Plans for the near future mainly include, besides usual improvements and bug fixes, a UI redesign as well as additional types of charts and statistics (see [#101](https://github.com/muety/wakapi/issues/101), [#76](https://github.com/muety/wakapi/issues/76), [#12](https://github.com/muety/wakapi/issues/12)). 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 try out a free, hosted cloud service, all you need to do is create an account and then set up your client-side tooling (see below).
### 📦 Option 2: Quick-run a Release
```bash
$ curl -L https://wakapi.dev/get | bash
```
### 🐳 Option 3: Use Docker
```bash
# Create a persistent volume
$ docker volume create wakapi-data
$ SALT="$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w ${1:-32} | head -n 1)"
# Run the container
$ docker run -d \
-p 3000:3000 \
-e "WAKAPI_PASSWORD_SALT=$SALT" \
-v wakapi-data:/data \
--name wakapi \
ghcr.io/muety/wakapi:latest
```
**Note:** By default, SQLite is used as a database. To run Wakapi in Docker with MySQL or Postgres, see [Dockerfile](https://github.com/muety/wakapi/blob/master/Dockerfile) and [config.default.yml](https://github.com/muety/wakapi/blob/master/config.default.yml) for further options.
If you want to run Wakapi on **Kubernetes**, there is [wakapi-helm-chart](https://github.com/andreymaznyak/wakapi-helm-chart) for quick and easy deployment.
### 🧑‍💻 Option 4: Compile and run from source
#### Prerequisites
* Go >= 1.16 (with `$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)
#### Compile & Run
```bash
# Build the executable
$ go build -o wakapi
# Adapt config to your needs
$ cp config.default.yml config.yml
$ vi config.yml
# Run it
$ ./wakapi
```
**Note:** Check the comments `config.yml` for best practices regarding security configuration and more.
### 💻 Client Setup
Wakapi relies on the open-source [WakaTime](https://github.com/wakatime/wakatime) client tools. In order to collect statistics for 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' 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](https://github.com/muety/wakapi/wiki/Advanced-Setup:-Client-side-proxy) in addition.

### 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_)
## 🔧 API Endpoints
See our [Swagger API Documentation](https://wakapi.dev/swagger-ui).
### Generating Swagger docs
```bash
$ go get -u github.com/swaggo/swag/cmd/swag
$ swag init -o static/docs
```
## 🤝 Integrations
### Prometheus Export
You can export your Wakapi statistics to Prometheus to view them in a Grafana dashboard or so. Here is how.
```bash
# 1. Start Wakapi with the feature enabled
$ export WAKAPI_EXPOSE_METRICS=true
$ ./wakapi
# 2. Get your API key and hash it
$ echo "<YOUR_API_KEY>" | base64
# 3. Add a Prometheus scrape config to your prometheus.yml (see below)
```
#### 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)

```
</details>
<br>
### Github Readme Metrics Integration
There is a [WakaTime plugin](https://github.com/lowlighter/metrics/tree/master/source/plugins/wakatime) for GitHub [metrics](https://github.com/lowlighter/metrics/) that is also compatible with Wakapi.
Preview:
![](https://raw.githubusercontent.com/lowlighter/lowlighter/master/metrics.plugin.wakatime.svg)
<details>
<summary>Click to view code</summary>
```yml
- uses: lowlighter/metrics@latest
with:
# ... other options
plugin_wakatime: yes
plugin_wakatime_token: ${{ secrets.WAKATIME_TOKEN }} # Required
plugin_wakatime_days: 7 # Display last week stats
plugin_wakatime_sections: time, projects, projects-graphs # Display time and projects sections, along with projects graphs
plugin_wakatime_limit: 4 # Show 4 entries per graph
plugin_wakatime_url: http://wakapi.dev # Wakatime url endpoint
plugin_wakatime_user: .user.login # User
```
</details>
<br>
## 👍 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`
## 🧪 Tests
### Unit Tests
Unit tests are supposed to test business logic on a fine-grained level. They are implemented as part of the application, using Go's [testing](https://pkg.go.dev/testing?utm_source=godoc) package alongside [stretchr/testify](https://pkg.go.dev/github.com/stretchr/testify).
#### How to run
```bash
$ CGO_FLAGS="-g -O2 -Wno-return-local-addr" go test -json -coverprofile=coverage/coverage.out ./... -run ./...
```
### API Tests
API tests are implemented as black box tests, which interact with a fully-fledged, standalone Wakapi through HTTP requests. They are supposed to check Wakapi's web stack and endpoints, including response codes, headers and data on a syntactical level, rather than checking the actual content that is returned.
Our API (or end-to-end, in some way) tests are implemented as a [Postman](https://www.postman.com/) collection and can be run either from inside Postman, or using [newman](https://www.npmjs.com/package/newman) as a command-line runner.
To get a predictable environment, tests are run against a fresh and clean Wakapi instance with a SQLite database that is populated with nothing but some seed data (see [data.sql](testing/data.sql)). It is usually recommended for software tests to be [safe](https://www.restapitutorial.com/lessons/idempotency.html), stateless and without side effects. In contrary to that paradigm, our API tests strictly require a fixed execution order (which Postman assures) and their assertions may rely on specific previous tests having succeeded.
#### Prerequisites (Linux only)
```bash
# 1. sqlite (cli)
$ sudo apt install sqlite # Fedora: sudo dnf install sqlite
# 2. newman
$ npm install -g newman
```
#### How to run (Linux only)
```bash
$ ./testing/run_api_tests.sh
```
## 🤓 Developer Notes
### Building web assets
To keep things minimal, all JS and CSS assets are included as static files and checked in to Git. [TailwindCSS](https://tailwindcss.com/docs/installation#building-for-production) and [Iconify](https://iconify.design/docs/icon-bundles/) require an additional build step. To only require this at the time of development, the compiled assets are checked in to Git as well.
```bash
$ yarn
$ yarn build # or: yarn watch
```
New icons can be added by editing the `icons` array in [scripts/bundle_icons.js](scripts/bundle_icons.js).
#### Precompression
As explained in [#284](https://github.com/muety/wakapi/issues/284), precompressed (using Brotli) versions of some of the assets are delivered to save additional bandwidth. This was inspired by Caddy's [`precompressed`](https://caddyserver.com/docs/caddyfile/directives/file_server) directive. [`gzipped.FileServer`](https://github.com/muety/wakapi/blob/07a367ce0a97c7738ba8e255e9c72df273fd43a3/main.go#L249) checks for every static file's `.br` or `.gz` equivalents and, if present, delivers those instead of the actual file, alongside `Content-Encoding: br`. Currently, compressed assets are simply checked in to Git. Later we might want to have this be part of a new build step.
To pre-compress files, run this:
```bash
# Install brotli first
$ sudo apt install brotli # or: sudo dnf install brotli
# Watch, build and compress
$ yarn watch:compress
# Alternatively: build and compress only
$ yarn build:all:compress
# Alternatively: compress only
$ yarn compress
```
## ❔ 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 differently 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 trying to 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.
