Redirect all trailing slashes globally in express

Question

I am using Node.js and Express and I have the following routing :

app.get(\'/\', function(req,res){
    locals.date = new Date().toLocaleDateString();

    r         


        

Answer 1

I'm adding this answer because I had too many issues with other solutions.

/**
 * @param {express.Request} req
 * @param {express.Response} res
 * @param {express.NextFunction} next
 * @return {void}
 */
function checkTrailingSlash(req, res, next) {
  const trailingSlashUrl = req.baseUrl + req.url;
  if (req.originalUrl !== trailingSlashUrl) {
    res.redirect(301, trailingSlashUrl);
  } else {
    next();
  }
}

router.use(checkTrailingSlash);

This will translate:

/page ==> /page/
/page?query=value ==> /page/?query=value
