<br />

## Setup 🚀

You can create a new project using the `@pota/create` package.

```bash
npx @pota/create webpack my-webpack-app
```

<!--
During project creation, everything above this comment should _ideally_ be replaced with a `Quick Start` on how to run & build the project, referencing the project title in the heading, instead of the skeleton's.

## Standards 📒

This project follows the
[MediaMonks Frontend Coding Standards](https://github.com/mediamonks/frontend-coding-standards)

## Features 🔋

### Service Worker

The skeleton has opt-in support for
[service workers](https://developer.mozilla.org/en-US/docs/Web/API/Service_Worker_API/Using_Service_Workers)
through the help of [workbox](https://developers.google.com/web/tools/workbox/).

To get started, you can create `/src/service-worker.ts` file to customize workbox and its many
[modules](https://developers.google.com/web/tools/workbox/modules) .

> This is how an example service worker file could look like:

```ts
/// <reference lib="webworker" />

import { clientsClaim } from 'workbox-core';
import { precacheAndRoute } from 'workbox-precaching';

declare const self: ServiceWorkerGlobalScope;

clientsClaim();

// eslint-disable-next-line no-underscore-dangle
precacheAndRoute(self.__WB_MANIFEST);
```

Now, whenever you bundle your application for production, a `service-worker.js` file will be
generated.

As a last step, you need to make sure to register the service worker using the
`serviceWorkerRegistration.ts` module, see the comment in `main.ts` for more details.

### Deployment

#### Remote Sync

For simple deployments, when you just want to upload your files to a remote server, you can use the
`rsync` script.

Note: before using the `rsync` script, make sure to configure a host in in the "package.json"

```bash
npm pkg set config.host="github.com"
```
