Micro API: mongodb API

This API uses named mongodb queried to create a API adapter into the Governance Graph.

It's implemented as a microservice that maps URL sub-paths to named mongodb queries.

The config/default.yaml is used to configure the chassis, specificially the 'mongdb' plugin.

The built-in "openapi" plugin is used to map /:query/ requests to the 'mongdb' operation.

Options

The "mongdb" options can be specified as a global config or within relevent the "openapi" definition.

mongdb:
  database: "example"
  host: "localhost"
  port: 27017
  username: "me"
  password: "secret"

The "database" refers to an external mongodb database. The "host" points to the hostname of mongodb instance. Alternatively, "hosts" points to an array of hostnames for a mongodb cluster. The "port" refers to the mongodb instance port.

openapi plugin

The chassis is configured by an OpenAPI definition. The "operationId" fields must be mapped to a valid plugin.

The "operationId" can be used in more than one path - which is different from the Swagger/Open API specification.

openapi:
  paths:
    /healthz:
      get:
        chassis:
          operationId: heartbeat
    /swagger:
      get:
        chassis:
          operationId: apidocs
    "/mongodb/example/:collection":
      get:
        chassis:
          operationId: mongdb
      post:
        chassis:
          operationId: mongdb
    "/mongodb/:collection/:id":
      get:
        chassis:
          operationId: mongdb
      post:
        chassis:
          operationId: mongdb
      put:
        chassis:
          operationId: mongdb

For example:

$ npm install && npm start
$ curl -v http://localhost:7001/mongodb/example/
