Welcome to Holmusk Mobile Engineering challenge

You are just assigned to a new (exciting) app! It's a simple chat app that let user communicate their friends via media message.

Scenario

A (wild) PROJECT MANAGER appear with a set requirements and wireframes !

Requirements:

• User can Login or Create account to use app features.
• User can view and edit their profile.
• User can refresh their profile.
• User can see and refresh list of their friends.
• User can see and refresh message from their friend inside a chat room.
• User can send text and image (camera and photo library).
• User can refresh message list.
• User can access menu from top left button.
• User can toggle app to dark / light mode.
• User can logout and clear all data.

Wirefame

Then you turn to your watchful protector, the silent knight, the BACKEND ENGINEER to get his/her (not so) wise counsel. Alas, his/her hands are also tied with other things right now, but they can promise you these:

• Host: com.simple.chat, scheme: https, port: 433
• Document-type: json
• 200 -> response success and return corresponding data
• 400 -> bad request parameters (shame on you).
• 401 -> sessions expired (user must re login to use the app)
• 404 -> endpoints not found (are you lost?)
• 500 -> Internal server errors (it's just a glitch)

Ignore how user get friends, just assume it's magically populated already.

Endpoints in BLUE means non secure endpoint.

Endpoints in GREEN means secure endpoint - token must be provided in request headers.

Objectives

• You are expected to design a skeleton app in a well structured, robust, modular and testable way.

• This is a mock app, you can cut corner on UI layer.

Ignore the form in login and create page, a button to trigger the action will do. No need to build custom view or widget, just print it to a Text is okay. etc.

• You are expected to test / mock all the api communication to server, so app can seamlessly integrated with live server when it's ready.

• Fell free to use whatever (mobile) platform or libraries you are comfortable with.

Bonus point:

• Mock a Deep link from push-notification delegate/callback feature. (payload: friendId, deep link to chatroom page)

• Logging mechanism at development or production level.

• Dynamic app theme.

• Dynamic app environment (local, staging, production)

• Live connection in chat room.
