-## 👀 Hosted Service
-🔥 **New:** Wakapi is available as a hosted service now. Check out **[wakapi.dev](https://wakapi.dev)**. Please use responsibly.
+<p align="center">
+  <img src="static/assets/images/screenshot.png" width="500px">
+</p>

-To use the hosted version set `api_url = https://wakapi.dev/api/heartbeat`. However, we do not guarantee data persistence, so you might potentially lose your data if the service is taken down some day ❕

If you have feature requests or any kind of improvement proposals feel free to open an issue or share them in our [user survey](https://github.com/muety/wakapi/issues/82). 
+
+## ⌨️ How to use?
+There are different options for how to use Wakapi, ranging from our hosted cloud service to self-hosting it. Regardless of which option choose, you will always have to do the [client setup](#-client-setup) in addition. 
+
+### ☁️ Option 1: Use [wakapi.dev](https://wakapi.dev)
+If you want to you out free, hosted cloud service, all you need to do is create an account and the set up your client-side tooling (see below).
+
+However, we do not guarantee data persistence, so you might potentially lose your data if the service is taken down some day ❕
+
+### 🐳 Option 2: Use Docker
+```bash
+# Create a persistent volume
+$ docker volume create wakapi-data
+
+# Run the container
+$ docker run -d \
+  -p 3000:3000 \
+  -e "WAKAPI_PASSWORD_SALT=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w ${1:-32} | head -n 1)" \
+  -v wakapi-data:/data \
+  --name wakapi n1try/wakapi
+```
+
+**Note:** By default, SQLite is used as a database. To run Wakapi in Docker with MySQL or Postgres, see [Dockerfile](https://github.com/muety/wakapi/blob/master/Dockerfile) and [config.default.yml](https://github.com/muety/wakapi/blob/master/config.default.yml) for further options.
+
+### 📦 Option 3: Run a release
+```bash
+# Download the release and unpack it
+$ wget https://github.com/muety/wakapi/releases/download/1.20.2/wakapi_linux_amd64.zip
+$ unzip wakapi_linux_amd64.zip
+
+# Optionally adapt config to your needs
+$ vi config.yml
+
+# Run it
+$ ./wakapi
+```
+
+### 🧑‍💻 Option 4: Run from source
+#### Prerequisites
 * Go >= 1.13 (with `$GOPATH` properly set)
 * gcc (to compile [go-sqlite3](https://github.com/mattn/go-sqlite3))
    * Fedora / RHEL: `dnf install @development-tools`
    * Ubuntu / Debian: `apt install build-essential`
    * Windows: See [here](https://github.com/mattn/go-sqlite3/issues/214#issuecomment-253216476)
-* _Optional_: A MySQL- or Postgres database

-**On your local machine:**
-* [WakaTime plugin](https://wakatime.com/plugins) for your editor / IDE
+#### Compile & Run
+```bash
+# Adapt config to your needs
+$ cp config.default.yml config.yml
+$ vi config.yml

-## ⌨️ Server Setup
-### Run from source
-1. Clone the project
-1. Copy `config.default.yml` to `config.yml` and adapt it to your needs
-1. Build executable: `GO111MODULE=on go build`
-1. Run server: `./wakapi`
+# Install packaging tool
+$ export GO111MODULE=on
+$ go get github.com/markbates/pkger/cmd/pkger

-**As an alternative** to building from source you can also grab a pre-built [release](https://github.com/muety/wakapi/releases). Steps 2, 3 and 5 apply analogously.
+# Build the executable
+$ go generate
+$ go build -o wakapi

-**Note:** By default, the application is running in dev mode. However, it is recommended to set `ENV=production` for enhanced performance and security. To still be able to log in when using production mode, you either have to run Wakapi behind a reverse proxy, that enables for HTTPS encryption (see [best practices](#best-practices)) or set `security.insecure_cookies` to `true` in `config.yml`. 
-
-### Run with Docker
-```
-docker run -d -p 3000:3000 --name wakapi n1try/wakapi
+# Run it
+$ ./wakapi
 ```

-By default, SQLite is used as a database. To run Wakapi in Docker with MySQL or Postgres, see [Dockerfile](https://github.com/muety/wakapi/blob/master/Dockerfile) and [config.default.yml](https://github.com/muety/wakapi/blob/master/config.default.yml) for further options.

-## 🔧 Configuration
+### 💻 Client Setup
+Wakapi relies on the open-source [WakaTime](https://github.com/wakatime/wakatime) client tools. In order to collect statistics to Wakapi, you need to set them up.
