# nonshy website
This is the source code to the main [nonshy.com](https://www.nonshy.com/)
website. It is written in Go and released under the GNU General Public
License.
This website is open source and if you'd like to help work on it (fix bugs
or contribute new features), you may sign up an account on the
[code.nonshy.com](https://code.nonshy.com/) server. See the
[CONTRIBUTING.md](CONTRIBUTING.md) file for details.
## Dependencies
You may need to run the following services along with this app:
* A **Redis cache** server: [redis.io](https://redis.io)
* (Optional) a **PostgreSQL database:** [postgresql.org](https://www.postgresql.org/)
The website can also run out of a local SQLite database which is convenient
for local development. The production server runs on PostgreSQL and the
web app is primarily designed for that.
## Building the App
This app is written in Go: [go.dev](https://go.dev). You can probably
get it from your package manager, e.g.
* macOS: `brew install golang` with homebrew: [brew.sh](https://brew.sh)
* Linux: it's in your package manager, e.g. `apt install golang`
Use the Makefile (with GNU `make` or similar):
* `make setup`: install Go dependencies
* `make build`: builds the program to ./nonshy
* `make run`: run the app from Go sources in debug mode
Or read the Makefile to see what the underlying `go` commands are,
e.g. `go run cmd/nonshy/main.go web`
## Configuring
On first run it will generate a `settings.json` file in the current
working directory (which is intended to be the root of the git clone,
with the ./web folder). Edit it to configure mail settings or choose
a database.
For simple local development, just set `"UseSQLite": true` and the
app will run with a SQLite database.
## Usage
The `nonshy` binary has sub-commands to either run the web server
or perform maintenance tasks such as creating admin user accounts.
Run `nonshy --help` for its documentation.
Run `nonshy web` to start the web server.
```bash
nonshy web --host 0.0.0.0 --port 8080 --debug
```
## Create Admin User Accounts
Use the `nonshy user add` command like so:
```bash
$ nonshy user add --admin \
--email name@domain.com \
--password secret \
--username admin
```
Shorthand options `-e`, `-p` and `-u` can work in place of the longer
options `--email`, `--password` and `--username` respectively.
After the first admin user is created, you may promote other users thru
the web app by using the admin controls on their profile page.
## A Brief Tour of the Code
* `cmd/nonshy/main.go`: the entry point for the Go program.
* `pkg/webserver.go`: the entry point for the web server.
* `pkg/config`: mostly hard-coded configuration values - all of the page
sizes and business logic controls are in here, set at compile time. For
ease of local development you may want to toggle SkipEmailValidation in
here - the signup form will then directly allow full signup with a user
and password.
* `pkg/controller`: the various web endpoint controllers are here,
categorized into subpackages (account, forum, inbox, photo, etc.)
* `pkg/log`: the logging to terminal functions.
* `pkg/mail`: functions for delivering HTML email messages.
* `pkg/markdown`: functions to render GitHub Flavored Markdown.
* `pkg/middleware`: HTTP middleware functions, for things such as:
* Session cookies
* Authentication (LoginRequired, AdminRequired)
* CSRF protection
* Logging HTTP requests
* Panic recovery for unhandled server errors
* `pkg/models`: the SQL database models and query functions are here.
* `pkg/models/deletion`: the code to fully scrub wipe data for
user deletion (GDPR/CCPA compliance).
* `pkg/photo`: photo management functions: handle uploads, scale and
crop, generate URLs and deletion.
* `pkg/ratelimit`: rate limiter for login attempts etc.
* `pkg/redis`: Redis cache functions - get/set JSON values for things like
session cookie storage and temporary rate limits.
* `pkg/router`: the HTTP route URLs for the controllers are here.
* `pkg/session`: functions to read/write the user's session cookie
(log in/out, get current user, flash messages)
* `pkg/templates`: functions to handle HTTP responses - render HTML
templates, issue redirects, error pages, ...
* `pkg/utility`: miscellaneous useful functions for the app.
