}
    >
      {storeSelectProps.options?.map(({ value, label }) => (
        <Select.Option key={value} value={value}>
          {label}
        </Select.Option>
      ))}
    </Select>
  );
};

Here we have created a select component. Then we fetch the store id and title we created in the Strapi database with useSelect. Now we can place the store information we have in the state we created in the Store Context.

Let's define the select component in the refine Sider Menu. First, we need to customize the default Sider.

src/components/sider/CustomSider.tsx
import React, { useState } from "react";
import {

    return tree.map((item: ITreeMenu) => {
      const { icon, label, route, name, children, parentName } = item;

      if (children.length > 0) {
        return (
          <SubMenu
            key={route}
            icon={icon ?? <Icons.UnorderedListOutlined />}
            title={label}
          >
            {renderTreeView(children, selectedKey)}
          </SubMenu>
        );
      }
      const isSelected = route === selectedKey;
      const isRoute = !(parentName !== undefined && children.length === 0);
      return (
        <CanAccess key={route} resource={name.toLowerCase()} action="list">
          <Menu.Item
            key={route}
            style={{
              fontWeight: isSelected ? "bold" : "normal",
            }}
            icon={icon ?? (isRoute && <Icons.UnorderedListOutlined />)}
          >
            <Link to={route}>{label}</Link>
            {!collapsed && isSelected && (
              <div className="ant-menu-tree-arrow" />
            )}
          </Menu.Item>
        </CanAccess>
      );
    });
  };

  return (
    <AntdLayout.Sider
      collapsible
      collapsedWidth={isMobile ? 0 : 80}
      collapsed={collapsed}
      breakpoint="lg"
      onCollapse={(collapsed: boolean): void => setCollapsed(collapsed)}
      style={isMobile ? antLayoutSiderMobile : antLayoutSider}
    >
      {Title && <Title collapsed={collapsed} />}
      <Menu
        selectedKeys={[selectedKey]}
        mode="inline"
        onClick={() => {
          if (!breakpoint.lg) {
            setCollapsed(true);
          }
        }}
      >
        <Menu.Item key={route} icon={<Icons.AppstoreAddOutlined />}>
          <StoreSelect
            onSelect={() => {
              setCollapsed(true);
            }}
          />
        </Menu.Item>
        {renderTreeView(menuItems, selectedKey)}
        <Menu.Item
          key="logout"
          onClick={() => logout()}
          icon={<Icons.LoginOutlined />}
        >
          Logout
        </Menu.Item>
      </Menu>
    </AntdLayout.Sider>
  );
};

sider
As you can see, you can now choose the store you want and create products and orders specifically for the store we have chosen according to the storeId information.

Product List Page​

Now we can list the products of the selected store according to the storeId information by filtering it. We can do this filtering by using the permanetFilter property within the refine's useSimpleList hook.

We separate the products of different stores by using the permanentFilter with the storeId we get from the Store Context. So we can control more than single content in one application.

const [store] = useContext(StoreContext);
const { listProps } = useSimpleList<IProduct>({
  permanentFilter: [{ field: "stores][id]", operator: "eq", value: store }],
});
Show Code

src/pages/ProductList.tsx
import { useContext } from "react";
import { IResourceComponentsProps, HttpError } from "@pankod/refine-core";
import {
  useSimpleList,
  AntdList,
  useModalForm,
  useDrawerForm,
  CreateButton,
  List,
} from "@pankod/refine-antd";

import { IProduct } from "interfaces";

import { ProductItem } from "components/product";
import { StoreContext } from "context/store";

export const ProductList: React.FC<IResourceComponentsProps> = () => {
  const [store] = useContext(StoreContext);
  const { listProps } = useSimpleList<IProduct>({
    permanentFilter: [{ field: "stores][id]", operator: "eq", value: store }],
    metaData: { populate: ["image"] },
  });

  return (
    <List
      headerProps={{
        extra: <CreateButton onClick={() => createShow()} />,
      }}
    >
      <AntdList
        grid={{ gutter: 16, xs: 1 }}
        style={{
          justifyContent: "center",
        }}
        {...listProps}
        renderItem={(item) => (
          <AntdList.Item>
            <ProductItem item={item} editShow={editShow} />
          </AntdList.Item>
        )}
      />
    </List>
  );
};

Store Filter

Product Create Page​

Now let's see how we can create store-specific products. Which store we choose in Sider, the product we will create will automatically be the product of the selected store.

By overriding the onFinish method of the form and sending the selected store information, we specify which store it will be the product of.

const [store, setStore] = useContext(StoreContext);

<Form
    {...formProps}
    ...
    onFinish={(values) => {
        return (
            formProps.onFinish?.({
                ...values,
                stores: store,
            })
        );
    }}

Conclusion​

In this guide and our example app, we talked about how we can build Multitenancy apps with refine. Developing a Multitenancy application with refine is quite simple. By creating a context and with the hooks that refine provides, you can quickly and easily produce similar applications in this logic.
