# ethermap 

> This is very much a janky _earlydays_ project. All help is welcome!

An interactive map tool. A tool for collaborative planning on maps. Anyone can create new maps, and add, modify and delete locations on any map.

## Install

Ethermap is built in JavaScript (soz) using NodeJS. To install you can do so by running the following commands.

To install all dependencies for the front and backend :
```sh 
$ npm install
```
You will then need to create a `.env` file in the root folder. There is a `.env.template` that you can copy as a guide. For a dev server you can simply copy and paste the template leaving it as is.

Then migrate the database structure :
```sh 
$ npm run migrate:latest
```

Then you should be able to run the dev server :
```sh 
$ npm run dev
```

You should now be able to access ethermaps on [http://localhost:3000](http://localhost:3000/) (or whichever port you configured in your `.env` file).

## Tech

### Backend

Backend is running on [express.js](https://expressjs.com/) with [ViteExpress](https://github.com/szymmis/vite-express) bridging the gap between the fron and backends.

Database models, and queries are handled by [objection.js](https://vincit.github.io/objection.js/) ORM built on top of [knex](https://knexjs.org/). During dev the database defaults to an Sqlite3 db, and then during production it will be able to handle whichever database you choose. For now it has only been setup to work with PostgreSQL.

Live data is shared with the client using [socket.io](https://socket.io/).

Tests are written with [AVA](https://github.com/avajs/ava) and route testing uses [supertest](https://github.com/ladjs/supertest).

### Frontend

Frontend is an SPA using [lit](https://lit.dev/) element, and some [utilities](https://github.com/thepassle/app-tools) by [Pascal Schilp](https://github.com/thepassle).

Map rendering is done with [leaflet](https://leafletjs.com/).

Live rendering of users is done with [socket.io-client](https://socket.io/docs/v4/client-api/).

For the developer environment and future building, the frontend is managed by [Vite](https://vitejs.dev/).

## Desires

Minimal viable functionality for this project is the following :

- Anyone can create a map
- Anyone can create, modify and delete points on a map that contain at least
    - name of point
    - notes on said point
- Everyone can see current users _live_
    - users can choose their name
    - users can choose their cursor colour
    - user data should be remembered across visits

Things that ethermap should/could do in the future :

- points
    - edits are all recorded
- users
    - users can chat
    - users can also draw polygons and make labels that are not necessarily "points of interest"
- notes
    - notes should be rich
    - note updates should also be "live"
    - notes should be attributed to users who wrote/edited them
- _osmAnd Sync!_
