How to remove trailing slash in react-router URLs

I start to use react-router in my application and I am noting that when it has a trailing slash at end of URL (/url/) it does not work. I searched more about it, read all documentation and react-router issues and tried to use <Redirect from='/*/' to="/*" />, however it was not a good solution, cause it did not work too. So, reading more I found out a suggestion to insert /?at end of URL, but it still not worked.

The code of routes.js:

export default (
    <Route path="/" component={App}>
        <IndexRoute component={ProfileFillComponents} />
        <Route path="/seguro-residencia" handler={require('./components/Forms/Residencial/ProfileFill/profileFillComponents')} />
        <Route path="/seguro-residencia/informacoes-pessoais" component={CotationNumber} />
    </Route>
)

The code of index.js:

render((<Router history={browserHistory} routes={routes} />), document.getElementById('root'));

Searching more, I found a guy who made a function to force trailing slash at URLs and I resolved to make the opposite of that, forcing to not have it.

Update routes.js code with function No trailing slash function:

export default (
    <Route onEnter={forceTrailingSlash} onChange={forceTrailingSlashOnChange}>
        <Route path="/" component={App}>
            <IndexRoute component={ProfileFillComponents} />
            <Route path="/seguro-residencia" handler={require('./components/Forms/Residencial/ProfileFill/profileFillComponents')} />
            <Route path="/seguro-residencia/informacoes-pessoais" component={CotationNumber} />
        </Route>
    </Route>
)

function forceNoTrailingSlash(nextState, replace) {
  const path = nextState.location.pathname;
  if (path.slice(-1) === '/') {
    replace({
      ...nextState.location,
      pathname: path.slice(1,path.lastIndexOf('/')-1)
    });
  }
}    

function forceNoTrailingSlashOnChange(prevState, nextState, replace) {
  forceNoTrailingSlash(nextState, replace);
}

And again this did not work! I need to make this URLs more friendly as possible and I would like that URLs do not have any trailing slash at the end. Any suggestion how can I make this? And why Redirect did not work in this case?

React Router v6 solution

RemoveTrailingSlash.tsx

import React from "react";
import {Navigate, useLocation} from "react-router-dom";

export const RemoveTrailingSlash = ({...rest}) => {
    const location = useLocation()

    // If the last character of the url is '/'
    if (location.pathname.match('/.*/$')) {
        return <Navigate replace {...rest} to={{
            pathname: location.pathname.replace(/\/+$/, ""),
            search: location.search
        }}/>
    } else return null
}

AppRoutes.tsx

const AppRoutes: React.FC = () => {
    return (
        <React.Fragment>
            <RemoveTrailingSlash/>
            <Routes>
            {/* All your routes go here */}
            </Routes>
        </React.Fragment>
    )
}

I found a good option to make this redirect. Below is the code which I am using:

   app.use(function(req, res, next) {
      if (req.path.length > 1 && /\/$/.test(req.path)) {
        var query = req.url.slice(req.path.length)
        res.redirect(301, req.path.slice(0, -1) + query)
      } else {
        next()
      }
    });

The explanation is basicly it:

In this function, I verify if the URL is grand then one and if it has a trailing slash.
If true, I get this URL without trailing slash and make a 301 redirect to this page without the trailing slash.
Else, I jump to next method to send a value.
