You will need to build your project with something like [webpack](https://github.com/webpack/webpack) in order to use this._ You can also include this library in your HTML page directly from a CDN: ```html ``` _Note: you should use the latest version at the time that you include your project. You can see all versions [on the releases page](https://github.com/catdad/canvas-confetti/releases)._ ## Reduced Motion Thank you for joining me in this very important message about motion on your website. See, [not everyone likes it, and some actually prefer no motion](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion). They have [ways to tell us about it](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion) and we should listen. While I don't want to go as far as tell you not to have confetti on your page just yet, I do want to make it easy for you to respect what your users want. There is a `disableForReducedMotion` option you can use so that users that have trouble with chaotic animations don't need to struggle on your website. This is disabled by default, but I am considering changing that in a future major release. If you have strong feelings about this, [please let me know](https://github.com/catdad/canvas-confetti/issues/new). For now, please confetti responsibly. ## API When installed from `npm`, this library can be required as a client component in your project build. When using the CDN version, it is exposed as a `confetti` function on `window`. ### `confetti([options {Object}])` → `Promise|null` `confetti` takes a single optional object. When `window.Promise` is available, it will return a Promise to let you know when it is done. When promises are not available (like in IE), it will return `null`. You can polyfill promises using any of the popular polyfills. You can also provide a promise implementation to `confetti` through: ```javascript const MyPromise = require('some-promise-lib'); const confetti = require('canvas-confetti'); confetti.Promise = MyPromise; ``` If you call `confetti` multiple times before it is done, it will return the same promise every time. Internally, the same canvas element will be reused, continuing the existing animation with the new confetti added. The promise returned by each call to `confetti` will resolve once all animations are done. #### `options` The `confetti` parameter is a single optional `options` object, which has the following properties: - `particleCount` _Integer (default: 50)_: The number of confetti to launch. More is always fun... but be cool, there's a lot of math involved. - `angle` _Number (default: 90)_: The angle in which to launch the confetti, in degrees. 90 is straight up. - `spread` _Number (default: 45)_: How far off center the confetti can go, in degrees. 45 means the confetti will launch at the defined `angle` plus or minus 22.5 degrees. - `startVelocity` _Number (default: 45)_: How fast the confetti will start going, in pixels. - `decay` _Number (default: 0.9)_: How quickly the confetti will lose speed. Keep this number between 0 and 1, otherwise the confetti will gain speed. Better yet, just never change it. - `gravity` _Number (default: 1)_: How quickly the particles are pulled down. 1 is full gravity, 0.5 is half gravity, etc., but there are no limits. You can even make particles go up if you'd like. - `drift` _Number (default: 0)_: How much to the side the confetti will drift. The default is 0, meaning that they will fall straight down. Use a negative number for left and positive number for right. - `ticks` _Number (default: 200)_: How many times the confetti will move. This is abstract... but play with it if the confetti disappear too quickly for you. - `origin` _Object_: Where to start firing confetti from. Feel free to launch off-screen if you'd like. - `origin.x` _Number (default: 0.5)_: The `x` position on the page, with `0` being the left edge and `1` being the right edge. - `origin.y` _Number (default: 0.5)_: The `y` position on the page, with `0` being the top edge and `1` being the bottom edge. - `colors` _Array<String>_: An array of color strings, in the HEX format... you know, like `#bada55`. - `shapes` _Array<String>_: An array of shapes for the confetti. The possible values are `square` and `circle`. The default is to use both shapes in an even mix. You can even change the mix by providing a value such as `['circle', 'circle', 'square']` to use two third circles and one third squares. - `scalar` _Number (default: 1)_: Scale factor for each confetti particle. Use decimals to make the confetti smaller. Go on, try teeny tiny confetti, they are adorable! - `zIndex` _Integer (default: 100)_: The confetti should be on top, after