This provides an API for updating the routes used by the router.

A Ruby on Rails application that manages the router database. Routes are stored in a mongo database using Mongoid as an ORM.

• mongoDB
• alphagov/router - to reload routes (optional in dev mode)

When running in development mode, this will ignore connection errors when triggering a reload of the router

bundle exec rails s

The app will then be available at http://localhost:3000/ (the port can be changed by passing a -p option to the command)

bundle exec rake

Information about the route data structure can be found in the router repository.

curl "http://router-api.example.com/routes?incoming_path=/foo"

This will return the corresponding route in JSON format.

The following will create/update a route entry:

curl http://router-api.example.com/routes -X PUT \
    -H 'Content-type: application/json' \
    -d '{"route": {"incoming_path": "/foo", "route_type": "exact", "handler": "backend", "backend_id": "foo"}}'

This will return details of the updated route in JSON format. If the route doesn't already exist, it will be created and a 201 status code returned. The backend_id must reference a backend that exists (see below).

On error a 400 status code will be returned, and the JSON response will include an "errors" key with more details.

curl "http://router-api.example.com/routes?incoming_path=/foo" -X DELETE

This will delete the corresponding route. If no route matches the JSON request, a 404 status code will be returned.

curl http://router-api.example.com/routes/commit -X POST

This will trigger a router reload and cause any changes to the route to take effect.

Backends represent an application that the router can route requests to. They are referenced by entries in the routes collection. Information about the backend data structure can be found in the router repository.

curl http://router-api.example.com/backends/foo

Will return the backend details in JSON format.

curl http://router-api.example.com/backends/foo -X PUT \
    -H 'Content-type: application/json' \
    -d '{"backend": {"backend_url": "http://foo.example.com/"}}'

This will update the backend_url for the backend with id 'foo'. The backend entry will be created if it doesn't already exist (and a 201 status code returned). The response will be a JSON representation of the updated backend.

On validation error a 400 status code will be returned, and the resulting JSON document will have an "errors" key with more details.

curl http://router-api.example.com/backends/foo -X DELETE

This will delete the backend with id 'foo'. This will only be allowed if the backend has no associated routes. A 400 status code will be returned if this is the case.
