This repository contains example code demonstrating how to use LunarCRUSH embeddable widgets.
$ python -m SimpleHTTPServer 5000
Open http://localhost:5000 in a browser
Widgets can be embedded using a standard iframe tag with a src endpoint of: https://lunarcrush-widgets.firebaseapp.com. Specific widgets can be rendered using one of the following url paths:
- /galaxy
- /news
- /social
- /metrics
- /wordcloud
- /candlestick
You will need to sign up for a LunarCRUSH free or PRO account and create an API key here to be able to render the widgets.
<iframe name="Galaxy Score" id="galaxy-score-widget" src="https://lunarcrush-widgets.firebaseapp.com/galaxy?key={API_KEY_HERE}&symbol=BTC&interval=1%20Week" frameborder="0" border="0" cellspacing="0" scrolling="no"></iframe>
- https://github.com/levid/lunarcrush-widget-example/blob/master/index.html
- https://github.com/levid/lunarcrush-widget-example/blob/master/widgets.html
It is possible to configure the widgets using url params appended to the iFrame src url. For example:
- ?key={API_KEY_HERE} - Required to render the widgets.
- ?symbol=BTC - Change the symbol that is displayed in the widgets.
- ?interval=1 Week - Change the time interval being displayed in the charts (default is 1 Week).
- ?price_correlation=true|false - Show a price line in addition to the selected metric (default = false)
- ?metric=galaxy_score - Change the timeseries metric being displayed (Metric widget only).
- ?animation=true|false - Show or hide component animations (default = true)
- ?theme={See themes section for instructions}
- ?scrolling=true|false (default = true) - Enable or disable scrolling on the widget inner content. Use this if you want to set scrolling=false on the iframe with a fixed height but still want to allow scrolling within the widget.
Theming is very basic at this point but it is possible to configure primary and secondary colors used throughout the widgets as well as line colors in the Metrics widget.
Dark theme example: https://lunar-widget-test.firebaseapp.com/widgets.html Light theme example: https://lunar-widget-test.firebaseapp.com/widgets-light.html
To use our default light or dark theme, simply pass "?theme=light" or "?theme=dark" in the querystring of the embed URL (light is the default theme used to render the widgets).
It is also possible to pass a custom theme object into each widget. Here is an example of our default light theme setup. Simply edit any of the color values to customize the theme to your needs and then serialize the object and append it to the query string of the embed URL (example below).
var theme = {
type: 'light',
common: { black: '#000', white: '#fff' },
background: { paper: '#fff', default: 'rgba(249, 249, 249, 1)' },

It is also possible to pass in your own custom stylesheet file to override page and component styles inside the widget iframe. This will need to be hosted on a public domain to make it accessible to the widget.
/* styles.css */
/* Include custom fonts */
@import url(https://fonts.googleapis.com/css?family=Roboto&display=swap);
/* Override global body styles */
html,
body {
margin: 0;
padding: 0;
overflow: hidden;
background-color: #0e1722;
color: #fff;
font-family: 'Roboto', sans-serif;
}
/* Override link colors */
a {
color: #69d8ee;
text-decoration: none;
}
/* Override specific UI element styles */
.loading-container {
display: flex;
align-items: center;

}
