wget-improved

wget-improved

wget-improved simplifies retrieving files from any URL

Improvements over wuchengwei/node-wget

  • Handles 302 redirects (including infinite redirect loops)
  • Passes URL parameters
  • Better error reporting
  • Does not write using append (uses w+ identical to wget)
  • Handles gzip compression, allow you to automatically gunzip the stream
