My goal is to have dynamic og: tags, that can be seen by the facebook crawler. By doing some research I figured the best (and probably the only) approach is to prerender my app on the server. However I'm having problems with doing that.
I already have an existing Node.js server which looks a little different from the servers in most online guides.
const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const http = require('http');
const app = express();
// Api for retrieving data from DB
const api = require('./server/api');
// Parsers
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
// Angular DIST folder
app.use(express.static(path.join(__dirname, 'dist')));
// Api location
app.use('/api', api);
// Send all other requests to the Angular app
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'dist/index.html'))
})
// Set Port
const port = process.env.PORT || '3040';
app.set('port', port);
const server = http.createServer(app)
server.listen(port, () => console.log('Magic happens on localhost:' + port));
I've tried using prerender.io. I got an API key, installed prerender-node and put this right before redirecting the request to index.html:
app.use(require('prerender-node').set('prerenderToken', 'my-token'));
// Send all other requests to the Angular app
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'dist/index.html'))
})
I also added this to my index.html:
<meta name="fragment" content="!">
Nothing changed. Perhaps there's something else I need to do to get it working? Again, my goal is to have dynamic og: tags, that can be seen by the facebook crawler.
Additional info: For now, I'm setting the meta tags using the Meta serivce that comes with Angular 4, if it matters.
