miniQR is a micro HTTP service that generates QR codes on the fly.

This server is very small (~1MB docker image) and portable since it

runs anywhere Rust can compile for.
|
|
|
|

|
## Building a docker image
|
|
|
|
|
Just use the dockerfile provided in the root of the project.
|
|
|
|
|
|
|
|
|
|
## API Docs
|
|
|
|
|
Let's say you want a QR with this text in it: `fkpt`.
|
|
|
|
|
|
|
|
|
|
To get this QR, you will need to send a GET request to `http://miniqr_instance/fkpt`. That's it.
|
|
|
|
|
|
|
|
|
|
## Upscaling the QR image
|
|
|
|
|
Since the QR image that is provided is ridiculously small, you will need to upscale it
|
|
|
|
|
using your platform's GUI toolkit.
|
|
|
|
|
|
|
|
|
|
And I am guessing that your GUI toolkit is CSS, so here is a snippet for that:
|
|
|
|
|
|
|
|
|
|
```css
|
|
|
|
|
img.qrcode-image {
|
|
|
|
|
width: 400px;
|
|
|
|
|
image-rendering: pixelated; /* This line "unblurs" the qr code */
|
|
|
|
|
|
|
|
|
|
padding: 60px;
|
|
|
|
|
background: white;
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
```html
|
|
|
|
|
<img src='http://miniqr/aaa' class='qrcode-image'>
|
|
|
|
|
```
|
