The result should look like the
Component to display a separate message. Create a new file in the named copy then import the types into the new file and create an object of type with two keys that holds the message details and holds the value of the current message index in the parent message list.code below. Fragment Copy With these pieces in place you can build the component functionality. The code below uses the type you wrote to describe the function parameters Extract and value using destructuring Render the message in a style container Finally export the component Copy Now it's time to use the component Import the component and render one for each element in the array Copy in browse In the browser you should now see each user's messages on the right side. It looks good but there is one last thing to add. You are building a tree view so the last part is to render the branches that connect each message to its user. Create a new file named Copy This component will take a.Property that indicates whether the message it is linked to is the first message in the list. Note this is why you need the key in the component. Insert the following component into this file Copy the code sni photo editing servies ppet above to render a branch with some neat magic. If you're interested in the functionality provided or want to better understand what's going on above there is amazing documentation covering all the classes used above. To complete this application, use the new component in Components to render a branch for each message. Copy Back to the browser. You will now see the branch for each message. Hover over the message to highlight the branch. Summary and next steps. In this article you built the front-end portion of a fully type-safe application. Along the way you set up a project setup to model and simulate your data and build components for your application. At this point the data and types in the application are static and manually built.

In later parts of this series you will use code generation to set up dynamic type definitions and work with dynamic data from the database. In the next article you will start building the settings database and initializing it in the project.
