Today's story

A backend engineer

made a Single-page application

by modern frontend technologies

in 2 weeks.

1. About the SPA and architecture
2. How I've made the SPA
3. Technical challenges I've faced

Architecture

1. About the SPA and architecture
2. How I've made the SPA
3. Technical challenges I've faced

Sub topics

Choose technologies

Since Flux is just architecture (like MVC), we have to choose an implementation.

Redux

It has most GitHub stars in flux libraries

"Redux evolves the ideas of Flux, but avoids its complexity by taking cues from Elm."

Flux

Redux

All right, let's start development!

...but, what should we start from?

In my case

1. Grasp the concept of the technologies

Reference 1

2. Write a small application without Redux(Flux)

Reference 2

(and prepare your dev tools)

  • Editor: Atom + react plugins
  • Debug: Chrome dev tool, redux-logger, hot loaders 

3. Rewrite the small application with Redux

Reference 3

Redux official documents & code examples

(http://rackt.org/redux/)

4. It's time to write an

awesome SPA!

1. About the SPA and architecture
2. How I've made the SPA
3. Technical challenges I've faced

Sub topics

I could not understand the architecture of Redux...

COMPLEX !

"Practice makes perfect."

Let's write more codes!

There are many sample codes and good documents on GitHub.

Cross-Domain problem

<< Browser raises an error! >>

It could have been

solved by JSONP

(Wikipedia API does not support CORS)

SPA states cannot be shared between each devices

because those are saved in browser's LocalStorage

Firebase helped me!

(Firebase is one of BaaS)

It offers realtime JSON datastore and OAuth feature

Conclusion

・SPA and serverless architecture is elegant!

(to infrastructure engineers) 

・We have to take a second look at the new frontend development

(e.g. stop modifying DOM by self)

・The backend engineer could make an SPA in 2 weeks, you might acquire those more earlier!

Let's try to write SPA with advanced techs!

Thank you for your attention!
