# Resource Watch BigQuery Adapter
[![Build Status](https://travis-ci.com/resource-watch/adapter-bigquery.svg?branch=dev)](https://travis-ci.com/resource-watch/adapter-bigquery)
[![Test Coverage](https://api.codeclimate.com/v1/badges/383b48f860c6578ce531/test_coverage)](https://codeclimate.com/github/resource-watch/adapter-bigquery/test_coverage)
This repository is the microservice that implements the BigQuery adapter
functionality, which is exposed on the /bigquery endpoint.
## Dependencies
You will need [Control Tower](https://github.com/control-tower/control-tower) up and running - either natively or with Docker. Refer to the project's README for information on how to set it up.
The BigQuery adapter microservice 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/)
Execution using Docker requires:
- [Docker](https://www.docker.com/)
- [Docker Compose](https://docs.docker.com/compose/)
Dependencies on other Microservices:
- [Dataset](https://github.com/resource-watch/dataset/)
- [Converter](https://github.com/resource-watch/converter)
## Getting started
Start by cloning the repository from github to your execution environment
```
git clone https://github.com/resource-watch/adapter-bigquery.git && cd adapter-bigquery
```
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](#configuration-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
```
The endpoints provided by this microservice should now be available through Control Tower's URL.
### Using Docker
1 - Create and complete your `dev.env` file with your configuration. The meaning of the variables is available in this [section](#configuration-environment-variables). You can find an example `dev.env.sample` file in the project root.
2 - Execute the following command to run Control tower:
```
./adapter.sh develop
```
The endpoints provided by this microservice should now be available through Control Tower's URL.
## 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:
```
./adapter.sh test
```
## Configuration
### Environment variables
- PORT => TCP port in which the service will run
- NODE_PATH => relative path to the source code. Should be `app/src`
- MICROSERVICE_TOKEN =>
