Flowsnake

Flowsnake is an Open Source library used by the Flowsnake mobile application. It's a ES6 library so it can also be used with NodeJS, React Native and on modern browsers.

Flowsnake is possible thanks to:

• Decimal.js
• Jest
• Babel
• Many more...

Install & usage

npm install -s flowsnake

For example to convert from Celsius to Kelvin use:

import Flowsnake from 'flowsnake'; // ES6
const Flowsnake = require('flowsnake'); // NodeJS

const res = Flowsnake.convert(1).from('°C').to('K');
res.eq(274.15) // true!

Features

Unit Conversion

Flowsnake includes many many many unit conversions. Check the units README for a complete list.

Example

For example to convert from Celsius to Kelvin use:

const res = Flowsnake.convert(1).from('°C').to('K');
res.eq(274.15) // true!

Calculators

Flowsnake includes some easy to use calculators:

• Download time calculator.
• Tip calculator.
• Prime factorization.
• Divisors.
• Body Mass Index (BMI).
• Body Fat Percentage (BFP).
• Ohm's Law.
• Electricity Cost.
• Loan Calculator.
• Resistor color code calculator (from colors to resistance [Ω] and viceversa).
• Inductor color code calculator (from colors to inductance [µH] and viceversa).

Algebra

• Combinations & permutations
• Greatest Common Denominator & Lowest Common Multiplier
• Fraction Simplifier
• Proportions

Example

// Calculate Download Time
const values = {
    size: Flowsnake.unit(28).as('GB'),
    speed: Flowsnake.unit(300).as('Mbps')
};
const seconds = Flowsnake.calculate('download-time').of(values);
const minutes = Flowsnake.convert(seconds).to('min');
minutes.equals(12.4445); // true!

// Prime factors
Flowsnake.calculate('prime-factors').of(147); // '3×7²'

Geometry

• Triangle
• Square
• Rectangle
• Rhombus
• Parallelogram
• Circle

Check the Geometry README for more information.

Example

// Solve a circle
const s = Circle.of({radius: 50});

s.diameter -> 100
s.area -> 7853.98
s.circumference -> 314.16
