Encounter Vue instance method breakpoint following npm build

Exploring Vue.js for the first time has been a delightful experience. The transition from using JQuery, where manual work was necessary and inefficient, to Vue.js has been smooth. A major advantage of JQuery was being able to debug the code easily in the Chrome debugger, adding breakpoints wherever needed to analyze the application.

Now with Vue.js, utilizing vue-cli and npm to create and build the Vue application that compiles the app code into dist/build.js, I encountered an issue within a method of one Vue component. While no errors are visible, the expected behavior is not occurring as intended.

Is there a way to insert a breakpoint specifically within this method to observe its input, execution flow, and step-by-step progression?

Upon inspection, it appears that the source code I wrote within the Vue component resides inside build.js, compressed within a lengthy string enclosed within an eval function.

Answer №1

If you need to troubleshoot your js applications, consider inserting a debugger statement in your code - this will create breakpoints for easier debugging.

The debugger statement is useful for activating debugging functions like setting breakpoints. In cases where no debugging tools are available, this statement will have no impact on the code execution.
