Vue Router history mode with Express and nginx reverse proxy

Question

I have configured nginx to pass all requests to Node:

server {
    listen 80;
    server_name domain.tld;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

On the server I have a Node app running Express which servers my Vue index file.

app.get('/', (req, res) => {
  res.sendFile(`${__dirname}/app/index.html`);
});

I want to use HTML5 history mode with Vue router, so I set mode: 'history' in the router settings. I installed connect-history-api-fallback and set it up:

const history = require('connect-history-api-fallback');
app.use(history());

The routes works fine if the user first hits http://domain.tld . But, if a subroute is accessed directly, or the page is refreshed, I get a not found error.

How do I change my configuration?

Answer 1

As I couldn't get the connect-history-api-fallback library working, I created one myself:

app.use((req, res, next) => {
  if (!req.originalUrl.includes('/dist/', 0)) {
    res.sendFile(`${__dirname}/app/index.html`);
  } else {
    next();
  }
});

This will send the /app/index.html when requested anything but /dist where scripts and images are located.

Answer 2

I had the same problem.

It won't work when the order is:

app.use(express.static('web'));
app.use(history());

,but will work when:

app.use(history());
app.use(express.static('web'));

Whole example app:

var express = require('express');
var history = require('connect-history-api-fallback');
var app = express();

app.use(history());
app.use(express.static('web'));

app.listen(3002, function () {
    console.log('Example app listening on port 3002!')
});

In web folder i have:
index.html
and other js, css files.
