A while back, I wrote about how ngrxLet<\/code> is an improved version of the async pipe<\/a>. I also covered how to use skeleton loaders with Angular<\/a>.<\/p>\n\n\n\n

Today, let’s look at how we can use these two tools to display a “loading” template while an observable is waiting for data.<\/p>\n\n\n\n

As a reminder, here is how ngrxLet<\/code> can be used to track different observable events<\/a>:<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

In the above code snippet, we receive the values emitted by the number$<\/code> observable in a variable n<\/code>. We would receive any error in a variable e<\/code>. We would receive the completion status (true<\/code> or false<\/code>) in a variable c<\/code>.<\/p>\n\n\n\n

Here is how we can pass a custom loading template to ngrxLet<\/code> using a template reference variable<\/a>:<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

Of course, the loading template can be customized with anything you want, including a skeleton loader or an animated gif image. That feature is called a suspense template<\/a>, and an observable is in a suspense state until it emits its first event (next<\/code>, error<\/code>, or complete<\/code> as covered here<\/a>). <\/p>\n","protected":false},"excerpt":{"rendered":"
