Usable Query: Simplifying React Query Management

🤨 Motivation

The Challenge in Managing Data Fetching in React

While React Query is a powerful tool for managing server state, it can be challenging to work with, especially for developers new to the library or those working on large-scale projects. The syntax for defining and using queries and mutations can be confusing and difficult to read, and the process of setting up and managing server state can be tedious and time-consuming. This can lead to a lot of boilerplate code and make it difficult to maintain and scale React applications.

Introducing UsableQuery

UsableQuery was born out of a need to simplify and streamline the process of working with queries and mutations in React applications. While React Query itself is a powerful tool for managing server state, I recognized that there could be a more intuitive and efficient way to handle these data fetching mechanisms, especially for developers new to the library or those working on large-scale projects.

Goals

Simplify Query Syntax: Provide a more straightforward and readable syntax for defining and using queries and mutations, making it easier for developers of all levels to work with data fetching in React.
Centralize Query Management: Offers a centralized system to manage all queries and mutations, reducing boilerplate and improving maintainability. see this for more details.
Enhance Code Quality: Encourage better coding practices and architecture by providing a structured and consistent way to handle data fetching and state management.
Facilitate Easy Integration and Extensibility: Ensure that UsableQuery seamlessly integrates with existing React Query setups and is flexible enough to adapt to various use cases and requirements.

⬇ Installing usable-query

Important

@tanstack/react-query is a peer dependency of usable-query, so you must install it in your project before installing usable-query.

Using NPM

npm i @tanstack/react-query 

npm i usable-query

Using Yarn

yarn add @tanstack/react-query

yarn add usable-query

Using CDN

<!-- React Query -->
<script src="https://cdn.skypack.dev/@tanstack/react-query"></script>

<!-- Usable Query -->
<script src="https://cdn.skypack.dev/usable-query"></script>

📖 Getting Started

This guide will walk you through the process of installing and implementing UsableQuery in your React project.

Prerequisites

Before you begin, ensure that you have the following installed:

Node.js (version 14 or later)
npm (usually comes with Node.js) or Yarn
A React project set up and ready to go
UsableQuery is built to work alongside React Query, so you should also have @tanstack/react-query installed in your project.

🛠️ Implementation

After installing, you can set up UsableQuery in your project. Here's a basic example to get you started, first we need to setup our base UsableQuery instance:

File: `u-api-query.ts`

import { buildApi } from 'usable-query';
import { QueryClient } from '@tanstack/react-query'; // or your already configured query client


const cacheTime = 1000 * 60 * 60 * 24; // 24 hours

export const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      cacheTime,
      staleTime: cacheTime,
      refetchOnWindowFocus: false,
    },
  },
});


export const baseUQuery = buildApi({
  baseUrl: 'https://jsonplaceholder.typicode.com',
  queryClient,
});

After this we can now use our baseUQuery instance to create our first query or mutation.:

File: `api/user.ts`

import { baseUQuery } from './u-api-query';

type User = {
  id: number;
  name: string;
};

const userUQuery = baseUQuery.createUsableQuery({
  key: 'getUsers',
  endpoints: (builder) => ({
    getUsers: builder.query<null, User[]>({
      key: 'getUsers',
      queryFn: () => ({
        url: '/users',
        method: 'GET',
      }),
    }),
  }),
});

export const { useGetUsersQuery } = userUQuery; // export the generated hook and also the generated query function for server calls

File: `App.tsx`

import { useGetUsersQuery } from './api/user';

function App() {
  const { data, isLoading, error } = useGetUsersQuery();

  if (isLoading) return <div>Loading...</div>;

  if (error) return <div>Oops! Something went wrong...</div>;

  return (
    <div>
      {data?.map((user) => (
        <div key={user.id}>{user.name}</div>
      ))}
    </div>
  );
}

📚 API Documentation

`buildApi`

The buildApi function is used to create a base UsableQuery instance. It takes in an object with the following properties:

Property	Type	Description
`baseUrl`	`string`	The base url for all requests made with this instance.
`queryClient`	`QueryClient`	The query client instance to be used by this instance.
`baseQueryFn`	`BaseQueryFn`	An optional function that can be used to override the default queryFn for all queries created with this instance.
