#### Initialization
javascript
var DotJson = require('dot-json');
var myfile = new DotJson('myfile.json');
`#### Writing
asynchronous
javascript
myfile.set('user.name', 'John Doe').set('user.email', 'john@example.com').save(function(){
console.log('saved');
});
`synchronous
javascript
myfile.set('user.name', 'John Doe').set('user.email', 'john@example.com').save();
`myfile.json now looks like
json
{
"user": {
"name": "John Doe",
"email": "john@example.com"
}
}
`#### Reading
asynchronous
javascript
myfile.get('user.name', function(value){
// value = 'John Doe'
console.log(value);
});
`synchronous
javascript
var value = myfile.get('user.name');
// value = 'John Doe'
console.log(value);
`#### Deleting
asynchronous
javascript
myfile.delete('user.name').save(function(){
console.log('saved');
});
`synchronous
javascript
myfile.delete('user.name').save();
`myfile.json now looks like
json
{
"user": {
"email": "john@example.com"
}
}
