javascript - Why are runtime.js, styles.js created on ng serve command

Question

Greetings fellow programmers

I am new to angular and I wanted to know why are these two files created when I run ng serve command.

these are the files

I know why other 3 files are created (main.js, polyfills.js, vendor.js) but I don't know about the 2 files I mentioned (runtime.js, styles.js)

I tried googling it too but no information came on these two files.

Any help is appreciated.

Answer 1

I am not good in explanation but let me give my understanding on these things. Its basically webpack (AOT compailer) configuration which continuously watch your changes on code, if change detect its compile all files and convert in minimized version.

1. runtime.js : Contains all files (Component, module, services, pipes, etc.) convert into js and transform into minimized version.
2. styles.js : same for css files.

i hope you get idea from this.
