Wasagram

A web app for sharing photos and interacting with friends.

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 example of an API server
  • service/globaltime contains a wrapper package for time.Time (useful in unit testing)
• vendor/ is managed by Go, and contains a copy of all dependencies
• webui/ is an example of a 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

Other project files include:

• open-npm.sh starts a new (temporary) container using node:lts image for safe web frontend development (you don't want to use npm in your system, do you?)

Go vendoring

This project uses Go Vendoring. You must use go mod vendor after changing some dependency (go get or go mod tidy) and add all files under vendor/ directory in your commit.

For more information about vendoring:

• https://go.dev/ref/mod#vendoring
• https://www.ardanlabs.com/blog/2020/04/modules-06-vendoring.html

Node/NPM vendoring

This repository contains the webui/node_modules directory with all dependencies for Vue.JS. You should commit the content of that directory and both package.json and package-lock.json.

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/

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
