# getwtxt  [![Build Status](https://travis-ci.com/getwtxt/getwtxt.svg?branch=master)](https://travis-ci.com/getwtxt/getwtxt) [![Go Report Card](https://goreportcard.com/badge/github.com/getwtxt/getwtxt)](https://goreportcard.com/report/github.com/getwtxt/getwtxt) [![Code Climate Maintainability](https://api.codeclimate.com/v1/badges/0e48bd9002de0f84b24e/maintainability)](https://codeclimate.com/github/getwtxt/getwtxt/maintainability) 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.   \[ [Installation](#installation) \]   \[ [Upgrading](#upgrading) \]   \[ [Configuration](#configuration) \]   \[ [Using the Registry](#using-the-registry) \]   \[ [Benchmarks](#benchmarks) \]   \[ [Other Documentation](#other-documentation) \]   \[ [Notes](#notes) \] ## Features  [![GitHub release](https://img.shields.io/github/release/getwtxt/getwtxt.svg)](https://github.com/getwtxt/getwtxt/releases/latest) * Easy to set up and maintain * Uses an in-memory cache to serve requests * Pushes to a database at a configurable interval for persistent storage * `leveldb (default)` * `sqlite3` * More database support is in development * Run directly facing the internet or behind `Caddy` / `nginx` * Optional `TLS` support * Optional hostname matching (serve requests for eg. `twtxt.example.com` without a reverse proxy) ## Public Instances * [twtxt.tilde.institute](https://twtxt.tilde.institute) * [twtxt.envs.net](https://twtxt.envs.net/) Would you like your instance listed? Submit a PR or shoot me an email :) ## Installation I have only personally tested getwtxt on Linux, specifically: * `Debian 9, 10/Testing, Sid` * `Ubuntu Server 18.04LTS, 18.10, 19.04` Build dependencies are minimal, and only include: * `gnu make` * `go >= 1.11` * `git` First, fetch the sources using `git` and jump into the directory. ``` $ git clone git://github.com/getwtxt/getwtxt.git ... $ cd getwtxt ``` Then, check out the latest release tag. This will be the same tag listed on the badge under the [Features](#features) section heading. ``` $ git checkout v0.0.0 ``` Or, if you want to be a `git` ninja, you can use this to just check out whatever the latest tag is: ``` $ git checkout $(git describe --tags --abbrev=0) ``` Optionally, use the `go` tool to test and benchmark the files in `svc`. ``` $ go test -v -bench . -benchmem ./... ... ... PASS ``` Use `make` to initiate the build and install process. ``` $ make ... $ sudo make install ``` ## Upgrading Upgrading is a fairly simple process. First, we need to commit your local changes to the configuration file. ``` $ cp /usr/local/getwtxt/getwtxt.yml . $ git add getwtxt.yml $ git commit -m 'my local config' ``` Now, we need to either run `make update` or `git pull --rebase` ``` $ make update ... ``` Afterwards, follow the normal instructions for building and installing. If no configuration changes have been made since your last upgrade, you will not need to commit them again. While `getwtxt` is pre-`1.0`, any patch-level updates (`v0.4.x`) will not change configuration values. Of course, you can also just back up your configuration file, then copy it back into `/usr/local/getwtxt/` after installing the new version. ## 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 (yet). 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. * [twtxt.tilde.institute](https://twtxt.tilde.institute) ### 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 ``` $ curl 'https://twtxt.example.com/api/plain/tweets' foo_barrington https://foo.bar.ext/twtxt.txt 2019-03-01T09:31:02.000Z Hey!

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 ``` ## Notes twtxt Information: [`twtxt.readthedocs.io`](https://twtxt.readthedocs.io) Interested in twtxt but don't have your own server?
