Causes of "Error: No Default Engine Specified and No Extension Provided"
This error usually occurs when there is a mismatch between the template engine you are using and the file extension of the template file. For example, if you are using the Handlebars template engine, but your template file has a ".ejs" extension, you will get this error. This error can also occur if you have not configured your template engine properly.
Solutions to Fix "Error: No Default Engine Specified and No Extension Provided"
Solution 1: Check the File Extension
The first solution is to check the file extension of your template file. Ensure that the file extension matches the template engine you are using. For example, if you are using the Handlebars template engine, make sure your template file has a ".handlebars" or ".hbs" extension.
Solution 2: Configure Your Template Engine
The second solution is to configure your template engine. If you are using a JavaScript framework like Express, you can configure your template engine in the app.js file. For example, if you are using the Handlebars template engine, you can configure it like this:
app.engine('handlebars', exphbs());
app.set('view engine', 'handlebars');
Solution 3: Install the Required Module
The third solution is to install the required module. Some template engines require specific modules to be installed. For example, if you are using the EJS template engine, you need to install the "ejs" module. You can install it using the following command:
npm install ejs --save
