Nearby services API

An API focusing on services near to a specific search point.

Currently, it is used by connecting-to-services to provide services near to a lat/lon.

This app uses nhsuk/bunyan-logger. As such, a number of environment variables can be used, and in production, NEED to be set for the logging to work. Check out the README in that repo for additional information.

API Interface

There are two endpoints available:

• /open?latitude=$latitude&longitude=$longitude[&limits:results=$numberResults]
• /nearby?latitude=$latitude&longitude=$longitude[&limits:results=$numberResults]

All query string parameters are validated and return an informative message when incorrect.

Mandatory query string parameters:

• latitude - must be a valid latitude
• longitude - must be a valid longitude

Optional query string parameters:

• limits:results - the default and limits are defined in the config

Both endpoints return an object containing an array of pharmacies against a field called results e.g.

{
  results: [
  {
   ...
  },
  {
   ...
  }
  ]
}

Environment variables

Environment variables are expected to be managed by the environment in which the application is being run. This is best practice as described by twelve-factor.

For any env var that is required by the application to run and doesn't have a default require-environment-variables is used to throw an error and prevent the application from starting up. Rather than it getting to point somewhere later in the life cycle where it can't do something because there is no value for an env var it was relying on.

Variable	Description	Default
NODE_ENV	Node environment	development
LOG_LEVEL	Numeric log level	Depends on NODE_ENV
PORT	Server port	3001
ES_INDEX	Name of index in the ElasticSearch image	pharmacies
ES_HOST	Name of ElasticSearch host	es
ES_PORT	The port used by ElasticSearch	27017
RESULT_LIMIT_OPEN_MAX	The maximum number of open results	10
RESULT_LIMIT_NEARBY_MAX	The maximum number of nearby results	10

Running the application

Start by cloning the repo and all submodules i.e. git clone https://github.com/nhsuk/nearby-services-api.git && cd profiles/ && git submodule update --init --recursive

Next, have a look at the scripts for getting the application running scripts

Then click here to see results (if all went well).

To run the full stack application including the front end use the docker-compose-full-stack.yml, i.e. docker-compose -f docker-compose-full-stack.yml down -v docker-compose -f docker-compose-full-stack.yml up --build --force-recreate

Changing the time

This stack supports an environment variable to change the current time in the API. Sample format to set: export DATETIME=2017-02-15T03:30:00 And to remove: unset DATETIME

FAQ

1. When I run docker-compose I get errors about packages missing. Often it seems to be Nodemon.

• This could well be because the volume used by the service has previously been mounted when NODE_ENV was set to production. Try running docker-compose down -v which removes all the things created by the docker-compose up command, including volumes (with the -v flag). For test, run docker-compose -f docker-compose-tests.yml down -v

Contributing to the application

Make your changes but before you commit them run the tests.
