I'm curious about something as a beginner. Can you explain what **.config.js and **.vue.js files are? How do they differ from regular .js files

I have a simple question that I haven't been able to find the answer to through searching. I've come across files like vue.config.js generated by vue-cli, as well as files like Content.vue.js. At first, I assumed that after the period was the file extension. How is it possible for these files to have two periods? What sets .config.js and .vue.js files apart from standard .js files? And when should they be used?

Thank you!

Answer №1

I believe that embracing a more flexible perspective on file extensions can be beneficial. File extensions are not absolute entities, but rather optional indicators provided by the creator to suggest the content or format of a file. Files may exist without any extensions at all, or solely as an extension (such as dotfiles used for configuration, like .gitignore or .bashrc).

In the case of vue.config.js, the creator chose to use the "extension" .config.js as a suggestion for the file's content. There is no strict rule prohibiting multiple periods in the extension, so it is entirely acceptable.
