@small-tech/svelte-nano-donate

A Nano donation component built using Svelte.

⯈ Live demo

Note: you can use this component in any web project, you do not need to use Svelte yourself.

Install

npm i @small-tech/svelte-nano-donate

Use (in Svelte apps)

Simply import and use the component.

All you need to use the component is the Nano address you want to receive donations into:

<script>
  import Donate from '@small-tech/svelte-nano-donate'
</script>

<Donate address=nano_1hfmyyjtm4muiudw1m8dz54jry13jx8xykp9kz1mx3uqe4dtsb3yrdkjgy6g/>

You can also customise the component by specifying properties like the initial amount and currency that’s displayed. And you even specify a theme to customise how the component looks:

<script>
  import Donate from '@small-tech/svelte-nano-donate'
</script>

<main>
  <Donate
    amount=5
    currency=usd
    address=nano_1hfmyyjtm4muiudw1m8dz54jry13jx8xykp9kz1mx3uqe4dtsb3yrdkjgy6g
    theme={{colour: '#0062cc'}}
  />
</main>

Here’s a live demo of this example built using SvelteKit (source code).

The colour value specified here will be used for the text. Also, the border-colour of form elements will automatically be calculated as a lighter tint of this colour, unless you specify that property explicitly.

Please make sure you check the contrast ratio of the colours you choose for accessibility. You can do so using Lea Verou’s online contrast ratio tool or, if you want to use an eyedropper tool to sample colours, a native app for your platform like Daniel Foré’s excellent Harvey on elementary OS).

The component comes with automatic dark mode support.

For the full list of theme properties, please see the Theming section.

Use (in non-Svelte apps)

You can require() or import() the component in your projects as it is simply a regular JavaScript class.

To use it, instantiate the class and pass it an options object that contains the DOM element that you want the class to bind to any properties you want to include (only the address property is required). The plain HTML and JavaScript snippet below is functionally equivalent to the Svelte version, above.

<main>
  <div id='nano-donate'></div>

  <script type='module'>
    import NanoDonate from '@small-tech/svelte-nano-donate'

    const nanoDonate = new NanoDonate({
      target: document.getElementById('nano-donate'),
      props: {
        amount: 5,
        currency: 'usd',
        address: 'nano_1hfmyyjtm4muiudw1m8dz54jry13jx8xykp9kz1mx3uqe4dtsb3yrdkjgy6g',
        theme: {colour: '#4A90E2'}
      }
    })
  </script>
</main>

This example is included in the example/ folder. Run it in a local server (e.g., using Site.js) to see it in action.

Theming

By default, you get a theme with light and dark modes.

You can also apply an entirely custom theme to the component by passing an object to the theme property.

The list of valid colour names for a custom theme object are shown here and they map to the CSS variables used in the component:

If you don’t explicitly pass a custom border-colour value, it will be calculated automatically from the value of the colour property. Note that for this automatic calculation to succeed, you must specify the value of the colour property in either rgb(a) or hex format (not as a CSS colour name).

Please make sure you check the contrast ratio of the colours you choose for accessibility. You can do so using Lea Verou’s online contrast ratio tool or, if you want to use an eyedropper tool to sample colours, a native app for your platform like Daniel Foré’s excellent Harvey on elementary OS).
