Is it advisable to include async before the created method in Vue.js? Won't this disrupt the Vue life cycle since using async makes it an asynchronous action that gets sent to the background queue, potentially allowing methods like mounted to execute before the created method is completed?
When using the
asynckeyword, the function is converted into an asynchronous action and sent to the queue in the background.
This is not entirely true. The function does not run in the background or get deferred to a later time; rather, its body starts executing immediately. The main difference is that it can await something, at which point the async function returns a promise for its eventual result after the awaited task finishes. However, Vue does not pay attention to this returned promise (or any return value).
Therefore, code following the await statement may appear to run out of order, after another hook like mounted is called, but it still runs synchronously at that point. In simpler terms, if mounted relies on data from created, it must be done synchronously. This can still be achieved at the beginning of an async function.
In essence, there isn't much difference between creating a promise chain in a created method without utilizing async.
