react-filter-by-url

You want to filter a list of items by a URL parameter in a Single Page Application (React):

https://example.com/search?page=2&type=public&status=open

By also call the API with the same parameters:

https://example.com/api/search?page=2&type=public&status=open

The list of items will be filterd automatically by:

• Paste in the link with the URL query parameters
• Change the URL query parameters in the browser
• Select Filter Options in the UI

useFilter

Installation

yarn add react-filter-by-url react-router-dom

We use react-router-dom under the hood, so in the root file index.tsx, wrap the app with <BrowserRouter>:

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App'
import reportWebVitals from './reportWebVitals'
import { BrowserRouter as Router } from 'react-router-dom'

const root = ReactDOM.createRoot(
  document.getElementById('root') as HTMLElement
)

root.render(
  <React.StrictMode>
    <Router>
        <App />
    </Router>
  </React.StrictMode>
)

The hook only requires to pass in a list of params that will be used to display in the browser url and call the API; and the apiUrl.

import { useUrlFilter } from 'react-filter-by-url'

interface ListProps {}

const DemoList: React.FC<ListProps> = ({}) => {
	// api url
	const apiUrl = 'https://rickandmortyapi.com/api/character'

	// list of params to filter
	const params = ['page', 'status']

	const { apiQuery, getDefaultParamValue, handleSelectFilter } = useUrlFilter(
		params,
		apiUrl
	)

	return <></>
}

• apiQuery: API url with the query string
• getDefaultParamValue: get the default value of a param
• handleSelectFilter: handle the select filter event in the UI

Then you can simply call API every time the apiQuery changes which means URL query parameters change.

useEffect(() => {
	fetchApi()
}, [apiQuery])

const fetchApi = async () => {
	const response = await fetch(apiQuery)
	const data = await response.json()
}

Now you can try to change the URL query parameters in the browser or tinker around the filter UI and see the result.