all. But if you have a crazy high page, you can set it even higher. - `disableForReducedMotion` _Boolean (default: false)_: Disables confetti entirely for users that [prefer reduced motion](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion). The `confetti()` promise will resolve immediately in this case. ### `confetti.create(canvas, [globalOptions])` → `function` This method creates an instance of the `confetti` function that uses a custom canvas. This is useful if you want to limit the area on your page in which confetti appear. By default, this method will not modify the canvas in any way (other than drawing to it). _Canvas can be misunderstood a bit though, so let me explain why you might want to let the module modify the canvas just a bit. By default, a `canvas` is a relatively small image -- somewhere around 300x150, depending on the browser. When you resize it using CSS, this sets the display size of the canvas, but not the image being represented on that canvas. Think of it as loading a 300x150 jpeg image in an `img` tag and then setting the CSS for that tag to `1500x600` -- your image will end up stretched and blurry. In the case of a canvas, you need to also set the width and height of the canvas image itself. If you don't want to do that, you can allow `confetti` to set it for you._ Note also that you should persist the custom instance and avoid initializing an instance of confetti with the same canvas element more than once. The following global options are available: * `resize` _Boolean (default: false)_: Whether to allow setting the canvas image size, as well as keep it correctly sized if the window changes size (e.g. resizing the window, rotating a mobile device, etc.). By default, the canvas size will not be modified. * `useWorker` _Boolean (default: false)_: Whether to use an asynchronous web worker to render the confetti animation, whenever possible. This is turned off by default, meaning that the animation will always execute on the main thread. If turned on and the browser supports it, the animation will execute off of the main thread so that it is not blocking any other work your page needs to do. Using this option will also modify the canvas, but more on that directly below -- do read it. If it is not supported by the browser, this value will be ignored. * `disableForReducedMotion` _Boolean (default: false)_: Disables confetti entirely for users that [prefer reduced motion](https://developer.mozilla.org/en-US/docs/Web/CSS/@media/prefers-reduced-motion). When set to true, use of this confetti instance will always respect a user's request for reduced motion and disable confetti for them. _**Important: If you use `useWorker: true`, I own your canvas now. It's mine now and I can do whatever I want with it (don't worry... I'll just put confetti inside it, I promise). You must not try to use the canvas in any way (other than I guess removing it from the DOM), as it will throw an error. When using workers for rendering, control of the canvas must be transferred to the web worker, preventing any usage of that canvas on the main thread. If you must manipulate the canvas in any way, do not use this option.**_ ```javascript var myCanvas = document.createElement('canvas'); document.body.appendChild(myCanvas); var myConfetti = confetti.create(myCanvas, { resize: true, useWorker: true }); myConfetti({ particleCount: 100, spread: 160 // any other options from the global // confetti function }); ``` ### `confetti.reset()` Stops the animation and clears all confetti, as well as immediately resolves any outstanding promises. In the case of a separate confetti instance created with [`confetti.create`](#confetticreatecanvas-globaloptions--function), that instance will have its own `reset` method. ```javascript confetti(); setTimeout(() => { confetti.reset(); }, 100); ``` ```javascript var myCanvas = document.createElement('canvas'); document.body.appendChild(myCanvas); var myConfetti = confetti.create(myCanvas, { resize: true }); myConfetti(); setTimeout(() => { myConfetti.reset(); }, 100); ``` ## Examples Launch some confetti the default way: ```javascript confetti(); ``` Launch a bunch of confetti: ```javascript confetti({ particleCount: 150 }); ``` Launch some confetti really wide: ```javascript confetti({ spread: 180 }); ``` Get creative. Launch a small poof of confetti from a random part of the page: ```javascript confetti({ particleCount: 100, startVelocity: 30, spread: 360, origin: { x: Math.random(), // since they fall down, start a bit higher than random y: Math.random() - 0.2 } }); ``` I said creative... we can do better. Since it doesn't matter how many times we call `confetti` (just the