Get current route for react-router

Question

How can I get the current route? And I mean route , not path

After entering manually an url, in the root component of my app App.tsx I want to get some options from the url

I tried this:

    const match = useRouteMatch({
        path: location.pathname,
        strict: true,
        sensitive: true
    });

But it doesn't give me the props.

So I need something like:

    const match = useRouteMatch({
        path: `/:lang/:car`,
        strict: true,
        sensitive: true
    });

But I need to get that path(route) somehow dynamically.

I also tried to use useParams from react-router-dom . And do something like:

const { lang } = useParams<ParamTypes>();

This also doesn't work if I write it in the main component App.tsx . Only in a component that specifically has /:lang in it's route.

If this wasn't clear I'll put an example.

Let's say I have these routes:

<Route path='/'/>
<Route path='/:lang'/>
<Route path='/:lang/:bookId'/>
<Route path='/:lang/:bookId/:author'/>

And I enter manually the url baseurl/en/21

In App.tsx how can I get the lang and the bookId?

I should have something like:

    const match = useRouteMatch({
        path: `/:lang/:bookId`,
        strict: true,
        sensitive: true
    });

But say I enter the url baseurl/en/21/some-name , then the match const will be null. And in this case I also would want to get author . However I don't know what url will the user be typing. So this is why I need to get the route dynamically.

Answer 1

Try this:

  const findPath() {
    const location = useLocation();
    useEffect(() => {
      const currentPath = location.pathname;
    }, [location]);
    return currentPath;
  }

This will return the entire path by using the useLocation hook and it will re-render every time the url is changed because of the useEffect.

try this hook:

import { useEffect, useState } from "react";
import { useLocation } from "react-router-dom";

export const useFindPath = () => {
    const location = useLocation();
    const [currentPath, setCurrentPath] = useState();
    useEffect(() => {
        setCurrentPath(location.pathname);
    }, [location]);
    return currentPath;
};

usage:

const path = useFindPath();

returns "/about" if I'm on about page

Here's my React Code written in TS to get a split pathname:

import { useEffect, useState } from 'react';
import { useLocation } from 'react-router-dom';

/**
 * @function useFindPath
 * @param pathIdx
 * @description - returns a string from the current route based on the path split by `/`.
 * @returns string
 * @example:
 *   - pathIdx = 2
 *   - path = /projects/foo-bar
 *   - return = 'foo-bar'
 */
export const useFindPath = (pathIdx?: number): string => {
  const location = useLocation();
  const [currentPath, setCurrentPath] = useState<string>();

  useEffect(() => {
    const path: string = location.pathname;

    if (pathIdx) {
      const splitPath: string[] = location.pathname.split('/');

      setCurrentPath(splitPath[pathIdx]);
    } else {
      setCurrentPath(path);
    }
  }, [location, pathIdx]);

  return currentPath as string;
};
