# Places
|
||
|
||
**Places** is a web application written in [ReactJS](https://reactjs.org) and [NodeJS](https://nodejs.org) that, backed by the power of the [MariaDB Node Connector](https://github.com/MariaDB/mariadb-connector-nodejs) and [MariaDB platform](https://mariadb.com/products/mariadb-platform/), allows you to record all of your favorite locations!

## Environment and Compatibility <a name="compatibility"></a>
|
||
|
||
This application was created using the following techologies:
|
||
|
||
* [MariaDB](https://mariadb.com/products/mariadb-platform/)
|
||
* [React.js (v.16.11.0)](https://github.com/facebook/react/blob/master/CHANGELOG.md#16110-october-22-2019)
|
||
* [Node.js (v.12.x)](https://nodejs.org/docs/latest-v12.x/api/index.html)
|
||
* [NPM (v.6.11.3)](https://docs.npmjs.com/)
|
||
|
||
This application was tested on [macOS Mojave v.10.14.6](https://developer.apple.com/documentation/macos_release_notes/macos_mojave_10_14_6_release_notes).
|
||
|
||
## Overview <a name="overview"></a>
|
||
|
||
### Introduction to MariaDB <a name="intro-mariadb"></a>
|
||
|
||
[MariaDB platform](https://mariadb.com/products/mariadb-platform/) unifies [MariaDB TX (transactions)](https://mariadb.com/products/mariadb-platform-transactional/) and [MariaDB AX (analytics)](https://mariadb.com/products/mariadb-platform-analytical/) so transactional applications can retain unlimited historical data and leverage powerful, real-time analytics in order to provide data-driven customers with more information, actionable insight and greater value – and businesses with endless ways to monetize data. It is the enterprise open source database for hybrid transactional/analytical processing at scale.

||
|
||
### Using JSON in a relational database <a name="json-relational"></a>
|
||
|
||
[JSON](https://www.json.org) is fast becoming the standard format for data interchange and for unstructured data, and MariaDB Platform (in fact, all MariaDB versions 10.2 and later) include a range of [JSON supporting functions](https://mariadb.com/topic/json/).
|
||
|
||
The Places application uses only a **single table** for all location, and uses JSON to store more specific information based on the location type.
|
||
|
||
```sql
|
||
CREATE TABLE `Locations` (
|
||
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
|
||
`name` varchar(100) NOT NULL DEFAULT '',
|
||
`description` varchar(500) DEFAULT '',
|
||
`type` char(1) NOT NULL DEFAULT '',
|
||
`latitude` decimal(9,6) NOT NULL,
|
||
`longitude` decimal(9,6) NOT NULL,
|
||
`attr` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin DEFAULT NULL CHECK (json_valid(`attr`)),
|
||
PRIMARY KEY (`id`)
|
||
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8mb4;
|
||
```
|
||
|
||
For more information on how JSON can be used within MariaDB please check out this [blog post](https://mariadb.com/resources/blog/json-with-mariadb-10-2/)!

