| 436 | A basic ray-caster | Advanced, Canvas, Example, Graphics, HTML, Web |
| 437 | Canvas tutorial | Canvas, Graphics, Guide, HTML, HTML5, Intermediate, Web |
This tutorial describes how to use the <canvas> element to draw 2D graphics, starting with the basics. The examples provided should give you some clear ideas what you can do with canvas, and will provide code snippets that may get you started in building your own content. |
||
| 438 | Advanced animations | Canvas, Graphics, Tutorial |
| We are going to use a ball for our animation studies, so let's first draw that ball onto the canvas. The following code will set us up. | ||
| 439 | Applying styles and colors | Canvas, Graphics, HTML, HTML5, Intermediate, Tutorial |
Up until now we have only seen methods of the drawing context. If we want to apply colors to a shape, there are two important properties we can use: fillStyle and strokeStyle. |
||
| 440 | Basic animations | Canvas, Graphics, HTML, HTML5, Intermediate, Tutorial |
| Probably the biggest limitation is, that once a shape gets drawn, it stays that way. If we need to move it we have to redraw it and everything that was drawn before it. It takes a lot of time to redraw complex frames and the performance depends highly on the speed of the computer it's running on. | ||
| 441 | Basic usage of canvas | Canvas, Graphics, HTML, Intermediate, Tutorial |
At first sight a <canvas> looks like the <img> element, with the only clear difference being that it doesn't have the src and alt attributes. Indeed, the <canvas> element has only two attributes, width and height. These are both optional and can also be set using DOM properties. When no width and height attributes are specified, the canvas will initially be 300 pixels wide and 150 pixels high. The element can be sized arbitrarily by CSS, but during rendering the image is scaled to fit its layout size: if the CSS sizing doesn't respect the ratio of the initial canvas, it will appear distorted. |
||
| 442 | Compositing and clipping | Canvas, Graphics, HTML, HTML5, Intermediate, Tutorial |
We can not only draw new shapes behind existing shapes but we can also use it to mask off certain areas, clear sections from the canvas (not limited to rectangles like the clearRect() method does) and more. |

| This sample program demonstrates a number of compositing operations. The output looks like this: | ||
| 444 | Drawing shapes with canvas | Canvas, Graphics, HTML, HTML Canvas, HTML5, Intermediate, Tutorial |
 Before we can start drawing, we need to talk about the canvas grid or coordinate space. Our HTML skeleton from the previous page had a canvas element 150 pixels wide and 150 pixels high. To the right, you see this canvas with the default grid overlayed. Normally 1 unit in the grid corresponds to 1 pixel on the canvas. The origin of this grid is positioned in the top left corner at coordinate (0,0). All elements are placed relative to this origin. So the position of the top left corner of the blue square becomes x pixels from the left and y pixels from the top, at coordinate (x,y). Later in this tutorial we'll see how we can translate the origin to a different position, rotate the grid and even scale it, but for now we'll stick to the default. |

The content inside the <canvas> ... </canvas> tags can be used as a fallback for browsers which don't support canvas rendering. It's also very useful for assistive technology users (like screen readers) which can read and interpret the sub DOM in it. A good example at html5accessibility.com demonstrates how this can be done: |

||
| 1115 | Fetch basic concepts | API, Fetch, Fetch API, XMLHttpRequest, concepts, guard, request |
At the heart of Fetch are the Interface abstractions of HTTP Requests, Responses, Headers, and Body payloads, along with a global fetch method for initiating asynchronous resource requests.

| The File and Directory Entries API simulates a local file system that web apps can navigate within and access files in. You can develop apps which read, write, and create files and/or directories in a virtual, sandboxed file system. | ||
| 1143 | File and Directory Entries API support in Firefox | API, Chrome, Compatibility, File System API, File and Directory Entries API, Files, Firefox, Guide, Offline, Web Compatibility, google, google chrome |
| The original File System API was created to let browsers implement support for accessing a sandboxed virtual file system on the user's storage device. Work to standardize the specification was abandoned back in 2012, but by that point, Google Chrome included its own implementation of the API. Over time, a number of popular sites and Web applications came to use it, often without providing any means of falling back to standard APIs or even checking to be sure the API is available before using it. Mozilla instead opted to implement other APIs which can be used to solve many of the same problems, such as IndexedDB; see the blog post Why no FileSystem API in Firefox? for more insights. | ||

