# Go-SSB Room
This repository contains code for a [Secure Scuttlebutt](https://ssb.nz) [Room (v1+v2) server](https://github.com/ssb-ngi-pointer/rooms2), written in Go.
It includes:
* secret-handshake+boxstream network transport, sometimes referred to as SHS, using [secretstream](https://github.com/cryptoscope/secretstream)
* muxrpc handlers for tunneling connections
* a fully embedded HTTP server & HTML frontend, for administering the room
## Features
* [x] Rooms v1 (`tunnel.connect`, `tunnel.endpoints`, etc.)
* [x] Simple allow-listing, administerd via the web dashboard
* [ ] Sign-in with SSB
* [ ] Alias managment
## Development
To get started, you need a recent version of [Go](https://golang.org). v1.16 and onward should be sufficient.
To build the server and see a list of its options:
```bash
cd cmd/server
go build
./server -h
Usage of ./server:
-dbg string
listen addr for metrics and pprof HTTP server (default "localhost:6078")
-lishttp string
address to listen on for HTTP requests (default ":3000")
-lismux string
address to listen on for secret-handshake+muxrpc (default ":8008")
-nounixsock
disable the UNIX socket RPC interface
-logs string
where to write debug output to (default is just stderr)
-repo string
where to put the log and indexes (default "/home/cryptix/.ssb-go-room")
-shscap string
secret-handshake app-key (or capability) (default "1KHLiKZvAvjbY1ziZEHMXawbCEIM6qwjCDm3VYRan/s=")
-version
print version number and build date
```
If you want to view the development server in your browser:
```sh
# change to the root of the project (e.g. cd go-ssb-room) and generate the frontend's styling; requires npm
go generate -tags dev ./...
# now let's build & run the development server
cd cmd/server && go build -tags dev && ./server
# and visit http://localhost:3000
```
This can be useful if you are working on:
* the sqlite migrations,
* html templates,
* or website assets
This way, the build won't use the assets embedded in the binary, but instead read them directly from the local filesystem.
Once you are done with your changes and want to update the embedded assets:
```sh
# cd to the root of the folder, and then run go generate
go generate -tags dev ./...
```
## Tooling
### Mocks
[`counterfeiter`](https://github.com/maxbrunsfeld/counterfeiter) enables generating mocks for defined interfaces. To update the mocks, run `go generate` in package roomdb.
### Database schema
This project uses [sql-migrate](https://github.com/rubenv/sql-migrate) to upgrade the sqlite database when necessary.
To upgrade, create a new file in `admindb/sqlite/migrations` with your changes.
**Note**: similar to the web assets, you need to use `go test -tags dev` to test them. Afterwards run, `go generate` to embed the assets in the code and thus the resulting server binary.
### No ORM
We use [sqlboiler](github.com/volatiletech/sqlboiler) to generate type-safe Go code directly from SQL statements and table definitions. This approach suits the programming language much more then classical ORM approaches, which usually rely havily on reflection for (un)packing structs.
To generate them run the following commands. This will populate `admindb/sqlite/models`:
* (TODO: automate this with `go generate`)
```bash
# also included as generate_models.sh
cd admindb/sqlite
go test
sqlboiler sqlite3 --wipe
```
The generated package `admindb/sqlite/models` is then used to implemente the custom logic of the different services in `admindb/sqlite`.
Aside: I would have used `sqlc` since it's a bit more minimal and uses hand written SQL queries instead of generic query builders but it [currently doesn't support sqlite](https://github.com/kyleconroy/sqlc/issues/161).
### Development user creation
`cmd/insert-user` contains code to create a fallback user. Build it and point it to your database with a username:
```bash
cd cmd/insert-user
go build
# optional step: run a script to generate a valid ssb id @<pubkey>.ed25519, useful for trying things out quickly
./generate-fake-id.sh
./insert-user -name <username> -key <@pubkey.ed25519>
```
Then repeat your password twice and you are all set for development.
Run `insert-user` without any flags to see all the options.
## Testing
### Rooms
The folder `tests/nodejs` contains tests against the JavaScript implementation. To run them, install node and npm and run the following:
```bash
cd tests/nodejs
npm ci
go test
```
### Web Dashboard
The folder `web/handlers` contains the HTTP handlers for the dashboard. Each subfolder comes with unit tests for the specific area (like `auth`, `news`, etc.). Simply run `go test` in one of them or run `go test ./web/...` in the root of the repo to test them all.
