A simple video streaming application made with Dart, JS, HTML, CSS &

Recently I wrote an article, explaining how to deploy it using systemd in LAN, which can be found here.

what does it do ?

A streaming service, intended to run in small network(s) ( may be in your home network ), which lets you stream movies to any device present in that network & having a standard browser installed ( yeah HTML5 support required )
Backend, fully written in Dart, leveraging power of dart:io & dart:isolate
Frontend, powered by HTML, CSS & last but not least Javascript ( yeah not using any UI framework )
Audio-Video playing is done using HTML5 <video> element, which can play mp4 & webm video(s) generally

how can I use it ?

If you’re on Linux, then I’ve already compiled streamZ into an executable binary ( using dart2native compiler ), which can be simply run on any Linux Machine, cause that executable binary is one self-sufficient one ( but not yet platform-agnostic, which will change is near future ).
Then download this compressed file, and unzip it into a suitable location on your machine.
You’ll get a directory tree like below

$ wget https://github.com/itzmeanjan/streamZ/releases/download/v1.0.1/streamZ.zip # consider downloading zip, using wget from terminal
$ cd
$ unzip streamZ.zip # unzipping it
$ cd streamZ # getting into actual directory
$ tree -h
.

│   └── [7.8M]  streamZ

6 directories, 5 files

Now get into ./final directory & run executable binary, which will start a media streaming server on http://0.0.0.0:8000

$ cd final
$ ./streamZ # running movie steaming server
[+]streamZ_v1.0.0 listening ( streamZ0 ) ...

[+]streamZ_v1.0.0 listening ( streamZ1 ) ...

To check, open browser from same machine & type http://localhost:8000 into address bar, you’ll get a list of all movies present under ~/Videos/ directory, which is default video storing directory on Linux running machines.
You can also access this streaming service by opening _http://x.x.x.x:8000/_,on any device’s browser, present in LAN
Where x.x.x.x is nothing but Local IP Address of machine, running streamZ

If you want to dig deeper, simply fork this repo & clone it in you machine
Make sure you’ve installed Dart SDK & you’re on *nix platform
Because I gonna use systemd.service to keep this streaming service alive in background, always, even after system restarts it’ll auto start itself
You need to make sure, you’ve ~/Videos/ directory present on your system, cause we’ll read from that directory ( every 30 minutes ), to ensure all mp4 & webm videos, present in aforementioned directory, are listed in movie playlist
If you’re having a lot of traffic, consider using multiple Isolates to handle traffic efficiently. Just update int count = 2; on line 100 of ./bin/main.dart to whatever value you intend to use, that many Isolate(s) will be created on boot, they’ll distributedly handle whole traffic coming in.
I’ve also written one systemd unit file, which can be used for deploying streamZ, so that it’ll keep running always ( autostart after failure & system boot )
Consider using so, by modifying this systemd unit file
