Codesandbox playground link:

https://codesandbox.io/s/nodejs-template-engine-md1hb

Features:

• Light weight
• Has it's own parsing template literal: $nv{}
• We can pass objects through the routes like so:

  if (req.url === '/') {
      httpStaticCall.serve(req, res, {
          uri: req.url,
          method: req.method,
          host: req.headers.host,
          remoteAddress: req.connection.remoteAddress
      });
  }

• Then we can use and access those objects by using our template literal $nv{} like so:

  <div>
      <h3>Dynamic Object Variables Processed By Template Engine:</h3>
      <span>
          <span>Request URI: $nv{uri}</span><br/>
          <span>Request Method: $nv{method}</span><br/>
          <span>Request Host: $nv{host}</span><br/>
          <span>Request Remote Host: $nv{remoteAddress}</span><br/><br/>
      </span>
  </div>

Install required node modules:

npm install

How to run the code?

First, start the server:

npm start

Test the template engine:

• Open http://localhost on any browser of your choice.
• You will see an web page which contains Request URI, Request Method, Request Host, Request Remote Host variables
• Those variables are rendered by our template engine which parses by $nv{} template literal
• Click on the "Form post to mongodb test" link or open http://localhost/get-form-test.html
• You will see a form with Msg id and Msg field

User Inputs / Outputs:

Input:

• Put any random id and random message into the form and click on "Submit" button
• It will post the form data through the api
• You will get back json response from the api on successful insertion of documet to mongodb collection
• The JSON response uses template our custon engine to render it to browser

Output:

JSON Response like this:

  [{"_id":"61c1d8b039e9a2004a1771b6","test-msg-id":"d456","test-msg":"User data"}]
