Description

Use this lib to create pixel pirfect designs in web or react-native/native-script projects

version 1.0.0

Instalation

Installing from git:

npm i -S git+https://git@github.com/ingvardm/pixels2points.git#master

yarn add git+https://git@github.com/ingvardm/pixels2points.git#master

Installing from npm:

npm i -S pixels2points

yarn add pixels2points

Installing with bower:

Usage

Require and configure:

const pixels2points = require('pixels2points')

const calcSize = pixels2points.calculate

// configure device and design width in pixels
pixels2points.configure({
    deviceWidth: 640,
    designWidth: 750
})

console.log(calcSize(200)) // 170.66666666666666

Use built in roundeing function to round output to nearest integer;

pixels2points.configure({
    roundToNearestPoint: true
})

console.log('rounded ', calcSize(200)) // rounded 171

Configure pixels2points to use custom middlewear function:

const myRoundingFunction = function(points){
    return Math.floor(points)
}

pixels2points.configure({
    roundToNearestPoint: false,
    middlewear: myRoundingFunction
})

console.log('rounded down ', calcSize(200)) // rounded down 170

Run with parameters:

var buttonWidth = calcSize(200, {
    deviceWidth: 720,
    middlewear: points => points > 150 ? 120 : 100
})

console.log('responsive button width = ', buttonWidth)
// responsive button width =  120

use chached values for better performance:

pixels2points.configure({
    cache: true,
    middlewear: null // Dont forget to reset previously configured parameters
})

var buttonWidthA = calcSize(200)

console.log('200 isn\'cached, calculating...', buttonWidthA)
// 200 isn'cached, calculating... 170.66666666666666

var buttonWidthB = calcSize(200)

console.log('200 IS cached, returning chached value', buttonWidthB)
// 200 IS cached, returning chached value 170.66666666666666
