================================================
The following examples are all stand-alone apps, such as servers, that run
from the command line. Most of the examples use the `dart:io` library, which is
used solely for command-line applications running on a stand-alone Dart VM.
<strong>The `dart:io` library does not work in browser-based
applications</strong>.
Many examples also use Pub packages.
<aside class="alert alert-info" markdown="1">
**Note:**
Many server-side APIs provide both asynchronous and synchronous ways to
accomplish a task. For example, to read a file as a string you can use either
the asynchronous `readAsString()` method from the File class, or its synchronous
counterpart, `readAsStringSync()`.
<strong>The examples below use only the asynchronous versions.</strong>
</aside>
See the
[source on Github](https://github.com/dart-lang/dart-samples/tree/master/dart_io_mini_samples).
After looking at the following code examples, refer to
[Write Command-line Apps](/tutorials/dart-vm/cmdline)
for additional information about I/O and command-line apps.

This directory includes deferred loading examples for the Dart language.
[deferred_loading_example](deferred_loading_example/README.md)
: A tiny command-line example that loads a single deferred library on startup.
[lazyloader](lazyloader/README.md)
: A browser-based example that loads one of three libraries when the
user clicks the corresponding button.
For more information, see
[Dart Deferred Loading](https://www.dartlang.org/docs/spec/deferred-loading.html).
================================================
FILE: deferred_loading_samples/deferred_loading_example/README.md
================================================
This project demonstrates the simplest example of deferred loading.
The lib/hello.dart file is loaded lazily, on startup.
Once loaded, the library prints a Hello World style greeting.
You can run this from the command line, using
`pub run bin/main', for example.

## Dart HTML5 Samples
Most of them were ported from [HTML5 Rocks](http://www.html5rocks.com/).
So far, the samples cover HTML5 topics. We want to expand the scope of the
samples to cover other topics as well.
* [Using Application Cache](web/appcache/beginner)
* [High DPI Canvas](web/canvas/hidpi)
* [Using Image Filters with Canvas](web/canvas/imagefilters)
* [Basic Drag and Drop](web/dnd/basics)
* [Using the File APIs](web/file/dndfiles)
* [Exploring the FileSystem APIs](web/file/filesystem)
* [A Terminal Emulator that uses the FileSystem APIs](web/file/terminal)
* [Trip Meter: A Basic Geolocation Example](web/geolocation/trip_meter)
* [Simple Todo App using IndexedDB](web/indexeddb/todo)
* [LocalStorage 101](web/localstorage/basics)
* [Pointer Lock And First Person Shooter Controls](web/pointerlock/fps)

## Using Application Cache
A simple example to show the use of the Application Cache interface.
For a thorough exploration of this topic, read
[A Beginner's Guide to Using the Application
Cache](http://www.html5rocks.com/en/tutorials/appcache/beginner/),
an article by Eric Bidelman originally published on HTML5Rocks.
Application Cache allows you to specify which files the browser should cache
and make available to offline users. Your app will
load and work correctly, even if the user presses the refresh button while
offline.
To see this example in action, make changes to `index.html` and then reload
the app. Your changes don't show up because the browser displays a cached
version of `index.html`. Next, change the date or version number in
appcache.mf, and reload once more. You'll be prompted to load the new version.
Please report any [bugs or feature requests](http://dartbug.com/new).

## Using Image Filters with Canvas
A port of the examples used in the
[Image Filters with Canvas](http://www.html5rocks.com/en/tutorials/canvas/imagefilters/)
article by Ilmari Heikkinen, originally published on HTML5Rocks.
The article describes how to use image filters with an HTML5 Canvas element.
It explains how to process pixels, run simple filters, and blur,
sharpen and emboss an image using convolution filters.
Please report any [bugs or feature requests](http://dartbug.com/new).

## Basic Drag and Drop
A port of the Drag and Drop example used in the
[Native HTML5 Drag and Drop](http://www.html5rocks.com/en/tutorials/dnd/basics/)

HTML5 Drag and drop (DnD) is event-based way of making an element draggable
on a page. Native browser support for this feature means faster, more responsive
web apps.

