How can you use console.log() effectively in an Angular application?

While debugging an Angular project, I have encountered a situation where console.log() does not seem to be working properly despite ensuring that all logging levels are enabled in the Chrome console settings. I have tried placing the console.log() statement in various locations within the code, including the constructor of a class, but still no output is produced.

An interesting observation I made is that changing console.log() to console.error() actually allows me to see output in the Chrome console. Does anyone have any suggestions on how to resolve this issue?

Answer №1

Experiment by inserting a predefined string in console.log such as "console.log("something") and verify if it displays. Alternatively, insert "debugger" into your code to halt execution at a specific point. This will confirm whether the program is reaching that particular section of code or not. Then, open the developer tools with F12 and run the application.

Answer №2

It is possible that the Logging level has been enabled. If you want to disable it, you can refer to the code snippet below.

if (environment.production) {
    enableProdMode();
}`

There could be a chance that logging is disabled at the lint level. Disabling it at the lint level may remove lower log levels during the execution of ng lint --fix. Please review your tslint config for more information.

ng lint --fix

For additional information: Is it possible to strip all comments and console.logs with ng build --prod?
