Feature Request

Allow turning off watch() for files inside node_modules

Use Case

Right now it's easy to get too many open files error. The main reason is node_modules often contributes a lot of files. While understanding sometimes this is useful when updating code, this is generally unnecessary. Users should be allowed to filter out certain directories to be watched.

I have exactly the same problem! It seems there was a fix commited some time ago:

Retated Issue:
#1316

However, its still broken for me. :(

I've tried solving this problem with adding node_modules to skip_render, but unfortunatelly this doesn't make a difference :(

The feature seems to be added in #2631
The documents will update soon.

I think #2631 does not resolve this issue.

#2631 is to exlude some dirs/files from visiting (=processing) only.

To prohibit Hexo from watching dirs/files,
the option ignored should be passed to chokidar.watch().
(Not ignore)

The calling chain is:

1. chokidar.watch() is called by watch() of hexo-fs with its options parameter.
2. watch() of hexo-fs is called by Box.prototype.watch() with this.options.
3. this.options of Box is generated by the constructor of Box.

So, to resolve this issue, set the options.ignored of an instance of Box.

A patch (under development) for this issue was:
master...seaoak:feature/allow-turning-off-reading-and-watching-for-specified-directories

I will continue to update this patch.
