WASAPhoto

Web And Software Architecture exam project

Description

Keep in touch with your friends by sharing photos of special moments, thanks to WASAPhoto! You can upload your photos directly from your PC, and they will be visible to everyone following you.

Design Specification

Each user will be presented with a stream of photos (images) in reverse chronological order, with information about when each photo was uploaded (date and time) and how many likes and comments it has. The stream is composed by photos from “following” (other users that the user follows).

Users can place (and later remove) a “like” to photos from other users. Also, users can add comments to any image (even those uploaded by themself). Only authors can remove their comments.

Users can ban other users. If user Alice bans user Eve, Eve won’t be able to see any information about Alice. Alice can decide to remove the ban at any moment. Users will have their profiles. The personal profile page for the user shows: the user’s photos (in reverse chronological order), how many photos have been uploaded, and the user’s followers and following. Users can change their usernames, upload photos, remove photos, and follow/unfollow other users. Removal of an image will also remove likes and comments.

A user can search other user profiles via username.

A user can log in just by specifying the username.

Project structure

• cmd/ contains all executables; Go programs here should only do "executable-stuff", like reading options from the CLI/env, etc.
  • cmd/healthcheck is an example of a daemon for checking the health of servers daemons; useful when the hypervisor is not providing HTTP readiness/liveness probes (e.g., Docker engine)
  • cmd/webapi contains an example of a web API server daemon
• demo/ contains a demo config file
• doc/ contains the documentation (usually, for APIs, this means an OpenAPI file)
• service/ has all packages for implementing project-specific functionalities
  • service/api contains an the API server
  • service/database contains database related operations
  • service/globaltime contains a wrapper package for time.Time (useful in unit testing)
  • service/utils contains reusable utility functions for various tasks in the project
• vendor/ is managed by Go, and contains a copy of all dependencies
• webui/ is the web frontend in Vue.js; it includes:
  • Bootstrap JavaScript framework
  • a customized version of "Bootstrap dashboard" template
  • feather icons as SVG
  • Go code for release embedding

OpenAPI

How to view the OpenAPI documentation

Visit the Swagger editor website and paste the API documentation inside doc/api.yaml.

Backend

How to build

If you're not using the WebUI, or if you don't want to embed the WebUI into the final executable, then:

go build ./cmd/webapi/

If you're using the WebUI and you want to embed it into the final executable:

./open-npm.sh
# (here you're inside the NPM container)
npm run build-embed
exit
# (outside the NPM container)
go build -tags webui ./cmd/webapi/

Frontend

How to run (in development mode)

You can launch the backend only using:

go run ./cmd/webapi/

If you want to launch the WebUI, open a new tab and launch:

./open-npm.sh
# (here you're inside the NPM container)
npm run dev

Deployment

How to build the images

Backend

$ docker build -f Dockerfile.backend -t wasaphoto-backend:latest .
