A basic example creating a Koa modular application + MongoDB.

Read the post here about this repository.

Quick start

# install dependencies
$ npm install

# serve with hot reload at localhost:3000
$ npm run dev

# build for production and launch server
$ npm start

• uuid - Simple, fast generation of RFC4122 UUIDS..
• cross-env - Run scripts that set and use environment variables across platforms

Notes

1. During the development, use: $ npm run dev

2. backpack is used to watch and build the application, so you can use the latest ES6 features (module syntax, async/await, etc.).

3. MongoDB may fail in Ubuntu 18.04 as of 7/10/2018, to fix it, follow the guide from Mongo official site.

Step 1:

`$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4`

Step 2:

`$ echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list`

Step 3:

`$ sudo apt-get update`

Step 4:

`$ sudo apt-get install -y mongodb-org=4.0.2 mongodb-org-server=4.0.2 mongodb-org-shell=4.0.2 mongodb-org-mongos=4.0.2 mongodb-org-tools=4.0.2`

Step 5:

`$ sudo service mongod start`

Step 6:

```
$ sudo service mongod status

4. NodeJS and NPM may fail in Ubuntu 18.04 as of 7/10/2018, to fix it:

Step 1 - Try remove the npm first:

```
$ sudo apt-get remove nodejs
$ sudo apt-get remove npm
```

Check if npm or node folder still exist, delete it if you found them

```
$ which node
$ which npm
```

Step 2 - reinstall NodeJS:

```
$ curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
$ sudo apt-get install -y nodejs
```

Check if npm and node was installed and you're ready to use node.js

```
$ node -v
$ npm -v
```
