Mule4 example app. Able to convert recursive to flatten JSON structure and vice versa.
Service is able to:
- receives a recursive JSON structure and returns the flattened version;
- receives a flatten JSON structure and returns the recursive version.
- RAML 1.0
- Mule 4.4.0EE
Checkout from this repository and import into Anypoint Studio 7.X.X.
By default, service will run on http://localhost:8081
Following endpoints will be exposed:
| Methods | Urls | Action |
|---|---|---|
| GET | /console | Gives access to the generated documentation for the API |
| POST | /api/recursive | Receives a recursive data structure and returns the flattened one |
| POST | /api/flatten | Receives a flattened data structure and returnes the recursive one |
Example 1: GET http://localhost:8081/console/
Run in browser or REST client tool (e.g. Insomnia, Postman...) to open generated documentation for the API.
To be able to create a flat or recursive structure, our data must have pre-defined attributes that allow us to determine the location of a specific object.
These attributes are defined as 'parentLevelId' and 'childLevelId' in our case.
Example 2: POST http://localhost:8081/api/recursive
