Installation
============

Raven is distributed in a few different methods, and should get included
after any other libraries are included, but before your own scripts.

So for example:

.. sourcecode:: html

    <script src="jquery.js"></script>
    <script src="https://cdn.ravenjs.com/###RAVEN_VERSION###/raven.min.js" crossorigin="anonymous"></script>
    <script>Raven.config('___PUBLIC_DSN___').install();</script>
    <script src="app.js"></script>

This allows the ability for Raven's integrations to instrument themselves. If
included before something like Angular, it'd be impossible to use for
example, the Angular plugin.

Using our CDN
~~~~~~~~~~~~~

We serve our own builds off of `Fastly <http://www.fastly.com/>`_. They
are accessible over both http and https, so we recommend leaving the
protocol off.

Our CDN distributes builds with and without :doc:`integrations <integrations/index>`.

.. sourcecode:: html

    <script src="https://cdn.ravenjs.com/###RAVEN_VERSION###/raven.min.js" crossorigin="anonymous"></script>

This version does not include any plugins. See `ravenjs.com
<http://ravenjs.com/>`_ for more information about plugins and getting
other builds.

Bower
~~~~~

We also provide a way to deploy Raven via `bower
<http://bower.io/>`_. Useful if you want serve your own scripts instead of
depending on our CDN and mantain a ``bower.json`` with a list of
dependencies and versions (adding the ``--save`` flag would automatically
add it to ``bower.json``).

.. code-block:: sh

    $ bower install raven-js --save

.. code-block:: html

    <script src="/bower_components/raven-js/dist/raven.js"></script>

Also note that the file is uncompresed but is ready to pass to any decent
JavaScript compressor like `UglifyJS
<https://github.com/mishoo/UglifyJS2>`_.

npm
~~~

Raven is also available as an npm package, `raven-js
<https://www.npmjs.com/package/raven-js>`_.

.. code-block:: sh

    $ npm install raven-js --save

.. code-block:: html

	<script src="/node_modules/raven-js/dist/raven.js"></script>

Note that if you intend to use Raven with Node, `raven-node <https://github.com/getsentry/raven-node>`_ is the client to use.


CommonJS
~~~~~~~~

To use Raven with CommonJS imports:

.. code-block:: javascript

	var Raven = require('raven-js')	;
	Raven
	    .config('___PUBLIC_DSN___')
	    .install();

ES2015 (ES6)
~~~~~~~~~~~~

To use Raven with ES2015 (ES6) imports:

.. code-block:: javascript

	import Raven from 'raven-js';
	Raven
	    .config('___PUBLIC_DSN___')
	    .install();

Requirements
~~~~~~~~~~~~

Raven supports IE8+ and all other modern browsers, and works in Web Workers.

Raven requires the browser JavaScript environment to provide:

- Either `XHR Level 2 <http://caniuse.com/#feat=xhr2>`_ (IE10+, all other modern browsers)
  or `XDomainRequest <https://developer.mozilla.org/en-US/docs/Web/API/XDomainRequest>`_ (IE8, IE9)
- A global ``JSON`` object with ``JSON.stringify`` (IE8+ `standards mode
  <http://msdn.microsoft.com/en-us/library/cc288325(VS.85).aspx>`_, all other modern browsers)

Raven does not support IE 7 or other older browsers which do not provide the required features listed above.
On those older browsers, Raven.js is designed to fail gracefully; including it on your page
will have no effect, but it won't collect and report uncaught exceptions.
