Fuel Consumption Calculator Library

A simple Js Library that calculates the cost of the necessary fuel to go through a path.

How to use it

1. Clone this repo

2. Import the library into your project, you can use Js injection or ES6 import.

3. Instanciate a new FuelConsumptionCalculator() passing as a param an object that contains:

   • distance : the total distance of the travel
   • fuelPer100Km: the average consumption needed by a car to run across 100km
   • fuelCost: average cost of the fuel

4. Call computeConsumption() to have back an object that contains:

   • distance : the total distance of the travel
   • fuelAmount : the total fuel required by the travel
   • totalCost : the total cost required by the travel

Available methods

• computeConsumption() : a method that calculates the amount of distance, fuel and costs given a travel;
• addStage(): you can even add intermediate stage to the travel. This will increase the amount of distance and fuelAmount to calculate the totalCost

Working example

You can find a working example in the sample folder, just run npm i and suddenly npm start to start the example running in your browser.

Example with default distance

const fuelConsumption = new FuelConsumptionCalculator({
  distance: 10.1,
  fuelPer100Km: 6.2,
  fuelCost: 1.8,
})

// Return total costs
fuelConsumption.computeConsumption()

Example with intermediate stages

const fuelConsumption = new FuelConsumptionCalculator({
  fuelPer100Km: 6.2,
  fuelCost: 1.8,
})
// Adding an intermediate stage
fuelConsumption.addStage({ distance: 10 })
// Adding an intermediate stage
fuelConsumption.addStage({ distance: 3 })
// Adding an intermediate stage
fuelConsumption.addStage({ distance: 8.4 })
// Adding an intermediate stage
fuelConsumption.addStage({ distance: 2 })
// Return total costs
fuelConsumption.computeConsumption()
