transform-keys

Recursively transform object keys with a custom key transform strategy

Example

$3

``js
var transform = require("transform-keys");

var snake = {
a_snake_cased_key: {
foo_bar_baz: "qux",
null_value: null,
numbers: [1, 2, 3, 4]
}
};

var transformed = transform(snake, function (key) {
return key.replace(/_([a-z])/ig, function (_, $1) {
return $1.toUpperCase();
});
});

assert.deepEqual(transformed, {
aSnakeCasedKey: {
fooBarBaz: "qux",
nullValue: null,
numbers: [1, 2, 3, 4]
});

`

$3

`js
var transform = require("transform-keys");

var camelify = transform(function (key) {
return key.replace(/_([a-z])/ig, function (_, $1) {
return $1.toUpperCase();
});
});

var snakeify = transform(function (key) {
return key.replace(/([A-Z])/g, function (_, $1) {
return '_'+$1.toLowerCase();
});
});

var snake = {
a_snake_cased_key: {
foo_bar_baz: "qux",
null_value: null,
numbers: [1, 2, 3, 4]
}
};

var camel = {
aSnakeCasedKey: {
fooBarBaz: "qux",
nullValue: null,
numbers: [1, 2, 3, 4]
}
};


assert.deepEqual(camelify(snake), camel);
assert.deepEqual(snakeify(camel), snake);
