Dealing with Asynchronously Initialized Components
Explore techniques for dealing with asynchronously initialized components in Node.js, including local initialization checks and delayed startup methods. Learn how to handle modules that require asynchronous setup before usage, ensuring reliable and efficient application startup.
We'll cover the following...
One of the reasons for the existence of synchronous APIs in the Node.js core modules and many npm packages is that they’re handy to use for implementing initialization tasks. For simple programs, using synchronous APIs at initialization time can streamline things a lot, and the drawbacks associated with their use remain contained because they’re used only once, which is when the program or a particular component is initialized.
Unfortunately, this isn’t always possible. A synchronous API might not always be available, especially for components using the network ...
