# Express-postgres-mapbox example

![Example screenshot](/screenshot.png)

## Starting

First, create and populate the db:

```

$ createdb express-postgres-mapbox-example

$ npm run db:init

```

Then create a `secrets.json` file with:

```json

{

    "DATABASE_USERNAME": "your database username",

    "DATABASE_PASSWORD": "your database password",

    "MAPBOX_ACCESS_TOKEN": "your mapbox access token"

}

```

Finally:

```

$ npm start

```

And visit http://localhost:3000!

## Storing GeoJSON inside the database

Since we need it just for storage and not for querying, the [`jsonb` postgres type][jsonb] is enough:

```js

function updateItineraryById({ id, geometry }) {

    return db

        .query(

            "UPDATE itineraries SET geometry = ($2)::jsonb WHERE id = $1 RETURNING *",

            [id, JSON.stringify(geometry)]

        )

        .then((result) => result.rows[0]);

}

```
