CircleCI Coverage Status semantic-release Commitizen friendly npm version

One of those missing lodash functions. Includes TypeScript definitions and Flow definitions (they aren't prefect, there are some edge cases...)

import mapShape from 'map-shape'
mapShape(
 {
 foo: 1,
 bar: '2',
 baz: 'hello',
 },
 {
 foo: (value, key, obj) => `${value} ${key} ${obj.baz}`,
 bar: value => parseInt(value),
 }
)
// outputs { foo: '1 foo hello', bar: 2 }

Each mapper function is called with three arguments:

• value - the value of the input property
• key - the key of the input property
• obj - the input object

If the input object is null, returns null. If the input object is undefined, returns undefined.

Works better with lodash/fp. Only passes the value to each mapper function.

import mapShape from 'map-shape/fp'
mapShape({
 foo: String,
 bar: parseInt,
})({
 foo: 1,
 bar: '2',
 baz: 'hello',
})
// outputs { foo: '1', bar: 2 }
