Package Exports

wget-improved-2
wget-improved-2/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (wget-improved-2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

wget-improved

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

download(src, output, options)

const wget = require('wget-improved');
const src = 'http://nodejs.org/images/logo.svg';
const output = '/tmp/logo.svg';
const options = {
    // see options below
};
let download = wget.download(src, output, options);
download.on('error', function(err) {
    console.log(err);
});
download.on('start', function(fileSize) {
    console.log(fileSize);
});
download.on('end', function(output) {
    console.log(output);
});
download.on('progress', function(progress) {
    typeof progress === 'number'
    // code to show progress bar
});

request(options, callback)

const wget = require('wget');
const options = {
    protocol: 'https',
    host: 'raw.github.com',
    path: '/Fyrd/caniuse/master/data.json',
    proxy: 'http://host:port',
    method: 'GET'
};
let req = wget.request(options, function(res) {
    let content = '';
    if (res.statusCode === 200) {
        res.on('error', function(err) {
            console.log(err);
        });
        res.on('data', function(chunk) {
            content += chunk;
        });
        res.on('end', function() {
            console.log(content);
        });
    } else {
        console.log('Server respond ' + res.statusCode);
    }
});

req.end();
req.on('error', function(err) {
    console.log(err);
});

options

options = {}
    // Set to true to have any gzip stream automatically decompressed before saving
    options.gunzip = false;
    options.proxy = {};
        options.proxy.protocol = 'http';
        options.proxy.host = 'someproxy.org';
        options.proxy.port = 1337;
        options.proxy.proxyAuth = '{basic auth}';
        options.proxy.headers = {'User-Agent': 'Node'};

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 provide content-length

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!
