PiWorker

PiWorker is a free and open source tool that let you automate tasks easily on your Raspberry Pi (can be used on other devices too) without letting aside your privacy. In these times where your data is used as a payment on some "free" software/services, I think is good to remark that PiWorker does not use any external server for nothing (unless you explicity add an action to doing it), so everything is executed inside your device, under your control.

I'm working hard to make PiWorker stable and robust, but for now, it's not even an alpha, so there should be bugs everywhere (If you see one, can you let me know it please? that will be really helpful!) so don't use it on a device that contain something that you don't want to loose.

Installation:

~~curl -sSL https://github.com/Pegasus8/PiWorker/raw/master/install.sh | sudo bash~~

Installation from source:

Make sure you have golang installed and configured. If not, check this.
Make sure you have nodejs and npm installed. If you don't, install them from here or here (if you use linux maybe the last option will be more easy).
Check if you have git installed. If not (again), get it from here.
Install pkger in your GOPATH running go get github.com/markbates/pkger/cmd/pkger.
Download the source code: git clone https://github.com/Pegasus8/PiWorker.
Once downloaded, go inside the directory cd PiWorker/.
Go to the dir of the frontend cd webui/frontend/, install the dependencies npm install, and compile it npm run build.
Go back to the root PiWorker directory cd ../...
Execute pkger to include the frontend inside the binary.
Compile the entire project (output_dir is the path where the executable will be saved): go build -o <output_dir>. In my case, I prefer save the executable on the directory $HOME/PiWorker/, so I will run the command go build -o $HOME/PiWorker/. Note: the dir used must exist before the compiling.
Go to the directory where you saved the executable: cd <output_dir>. In my case is $HOME/PiWorker/, so I execute: cd $HOME/PiWorker/.
Install the service of P.W. running the following command: sudo ./piworker --service install. Why sudo? Because you need root privileges to add a new service to the system. The service must be installed? No, isn't something essential. If you prefer don't install it, remember that P.W. won't be executed when you reboot the system.
IMPORTANT - Make a new user before start the service: ./piworker --new-user --username <your_username> --password <your_password> --admin. Replace <your_username> with the username you will use and <your_password> with the password. Also, the --admin flag can be avoided if you don't want to give admin privileges to the user. Note: you can add more users if you want.
Optional (but recommended) - Generate a self-signed certificate for a secure connection (https) with the WebUI (Warning: don't use the WebUI/REST APIs from outside the LAN. As a software in early development, can contain vulnerabilities that can be exploited by more experienced people with malicious intentions):

openssl req \
        -subj '/O=PiWorker' \

        -newkey \
