V2: FATAL if non-md files (e.g., images) also found in Source Content Folders

Is your feature request related to a problem? Please describe

This issue was encountered in #1049. The Content Module fills up the terminal with loads of warnings if the Source Content Folder has images as well. This is especially irksome when the Source Folder is being sourced from elsewhere (using multi-sources feature), where the markdown files live along side the images.

This happens even if no querying is done on the Folder, but the Folder remains in nuxt.config’s Content’s sources

---

EDIT: This is not only about warnings, but even on reloading the page (while the terminal is being filled and filled), the page keeps reloading for half a minute. So, kindly not only reduce the warnings, but also ignore the files quickly if they are not md.

EDIT: If while the page is being reloaded (due to huge no. of images in the Source Folder, the page reloads for such a long time), the app is saved with some changes the queryContent, this happens. The following happened twice.

Describe the solution you’d like

• Just show one warning that images were found inside the Folder, that’s it.
  • Don’t show same kind of warning for thousand times for thousand images.
• Ignore the images quickly instead of blocking the entire app and crashing it again and again.
  • Note, this issue goes away if I remove the particular folder with many images from my Sources.

@farnabaz It gives this error

 ERROR  [worker reload] [worker init] Invalid regular expression: /^*\.png/: Nothing to repeat

Your inline suggestion of .*\\.png works perfectly; the one given in block code doesn’t work. Kindly update it. 😀

@farnabaz What should be the regex to ignore every file except the one containing in its name “publish”?

For example,

• name.publish.md KEEP
• name.md IGNORE
• name.yml IGNORE
• name.publish.yml KEEP

I tried using negative lookahead, but it ignores everything, and doesn’t work.

content: {
    ignores: [".*\\.(?!publish\\.(?:md|yml|csv))"],
}

Use case: I have 8000 notes; I don’t want the Module to scan everything, when I intend to publish on website only handful of these.
