I\'m starting with node in general, and I\'m attempting to do a site without express. I would none the less want to use ejs to inject my html and this is where my problem is...

Example from some book: template.ejs

<html>
  <head>
    <style type="text/css">
      .entry_title { font-weight: bold; }
      .entry_date { font-style: italic; }
      .entry_body { margin-bottom: 1em; }
    </style>
  </head>
  <body>
    <% entries.map(entry => { %>
      <div class="entry_title"><%= entry.title %></div>
      <div class="entry_date"><%= entry.date %></div>
      <div class="entry_body"><%= entry.body %></div>
    <% }); %>
  </body>
</html>


function blogPage(entries) {
    const values = { entries };
    const template = fs.readFileSync('./template.ejs', 'utf8');
    return ejs.render(template, values);
}


const server = http.createServer((req, res) => {
    const entries = getEntries();
    const output = blogPage(entries);
    res.writeHead(200, {'Content-Type': 'text/html'});
    res.end(output);
    console.log('run server');
});
server.listen(8000);

There is a project called Consolidate.js which provides a common API for many template engines. This ensures they can all be interchangeable. If you want to render templates directly, you want to be compatible with this API.

Sample code from the Consolidate.js README:
```
var cons = require('consolidate');
cons.swig('views/page.html', { user: 'tobi' }, function(err, html){
  if (err) throw err;
  console.log(html); // Or write to your `res` object here
});
```
This sample is for Swig, but similar code works for EJS or any of the compatible engines.

First of all, You need install ejs -> $ npm install ejs --save

Simple example:

main.ejs:

<p> <%= exampleRenderEjs  %> </p>

server.ejs

var ejs = require('ejs');
var fs = require('fs');

var htmlContent = fs.readFileSync(__dirname + '/main.ejs', 'utf8');

var htmlRenderized = ejs.render(htmlContent, {filename: 'main.ejs', exampleRenderEjs: 'Hello World!'});

console.log(htmlRenderized);
