dot-json myfile.json user.email "john@example.com"
dot-json myfile.json foo..bar baz
dot-json myfile.json address '{"city":"Atlantis"}' --json-valuemyfile.json now looks like
{
"user": {

"city": "Atlantis"
}

If you want to change package.json, you can use npm’s pkg command instead of dot-json:
npm pkg get scripts.test
npm pkg set name=my-new-packagevar DotJson = require('dot-json');
var myfile = new DotJson('myfile.json');asynchronous
myfile.set('user.name', 'John Doe').set('user.email', 'john@example.com').save(function(){
console.log('saved');
});synchronous
myfile.set('user.name', 'John Doe').set('user.email', 'john@example.com').save();myfile.json now looks like
{
"user": {
"name": "John Doe",
"email": "john@example.com"
}
}asynchronous
myfile.get('user.name', function(value){
// value = 'John Doe'
console.log(value);
});synchronous
var value = myfile.get('user.name');
// value = 'John Doe'
console.log(value);asynchronous
myfile.delete('user.name').save(function(){
console.log('saved');
});synchronous
myfile.delete('user.name').save();myfile.json now looks like
{
"user": {
"email": "john@example.com"
