Project Components

Firebase

The above config may be missing as it is part of .gitignore, the file looks like:

export const exampleConfig = {
    projectId: "",
    messagingSenderId: "",
    appId: "",
    apiKey: "",
    authDomain: "",
    databaseURL: "",
    storageBucket: "",
    measurementId: ""
};

Additionally, there is an set_env.sh which you may set your hosting, firebase variables to generate .env files, set the Firebase environment variables etc. For those times when Routify misbehaves, there is also a kill_ports.sh which as the name suggests, will provide a menu of applications using ports for you to kill easily.

Overview of Svelte Components

Svelte JsQRScanner

The Svelte component is located in ./routify/src/pages/_components/JsQRScanner.svelte.

<script lang="ts">
    import Scanner from "./JsQRScanner.svelte";
</script>

<section id="Scanner" class="px-2 py-2 bg-white-200 md:py-24">    
    <Scanner />
</section>

You may want to expose additional events to capture the scanned text. Currently it outputs to:

<div class="FlexPanel form-field-input-panel">
    <textarea
        id="scannedTextMemo"
        class="textInput form-memo form-field-input textInput-readonly"
        rows="3"
        readonly
    />
</div>

Firebase Cloud Functions

The Cloud Functions portion of the repo contains code for managing Twilio inbound and outbound voice and SMS, Sendgrid, and Slack of which could be used for a scalable robo-dialer system. This system is discussed in its own repo, however some information can be found here. Please be considerate, this system was used with individuals who had previously consented to being contacted.

Setup Hosting

This template requires just the hosting file to set up, however, if your application includes other Firestore/Hosting features you may want to update the second configuration helper.

  • Update Firebase config routify/src/firebase/config.ts
  • Update Firebase config settings in ./scripts/set_env.sh

After you have your config.ts sorted out, the following should work.

cd routify && npm i && npm run build && npm run dev

Visit https://localhost:5000

Enjoy!
