About this ebook

This book learns about developing web services based on REST architecture using Deno. Deno is the latest server runtime environment for typescript and javascript in addition to node.js which is well known to date. Yes, deno was created by Ryan Dahl who created node.js itself, will deno be the next node.js successor? Of course there are reasons behind developing a new runtime for executing typescript and javascript.

Architecturally, for deno runtime javascript it still uses Google Engine V8 just like the previous node.js, but this time the deno was built using Rust and TypeScript languages, while node.js was built with C ++ and JavaScript. For asynchronous runtime and event driven deno use the open source library, Tokio. Deno support typescript built-in or out of the box in the sense can be used directly without having to first configure settings, unlike node.js. The use of javascript is also supported in addition to typescript. Deno is more secure than node.js, because by default deno cannot access files, environment access, network, without explicit declaration.

What is discussed in this book? Here are the points:

- Introduction and installation of deno along with visual studio code as a code editor

- Use standard modules for http servers

- Use of third party modules such as oak to handle requests, responses, and routing

- Creating a controller and routing for CRUD functionality for the postgresql database

- Using Denon to automate the compilation and deno project running

- Implementation of middleware for authentication

- Implement bcrypt module for password hashing

- Implementation of authentication using JWT

- Implementation of https server

- Refactoring module

- Repository pattern

- Access user defined functions and stored procedures in postgresql

- Bundling project

- The use of PM2 as monitoring tools

- The use of denoDB ORM

Hopefully this book can be another alternative as a source of learning exercises, tutorials, or references for those who want to learn Deno programming.
