service-echo

JSON Echo Service with clean architecture based on Go-clean-template.

Service returns the JSON-document that was passed to it. When rewrite rules are active the document will be overwritten considering them.

• Overwriting recursion for JSON-documents & unit-tests
• Echo REST-HTTP & integration-tests
• Swagger Docs

Rewrite Rules

Rewrite rules are stored in config/config.yaml

rewriter:
  active: true
  rules:
    name: "pokemon"
    value: "pikachu"
    new: "bulbasaur"

To activate rewriter - set active field to true, deactivate -false.

• name and value represents field name and field value of document which should be overwritten
• new represents new field value for that pair

Example above will be rewritten like this:

"pokemon":"pikachu" -> "pokemon":"bulbasaur"

Pair of field name and field value will be found anywhere deep in document:

{
  "pokemon": "pikachu",
  
  "some_object": {
    "pokemon":"pikachu"
  },
  
  "another_object": {
    "in_object": {
      "pokemon":"pikachu"
    }
  },
  
  "some_array": [
    {
      "in_array": [
        {
          "pokemon": "pikachu"
        }
      ]
    }
  ]
}

result:

{
  "pokemon": "bulbasaur",
  
  "some_object": {
    "pokemon":"bulbasaur"
  },

  "another_object": {
    "in_object": {
      "pokemon": "bulbasaur"
    }
  },
  
  "some_array": [
    {
      "in_array": [
        {
          "pokemon": "bulbasaur"
        }
      ]
    }
  ]
}
