Dottie helps you easily (and without sacrificing too much performance) look up and play with nested keys in objects, without them throwing up in your face.
npm install dottie
For detailed usage, check source or tests.
Gets nested value, or undefined if unreachable, or a default value if passed.
var values = {
some: {
nested: {
key: 'foobar';
}
},
'some.dot.included': {
key: 'barfoo'
}
}
dottie.get(values, 'some.nested.key'); // returns 'foobar'
dottie.get(values, 'some.undefined.key'); // returns undefined
dottie.get(values, 'some.undefined.key', 'defaultval'); // returns 'defaultval'
dottie.get(values, ['some.dot.included', 'key']); // returns 'barfoo'Note: lodash.get() also works fine for this
Sets nested value, creates nested structure if needed
dottie.set(values, 'some.nested.value', someValue);
dottie.set(values, ['some.dot.included', 'value'], someValue);
dottie.set(values, 'some.nested.object', someValue, {
force: true // force overwrite defined non-object keys into objects if needed
});Transform object from keys with dottie notation to nested objects
var values = {
'user.name': 'Gummy Bear',
'user.email': '[email protected]',
'user.professional.title': 'King',
'user.professional.employer': 'Candy Mountain'
};
var transformed = dottie.transform(values);
/*
{
user: {
name: 'Gummy Bear',
email: '[email protected]',
professional: {
title: 'King',
employer: 'Candy Mountain'
}
}
}
*/var values = {
'user_name': 'Mick Hansen',
'user_email': '[email protected]'
};
var transformed = dottie.transform(values, { delimiter: '_' });
/*
{
user: {
name: 'Mick Hansen',
email: '[email protected]'
}
}
*/var object = {
a: 1,
b: {
c: 2,
d: { e: 3 }
}
};
dottie.paths(object); // ["a", "b.c", "b.d.e"];0.3.1 and up ships with dottie.memoizePath: true by default, if this causes any bugs, please try setting it to false
