If you answered PageLive.mount/2, you get a gold star! Since mount/2 We need to register every time a browser connects, but only Processes in order to receive an :update message whenever new data Register/1 function that we can use to register browser connection Updates the prices of the companies every two seconds. I mentioned earlier in this post that there is a GenServer that Believe it or not, that was the hard part! Register the connection to receive updates
We now have requests being routed to FullstackWeb.PageLive instead ofįullstackWeb.PageController. If you see the same HTML rendered as before (withĭifferent prices), then our refactor was successful! Enable Live Updating The Phoenix server (since we’ve modified config/config.exs) and If you’ve done everything correctly, all we need to do now is restart Restart the server and refresh the browser Our implementation simply passes the responsibility of rendering toįullstackWeb.PageView, making sure to pass on the assigns it It is passed socket.assigns as its one argument. Render/1 is tasked with pushing the result of its function to theĬlient. Our implementation takes the provided socket and binds the list ofĬompanies in our fake database to companies in the socket’sĪssigns with the assign/2 function. As a return value, it expects a tuple containing the :ok Mount/2 is called when a new connection is established and is passed It expects us to define two functions: mount/2 and render/1. This will bring in all the functions necessary to set up a LiveView. render ( " index.html", assigns ) end end Add end def render ( assigns ) do FullstackWeb. It is not included with the main Phoenixĭependency so we need to specify that we need it in ourĪpplication. Add the dependencyįirst, we need to make sure that phoenix_live_view is included in Information-even statically-with LiveView. The first step in converting our conventional controller-drivenĪpplication is to get rid of the controller. In order to keep up with other traders, we need the new information

The time it will decrease by a similar amount.įurthermore, this GenServer acts as a PubSub. Two-thirds of the time, the price will increase by a randomĪmount between 0 and 0.2 percent of the current price one-third of Iterates through all 500 companies and generates a new price for theĬompany. Initializes a price attribute for the company. Initialized, it fetches basic company information from a database andīinds them to a companies variable that it keeps in state. Reality, a GenServer is running on a timer. For this sample application, that is abstracted away. I mentioned above that there is a process that fetches data from a Information to the user when it is received.

In theīackground, there is a process that fetches data from whatever pricing Price tracker for 500 stocks traded on the Nasdaq exchange. Our task is to convert a traditional controller-driven Phoenix app to Went over both during the meetup in case you want to see what’s If you watch the video above, you’ll see that I In part 2, we’ll add some interaction with theĪbility to comment.

This is a quick test app re-computing and Shortly after Phoenix LiveView was first released, I played around Technology and has the potential to change the way real-time web
