This can be done one of two ways, globally or per-project/directory:

Globally

Install:

npm install --global git-json-merge

Add to ~/.gitconfig:

[core]
    attributesfile = ~/.gitattributes
[merge "json"]
    name = custom merge driver for json files
    driver = git-json-merge %A %O %B

Create ~/.gitattributes:

*.json merge=json

Single project / directory

Install:

npm install git-json-merge --save-dev

Update git config:

git config merge.json.driver "$(npm bin)/git-json-merge %A %O %B"
git config merge.json.name "custom merge driver for json files"

Add the same .gitattributes where desired and commit. Note .gitattributes is only used after committed.
