Thanks! Could we use isValidUrl?

transformers.js/src/utils/hub.js

Line 177 in b125e82

function isValidUrl(string, protocols = null, validHosts = null) {

for this?

Example usage:

transformers.js/src/utils/hub.js

Line 217 in b125e82

if (env.useFS && !isValidUrl(urlOrPath, ["http:", "https:", "blob:"])) {
