# AcodeX-Server

> [!WARNING]
> It is recommended to avoid using this implementation. Instead, consider using [this alternative](https://github.com/bajrangCoder/acodex_server), which is lightweight, faster, and offers several advantages.

Cli for **AcodeX** Plugin

## Installation

Run `npm install -g acodex-server` for installing.

```
npm install -g acodex-server
```

## Usage

Run `axs` or `acodex-server` or `acodeX-server` to start server

```
axs
```

and `axs --help` for help

> More features coming soon...

:)