## Using the File APIs
A Dart port of the Files API examples used in the
[Reading files in JavaScript using the File APIs](http://www.html5rocks.com/en/tutorials/file/dndfiles/)
article by Eric Bidelman, originally published on HTML5Rocks.
The examples show how to select a file using a form input, or using drag and
drop. See how you can slice a file in separate byte range
chunks for efficient uploading, and monitor progress while uploading a file.

## A Terminal Emulator that uses the FileSystem APIs
A port of the Terminal example used in the
[Exploring the FileSystem APIs](http://www.html5rocks.com/en/tutorials/file/filesystem/)
article by Eric Bidelman, originally published on HTML5Rocks.
With the FileSystem API, a web app can create, read, navigate, and write to a
sandboxed section of the user's local file system.
This example simulates a UNIX terminal, and replicates common UNIX filesystem
operations such as `cd`, `mkdir`, `rm`, `open`, and `cat` using the FileSystem
API. To add content, open the app, then drag and drop files from your
desktop onto the terminal window.
Please report any [bugs or feature requests](http://dartbug.com/new).

## Trip Meter: A Basic Geolocaton Example
A port of the Geolocation example used in the
[A Simple Trip Meter Using the Geolocation API] (http://www.html5rocks.com/en/tutorials/geolocation/trip_meter/)
article by Michael Mahemoff, originally published on HTML5Rocks.
The Geolocation API lets you track a user's location. The API is
device-agnostic; the underlying mechanism might be via GPS,
wifi, or simply asking the user to enter their location manually. Since
these lookups can take some time, the API is asynchronous, and you
pass it a callback method whenever you request a location.
The Trip Meter example display's the user's initial location, and it
tracks the distance the user has travelled since the page was loaded.
Please report any [bugs or feature requests](http://dartbug.com/new).

## Simple Todo App using IndexedDB
A port of the Todo example used in the
[A Simple TODO list using HTML5 IndexedDB](http://www.html5rocks.com/en/tutorials/file/filesystem/)
article by Paul Kinlan, originally published on HTML5Rocks.
The example demonstrates how to create a very simple todo
list manager using IndexedDB.
IndexedDB is a data store that developers can use to store and manipulate data
on the client side. IndexedDB is usually used as an Asynchronous API where the
data is delivered to a defined callback function.
You can open the example in Dart Editor and run it by clicking `index.html`.
Or, you can try this
[live demo](http://www.html5rocks.com/en/tutorials/indexeddb/todo/).
Please report any [bugs or feature requests](http://dartbug.com/new).

## LocalStorage 101
A basic example showing the use of LocalStorage for persistence.
LocalStorage is a simple key/value storage interface for Strings.
Though widely supported, LocalStorage is a synchronous API. Because it involves
I/O, this interface should not be used for high throughput operations.
Consider IndexedDB as an alternative. For simple string keys and values, and as
a replacement for cookies, LocalStorage is useful.
When you enter a value in the username input in the example,
it is stored in LocalStorage.
The value is then retrieved from LocalStorage and displayed on the page.
Please report any [bugs or feature requests](http://dartbug.com/new).

## Working with RequestAnimationFrame
A port of the example used in the
[Leaner, Meaner, Faster Animations with requestAnimationFrame](http://www.html5rocks.com/en/tutorials/speed/animations/)
article by Paul Lewis, originally published on HTML5Rocks.
The article explains how to correctly use requestAnimationFrame for your
animations. Here is a summary of the article contents:
* Decouple your events from animations
* Avoid animations that result in reflow-repaint loops
* Update your RAF calls to expect a high resolution timestamp as the first
parameter
* Only call RAF when you have visual updates to do
Use the up and down keys to activate the animation. The up key moves the
circles from right to left, and the down key moves them from left to right.
Please report any [bugs or feature requests](http://dartbug.com/new).
