Question

What is the best location to store common utility functions that will be utilized by various Vue.js components?

Typically, I create functions within the component that will use them. However, I am finding that I need to use a particular function in multiple components now. Currently, I would have to duplicate and paste the function into each component, which is not ideal. I am unsure of where I should place these functions for better organization. Here's an example of a general utility function:

winrate(wins, losses) {
    let games = wins + losses
    return Math.round(wins * 100 / games) + '%'
}

It's a simple function that calculates the win rate based on wins and losses.

I am utilizing Vuex and I could potentially store them there, but I'm unsure if that is the most efficient solution. Any advice would be greatly appreciated!

Answer №1

It's a common approach to keep these kinds of functions (referred to as helpers) in files like helpers.js or utils.js. Here's an example of what the code might look like:

export function calculateWinRate(wins, losses) {
    let totalGames = wins + losses
    return Math.round(wins * 100 / totalGames) + '%'
}

Afterwards, you can simply import this helper function into your component:

import { calculateWinRate } from './path/to/helpers.js'

export default {
  // ...
  methods: {
    someMethod() {
      console.log(calculateWinRate(1, 2))
    }
  }
  // ...
}
