In node.js, can I list files with wild card matching like

 fs.readdirSync('C:/tmp/*.csv')?

I did not find the information on wild card matching from the fs documention.

This is not covered by Node core. You can check out this module for what you are after. npmjs.org is also a great resource for finding various modules.

Usage

var glob = require("glob")

// options is optional
glob("**/*.js", options, function (er, files) {
  // files is an array of filenames.
  // If the `nonull` option is set, and nothing
  // was found, then files is ["**/*.js"]
  // er is an error object or null.
})
