# Installation and Setup
Installation of Ultraviolet is simple. You can find a Tl;DR of the installation and setup process just below. If you are unfamiliar with the "standard" installation process, look a bit farther down for a more comprehensive installation and setup guide.
## Basic Guide
```sh
$ git clone https://github.com/titaniumnetwork-dev/Ultraviolet-Node --recursive
$ cd Ultraviolet-Node
$ npm install
$ npm start
```
## Replit Setup Guide
To setup on Replit, first click on the "Run on Replit" button. After loading into your repl, run the following commands:
```sh
$ npm install
$ chmod +x main.sh
$ ./main.sh
```
You will only have to run the second command once. It just allows `main.sh` to be executed. By running `main.sh`, you will update any submodules and will start the app.
**Note**: If you choose not to use `main.sh`, but would rather just run all commands manually, please note that you will have to manually install submodules by running `git update submodules --init`. Without it, `static` will not be installed, and that is a required directory.
## Comprehensive Guide
Below will describe a comprehensive guide to install Ultraviolet on Linux machines.
To clone the repository, simply run the following command:
```sh
$ git clone https://github.com/titaniumnetwork-dev/Ultraviolet-Node --recursive
```
The `--recursive` flag will clone the repository and all submodules.
To begin work on the actual setup, cd into the repository. You can do so by running the following command:
```sh
$ cd Ultraviolet-Node
```
From here, you can update your submodules and install your dependencies. To do so, run the following command:
```sh
$ npm install
```
Finally, to start Ultraviolet, run the following command:
```sh
$ npm start
```
You can then find Ultraviolet on `http://127.0.0.1:8080`. If you would like to change the port UV will be running on, edit the last line in `index.mjs`.
Please note that UV will not function without HTTPS. If you are hosting on Replit or Heroku, this won't be a problem as they provide you with SSL/TLS by default and will automatically apply it to your instance, however if you are attempting to host UV on a different platform, such as a personal server, you **WILL** need to use HTTPS.
## Configuration
Configuring Ultraviolet is very simple. Simple descriptions of each configurable option are provided as a comment in the block below. More detailed documentation can be found just below mentioned block.
`uv.config.js`
```javascript
self.__uv$config = {
prefix: '/sw/', // Proxy url prefix
bare: '/bare/', // Bare server location
encodeUrl: Ultraviolet.codec.xor.encode, // URL Encoding function
decodeUrl: Ultraviolet.codec.xor.decode, // Decode URL function
handler: '/uv.handler.js', // Handler script
bundle: '/uv.bundle.js', // Bundled script
config: '/uv.config.js', // Configuration script
sw: '/uv.sw.js', // Service Worker Script
};
```
| Configuration | Options and Explanation |
| ------------- | ----------------------- |
| Prefix | The prefix is the prefix that you want users to see. Ex: `https://example.com/service.` The default prefix is `service`. |
| Bare | Bare Servers can run on directories. For example, if the directory was /bare/ then the bare origin would look like `http://example.org/bare/`. The bare origin is passed to clients. |
| encodeUrl| EncodeUrl is how you want the URL a proxy site's visitors has to be encoded. Options include `Ultraviolet.codec.base64.encode`, `Ultraviolet.codec.plain.encode`, or `Ultraviolet.codec.xor.encode`. It is recommended that you use `xor` or `base64` as it hides the queries your visitors are searching and visiting.
| decodeURL | DecodeUrl is how you want the url to be decoded. It is recommended you keep it the same as `encodeUrl`. |
| Handler | Handler is the path to the UV handler. The default name and path to this file is `static/uv/uv.handler.js`. |
| Bundle | Bundle is the path to the UV bundle file. The default name and path to this file is `static/uv/uv.bundle.js`. |
| Config | Config is the path to the UV config file. The default name and path to this file is `static/uv/uv.bundle.js`. |
| SW | SW is the path to the UV Service Worker script. The default name and path to this file is `static/uv/uv.sw.js`. |
## Static Files
Static files is the frontend for Ultraviolet. A standalone repository for it can be found [here](https://github.com/titaniumnetwork-dev/Ultraviolet-Static).
## Core Scripts
[Configuration](#configuration) mentions a few scripts that make up Ultraviolet. To get documentation for what each of the scripts do, check out the [documentation](https://github.com/titaniumnetwork-dev/Ultraviolet-Core) for them in their standalone repository.
