[![npm][npm-badge]][npm-url]

trail-hapi-server is a ready to use [Hapi][hapi] server with the trail-hapi-plugin registered.

It also provides a local instance of [Swagger UI][swagger-ui] to easily check the REST API documentation.

## Install

To install via npm:

    npm install @nearform/trail-hapi-server

## Usage

    npx run trail-hapi-server

This will start a server on `localhost:8080`. Swagger UI documentation is accessible at `http://localhost:8080/documentation/`.

## Configuration

The server looks for the following environment variables:

-   `TRAIL_DB_HOST`: The hostname for the trail database.
-   `TRAIL_DB_PORT`: The port number for the trail database.
-   `TRAIL_DB_NAME`: The name of the trail database.
-   `TRAIL_DB_USERNAME`: The username for the trail database.
-   `TRAIL_DB_PASSWORD`: The password for the trail database.
-   `TRAIL_DB_POOL_SIZE`: The size of the trail DB pool.
-   `TRAIL_DB_TIMEOUT`: The trail database idle timeout, in milliseconds.
-   `TRAIL_HTTP_HOST`: The hostname the HTTP server is bound to.
-   `TRAIL_HTTP_PORT`: The port the HTTP server is bound to.
-   `TRAIL_LOG_LEVEL`: The logging level; defaults to `warn`.
-   `TRAIL_DISABLE_REST_API`: Switch indicating whether to disable the REST API.
-   `TRAIL_DISABLE_GRAPHQL`: Switch indicating whether to disable the graphql endpoint.

These can also be defined using a `.env` file.

The server also takes the following command line options:

-   `--dbHost <host>`: Set the database host name; defaults to `localhost`.

-   `--dbName <name>`: Set the database name; defaults to `trails`.

-   `--dbPassword <password>`: Set the database password; defaults to `postgres`.
-   `--dbPoolsize <size>`: Set the database pool size; defaults to `10`.
-   `--dbTimeout <ms>`: Set the database pool timeout, in milliseconds; defaults to `30000`.
-   `--httpHost <host>`: Set the HTTP hostname; defaults to `localhost`.
-   `--httpPort <port>`: Set the HTTP port; defaults to `8080`.
-   `--logLevel <level>: Set the logger level; defaults to `warn\`.
-   `--noRESTAPI`: Switch to disable the REST API.
