1 <!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
2 1) The <head> information in this page is significant, should be uniform
3 across api docs and should be edited only with knowledge of the
4 templating mechanism.
5 3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
6 browser, it will be re-generated from the template, json schema and
7 authored overview content.
8 4) The <body>.innerHTML is also generated by an offline step so that this
9 page may easily be indexed by search engines.

215 This page talks about packaged apps—how
216 you implement them,
217 and how they're different from
218 extensions and ordinary web apps.
219 </p>
220 <h2 id="overview">Overview</h2>
221 <p>
222 A packaged app is a web app
223 that's bundled into a <code>.crx</code> file
224 and can use Chrome extension features.
225 You build a packaged app just like you build an extension,
226 except that a packaged app can't include a
227 <a href="browserAction.html">browser action</a> or
228 <a href="pageAction.html">page action</a>.
229 Instead, a packaged app includes at least one HTML file
230 within its <code>.crx</code> file
231 that provides the app's user interface.
232 </p>
233 <p>
234 Packaged apps are a type of
235 <a href="http://code.google.com/chrome/apps/">installable web app</a>—a
236 web app that can be installed in Chrome.
237 The other type of installable web app is a
238 <a href="http://code.google.com/chrome/apps/docs/developers_guide.html">hosted a pp</a>,
239 which is an ordinary web app with a bit of additional metadata.
240 </p>
241 <p>
242 If you're developing a web app for the Chrome Web Store,
243 you might want to use a packaged app
244 instead of a hosted app if any of the following are true:
245 </p>
246 <ul>
247 <li>
248 You don't want to run a service to host your app.
249 </li>
250 <li>
251 You want to build an app that works really well offline.
252 </li>
253 <li>
254 You want tighter integration with Chrome,
255 using the extension APIs.
256 </li>
257 </ul>
258 <p>
259 To learn more about
260 the differences between web apps and websites,
261 extensions and packaged apps, and packaged apps and hosted apps,
262 read these:

268 </ul>
269 <h2 id="manifest"> The manifest </h2>
270 <p>
271 A packaged app's manifest can have any field
272 that's available to extensions,
273 except for "browser_action" and "page_action".
274 In addition, a packaged app's manifest <b>must</b>
275 have an "app" field.
276 Here is a typical manifest for a packaged app:
277 </p>
278 <pre>{
279 "name": "My Awesome Racing Game",
280 "description": "Enter a world where a Vanagon can beat a Maserati",
281 "version": "1",
282 <b>"app": {
283 "launch": {
284 "local_path": "main.html"
285 }
286 },</b>
287 "icons": {
288 "16": "icon_16.png",
289 "128": "icon_128.png"
290 }
291 }
292 </pre>
293 <p>
294 The "app" field has one subfield, "launch",
295 which specifies the <em>launch page</em> for the app—the
296 page (HTML file bundled into the <code>.crx</code> file)
297 that the browser goes to when the user clicks the app's icon
298 in the New Tab page.
299 The "launch" field can contain the following:
300 </p>
301 <dl>
302 <dt>local_path:</dt>
303 <dd><em>Required.</em>
304 Specifies the launch page
305 as a relative path referring to a file
306 in the <code>.crx</code> package.
307 </dd>
308 <dt>container:</dt>
309 <dd> The value "panel" makes the app appear
310 in an app panel.
311 By default, or when you specify "tab",
312 the app appears in a tab.
313 <!-- PENDING: In the overview
314 (or somewhere else before here)
315 we should show and define both app panels and tabs.
316 We should link to that place from here. -->
317 </dd>
318 <dt>height:</dt>
319 <dd>
320 If the container is set to "panel",
321 this integer specifies the height
322 of the panel in pixels.
323 For example, you might specify
324 <code>"height":400</code>.
325 Note that you don't use quotation marks in the value.
326 This field specifies the height of the area
327 to display contents in;
328 window decorations add a few more pixels to the total height.
329 If the container isn't a panel, this field is ignored.
330 </dd>
331 <dt>width:</dt>
332 <dd>
333 Similar to "height",
334 but specifies the width of the panel.
335 </dd>
336 </dl>
337 <p>
338 Packaged apps usually provide a 16x16 icon
339 to be used as the favicon for
340 tabs that contain app's pages.
341 They also should provide a 128x128 icon,
342 but not a 48x48 icon.
343 See the manifest documentation for the
344 <a href="manifest.html#icons">"icons" field</a>
345 for more information.
346 </p>
347 <p>
348 For further details on what a packaged app's manifest can contain, see the
349 <a href="manifest.html">manifest documentation</a>.
