# Control Tower API Gateway
A development-only API Gateway tool
[![Build Status](https://travis-ci.com/resource-watch/control-tower.svg?branch=main)](https://travis-ci.com/resource-watch/control-tower)
[![Test Coverage](https://api.codeclimate.com/v1/badges/6998e7a532fb2d138ca3/test_coverage)](https://codeclimate.com/github/resource-watch/control-tower/test_coverage)
## Dependencies
Control Tower is built using [Node.js](https://nodejs.org/en/), and can be executed either natively or using Docker,
each of which has its own set of requirements.
Native execution requires:
- [Node.js](https://nodejs.org/en/)
- [Yarn](https://yarnpkg.com/)
- [MongoDB](https://www.mongodb.com/)
Execution using Docker requires:
- [Docker](https://www.docker.com/)
- [Docker Compose](https://docs.docker.com/compose/)
## Getting started
Start by cloning the repository from github to your execution environment
```
git clone https://github.com/resource-watch/control-tower.git && cd control-tower
```
After that, follow one of the instructions below:
### Using native execution
1 - Set up your environment variables. See `dev.env.sample` for a list of variables you should set, which are described
in detail in [this section](#environment-variables) of the documentation. Native execution will NOT load the `dev.env`
file content, so you need to use another way to define those values
2 - Install node dependencies using Yarn:
```
yarn install
```
3 - Start the application server:
```
yarn start
```
Control Tower should now be up and accessible. To confirm, open [http://localhost:9000](http://localhost:9000/) (
assuming the default settings) on your browser, which should show a 404 'Endpoint not found' message.
### Using Docker
1 - Create and complete your `dev.env` file with your configuration. The meaning of the variables is available in
this [section](#documentation-environment-variables). You can find an example `dev.env.sample` file in the project root.
2 - Execute the following command to run Control tower:
```
./controlTower.sh develop
```
3 - It's recommended to add the following line to your `/etc/hosts` (if you are in Windows, the hosts file is located
in `c:\Windows\System32\Drivers\etc\hosts` and you'll need to 'Run as administrator' your editor):
```
mymachine <yourIP>
```
Control Tower should now be up and accessible. To confirm, open [http://mymachine:9000](http://mymachine:9000/) on your
browser, which should show a 404 'Endpoint not found' message.
## Testing
There are two ways to run the included tests:
### Using native execution
Follow the instruction above for setting up the runtime environment for native execution, then run:
```
yarn test
```
### Using Docker
Follow the instruction above for setting up the runtime environment for Docker execution, then run:
```
./controlTower.sh test
```
## Documentation
### Environment variables
Core Variables
- PORT => The port where control-tower listens for requests. Defaults to 9000 when not set.
- NODE_ENV => Environment variable of nodejs. Required.
- NODE_PATH => Required value. Always set it to 'app/src'.
- PUBLIC_URL => Base Application URL. It must be the public domain of your Control Tower instance, and it's used to
compose account links. It you are offering a local OAuth provider it's a required field. This URL also needs to be
configured as an acceptable callback on the OAuth provider settings.
