wget-improved

CircleCI

wget-improved simplifies retrieving files from any URL

Improvements over wuchengwei/node-wget

  • Handles 3xx 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

Install

npm install wget-improved --save

Changes from 2.0.0 to 3.0.0

Progress is now returned as a Number instead of a String

On start filesize can return null when the remote server does not provided content-lenth

Exception for not specifying protocol is now: Your URL must use either HTTP or HTTPS.

Supports handling redirects that return a relative URL.

You can now get events for the total number of bytes downloaded download.on('bytes', function(bytes) {}...)

Request headers can be specified by passing an object to options.headers.

Unit tests have been added for most download functionality and error cases. Tests are a requirement for all PRs going forward!
