-# Hit Counter - Because Nothing Says Retro Like a Hit Counter
-
-[Remember Hit Counters? Well, They’re Back. And They’re Gloriously useless](https://datakra.sh/logs/remember-hit-counters-well-theyre-back-and-theyre-gloriously-useless), personal websites were as unique as fingerprints, and every site proudly flaunted a hit counter? It was the ultimate digital badge of honor—a glaring declaration of how many lost souls had wandered onto your site. Fast forward to now, and it turns out you can relive those glitzy days. Yup, hit counters are back, and they are as gloriously pointless as ever!
-
-## Why, Though?
-
-Why on Satans earth would anyone need a hit counter in 2024? Honestly, I haven't got the slightest idea. Most modern web metrics tools can provide far more detailed insights. But hey, who says everything needs to make sense? Sometimes, a little nostalgia is all you need to spice things up.
-
-## Features
-
-- **Custom Main Text and Secondary Text**: Because why settle for one when you can have two?
-- **Hit Counter**: See how many times the page is hit. It’s like a pissing contest, but for web traffic.
-- **Frame Option**: For when you want to make things a tad more "extra."
-- **Custom Colors**: Match your counter to your site's funky style.
-- **Custom Output**: jpg, png, webp, tiff, gif. High-tech stuff.
-
-## Requirements
-
-- Node.js 22.x or higher
-
-## Installation
-
-1. **Clone this fantastic repository**:
-
-    ```sh
-    git clone https://git.cyberwa.re/revengeday/hit-counter.git
-    ```
-
-2. **Navigate** to the project directory:
-
-    ```sh
-    cd hit-counter/node
-    ```
-
-3. **Install**:
-
-    ```sh
-    npm i
-    ```
-
-4. **Run devserver** to test it out locally:
-
-    ```sh
-    npm run dev
-    ```
-
-5. **Enjoy the Retro Vibes**: Access the script from your web browser or via `curl`:
-
-    ```sh
-    http://localhost:8000/
-    http://localhost:8000/hits # to see the count
-    http://localhost:8000/image # to see the image
-    http://localhost:8000/reset # to reset the count
-    ```
-
-## Configuration
-
-```ts
-// the config is defined in the HitCounterConfig interface
-interface HitCounterConfig {
-    siteId: number;
-    // path to the database file
-    counterDB: string;
-    // Background image URL for the counter display
-    backgroundImageUrl: string;
-    // local image path
-    imageFile: string;
-    backgroundCacheFile: string;
-    // Text settings to be displayed on the image
-    customText: string; // Main headline text
-    secondaryText: string; // Secondary descriptive text
-    textPositionX: number; // X position of the text
-    textPositionY: number; // Y position of the text
-    numberPositionX: number; // X position of the number
-    numberPositionY: number; // Y position of the number
-    fontSize: number; // Font size
-    fontFace: string; // Font face
-    borderWidth: number; // Border width
-    textColorRGB: RGBColor; // Text color
-    secondaryTextColorRGB: RGBColor; // Secondary text color
-    numberColorRGB: RGBColor; // Number color
-    frameColorRGB: RGBColor; // Frame color
-    drawFrame: boolean; // Whether to draw a frame around the counter
-}
-
-// currently only the ImageHitCounterRenderer is implemented, but this could be extended
-// to a canvas or html or whatever renderer
-```
-
-## Usage
-
-```ts
-import { HitCounter } from "./hit-counter";
-
-
-// default config
-defaultHitCounterConfig = {
-    siteId: 1,
-    counterDB: './hits.db',
-    backgroundImageUrl: 'https://datakra.sh/assets/example_counter.jpg',
-    imageFile: './example_counter.png',
-    backgroundCacheFile: './example_counter_bg.png',
-    customText: 'Hit Counter!',
-    secondaryText: 'Super cyber, super cool!',
-    textPositionX: 5,
-    textPositionY: 11,
-    numberPositionX: 170,
-    numberPositionY: 18,
-    fontSize: 10,
-    fontFace: 'fixed',
-    borderWidth: 3,
-    textColorRGB: { r: 253, g: 252, b: 1 },
-    secondaryTextColorRGB: { r: 0, g: 255, b: 0 },
-    numberColorRGB: { r: 255, g: 255, b: 255 },
-    frameColorRGB: { r: 255, g: 0, b: 0 },
-    drawFrame: true
-};
-
-// the default config will be used, but you can pass a custom config object as 
-// the first argument to the HitCounter constructor
-// e.g. const hitCounter = new HitCounter(customConfig);
-// the second argument is reserved for the renderer, but currently only the ImageHitCounterRenderer is implemented
-const hitCounter = new HitCounter();
-
-// increment the hit counter
-hitCounter.increment(); // async function
-
-// get the current hit count
-const count = await hitCounter.getCount();
-
-// get mime type
-const imageMimeType = hitCounter.getMimeType();
-
-// render the image
-const image = await hitCounter.render();
-
-// send to client however you like
-
-// reset the hit counter
-await hitCounter.reset();
-```
