Backend Developer & Development [ Part 1 ]



Backend developer is a develop who maintain the work users /  clients can't see such as processing transaction, data structure, data transfer. These works would contains in a API server and API server contains many endpoint that can call by anyone but only success when fulfill endpoint requirements so it is secured.

API Server

also know as REST API ( Representational State Transfer ). It's processing like client request to server & after server process return response to client.
API Server is develop by backend developer and this api server can be many type and different language, different framework such as
  • Ruby on Rails ( RoR ) using Ruby
  • Python
  • PHP ( Laravel & Yii2 )
  • Java ( Spring )
  • C# ( ASP.NET & NancyFX )
  • Node.JS ( ExpressJS, SailsJS, HapiJS, NestJS, FeatherJS )
Different framework have their own advantages and can be used on different projects based on their features and usage. In the development not only choosing frameworks also need to choose ORM / ODM for managing objects. ORM is object relational mapper and ODM is object document mapper. With these ORM / ODM you also need to choose what database to use such as
  • MySQL
  • PostgreSQL
  • MongoDB
  • Oracle
  • Microsoft SQL Database
  • Firebase ( realtime database )
After choosing a database you also can implements services that already completely work on production such as
  • Firebase ( Realtime Database, Authentication, CDN )
  • One Signal ( Notification )
  • Here WeGo / Google Maps ( Maps )
  • Docker ( Packaging apps )
  • Docker Composer ( Container for storing docker app )
  • Kubernetes [ k8s ] ( Container for storing docker app )
With these frameworks, orm, services can speed up your development speed. These api endpoints can testing & write tests by using Postman.

Backend Components

Most of the backend frameworks has almost same components / structures. They would have controller for processing data, router for map api to url and middleware for pre-access of incoming requests ( means that will run before controller ). If framework come with some data mapper, they would have models / entities for database objects, migration for scripting table of database objects, and lifecycle for handling lifecycle of models like ( beforeAction & afterAction ). Some of the framework or data mapper still have extra features for this but i not going to explain that cause still have some different on all of the framework but these 6 is most common at all backend frameworks. Before move on to these components i will explaining about requests & responses.

Next part will talk about incoming requests & responses.

Preparing some plugins for upcoming server

Since i still having a free server from mine friends who in Taiwan keep supporting me for server hosting. For long time busy, and he hope i would still operate and having a survival server so i coming to build up a survival server that not like before only enhance survival gameplay instead of new gameplay and make player doesn't even know how to play. Here come with some idea before i preparing: Custom Building Structure ( Make player easier for some basic works ) Custom PvP & PvE Mechanic ( Make item flexible with skill system and update-able, also work with entity ) Socialize Gamplay ( Guilds & Friends & Party & Mail System ) Daily Gameplay ( Questing, Events )  Any suggestion would be appreciated ( welcome to inbox me :] ) Some images about mine developments in these 2 days. Mine Structure API Skill API work with Items system & Status system And here is the video about the Custom Building Structure Part. As past exp

A long journey before i going back to other platforms

That's a long journey for going work on mine other projects due to i participate a startup mate together work on a startup projects. In the projects, i learn and workaround back-end framework in many of languages ( due to private work cant show too much code ). Also i does self-taught some front-end frameworks by learn from mine front-end mate's code & re-base using flutter . It was taken about half of a year to build up a proper back-end server due to inexperienced of my skills and technique so take time to learn. I have also played around many frameworks such as   Back-end ExpressJS - Most basic of the back-end frameworks NestJS - A progressive Node.js framework for building efficient and scalable server-side applications on top of TypeScript & JavaScript (ES6, ES7, ES8) heavily inspired by Angular SailsJS - A MVC framework inspired from Ruby on Rails, have a really good structure and newbie friendly HapiJS - Quite same with Express but more exte
