A simple Svelte app - crypto address to qrcode

Stand-alone live demo on Vercel

https://helper-crypto-address-qrcode.vercel.app

bb.set({text:"NPM package with Bombay Engineer Group"},3) in Web Inspector

Get started

Install the dependencies...

npx degit https://github.com/rutynka/helper-crypto-address-2-qrcode
cd helper-bar-board
yarn install

...then start Rollup:

yarn dev

Navigate to localhost:5000. You should see your app running. Edit a component file in src, save it, and reload the page to see your changes.

By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the sirv commands in package.json to include the option --host 0.0.0.0.

If you're using Visual Studio Code we recommend installing the official extension Svelte for VS Code. If you are using other editors you may need to install a plugin in order to get syntax highlighting and intellisense.

Import as Svelte Component with bindings this

npx degit sveltejs/template svelte-typescript-app
cd svelte-typescript-app
node scripts/setupTypeScript.js
yarn install
yarn add @rutynka/helper-crypto-address-2-qrcode
yarn dev
http://localhost:8080/

<script>
    export let name;

    import Crypto from '@rutynka/helper-crypto-address-2-qrcode'
    const ltc = new Crypto({target:document.body})

    ltc.set({
        text:'For the litecoin MWEB addresses cannot check account balance',
        show:true,
        timer:5000,
        icon:'https://cdn.rutynka.io/img/icon/ltc.svg',
        address:'ltcmweb1qqdwjvnm8l62l5a47aayh7yj7pg6kynfhvw6ucpfwwuqwsx4efeaqzqmgpn6w0mdsc5n767caxd256zk23053vgyxxkjwrqfndjj6m9wwuuqse923'
    })

Building and running in production mode

To create an optimised version of the app:

npm run build

You can run the newly built app with npm run start. This uses sirv, which is included in your package.json's dependencies so that the app will work when you deploy to platforms like Heroku.

Single-page app mode

By default, sirv will only respond to requests that match files in public. This is to maximise compatibility with static fileservers, allowing you to deploy your app anywhere.

If you're building a single-page app (SPA) with multiple routes, sirv needs to be able to respond to requests for any path. You can make it so by editing the "start" command in package.json:

"start": "sirv public --single"

Using TypeScript

This template comes with a script to set up a TypeScript development environment, you can run it immediately after cloning the template with:

node scripts/setupTypeScript.js

Or remove the script via:

rm scripts/setupTypeScript.js

Deploying to the web

With Vercel

Install vercel if you haven't already:

npm install -g vercel

Then, from within your project folder:

cd public
vercel deploy --name my-project