total number of confetti in the air), we can do some fun things, like continuously launch more and more confetti for 30 seconds, from multiple directions: ```javascript // do this for 30 seconds var duration = 30 * 1000; var end = Date.now() + duration; (function frame() { // launch a few confetti from the left edge confetti({ particleCount: 7, angle: 60, spread: 55, origin: { x: 0 } }); // and launch a few from the right edge confetti({ particleCount: 7, angle: 120, spread: 55, origin: { x: 1 } }); // keep going until we are out of time if (Date.now() < end) { requestAnimationFrame(frame); } }()); ``` canvas-confetti-1.5.1/bin/000077500000000000000000000000001420056571600153605ustar00rootroot00000000000000canvas-confetti-1.5.1/bin/on_failure.sh000077500000000000000000000007711420056571600200470ustar00rootroot00000000000000green=`tput setaf 2` reset=`tput sgr0` line_break () { echo -------------------------------------- } print_green () { echo "${green}$@${reset}" } upload_file () { filename=$1 urlname=${filename// /_} downloadurl=`curl -sS --upload-file "./$filename" https://transfer.sh/$urlname` echo image \"$filename\" print_green " uploaded to: $downloadurl" } find_files () { cd shots echo list of files present: ls -l line_break for i in *.png;do upload_file "$i";done } find_files canvas-confetti-1.5.1/build/000077500000000000000000000000001420056571600157075ustar00rootroot00000000000000canvas-confetti-1.5.1/build/.eslintrc.yml000066400000000000000000000001351420056571600203320ustar00rootroot00000000000000env: es6: true node: true browser: false parser: babel-eslint rules: no-console: off canvas-confetti-1.5.1/build/build.js000066400000000000000000000024611420056571600173470ustar00rootroot00000000000000const fs = require('fs'); const { promisify } = require('util'); const { name, version, main } = require('../package.json'); const buildDate = (new Date()).toISOString(); function mkdir(dir) { return promisify(fs.mkdir)(dir).then(() => { return Promise.resolve(); }).catch(err => { if (err.code === 'EEXIST') { return Promise.resolve(); } return Promise.reject(err); }); } function readFile(file, encoding) { return promisify(fs.readFile)(file, encoding); } function writeFile(file, content) { return promisify(fs.writeFile)(file, content); } function buildCommonJs(content) { return `// ${name} v${version} built on ${buildDate} !(function (window, module) { // source content ${content} // end source content window.confetti = module.exports; }(window, {})); `; } function buildModule(content) { return `// ${name} v${version} built on ${buildDate} var module = {}; // source content ${content} // end source content export default module.exports; export var create = module.exports.create; `; } mkdir('dist') .then(() => readFile(main)) .then(file => { return Promise.all([ writeFile('dist/confetti.browser.js', buildCommonJs(file)), writeFile('dist/confetti.module.mjs', buildModule(file)) ]); }) .catch(err => { console.error(err); process.exitCode = 1; }); canvas-confetti-1.5.1/build/serve.js000066400000000000000000000033771420056571600174030ustar00rootroot00000000000000const path = require('path'); const http = require('http'); const send = require('send'); const root = require('rootrequire'); const PORT = 9001; http.createServer(function (req, res) { const url = req.url === '/' ?

Canvas Confetti

Basic Cannon

The default mode... just your regular basic average blast of confetti. But it's still a little cool, right?

Random Direction

Go crazy with some randomness. Shoot a random amount of confetti in random directions. (Go ahead... you know you want to click that button more than once.)

Realistic Look

If you happened to get curious and changed the particle count to 400 or so, you saw something disappointing. An even "flattened cone" look to the confetti, making it look way too perfect and ruining the illusion. We can fix that by mixing a few effects together.

Fireworks

Why click a button repeatedly when you can have code do it for you? Shoot some firework of confetti from the sides of page so you can still read the content in the center.

Snow

The effect is not limited to crazy rapid fire of confetti though. You can create a wintery mood with gently falling particles across the entire page.

School Pride

But if you are into crazy rapid fire of confetti, what could be a better use than to show everyone what you are all about? Tell people where you are from with two confetti cannons from either side of the page.

🌰 Go Buckeyes! 🌰

Custom Canvas

But if you just hate confetti all over the place, there's something here for you as well. You can limit where the confetti appear by providing your own canvas element.