Also inherits methods from its parents IDBRequest and EventTarget. |
||
| 1770 | IDBOpenDBRequest.onblocked | API, Database, IDBOpenDBRequest, IndexedDB, Property, Reference, Storage, onblocked |
The onblocked event handler of the IDBOpenDBRequest interface is the event handler for the blocked event. This event is triggered when the upgradeneeded should be triggered because of a version change but the database is still in use (that is, not closed) somewhere, even after the versionchange event was sent. |
||
| 1771 | IDBOpenDBRequest.onupgradeneeded | API, Database, IDBOpenDBRequest, IndexedDB, Property, Reference, Storage, onupgradeneeded |

||
| 1773 | IDBRequest.error | API, Database, Error, IDBRequest, IndexedDB, Property, Reference, Storage |
A DOMError containing the relevant error. In Chrome 48+/Firefox 58+ this property returns a DOMException because DOMError has been removed from the DOM standard. The following error codes are returned under certain conditions: |
||
| 1774 | IDBRequest.onerror | API, Database, IDBRequest, IndexedDB, Property, Reference, Storage, onerror |
The following example requests a given record title, onsuccess gets the associated record from the IDBObjectStore (made available as objectStoreTitleRequest.result), updates one property of the record, and then puts the updated record back into the object store.

An IDBTransaction. |
||
| 1780 | IDBTransaction | API, Database, IDBTransaction, IndexedDB, Interface, MakeBrowserAgnostic, Reference, Storage |
Note that as of Firefox 40, IndexedDB transactions have relaxed durability guarantees to increase performance (see bug 1112702.) Previously in a readwrite transaction IDBTransaction.oncomplete was fired only when all data was guaranteed to have been flushed to disk. In Firefox 40+ the complete event is fired after the OS has been told to write the data but potentially before that data has actually been flushed to disk. The complete event may thus be delivered quicker than before, however, there exists a small chance that the entire transaction will be lost if the OS crashes or there is a loss of system power before the data is flushed to disk. Since such catastrophic events are rare most consumers should not need to concern themselves further. |

| 1822 | IndexedDB API | API, Advanced, Database, IndexedDB, Landing, Reference, Storage, jsstore |
| IndexedDB is a low-level API for client-side storage of significant amounts of structured data, including files/blobs. This API uses indexes to enable high-performance searches of this data. While Web Storage is useful for storing smaller amounts of data, it is less useful for storing larger amounts of structured data. IndexedDB provides a solution. This is the main landing page for MDN's IndexedDB coverage — here we provide links to the full API reference and usage guides, browser support details, and some explanation of key concepts. | ||

With server-sent events, it's possible for a server to send new data to a web page at any time, by pushing messages to the web page. These incoming messages can be treated as Events + data inside the web page. | ||

||
| 3425 | Service Worker API | API, Landing, Offline, Overview, Reference, Service Workers, Workers |
| Service workers essentially act as proxy servers that sit between web applications, the browser, and the network (when available). They are intended, among other things, to enable the creation of effective offline experiences, intercept network requests and take appropriate action based on whether the network is available, and update assets residing on the server. They will also allow access to push notifications and background sync APIs. | ||
| 3426 | Using Service Workers | Guide, Service, ServiceWorker, Workers, basics |
| One overriding problem that web users have suffered with for years is loss of connectivity. The best web app in the world will provide a terrible user experience if you can’t download it. There have been various attempts to create technologies to solve this problem, as our Offline page shows, and some of the issues have been solved. But the overriding problem is that there still isn’t a good overall control mechanism for asset caching and custom network requests. The previous attempt — AppCache — seemed to be a good idea because it allowed you to specify assets to cache really easily. However, it made many assumptions about what you were trying to do and then broke horribly when your app didn’t follow those assumptions exactly. Read Jake Archibald's Application Cache is a Douchebag for more details. |

| 3709 | Writing WebSocket servers | Guide, HTML5, NeedsContent, NeedsExample, Tutorial, WebSocket, WebSockets |
| A WebSocket server is a TCP application listening on any port of a server that follows a specific protocol, simple as that. The task of creating a custom server tends to scare people; however, it can be easy to implement a simple WebSocket server on your platform of choice. | ||
| 3710 | Writing a WebSocket server in C# | HTML5, NeedsMarkupWork, Tutorial, WebSockets |
| If you would like to use the WebSocket API, it is useful if you have a server. In this article I will show you how to write one in C#. You can do it in any server-side language, but to keep things simple and more understandable, I chose Microsoft's language. | ||