||
|
||
## Requirements <a name="requirements"></a>
|
||
|
||
This project assumes you have familiarity with building web applications using ReactJS and NodeJS technologies.
|
||
|
||
* Download and install [MariaDB](https://go.mariadb.com/download-mariadb-server-community.html?utm_source=google&utm_medium=ppc&utm_campaign=MKG-Search-Google-Branded-DL-NA-Server-DL&gclid=CjwKCAiAwZTuBRAYEiwAcr67OUBIqnFBo9rUBhYql3VZV_nhlSKzkwoUv7vhA6gwNdGoBSc2uWe7SBoCX_oQAvD_BwE).
|
||
* Download and install [NodeJS](https://nodejs.org/).
|
||
* git (Optional) - this is required if you would prefer to pull the source code from GitHub repo.
|
||
- Create a [free github account](https://github.com/) if you don’t already have one
|
||
- git can be downloaded from git-scm.org
|
||
|
||
## Getting started <a name="getting-started"></a>
|
||
|
||
In order to run the Places application you will need to have a MariaDB instance to connect to. For more information please check out "[Get Started with MariaDB](https://mariadb.com/get-started-with-mariadb/)".
|
||
|
||
In order to build and run the Places applications you will need to have NodeJS installed. You can find more information [here](https://nodejs.org/).
|
||
|
||
### Create the schema <a name="create-schema"></a>
|
||
|
||
Using CLI or SQL client run the following SQL command:
|
||
|
||
```sql
|
||
CREATE TABLE `Locations` (
|
||
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
|
||
`name` varchar(100) NOT NULL DEFAULT '',
|
||
`description` varchar(500) DEFAULT '',
|
||
`type` char(1) NOT NULL DEFAULT '',
|
||
`latitude` decimal(9,6) NOT NULL,
|
||
`longitude` decimal(9,6) NOT NULL,
|
||
`attr` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin DEFAULT NULL CHECK (json_valid(`attr`)),
|
||
PRIMARY KEY (`id`)
|
||
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8mb4;
|
||
```
|
||
|
||
### Grab the code <a name="grab-code"></a>
|
||
|
||
Download this code directly or use [git](git-scm.org) (through CLI or a client) to retrieve the code.
|
||
|
||
### Configure the code <a name="configure-code"></a>
|
||
|
||
**The gist;** Add a Google Maps API Key and database connection information to the code.
|
||
|
||
1. Once you've obtained a Google Maps API Key place add it to the code [here](src/client/src/components/MapContainer.js#L248).
|
||
|
||
```js
|
||
export default GoogleApiWrapper({
|
||
apiKey: ("ENTER_GOOGLE_API_KEY")
|
||
})(MapContainer)
|
||
```
|
||
|
||
2. Configure the MariaDB connection by [adding an .env file to the Node.js project](https://github.com/mariadb-corporation/mariadb-connector-nodejs/blob/master/documentation/promise-api.md#security-consideration).
|
||
|
||
Example implementation:
|
||
|
||
```
|
||
DB_HOST=<host_address>
|
||
DB_PORT=<port_number>
|
||
DB_USER=<username>
|
||
DB_PASS=<password>
|
||
DB_NAME=<database>
|
||
```
|
||
|
||
### Build the code <a name="build-code"></a>
|
||
|
||
Now that you have a copy of the code you're ready to build and run the project. However, before running the code it's important to point out that the application uses several Node Packages.
|
||
|
||
**Client-side**
|
||
|
||
Navigate to the [client directory](https://github.com/mariadb-corporation/Developer-Examples/tree/master/Places/src/client) and install the following packages:
|
||
|
||
- [google-maps-react](https://www.npmjs.com/package/google-map-react)
|
||
- [props-type](https://www.npmjs.com/package/props-type)
|
||
- [react](https://www.npmjs.com/package/react)
|
||
- [react-datepicker](https://www.npmjs.com/package/react-datepicker)
|
||
- [react-dom](https://www.npmjs.com/package/react-dom)
|
||
- [react-modal](https://www.npmjs.com/package/react-modal)
|
||
- [react-scripts](https://www.npmjs.com/package/react-scripts)
|
||
|
||
**Server-side**
|
||
|
||
Navigate to the [src directory](https://github.com/mariadb-corporation/Developer-Examples/tree/master/Places/src) and install the following packages:
|
||
|
||
- [body-parser](https://www.npmjs.com/package/body-parser)
|
||
- [concurrently](https://www.npmjs.com/package/concurrently)
|
||
- [express](https://www.npmjs.com/package/express)
|
||
- [mariadb](https://www.npmjs.com/package/mariadb) (the best database in world)
|
||
|
||
**Quick tip:** Executing the CLI command `npm install` within the [src](src) AND [client](src/client) folders will target the the relative `package.json` file and install all dependencies.
|
||
|
||
### Run the app <a name="run-app"></a>
|
||
|
||
Once you've pulled down the code and have verified that all of the required Node packages are installed you're ready to run the application! It's as easy as 1,2,3.
|
||
|
||
1. Using a command line interface (CLI) navigate to where to the [src directory](https://github.com/mariadb-corporation/Developer-Examples/blob/master/Places/src/) of Places.
|
||
|
||
<p align="center">

||
</p>
|
||
|
||
2. Run the command:
|
||
|
||
```bash
|
||
npm start
|
||
```
|
||
|
||
<p align="center">

|
||
</p>
|
||
|
||
3. Open a browser window and navigate to http://localhost:3000.