+
+1. **Set up WakaTime** for your specific IDE or editor. Please refer to the respective [plugin guide](https://wakatime.com/plugins)
+2. **Editing your local `~/.wakatime.cfg`** file as follows
+
+```ini
+[settings]
+
+# Your Wakapi server URL or 'https://wakapi.dev/api/heartbeat' when using the cloud server
+api_url = http://localhost:3000/api/heartbeat
+
+# Your Wakapi API key (get it from the web interface after having created an account)
+api_key = 406fe41f-6d69-4183-a4cc-121e0c524c2b
+```
+
+Optionally, you can set up a [client-side proxy](docs/advanced_setup.md) in addition.
+
+## 🔧 Configuration Options
 You can specify configuration options either via a config file (default: `config.yml`, customziable through the `-c` argument) or via environment variables. Here is an overview of all options.

-## 💻 Client Setup
-Wakapi relies on the open-source [WakaTime](https://github.com/wakatime/wakatime) client tools. In order to collect statistics to Wakapi, you need to set them up.
+### Supported databases
+Wakapi uses [GORM](https://gorm.io) as an ORM. As a consequence, a set of different relational databases is supported.
+* [SQLite](https://sqlite.org/) (_default, easy setup_)
+* [MySQL](https://hub.docker.com/_/mysql) (_recommended, because most extensively tested_)
+* [MariaDB](https://hub.docker.com/_/mariadb) (_open-source MySQL alternative_)
+* [Postgres](https://hub.docker.com/_/postgres) (_open-source as well_)
+* [CockroachDB](https://www.cockroachlabs.com/docs/stable/install-cockroachdb-linux.html) (_cloud-native, distributed, Postgres-compatible API_)

-1. **Set up WakaTime** for your specific IDE or editor. Please refer to the respective [plugin guide](https://wakatime.com/plugins)
-2. Make your local WakaTime client talk to Wakapi by **editing your local `~/.wakatime.cfg`** file as follows
-
-```
-api_url = https://your.server:someport/api/heartbeat`
-api_key = the_api_key_printed_to_the_console_after_starting_the_server`
-```
-
-You can view your API Key after logging in to the web interface.
-
-## 🔵 Customization
-
-### Aliases
-There is an option to add aliases for project names, editors, operating systems and languages. For instance, if you want to map two projects – `myapp-frontend` and `myapp-backend` – two a common project name – `myapp-web` – in your statistics, you can add project aliases.
-
-At the moment, this can only be done via raw database queries. For the above example, you would need to add two aliases, like this:
-
-```sql
-INSERT INTO aliases (`type`, `user_id`, `key`, `value`) VALUES (0, 'your_username', 'myapp-web', 'myapp-frontend');
-```
-
-#### Types
-* Project ~  type **0**
-* Language ~  type **1**
-* Editor ~ type **2**
-* OS ~  type **3**
-* Machine ~  type **4**
+### Client-side proxy (`optional`)
+See the [advanced setup instructions](docs/advanced_setup.md).

 ## 🔧 API Endpoints
-The following API endpoints are available. A more detailed Swagger documentation is about to come ([#40](https://github.com/muety/wakapi/issues/40)).

-## ⤴️ Prometheus Export
-If you want to export your Wakapi statistics to Prometheus to view them in a Grafana dashboard or so please refer to an excellent tool called **[wakatime_exporter](https://github.com/MacroPower/wakatime_exporter)**.
+## 🤝 Integrations
+### Prometheus Export
+You can export your Wakapi statistics to Prometheus to view them in a Grafana dashboard or so. Here is how.

-[![](https://github-readme-stats.vercel.app/api/pin/?username=MacroPower&repo=wakatime_exporter&show_owner=true)](https://github.com/MacroPower/wakatime_exporter)
+```bash
+# 1. Start Wakapi with the feature enabled
+$ export WAKAPI_EXPOSE_METRICS=true
+$ ./wakapi

-It is a standalone webserver that connects to your Wakapi instance and exposes the data as Prometheus metrics. Although originally developed to scrape data from WakaTime, it will mostly for with Wakapi as well, as the APIs are partially compatible.
+# 2. Get your API key and hash it
+$ echo "<YOUR_API_KEY>" | base64

-Simply configure the exporter with `WAKA_SCRAPE_URI` to equal `"https://wakapi.your-server.com/api/compat/wakatime/v1"` and set your API key accordingly.
+# 3. Add a Prometheus scrape config to your prometheus.yml (see below)
+```

-## 🏷 Badges
-We recently introduced support for [Shields.io](https://shields.io) badges (see above). Visit your Wakapi server's settings page to see details.
