boolify

Convert true/false strings to booleans

Example

var boolify = require('boolify')

boolify('true')
// true

boolify('false')
// false

boolify('A string')
// "A string"

var obj = boolify({
  t: 'true',
  f: 'false',
  s: 'Another string',
  n: 5
})
// {
//   t: true,
//   f: false,
//   s: 'Another string',
//   n: 5
// }

boolify('TRUE')
// true

boolify('tRuE')
// true

Usage

boolify is case-insensitive and will convert any string of "true" or "false" in to the appropriate boolean.

This is helpful for handling checkboxes in express' req.body

app.put('/users/:username', function(req, res) {
  console.log(req.body.someCheckbox) // 'true'
  req.body = boolify(req.body)
  console.log(req.body.someCheckbox) // true
})

boolify(object | string)

If provided an object, boolify will recursively convert all values.

var result = boolify({one: {fish: {two: {fish: 'true'}}}})
console.log(result.one.fish.two.fish)
// true

Install

With npm do:

npm install boolify
