We'd like this to be a project that anyone feels welcome and empowered to be a part of, whether that's contributing documentation, writing code, teaching with it, or using it to create. We are also putting a lot of energy into making the documentation clear, for developers as well as users. We have begun working with various schools and institutions to teach workshops and classes, in hopes of integrating it into curricula as a tool for understanding the web. Most importantly, this project is in active development, with enthusiastic support and contributions from around the world. There is also an option to use p5 globally or instantiated within a namespace, so it can be compatible with other JS libraries. p5.js will also have a system for people to contribute add-on modules to deal with things like audio, video, various input devices, and data. Through this framework beginners begin to explore and understand HTML, JavaScript, and CSS, and the way they work together in the browser. We are closely studying the decisions Processing has made, but also always questioning to see if there are design decisions that would make the library cleaner, stronger, and more intuitive.Īdditionally, p5.js extends beyond canvas drawing to allow people to create, access and manipulate other HTML elements. From there, they are able to begin writing native JS using a syntax that feels familiar but appropriate for the context. It is easy to translate a sketch from Processing to p5 and the process of doing so begins to teach people the basics of JS. In contrast, with p5 we are reimagining Processing's original goals in native JavaScript, in a way that is intended to be transparent and intuitive. As Processing.js says on their website, "it's not magic, but almost." It can be difficult for someone to understand how it works, how to fix things when it doesn't work, or how to modify or extend the library. It is a good tool for those that want to run simple sketches on the web, however, it is quite opaque. Processing.js is a port of Processing to JS, using regex to convert Java into JS. It supports a mixed syntax of Processing and JavaScript, where the JavaScript is not really meant to be consumed by the end-user. The main goal of Processing.js is to execute Processing files in HTML5, but not necessarily to write native HTML5. FAQ How is this different than Processing.js? Here are the instructions for setting up a local server. You can usually run p5.js sketches without a server, but it is required if you are doing certain things like loading external files. The p5.js web editor handles setting up projects and the server is set up internally for you. You can use any editing environment you like, in addition, the p5.js web editor has been officially launched, you can try that out too. Learn how to use these libraries or develop your own here. There is also a p5.sound library that provides a friendly interface to HTML5 web audio API for loading, playing, and synthesizing sounds. For this reason, there is the p5.dom library that makes it easy to interact with other HTML5 objects, including text, hyperlink, image, input, video, audio, and webcam. One of the core ideas behind p5.js is that your sketch is not just the graphics canvas but the whole web page in your browser. The draw() block runs repeatedly, and is used for animation.įor your first "Hello World" program, create a setup() block and add one line:įunction setup ( ) Libraries The setup() block runs once, and is typically used for initialization, or for creating a program that does not need a loop running code repeatedly. There are two main functions you will use in your program. Please see the get started page for instructions for setting up your editing environment and project. You can also read how this differs from processing.js, or about how this relates to Processing. P5.js is a new interpretation, not an emulation or port, and it is in active development. However, you're not limited to your drawing canvas, you can think of your whole browser page as your sketch! For this, p5.js has addon libraries that make it easy to interact with other HTML5 objects, including text, input, video, webcam, and sound. Using the original metaphor of a software sketchbook, p5.js has a full set of drawing functionality. P5.js is a JavaScript library that starts with the original goal of Processing-to make coding accessible for artists, designers, educators, and beginners-and reinterprets this for today's web.
