# auto-updater
|
|
|
|
**This module has only been implemented for OS X.**
|
|
|
|
Check out [atom/grunt-atom-shell-installer](https://github.com/atom/grunt-atom-shell-installer)
|
|
for building a Windows installer for your app.
|
|
|
|
The `auto-updater` module is a simple wrap around the
|
|
[Squirrel.Mac](https://github.com/Squirrel/Squirrel.Mac) framework.
|
|
|
|
Squirrel.Mac requires that your `.app` folder is signed using the
|
|
[codesign](https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/codesign.1.html)
|
|
utility for updates to be installed.
|
|
|
|
## Squirrel
|
|
|
|
Squirrel is an OS X framework focused on making application updates **as safe
|
|
and transparent as updates to a website**.
|
|
|
|
Instead of publishing a feed of versions from which your app must select,
|
|
Squirrel updates to the version your server tells it to. This allows you to
|
|
intelligently update your clients based on the request you give to Squirrel.
|
|
|
|
Your request can include authentication details, custom headers or a request
|
|
body so that your server has the context it needs in order to supply the most
|
|
suitable update.
|
|
|
|
The update JSON Squirrel requests should be dynamically generated based on
|
|
criteria in the request, and whether an update is required. Squirrel relies
|
|
on server side support for determining whether an update is required, see
|
|
[Server Support](#server-support).
|
|
|
|
Squirrel's installer is also designed to be fault tolerant, and ensure that any
|
|
updates installed are valid.
|
|
|
|
## Update Requests
|
|
|
|
Squirrel is indifferent to the request the client application provides for
|
|
update checking. `Accept: application/json` is added to the request headers
|
|
because Squirrel is responsible for parsing the response.
|
|
|
|
For the requirements imposed on the responses and the body format of an update
|
|
response see [Server Support](#server-support).
|
|
|
|
Your update request must *at least* include a version identifier so that the
|
|
server can determine whether an update for this specific version is required. It
|
|
may also include other identifying criteria such as operating system version or
|
|
username, to allow the server to deliver as fine grained an update as you
|
|
would like.
|
|
|
|
How you include the version identifier or other criteria is specific to the
|
|
server that you are requesting updates from. A common approach is to use query
|
|
parameters, like this:
|
|
|
|
```javascript
|
|
// On the main process
|
|
var app = require('app');
|
|
var autoUpdater = require('auto-updater');
|
|
autoUpdater.setFeedUrl('http://mycompany.com/myapp/latest?version=' + app.getVersion());
|
|
```
|
|
|
|
## Server Support
|
|
|
|
Your server should determine whether an update is required based on the
|
|
[Update Request](#update-requests) your client issues.
|
|
|
|
If an update is required your server should respond with a status code of
|
|
[200 OK](http://tools.ietf.org/html/rfc2616#section-10.2.1) and include the
|
|
[update JSON](#update-json-format) in the body. Squirrel **will** download and
|
|
install this update, even if the version of the update is the same as the
|
|
currently running version. To save redundantly downloading the same version
|
|
multiple times your server must not inform the client to update.
|
|
|
|
If no update is required your server must respond with a status code of
|
|
[204 No Content](http://tools.ietf.org/html/rfc2616#section-10.2.5). Squirrel
|
|
will check for an update again at the interval you specify.
|
|
|
|
## Update JSON Format
|
|
|
|
When an update is available, Squirrel expects the following schema in response
|
|
to the update request provided:
|
|
|
|
```json
|
|
{
|
|
"url": "http://mycompany.com/myapp/releases/myrelease",
|
|
"name": "My Release Name",
|
|
"notes": "Theses are some release notes innit",
|
|
"pub_date": "2013-09-18T12:29:53+01:00",
|
|
}
|
|
```
|
|
|
|
The only required key is "url", the others are optional.
|
|
|
|
Squirrel will request "url" with `Accept: application/zip` and only supports
|
|
installing ZIP updates. If future update formats are supported their MIME type
|
|
will be added to the `Accept` header so that your server can return the
|
|
appropriate format.
|
|
|
|
`pub_date` if present must be formatted according to ISO 8601.
|
|
|
|
## Event: checking-for-update
|
|
|
|
Emitted when checking for update has started.
|
|
|
|
## Event: update-available
|
|
|
|
Emitted when there is an available update, the update would be downloaded
|
|
automatically.
|
|
|
|
## Event: update-not-available
|
|
|
|
Emitted when there is no available update.
|
|
|
|
## Event: update-downloaded
|
|
|
|
* `event` Event
|
|
* `releaseNotes` String
|
|
* `releaseName` String
|
|
* `releaseDate` Date
|
|
* `updateUrl` String
|
|
* `quitAndUpdate` Function
|
|
|
|
Emitted when update has been downloaded, calling `quitAndUpdate()` would restart
|
|
the application and install the update.
|
|
|
|
## autoUpdater.setFeedUrl(url)
|
|
|
|
* `url` String
|
|
|
|
Set the `url` and initialize the auto updater. The `url` could not be changed
|
|
once it is set.
|
|
|
|
## autoUpdater.checkForUpdates()
|
|
|
|
Ask the server whether there is an update, you have to call `setFeedUrl` before
|
|
using this API.
