EJS VS Koa

Templating language - ejs

Its Github repository is https://github.com/mde/ejs and it Complies with the Express view system but along with pros there are some cons of EJS like it is very difficult to read its code, especially for designers and HTML people who don't focus on Backend languages and one more con is that it has no support for block by default.

With our Yugabyte database setup, let’s install the dependencies for our application. Install typeorm,pg, and ejs with the command below:

We need a frontend client to interact with authorization server. For this purpose we are going to use koa and EJS in combination. EJS is a template engine. It gives us the ability to write HTML files with more flexibility.

You can use striate, a superset of ejs, to control which code gets generated within the files. The answers given to the prompts in yogini.json are available as variables within the scope of your template files.

Since "Express.js is an old framework that has not evolved for a long time. It's not a good choice for new projects since it can easily lead to security issues and memory leaks." -- H3. Which is also the case for Koa.

In this example, we're using the serverless framework to quickly set up the Lambda function along with an API gateway for the entry point. The lambda function is a simple Koa REST API with a few functional endpoints.

The initial step is to create our entry point, from where the page will be rendered. In this case, we will use the koa framework.

Koa.js: By the team behind Express, Koa.js utilized async/await for middleware, resulting in cleaner and more readable code.

Koa -Next Generation Node Microservice Framework

Backend is more tricky. - RESTful APIs I prefer Koajs - For a RPC/microsevice, I have only used gRPC - For a CLI, yargs and inquirer

There are lot of different frameworks out there. If you learn one, there is no guarantee that the next job you find will use the same. For example if you learn Express and the next one used Koa or Nest.

Koa.js is a minimal and flexible Node.js web application infrastruc­ture, which provides a robust set of features for web and mobile applica­tions. It is an open-source framework developed and maintained by the creators of Express.js, the most popular web framework for Node.js.
