TodoList CouchDB and Cloudant backend

Todo backend is an example of using the Kitura Swift framework for building a productivity app with a database for storage of tasks.

Quick start for local development:

You can set up your development environment and use Xcode 9 for editing, building, debugging, and testing your server application. To use Xcode, you must use the command line tools for generating an Xcode project.

Download Xcode 9
Download CouchDB and install
```
brew install couchdb
```

Clone the TodoList CouchDB repository

git clone https://github.com/IBM-Swift/TodoList-CouchDB

Generate an Xcode project
```
swift package generate-xcodeproj
```
Start CouchDB
```
couchdb
```
Run the Server target in Xcode and access http://localhost:8080/ in your browser to see an empty database.

Quick start on Linux

To build the project in Linux, you need to first install the Swift 4 toolchain.

Install the Swift 4 RELEASE toolchain
Install CouchDB:
```
sudo apt-get install couchdb
```

Clone the repository:

git clone https://github.com/IBM-Swift/TodoList-CouchDB

Compile the project
```
swift build
```
Run the server:
```
.build/debug/Server
```
Then access http://localhost:8080/ in your browser to see an empty database.

Deploying to IBM Cloud

Using the IBM Cloud Tools for Swift

The TodoList for Cloudant is deployable with a graphical user interface. Download:

IBM Cloud Application Tools for Swift

Deploy to IBM Cloud Button

You can use this button to deploy TodoList to your IBM Cloud account, all from the browser. The button will create the application, create and bind any services specified in the manifest.yml file and deploy.

Deploying Docker to IBM Cloud Container

For the following instructions, we will be using our Bash Script located in the root directory. You can attempt to complete the whole process with the following command:

   ./config.sh all <imageName>

Or, you can follow the step-by-step instructions below.

Install the Cloud Foundry CLI tool and the IBM Containers plugin for CF with the following
```
./config.sh install-tools
```
Ensure you are logged in with
```
./config.sh login
```
Build and run a Docker container with the following
```
./config.sh build <imageName>
```
To test out created Docker image, use
```
./config.sh run <imageName>
./config.sh stop <imageName>
```
Push created Docker container to IBM Cloud
```
./config.sh push-docker <imageName>
```
Create a bridge CF application to later bind to your container
```
./config.sh create-bridge
```
Create the Cloudant service and bind to your bridge CF application.
```
./config.sh create-db
```
Create a IBM Cloud container group where your app will live, binding it to your bridge CF application in the process
```
./config.sh deploy <imageName>
```
Afterwards, you can ensure Cloudant was bound correctly by viewing all credentials for your group
```
cf ic group inspect <imageName>
```
Optionally, if you want to populate your database with some sample data, run the following command with your image name:
```
./config.sh populate-db <imageName>
```

At this point, your app should be deployed! Accessing your apps route should return your todos, which should be [] if you did not populate the database.

Manually

IBM Cloud is a hosting platform from IBM that makes it easy to deploy your app to the cloud. IBM Cloud also provides various popular databases. Cloudant is an offering that is compatible with the CouchDB database, but provides additional features. You can use Cloudant with your deployed TodoList-CouchDB application.

Get an account for IBM Cloud
Download and install the Cloud Foundry tools:
```
cf api https://api.ng.bluemix.net
cf login
```
Be sure to run this in the directory where the manifest.yml file is located.

Create your Cloudant Service

cf create-service cloudantNoSQLDB Lite TodoListCloudantDatabase

Push your app
```
cf push
```
*Note This step will take 3-5 minutes
```
1 of 1 instances running

App started
```

Get the credential information:

cf env TodoListCloudantApp

Note you will see something similar to the following, note the hostname, username, and password:

"VCAP_SERVICES": {
  "cloudantNoSQLDB": [
     {
       "credentials": {
          "host": "465ed079-35a8-4731-9425-911843621d7c-bluemix.cloudant.com",
          "password": "<password is here>",
          "port": 443,
          "url": "https://465ed079-35a8-4731-9425-911843621d7c-bluemix:efe561fc02805bcb1e2b013dea4c928942951d31cd74cb2e01df3814751d9f45@465ed079-35a8-4731-9425-911843621d7c-bluemix.cloudant.com",
          "username": "<username is here>"
       },
     }]}

At this point, your app should be deployed! Accessing your apps route should return your todos, which should be [] to start.