| 3732 | Touch events | Advanced, DOM, Event, Guide, Mobile, Overview, touch |
| In order to provide quality support for touch-based user interfaces, touch events offer the ability to interpret finger (or stylus) activity on touch screens or trackpads. | ||
| 3733 | Multi-touch interaction | Guide, TouchEvent, touch |
The touch event interfaces support application-specific single and multi-touch interactions. However, the interfaces can be a bit tricky for programmers to use because touch events are very different from other DOM input events, such as mouse events. The application described in this guide shows how to use touch events for simple single and multi-touch interactions, the basics needed to build application-specific gestures. |
||
| 3734 | Supporting both TouchEvent and MouseEvent | Guide, TouchEvent, touch |
The touch interfaces enable applications to create enhanced user experiences on touch enabled devices. However, the reality is the vast majority of today's web content is designed only to work with mouse input. Consequently, even if a browser supports touch, the browser must still emulate mouse events so content that assumes mouse-only input will work as is without direct modification. |
||
| 3735 | Using Touch Events | Guide, TouchEvent, touch |
Today, most Web content is designed for keyboard and mouse input. However, devices with touch screens (especially portable devices) are mainstream and Web applications can either directly process touch-based input by using Touch Events or the application can use interpreted mouse events for the application input. A disadvantage to using mouse events is that they do not support concurrent user input, whereas touch events support multiple simultaneous inputs (possibly at different locations on the touch surface), thus enhancing user experiences. |
||
| 3736 | TouchEvent | API, DOM, Interface, Reference, touch |

| 4025 | Porting webkitAudioContext code to standards based AudioContext | API, Reference, Référence(2), Web Audio API, porting, webkitAudioContext |
| The Web Audio standard was first implemented in WebKit, and the implementation was built in parallel with the work on the specification of the API. As the specification evolved and changes were made to the spec, some of the old implementation pieces were not removed from the WebKit (and Blink) implementations due to backwards compatibility reasons. New engines implementing the Web Audio spec (such as Gecko) will only implement the official, final version of the specification, which means that code using webkitAudioContext or old naming conventions in the Web Audio specification may not immediately work out of the box in a compliant Web Audio implementation. This article attempts to summarize the areas where developers are likely to encounter these problems and provide examples on how to port such code to standards based AudioContext, which will work across different browser engines. | ||

| Once you've successfully created a WebGL context, you can start rendering into it. A simple thing we can do is draw a simple square untextured plane, so let's start there, by building code to draw a square plane. | ||
| 4146 | Animating objects with WebGL | Tutorial, WebGL |

||
| 4148 | Creating 3D objects using WebGL | Tutorial, WebGL |
Let's take our square plane into three dimensions by adding five more faces to create a cube. To do this efficiently, we're going to switch from drawing using the vertices directly by calling the gl.drawArrays() method to using the vertex array as a table, and referencing individual vertices in that table to define the positions of each face's vertices, by calling gl.drawElements(). |
||
| 4149 | Getting started with WebGL | Tutorial, WebGL |
WebGL enables web content to use an API based on OpenGL ES 2.0 to perform 2D and 3D rendering in an HTML canvas in browsers that support it without the use of plug-ins. WebGL programs consist of control code written in JavaScript and shader code (GLSL) that is executed on a computer's Graphics Processing Unit (GPU). WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background. |

| 4150 | Lighting in WebGL | 3D, Fragments, Graphics, Guide, Light Sources, Shaders, Shading, Tutorial, Vertexes, WebGL, lighting, vertices |
| As should be clear by now, WebGL doesn't have much built-in knowledge. It just runs two functions you supply — a vertex shader and a fragment shader — and expects you to write creative functions to get the results you want. In other words, if you want lighting you have to calculate it yourself. Fortunately, it's not all that hard to do, and this article will cover some of the basics. | ||
| 4151 | Using shaders to apply color in WebGL | Tutorial, WebGL |
| Having created a square plane in the previous demonstration, the next obvious step is to add a splash of color to it. We can do this by revising the shaders. | ||
| 4152 | Using textures in WebGL | Tutorial, WebGL |

| 4621 | XSL Transformations in Mozilla FAQ | Guide, XSLT |
Make sure the mime type for both source and stylesheet are set to an XML mimetype, namely text/xml or application/xml. The XSLT namespace is http://www.w3.org/1999/XSL/Transform. Use the <?xml-stylesheet ?> processing instruction instead of the non-standard xml:stylesheet. The most common cause is the MIME type handling. To find out which MIME type your server sends, look at Page Info, use extensions like LiveHTTPHeaders or a download manager like wget. Mozilla won't load XSLT stylesheets from a different domain for security reasons. |
