如何更改此功能以仅在express上给我项目文件夹路径？（__ dirpath）

Question

app.use(function(req, res) {
   res.sendFile(__dirname + '/views/404.html');
});

The current fucntion is giving me this path ...\\Ex1\\server\\views\\404.html how can i change the function to give me this path Ex1\\views\\404.html and send the html file.

Answer 1

app.use(function(req, res) {
  const path = require('path');
  const fpath = path.normalize(__dirname + "/..");
  res.sendFile(fpath + '/views/404.html');
});

To resolve my problem i had to get the "path" module https://nodejs.org/docs/latest/api/path.html and use the path.normalize method.

path.normalize(__dirname + "/..");

where __dirname is "\\Ex1\\server"

Using __dirname + "/.." in path.normalize it will return only the Ex1 then i added "/views/404.html" to return the file i pretended.
