How does kibana regenerate the target file

I want to modify one of kibana's index.js files, but running the modification does not take effect. Looking at the browser, I find that the browser is loading the target file. How to recompile the index.js file to generate a new target file

Hi, the developer guide will show you how to get started: Getting started | Kibana Guide [master] | Elastic

HI,I'm not trying to build a development project,I want to change the project that has been builded,Can it be realized?

Nope, sorry. I can't think of any way that would be worth the time, vs just building the project that you need from source.