+#### Scrape config example
+```yml
+# prometheus.yml
+# (assuming your Wakapi instance listens at localhost, port 3000)
+
+scrape_configs:
+  - job_name: 'wakapi'
+    scrape_interval: 1m
+    metrics_path: '/api/metrics'
+    bearer_token: '<YOUR_BASE64_HASHED_TOKEN>'
+    static_configs:
+      - targets: ['localhost:3000']
+```
+
+#### Grafana 
+There is also a [nice Grafana dashboard](https://grafana.com/grafana/dashboards/12790), provided by the author of [wakatime_exporter](https://github.com/MacroPower/wakatime_exporter).
+
+![](https://grafana.com/api/dashboards/12790/images/8741/image)
+
+### WakaTime Integration
+Wakapi plays well together with [WakaTime](https://wakatime.com). For one thing, you can **forward heartbeats** from Wakapi to WakaTime to effectively use both services simultaneously. In addition, there is the option to **import historic data** from WakaTime for consistency between both services. Both features can be enabled in the _Integrations_ section of your Wakapi instance's settings page.     
+
+### GitHub Readme Stats Integrations
+Wakapi also integrates with [GitHub Readme Stats](https://github.com/anuraghazra/github-readme-stats#wakatime-week-stats) to generate fancy cards for you. Here is an example.
+
+![](https://github-readme-stats.vercel.app/api/wakatime?username=n1try&api_domain=wakapi.dev&bg_color=2D3748&title_color=2F855A&icon_color=2F855A&text_color=ffffff&custom_title=Wakapi%20Week%20Stats&layout=compact)

 ## 👍 Best Practices
 It is recommended to use wakapi behind a **reverse proxy**, like [Caddy](https://caddyserver.com) or _nginx_ to enable **TLS encryption** (HTTPS).
 However, if you want to expose your wakapi instance to the public anyway, you need to set `server.listen_ipv4` to `0.0.0.0` in `config.yml`

-## ⚠️ Important Note
-**This is not an alternative to using WakaTime.** It is just a custom, non-commercial, self-hosted application to collect coding statistics using the already existing editor plugins provided by the WakaTime community. It was created for personal use only and with the purpose of keeping the sovereignity of your own data. However, if you like the official product, **please support the authors and buy an official WakaTime subscription!**
+## 🤓 Developer Notes
+### Running tests
+```bash
+CGO_FLAGS="-g -O2 -Wno-return-local-addr" go test -json -coverprofile=coverage/coverage.out ./... -run ./...
+```
+
+## 🙏 Support
+If you like this project, please consider supporting it 🙂. You can donate either through [buying me a coffee](https://buymeacoff.ee/n1try) or becoming a GitHub sponsor. Every little donation is highly appreciated and boosts the developers' motivation to keep improving Wakapi!
+
+## ❔ FAQs
+Since Wakapi heavily relies on the concepts provided by WakaTime, [their FAQs](https://wakatime.com/faq) apply to Wakapi for large parts as well. You might find answers there.
+
+<details>
+<summary><b>What data is sent to Wakapi?</b></summary>
+
+<ul>
+  <li>File names</li>
+  <li>Project names</li>
+  <li>Editor names</li>
+  <li>You computer's host name</li>
+  <li>Timestamps for every action you take in your editor</li>
+  <li>...</li>
+</ul>
+
+See the related [WakaTime FAQ section](https://wakatime.com/faq#data-collected) for details.
+
+If you host Wakapi yourself, you have control over all your data. However, if you use our webservice and are concerned about privacy, you can also [exclude or obfuscate](https://wakatime.com/faq#exclude-paths) certain file- or project names.  
+</details>
+
+<details>
+<summary><b>What happens if I'm offline?</b></summary>
+
+All data is cached locally on your machine and sent in batches once you're online again.
+</details>
+
+<details>
+<summary><b>How did Wakapi come about?</b></summary>
+
+Wakapi was started when I was a student, who wanted to track detailed statistics about my coding time. Although I'm a big fan of WakaTime I didn't want to pay <a href="https://wakatime.com/pricing)">9 $ a month</a> back then. Luckily, most parts of WakaTime are open source!  
+</details>
+
+<details>
+<summary><b>How does Wakapi compare to WakaTime?</b></summary>
+
+Wakapi is a small subset of WakaTime and has a lot less features. Cool WakaTime features, that are missing Wakapi, include:
+
+<ul>
+  <li>Leaderboards</li>
+  <li><a href="https://wakatime.com/share/embed">Embeddable Charts</a></li>
+  <li>Personal Goals</li>
+  <li>Team- / Organization Support</li>
+  <li>Integrations (with GitLab, etc.)</li>
+  <li>Richer API</li>
+</ul>
+
+WakaTime is worth the price. However, if you only want basic statistics and keep sovereignty over your data, you might want to go with Wakapi.
