Configure Express to send index.html for every url EXCEPT those ending in .css and .js

Question

I\'m new to Express and I\'m trying to set up a SPA where every url is handled by index.html (Backbone).

I want every url to send down index.html, except /bundle.js

Answer 1

I managed to solve it this way:

const getExtension = fileName => (
  fileName.substr(fileName.lastIndexOf('.') + 1)
)

app.get('*', ({ url }, res) => {
  let filePath
  if (['js', 'css', 'png', 'jpg'].includes(getExtension(url))) {
    filePath = __dirname + '/public/' + url
  } else {
    filePath = __dirname + '/public/' + url + '/index.html'
  }
  res.sendFile(filePath)
});
