twtxt registry written in Go!
[twtxt](https://github.com/buckket/twtxt) is a decentralized microblogging platform
for hackers based on text files. The user is "followed" and "mentioned" by referencing
the URL to their `twtxt.txt` file and a nickname.
Registries are designed to aggregate several users' statuses into a single location,
facilitating the discovery of new users to follow and allowing the search of statuses
for tags and key words.
## Features
* Easy to set up
* Uses an in-memory cache to serve requests
* Pushes to a database at a configurable interval for persistent storage
* `leveldb (default)`
* `sqlite3`
* Easily run behind `nginx`, `Caddy` or another HTTP server.
## Public Instances
* [twtxt.tilde.institute](https://twtxt.tilde.institute)
* [twtxt.envs.net](https://twtxt.envs.net/)
Would you like your instance listed? Send a message to the [mailing list](https://lists.sr.ht/~gbmor/getwtxt)!
## Installation
I have tested getwtxt on the following:
* `Debian 9, 10`
* `Ubuntu Server 18.04LTS, 18.10, 19.04`
* `OpenBSD 6.6`
Build dependencies are minimal, and only include:
* `make`
* `go >= 1.11`
* `git`
First, fetch the sources using `git` and jump into the directory.
```
$ git clone https://git.sr.ht/~gbmor/getwtxt
...
$ cd getwtxt
```
Then, check out the latest release tag.
```
$ git checkout $(git describe --tags --abbrev=0)
```
Use `make` to initiate the build and install process.
```
$ make
...
$ sudo make install
```
## Upgrading
Upgrading is nearly a identical process. Pull the changes, check out the
latest tag, and rebuild.
systemd might yell at you about running `systemctl daemon-reload` when you
go to restart getwtxt.
While getwtxt is pre-`1.0`, any patch-level updates (`v0.4.x`) will not
change configuration values. If a minor version increase has happened, for
example `v0.4.x -> v0.5.x`, then check if you need to update the config
file before restarting getwtxt.
## Configuration
\[ [Proxying](#proxying) \] \[ [Starting getwtxt](#starting-getwtxt) \]
To configure getwtxt, you'll first need to open `/usr/local/getwtxt/getwtxt.yml`
in your favorite editor and modify any values necessary. There are comments in the
file explaining each option.
If you desire, you may additionally modify the template in
`/usr/local/getwtxt/assets/tmpl/index.html` to customize the page users will see
when they pull up your registry instance in a web browser. The values in the
configuration file under `Instance:` are used to replace text `{{.Like This}}` in
the template.
### Proxying
Though getwtxt will run perfectly fine facing the internet directly, it does not
understand virtual hosts, nor does it use TLS. You'll probably want to proxy it
behind
`Caddy` or `nginx` for this reason.
`Caddy` is ludicrously easy to set up, and automatically handles `TLS`
certificates. Here's the config:
```caddyfile
twtxt.example.com
proxy / example.com:9001
```
If you're using `nginx`, here's a skeleton config to get you started. Don't
forget to change the 5 instances of `twtxt.example.com` to the (sub)domain
you'll be using to access the registry, generate SSL/TLS certificates using
LetsEncrypt, and change the port in `proxy_pass` to whichever port you
specified when modifying the configuration file. Currently, it's set to the
default port `9001`
```nginx
server {
server_name twtxt.example.com;
listen [::]:443 ssl http2;
listen 0.0.0.0:443 ssl http2;
ssl_certificate /etc/letsencrypt/live/twtxt.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/twtxt.example.com/privkey.pem;
include /etc/letsencrypt/options-ssl-nginx.conf;
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
location / {
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_pass http://127.0.0.1:9001;
}
}
server {
if ($host = twtxt.example.com) {
return 301 https://$host$request_uri;
}
listen 80;
server_name twtxt.example.com;
return 404;
}
```
### Starting getwtxt
Once you have everything configured to your needs, use `systemctl` to enable it
to run on system boot, then start the service.
```
$ sudo systemctl enable getwtxt
...
$ sudo systemctl start getwtxt
```
## Using the Registry
The following examples will all apply to using `curl` from a `Linux`, `BSD`, or
`macOS` terminal. All timestamps are in `RFC3339` format, per the twtxt registry
specification. Additionally, all queries support the `?page=N` parameter, where
`N` is a positive integer, that will retrieve page `N` of results in groups of
twenty.
The example API calls can also be found on the landing page of any getwtxt
instance, assuming the admin has not customized the landing page.
### Adding a User
Both nickname and URL are required
```
$ curl -X POST 'https://twtxt.example.com/api/plain/users?url=https://mysite.ext/twtxt.txt&nickname=FooJr'
200 OK
```
### Get All Tweets

## Other Documentation
In addition to what is provided here, additional information, particularly
regarding the configuration file, may be found by running getwtxt with the `-m`
or `--manual` flags. You will likely want to pipe the output to `less` as it is
quite long.
```
$ ./getwtxt -m | less
$ ./getwtxt --manual | less
```
If you need to remove getwtxt from your system, navigate to the source directory
you acquired using `git` during the installation process and run the appropriate
`make` hook:
```
$ sudo make uninstall
```
