 ## Component Lifecycle Hooks
 
-Since there are no dynamic updates, of all the lifecycle hooks, only `beforeCreate` and `created` will be called during SSR. This means any code inside other lifecycle hooks such as `beforeMount` or `mounted` will only be executed on the client.

 Another thing to note is that you should avoid code that produces global side effects in `beforeCreate` and `created`, for example setting up timers with `setInterval`. In client-side only code we may setup a timer and then tear it down in `beforeDestroy` or `destroyed`. However, because the destroy hooks will not be called during SSR, the timers will stay around forever. To avoid this, move your side-effect code into `beforeMount` or `mounted` instead.