+</details>
+
+<details>
+<summary><b>How are durations calculated?</b></summary>
+
+Inferring a measure for your coding time from heartbeats works a bit different than in WakaTime. While WakaTime has <a href="https://wakatime.com/faq#timeout">timeout intervals</a>, Wakapi essentially just pads every heartbeat, that occurs after a longer pause, with 2 extra minutes.
+
+Here is an example (circles are heartbeats):
+
+```
+|---o---o--------------o---o---|
+|   |10s|      3m      |10s|   |
+
+```
+
+It is unclear how to handle the three minutes in between. Did the developer do a 3-minute break or were just no heartbeats being sent, e.g. because the developer was starring at the screen find a solution, but not actually typing code.
+
+<ul>
+  <li><b>WakaTime</b> (with 5 min timeout): 3 min 20 sec
+  <li><b>WakaTime</b> (with 2 min timeout): 20 sec
+  <li><b>Wakapi:</b> 10 sec + 2 min + 10 sec = 2 min 20 sec</li>
+</ul>
+
+Wakapi adds a "padding" of two minutes before the third heartbeat. This is why total times will slightly vary between Wakapi and WakaTime.
+</details>

+# Advanced Setup
+This page contains instructions for additional setup options, none of which are mandatory.
+
+## Optional: Client-side proxy
+Most Wakatime plugins work in a way that, for every heartbeat to send, the plugin calls your local [wakatime-cli](https://github.com/wakatime/wakatime) (a small Python program that is automatically installed when installing a Wakatime plugin) with a few command-line arguments, which is then run as a new process. Inside that process, a heartbeat request is forged and sent to the backend API – Wakapi in this case.
+
+While this is convenient for plugin developers, as they do not have to deal with sending HTTP requests, etc., it comes with a minor drawback. Because the CLI process shuts down after each request, its TCP connection is closed as well. Accordingly, **TCP connections cannot be re-used** and every single heartbeat request is inevitably preceded by the `SYN` + `SYN ACK` + `ACK` sequence for establishing a new TCP connection as well as a handshake for establishing a new TLS session.
+
+While this certainly does not hurt, it is still a bit of overhead. You can avoid that by setting up a local reverse proxy on your machine, that keeps running as a daemon and can therefore keep a continuous connection.
+
+### Option 1: [tinyproxy](https://tinyproxy.github.io) forward proxy (`Linux`, `Mac` only)
+In this example we use _tinyproxy_ as a small, easy-to-install proxy server, written in C, that runs on your local machine.
+1. Install [tinyproxy](https://tinyproxy.github.io)
+   * Fedora / RHEL: `dnf install tinyproxy`
+   * Debian / Ubuntu: `apt install tinyproxy`
+   * MacOS: Install from [MacPorts](https://ports.macports.org/port/tinyproxy/summary)
+1. Enable and start it
+   * Linux: `sudo systemctl start tinyproxy && sudo systemctl enable tinyproxy`
+   * Mac: Not sure, sorry ¯\_(ツ)_/¯
+1. Update `~/.wakatime.cfg`
+   * Set `proxy = http://localhost:8888`
+1. Done
+   * All Wakapi requests are passed through tinyproxy now, which keeps a TCP connection with the server open for some time
+
+### Option 2: [Caddy](https://caddyserver.com) reverse proxy (`Win`, `Linux`, `Mac`)
+In this example, we misuse Caddy, which is a web server and reverse proxy, to fulfil the above scenario. 
+
+1. [Install Caddy](https://caddyserver.com/) 
+    * When installing manually, don't forget to set up a systemd service to start Caddy on system startup
+1. Create a Caddyfile
+    ```
+    # /etc/caddy/Caddyfile
+   
+    http://localhost:8070 {
+        reverse_proxy * {
+            to https://wakapi.dev  # <-- substitute your own Wakapi host here
+            header_up Host {http.reverse_proxy.upstream.host}
+            header_down -Server
+        }
+    }
+    ```
+1. Restart Caddy
+1. Verify that you can access [`http://localhost:8070/api/health`](http://localhost:8070/api/health)
+1. Update `~/.wakatime.cfg`
+    * Set `api_url = http://localhost:8070/api/heartbeat`
+1. Done
+   * All Wakapi requests are passed through Caddy now, which keeps a TCP connection with the server open for some time
