쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

$ npm install -g yo generator-cardkit

package.json에 명시된 라이브러리들을 내려받아 설치합니다.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

# CardKit

> A simple, powerful and fully configurable image editor for web browers and servers. Optional UI included.

CardKit has three main parts:

- [`CardKit`](#cardkit): The core library, that manages and maintains the configuration object which defines the structure and options of a card
- [`CardKitDOM`](#cardkitdom): A DOM renderer, that takes an instance of CardKit and renders either a standalone image, or a pre-packaged UI for editing the image
- [`CardKitServer`](#cardkitserver): A server renderer, that allows you to take an instance of CardKit and render it into an image on a Node.js server

Additionally, a base class allows you to create your own renderers. See more in the [Custom Renderers](#custom-renderers) section.

## Installation

`$ npm install cardkit --save`

## Usage

CardKit requires a configuration object in order to render an image. Each renderer (CardKitDOM and CardKitServer) uses this configuration and converts it into an output. Below are simple implementations for CardKit depending on your use case.

In addition to these, you may also want to try the [CardKit Yeoman Generator](https://www.github.com/times/generator-cardkit), which can help you scaffold an entire project in just a few moments. It brings with it the latest version of CardKit, a recommended directory structure, and a build process that helps you get your CardKit project deployed. There is also a [JSFiddle](https://jsfiddle.net/chrishutchinson/16tLs2ta/) that you can fork and edit for quick in-browser testing without touching the command line.

### Previous versions

For **version 1**, see the [`v1-main`](https://github.com/chrishutchinson/cardkit/tree/v1-main) branch.

For **version 2**, see the [`v2-main`](https://github.com/chrishutchinson/cardkit/tree/v2-main) branch.

#### Yeoman generator

$ npm install -g yo generator-cardkit
    $ yo cardkit

#### Browser with Webpack / Browserify usage

```js
// Load CardKit and CardKit DOM
const CardKit = require("cardkit");
const CardKitDOM = require("cardkit/dom");

// Base configuration object - see `./examples/configurations` for examples
var configuration = {};

// Optional themes object - see `./examples/configurations` for examples
var themes = {};

// Optional layouts object - see `./examples/configurations` for examples
var layouts = {};

// Initialise CardKit
var cardkit = new CardKit(configuration, {
  themes: themes,
  layouts: layouts,
});

// Initialise Renderer
var renderer = new CardKitDOM(cardkit);

// To render the card only (with optional theme / layout overrides)
renderer.renderCard("card", {
  theme: "Alt",
  layout: "Square",
});

// OR To render the editing UI
renderer.renderUI("card");
```

#### Browser with `<script>` tag usage

```html

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.3.2/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.3.2/react-dom.min.js"></script>

<script
  type="text/javascript"
  src="https://cdn.rawgit.com/chrishutchinson/cardkit/v2.0.6/dist/cardkit.js"
></script>
<script
  type="text/javascript"
  src="https://cdn.rawgit.com/chrishutchinson/cardkit/v2.0.6/dist/dom.js"
></script>

<div id="card"></div>

<script type="text/javascript">
  // Base configuration object - see `./examples/configurations` for examples
  var configuration = {};

// Optional themes object - see `./examples/configurations` for examples
  var themes = {};

// Optional layouts object - see `./examples/configurations` for examples
  var layouts = {};

// Initialise CardKit
  var cardkit = new CardKit(configuration, {
    themes: themes,
    layouts: layouts,
  });

// Initialise Renderer
  var renderer = new CardKitDOM(cardkit);

// To render the card only (with optional theme / layout overrides)
  renderer.renderCard("card", {
    theme: "Alt",
    layout: "Square",
  });

// OR To render the editing UI
  renderer.renderUI("card");
</script>
```

