There are many tools to lint and format json. This is a containerized api solution.
This allows the running of postman/curl with an unformatted json blob, and the returned output will be formatted.
Simply docker pull reskin89/jsonlinterapi and run the image, exposing a public port, to internal port 8400.
To run in its default configuration run:
make build-app image=YOURIMAGENAME port=EXTERNALPORT
Replace YOURIMAGENAME with what you'd like to name the docker image, and port with the external port you'd like to hit the api on. The application runs itself on port 8400.
There is also logging for simple reasons to see when and where requests come from and their methods. These are output to stdout so the docker logs command works quite well with it.
