Detecting outside clicks in Vue.js

See this StackOverflow thread

First off, include the directive at the end of this gist.

1. On your open button, make sure to use @click.stop to prevent the open click event from closing your modal.
2. On your modal, add the v-click-outside directive and points it at a function to call when clicked outside.

Example:

/*
Usage: 

import getImageKitModifierQueryString from "getImageKitModifiers.js";

const IMAGEKIT_CDN_ROOT = "https://ik.imagekit.io/my-app/";
const myImageKey = "image.jpg";

const modifierQueryString = getImageKitModifierQueryString({

It includes line wrap, page wrap, and some styling control:

function convertPointsToUnit(points, unit) {
  // Unit table from https://github.com/MrRio/jsPDF/blob/ddbfc0f0250ca908f8061a72fa057116b7613e78/jspdf.js#L791
  var multiplier;
  switch(unit) {
    case 'pt':  multiplier = 1;          break;
    case 'mm':  multiplier = 72 / 25.4;  break;
    case 'cm':  multiplier = 72 / 2.54;  break;
    case 'in':  multiplier = 72;         break;
    case 'px':  multiplier = 96 / 72;    break;

Stripe Checkout: Multiple Checkout buttons on the same page

Suppose you have a Stripe Checkout page setup to sell a product.

To link to your payment page, you must generate a Checkout button HTML snippet for display on your site. However, the default snippet only supports one Checkout button. You cannot have several Checkout buttons for the same product on the same page.

This gist modifies Stripe's generated snippet to support several buttons.

Vue.js: Use Sentry.io without increasing initial bundle size

There's no questions about it: in the age of "fat" frontend clients, less bloat is better. A useful technique is to split off large libraries into separate Webpack chunks so the they don't take up space in your main bundle, delaying the initial load of your webapp. I like doing this with what I call the "installer pattern". Every split-out library gets its own "installer", an async function that loads the Webpack chunk, performs any initializations or configuration necessary, and then informs the relevant parts of your app that loading has completed.

Here's what that pattern looks like for installing the Sentry.io error reporting SDK:

First, add Sentry to your project:
