node.js - I would like to be able to include EJS template data into a partial view and have it render on all pages the partial is called

Question

I am working on layouts and templating. I have a site where I have files "views/partials/header.ejs" and "views/partial/footer.ejs". I have the app.js file with templating set up as follows:

const express = require('express')
const bodyParser = require('body-parser');
const nodemailer = require('nodemailer');
const ejs = require('ejs');
const date = require(__dirname + '/date.js');

const app = express();

app.set('view engine', 'ejs');

app.use(bodyParser.urlencoded({extended: true}));
app.use(express.static("public"));


app.get('/', function(req, res) {

  const year = date.getYear();

  res.render('home', {copyrightYear: year})
});



app.listen(3000, function() {
  console.log('Server started on port 3000');
});

What I need to do is pass the const copyrightYear into the partial "footer" instead of having to to input into each route. Any advice would be welcomed.

Thanks in advance.

Answer 1

you can't do that because when you make a request the server get the required file the does the logic on it and then it send it back to the browser .

so when you use this

app.get('/', function(req, res) {

  const year = date.getYear();

  res.render('home', {copyrightYear: year})
});

the server will get the home file which includes the partials files then pass the data then send it to the browser .

so you must make separate request for each file you want and then do the logic on it
