@omrprks/jsonmerge

Small tool for merging json files

Just needed a quick re-usable script for merging json files (for container definitions -> task definitions for AWS ECS)

npm install -g @omrprks/jsonmerge

// main.json
{
  "name": "main",
  "version": 1
}
// another-one.json
{
  "name": "another-one"
}

$ jsonmerge main.json another-one.json
#=> Output: {"name":"another-one","version":1}

Alternatively you can nest the contents of a json file by specifying the property name (e.g. property:filename):

$ jsonmerge main.json anotherOne:another-one.json
#=> Output: {"name":"main","version":1,"anotherOne":{"name":"another-one"}}
