There’s a common class of applications where rich experiences are needed, but full single-page applications are otherwise overkill to achieve the bits of required rich interaction. While modern JavaScript tooling enables sophisticated client applications, it often comes at an extreme cost in complexity and maintainability.
LiveView powered applications are stateful on the server with bidrectional communication via WebSockets, offering a vastly simplified programming model compared to JavaScript alternatives. We only handle sightings additions and we don’t even store them on a database nor broadcast it to all users.Phoenix LiveView is an exciting new library which enables rich, real-time user experiences with server-rendered HTML. Properly store and broadcast sightings creation, updates and deletions? Meaning that if the script is loaded after, the handleEvent function that creates markers won’t have access to the map and as such it will fail and won’t render the markers!
The problem here is that the Google Map script might be rendered before or after we call that pushEvent. One might think “this seems very easy, on the first mount we could send / schedule a pushEvent !”.
#Windows liveview how to
How to display on the map the already stored sightings? There are a few points that we will probably address in another article: We had to cut some corners for the sake of keeping the article focused on topic.
#Windows liveview code
If you apply all the changes and run the code you should now be able to randomly create markers on your map. # Longitude ranges between -180 and 180 degrees, inclusive # Latitude ranges between -90 and 90 degrees, inclusive. */Įxports.map = new (document.getElementById("map"), * Optional: Makes the sample page fill the window. * Always set the map height explicitly to define the size of the div The Maps JavaScript API lets you customise maps with your own content and imagery for display on web pages and mobile devices.įor you to get up and running, and have a page that displays a map centered in Sydney, you just need to do the following: Once again according to the documentation: Once the state changes, LiveView will re-render the relevant parts of its HTML template and push it to the browser, (…) LiveView does the hard work of tracking changes and sending the relevant diffs to the browser. The LiveView programming model is declarative: instead of saying “once event X happens, change Y on the page”, events in LiveView are regular messages which may cause changes to its state. LiveView provides rich, real-time user experiences with server-rendered HTML. We are assuming that you are familiar with Elixir and Phoenix. Understanding the technology 🤓īefore digging into the problem, let’s take a look at the technologies we are using. For example, we wanted administrators of the platform to be able to see, on a map, the sightings that the users of the app were reporting on certain places, as they happen. We have been building a platform where using LiveView made a lot of sense, since we wanted some of our features to use an interface that could be updated in real-time. And as soon as LiveView was announced, we could not wait to use it! Howdy dear reader 🖖🏽, hope you are safe and healthy during these troubled times.ĭuring the past 3 years, we have developed a few projects using the Phoenix Framework for Elixir.
