        # 📇 QR Code

Generate QR codes in Deno, as base64-encoded images, completely dependency-free and requires no binary.

This is a port of [zenozeng/node-yaqrcode](https://github.com/zenozeng/node-yaqrcode), which itself is a port of the QR code generator in the d-project.

## ⭐ Getting started

```ts

import { qrcode } from "https://deno.land/x/qrcode/mod.ts";

const base64Image = qrcode("bitcoin:ADDRESS?amount=0.5&label=ORDER"); // data:image/gif;base64,...

```

![QR code](https://upload.wikimedia.org/wikipedia/commons/thumb/d/d0/QR_code_for_mobile_English_Wikipedia.svg/240px-QR_code_for_mobile_English_Wikipedia.svg.png)

You can also add a custom size by specifying `size` in the second parameter:

```ts

const fixedSizeImage = await qrcode("bitcoin:ADDRESS?amount=0.5&label=ORDER", { size: 500 });

```

### CLI with [DPX](https://github.com/denorg/dpx)

After [installing DPX](https://github.com/denorg/dpx), you can directly use the CLI using the `dpx` command:

```bash

dpx qrcode 

```

### CLI

Alternatively, you can use it directly from the CLI by using `deno run`:

```bash

deno run https://deno.land/x/qrcode/cli.ts 

```

You can also install it globally using the following:

```bash

deno install https://deno.land/x/qrcode/cli.ts

```

Then, the package is available to run:

```bash

qrcode 

```

## 👩‍💻 Development

Run tests:

```bash

deno test

```

### Notes

- To support typeNumber 40, use the `RS_BLOCK_TABLE` from [davidshimjs/qrcodejs](http://davidshimjs.github.io/qrcodejs/)

- To support UTF-8, use the code from [davidshimjs/qrcodejs](http://davidshimjs.github.io/qrcodejs/)

- Returns a base64-encoded image URL
