Blocking the Event Loop
Thankfully, you can monitor the event loop to detect any anomalies by using proprietary solutions or open-source modules. Such tools can accurately and repeatedly track the time-spend between an interval and report the problem.
Wasting Time with Restarts
Developers can be slowed down when a language requires a restart after they have made alterations to a source-code. They can also be affected by the need to refresh a browser when the static code changes. Rather than doing those things manually, you can speed up the process by using existing tools to automate the tasks.
With the right modules, they can watch for file changes and automatically restart the browser on your behalf. These refreshes can be done either by injecting a script into the page or using a browser plugin.
Executing a Callback Several Times
Some developers think callback nesting is unavoidable, but that doesn’t have to be the case. There are various solutions available to make sure your code is neat and tidy. For instance, you can use control flow modules, promises, and generators.
The app will act as a naïve frontend resource analyzer that checks how many scripts, stylesheets, and images are in the code, outputs the total number to the terminal, and checks each resource’s content-length. It then pushes the total length of the resources to the terminal.
Creating Large Monolithic Applications
Other common mistakes developers make include not breaking things into their own modules and containing everything in a single file. By doing that, you will make it difficult to test and read the code. A little refactoring will easily solve that issue and make everything neater and more modular.
Not Carrying Out Tests
You should never consider your application to be finished if you haven’t written any tests for it. There is an abundance of tools you can use to test the proxy API. You can use testing frameworks, assertion modules, and code coverage tools.
