Vue.js (2.0) | ||
============ | ||
|
||
.. sentry:support-warning:: | ||
This plugin only works with Vue 2.0 or greater. | ||
|
||
|
||
To use Sentry with your Vue application, you will need to use both Raven.js (Sentry's browser JavaScript SDK) and the Raven.js Vue plugin. | ||
|
||
On its own, Raven.js will report any uncaught exceptions triggered from your application. For advanced usage examples of Raven.js, please read :doc:`Raven.js usage <../usage>`. | ||
|
||
Additionally, the Raven.js Vue plugin will capture the name and props state of the active component where the error was thrown. This is reported via Vue's `config.errorHandler` hook. | ||
|
||
Installation | ||
------------ | ||
|
||
Raven.js and the Raven.js Vue plugin are distributed using a few different methods. | ||
|
||
Using our CDN | ||
~~~~~~~~~~~~~ | ||
|
||
For convenience, our CDN serves a single, minified JavaScript file containing both Raven.js and the Raven.js Vue plugin. It should be included **after** Vue, but **before** your application code. | ||
|
||
Example: | ||
|
||
.. sourcecode:: html | ||
|
||
<script src="https://cdn.jsdelivr.net/vue/2.0.0-rc/vue.min.js"></script> | ||
<script src="https://cdn.ravenjs.com/3.4.1/vue/raven.min.js"></script> | ||
<script>Raven.config('___PUBLIC_DSN___').install();</script> | ||
|
||
Note that this CDN build auto-initializes the Vue plugin. | ||
|
||
Using package managers | ||
~~~~~~~~~~~~~~~~~~~~~~ | ||
|
||
Both Raven.js and the Raven.js Vue plugin can be installed via npm and Bower. | ||
|
||
npm | ||
```` | ||
|
||
.. code-block:: sh | ||
$ npm install raven-js --save | ||
Bower | ||
````` | ||
|
||
.. code-block:: sh | ||
$ bower install raven-js --save | ||
In your main application file, import and configure both Raven.js and the Raven.js Vue plugin as follows: | ||
|
||
.. code-block:: js | ||
import Raven from 'raven-js'; | ||
import RavenVue from 'raven-js/plugins/vue'; | ||
Raven | ||
.config('___PUBLIC_DSN___') | ||
.addPlugin(RavenVue) | ||
.install(); |