#### Server usage

```js
// Require CardKit and CardKitServer
const CardKit = require("cardkit");
const CardKitServer = require("cardkit/server");

// Base configuration object - see `./examples/configurations` for examples
const configuration = {};

// Initialise CardKit
const cardkit = new CardKit(configuration);

// Initialise Renderer
var renderer = new CardKitServer(cardkit);

// Render to image
renderer
  .renderToImage(2)
  .then((image) => {
    // Do what you want with the image here...
    console.log('<img src="data:image/png;base64,' + image + '" />');
    process.exit();
  })
  .catch((e) => {
    console.log("[ERR]", e);
    process.exit();
  });
```

## APIs

### CardKit

#### `new CardKit(configuration, options)`

> Initialisation. Pass in a required configuration object, and optional themes, templates and layouts

#### `cardkit.updateConfiguration(configuration, options, rerender)`

> Updates the configuration in your instance of CardKit. Can optionally rerender with a flag if previously rendered (supported in CardKitDOM).

#### `cardkit.computeConfiguration(options)`

> Computes a configuaration object, optionally accepting a named template, theme and layout. These get merged into the base configuration and returned.

### CardKitDOM

#### `new CardKitDOM(cardkit)`

> Accepts an instance of CardKit and initialises the renderer

#### `cardkit.renderUI(id, overrides)`

> Renders the include user interface to the specified DOM element

#### `cardkit.renderCard(id)`

> Renders just the card in it's SVG form to the specified DOM element

#### `cardkit.rerender()`

> Will re-render the existing UI or card

#### `cardkit.download(scale, element)`

> Downloads the image to your local machine. Accepts a scale (default=2), and an element to grab from. If not provided it will fall back to the existing card being rendererd (if `renderCard()` was used).

### CardKitServer

#### `new CardKitDOM(cardkit)`

> Accepts an instance of CardKit and initialises the renderer

#### `cardkit.renderToString()`

> Renders the card to a HTML string (e.g. `<svg...></svg>`)

#### `cardkit.renderToImage(scale)`

> Renders the card to an image returning a Promise containing the image as a base64 string

## Custom Renderers

A base class `CardKitRenderer` allows you to create your own renderer for CardKit. For example, CardKitDOM currently uses SVG to create the card, and React to render the UI. You may, however, wish to render your card using HTML canvas, or build a UI using Vue.js. Creating a custom renderer is a good way to achieve this. Below is a brief example of how you might achieve this:

```js
class CardKitCanvas extends CardKitRenderer {
  renderCard() {
    // Canvas-specific code here
  }

rerender() {
    // A method that `CardKit` calls if the base configuration object is updated
    // Handle an update to the base configuration, e.g. you may want to re-render the canvas element here
  }

yourCustomMethod() {
    // You can implement any custom methods here, for example you may wish to expose or manipulate the <canvas> element for other users to take advantage of
  }
}

const cardkit = new CardKit(configuration);

const renderer = new CardKitCanvas(cardkit);

renderer.yourCustomMethod();
```

## Custom Fonts

CardKit allows you to load in custom fonts for use on your cards, see the Wiki for details. These need to be encoded into base64 format.

_If you wish to use a Google font, you can use the [googlefontcss64](https://www.npmjs.com/package/googlefontcss64) library to generate a base64 version of any Google font. You can use [this](https://gist.github.com/chrishutchinson/4a9f7bffddfec376e9d71e8666d5955d) Node.js script to get all the details you need._

Once you have the base64 encoded version of your font, you can register it in your configuration object, like so:

```js
var configuration = {
  // ...
  fonts: {
    MyCustomFontName: base64encodedFont,
  },
  layers: {
    text: {
      fontFamily: "MyCustomFontName",
    },
  },
  // ...
};
```

If you need to provide a specific format for your font, you can do the following:

```js
var configuration = {
  // ...
  fonts: {
    MyCustomFontName: {
      src: base64encodedFont,
      format: "woff",
    },
  },
  layers: {
    text: {
      fontFamily: "MyCustomFontName",
    },
  },
  // ...
};
```

## Running locally

CardKit currently requires Node.js 14, which you can install using `nvm` and running:

$ nvm use

To run a sample UI locally, run: `$ npm start`

You can optionally pass a port like so: `$ npm start -- --port=8080`

## Tests

To trigger the test suite, run `$ npm run test`
