What did we do
and why?

Technological Stack

Technological Stack

Wix-Angular

  • Yeoman generator

  • Adopted my multiple teams at Wix
  • Internal open source
  • Public (partial) open source
    at                .com/wix

Large Scale

Large Scale

VERY

Minimum Viable Product

Minimum is a lot

...because of the old product

Minimum Viable Product We’re Proud Of

Use BI

to define our average store

Use BI

to compare new and old

(after launch)

Gradual Exposure

  • Only new users
  • Only in the US
  • 5%
  • 20%
  • 50%
  • 100%

Large Team

From 8 to ~35 People

  • 12 Front end devs
  • 7 Back end devs (2 in Ukraine)
  • 1 Automation
  • 2 QAs (Ukraine)
  • 4 Products

Our Repositories

100% Code

Covered by Tests

Goal:

Unit Tests

System Tests

E2E Tests

First time server and client projects integrate

Git:
Rebase, not Merge

With merge there is no revert

Technology
and
Workflow

When to Deploy
New Code?

Always!

Develop on Production

  • Best staging is production

  • Postmortem when production breaks

How does a feature pushed to production?

  1. Create a Feature Toggle, set it to closed
  2. Override Feature Toggle's to true for your User ID 
  3. Start development
  4. (Almost) Daily push code to production
  5. Finish the feature
  6. Gradually expose the feature to users by  A/B Test
  7. Monitor errors, logs, BI, Biz KPIs (# of premiums)

Monitoring Systems

Tests, BI and BAM (Business Activity Monitoring) alerts

TypeScript

  • Type safety
  • ECMAScript 6 friendly
  • Great IDE support

Objects, not Pages

CSS Framework

CSS today is...

  • Powerful
  • Has pre-processors
  • Cross-browser
  • More complex

CSS is First Class Citizen

Plan Ahead

Vector Graphics 

Forget about Gif, Jpeg, Png...

Client Side App

Look ma, no server!

Server
Provides
Persistence

One Point for
Data Entry

One Point for Data Entry

Backend API

View Loades

View Data Service

Data Facade Service

Ajax Http Service

Offline Storage

Why?

  • Better user experience
  • Offline usage
  • Can be packaged with PhoneGap
  • "Standalone" application

Server Side Rendering
vs.
Client Side Rendering

We Do Both

Kinda...

User Requests a Page

Server Render w/ JSON Inside

Client App Bootstraps

Client Side View Render

User Clicks "Load More" Button

Ajax Request-Response w/ JSON

Client Side View Render

What Now?

  • Easy to add features
  • Fast time to production
  • Managed code
  • Modern stack
  • Easy to "market" positions
    to new developers
  • MVP, that we're proud of
  • Impressive roadmap ahead

Thank You :)
