- Svelte 3 Up and Running
- Want to learn Svelte 3 and how to build a Single-Page App (SPA) with it (and with this router)? Check out my book Svelte 3 Up and Running on Amazon.
- |
-
+# Frontend
-# Svelte app with svelte-spa-router
+This sub-project contains the SPA (Single Page Application) of the website.
-This is a project template for [Svelte 4](https://svelte.dev) apps that includes [svelte-spa-router](https://github.com/italypaleale/svelte-spa-router) for client-side routing, TypeScript, and Vite as bundler.
+We build the SPA before we serve it to the users to save processing power on the server.
-## About svelte-spa-router
+## Installation
-svelte-spa-router is a client-side router for Svelte 4 apps that leverages hash-based routing (i.e. stores the current view in the URL after the `#` symbol).
+Run the following command to build the sub-project:
-You can read more about the router, and the reasons why you might want to use hash-based routing (or not), in the [documentation](https://github.com/italypaleale/svelte-spa-router).
-
-## Get started
-
-Install the dependencies…
-
-```bash
-cd svelte-app
-npm install
```
-
-…then start a dev server using [Vite](https://vite.dev):
-
-```bash
-npm run dev
+pnpm run build
```
-Navigate to [http://localhost:5050](http://localhost:5050). You should see your app running. Edit a component file in `src`, save it, and reload the page to see your changes.
-
-You can add more routes by defining them in the [`src/routes.ts`](./src/routes.ts) file. More information can be found on the [documentation for svelte-spa-router](https://github.com/ItalyPaleAle/svelte-spa-router/blob/main/README.md).
-
-By default, the server will only respond to requests from localhost. To allow connections from other computers, edit the `vite` commands in package.json to include the option `--host 0.0.0.0`.
-
-If you're using [Visual Studio Code](https://code.visualstudio.com/) we recommend installing the official extension [Svelte for VS Code](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode). If you are using other editors you may need to install a plugin in order to get syntax highlighting and intellisense.
-
-## Building and running in production mode
-
-To create an optimized version of the app:
-
-```bash
-npm run build
-```
+## Main Technologies
-You can run the newly-built app with `npm run preview`.

+This sub-project handles all the logic of the Sunfounder Raspberry Pi.
+
+The system is broken down to 3 sub systems:
+- lidar - Handles the lidar scanner of the Raspberry Pi
+- messaging - Handles the websocket of the Raspberry Pi
+- movement - Handles the movement of the Sunfounder Raspberry Pi
+
+The system is then displayed by the `CarConsole`.
