closurecompiler.js's Issues

installing from behind proxy trough npm on windows fails

I'm getting following error when installing closurecompiler from behind a proxy on windows
HTTPS_PROXY and HTTP_PROXY environment variables are set correctly.

Going trough the code i think you should probably configure the proxy using system variables somewhere about here:

Closure now requires Java 7 

  Configuring JRE ...
  ✔ Global Java is available, perfect!

Except it won't work if that's Java 6, as the compiler now requires Java 7 (not sure which version the bundled JRE is but it might need updating too).

Accept a Buffer in addition to files in `.compile()`

I've created a gulp plugin for Closure Compiler using this excellent module.

Gulp works on streams and buffers and not files while this module requires you to supply files. A lot of other Node things does this too.

It would be useful if you could also supply a buffer that is passed to the Closure Compiler stdin.

Like:

ClosureCompiler.compile(new Buffer('function foo() {}'), {}, function () {});

Error: Unable to access jarfile

Right after install I get an error:

C:\Users\xxx\Desktop\xxx\public\js\jquery\dist>ccjs jquery.js
Error: Unable to access jarfile
C:\Users\xxx\AppData\Roaming\npm\node_modules\closurecompiler/compiler/compile r.jar

What does this mean?

Incredibly slow?

I'm running this on a local installation of Node.js and it takes an unholy amount of time on even simple, small scripts. Is this to be expected or is there something wrong with my setup?

Bump for npm

I noticed that the version of closure compiler has been updated but not the npm package.

Upgrade tar version

The current version of tar being used has a vulnerability.

Overview

The tar module earlier than version 2.0.0 allow for archives to contain symbolic links that will overwrite targets outside the expected path for extraction.

Remediation

Update to a version 2.0.0 or greater

1.5.3 and previous are broken

It seems like the name of the downloaded jar has changed from compiler.jar to closure-compiler-v20160713.jar. The older versions of ClosureCompiler.js look for compiler.jar explicitly while 1.6.0looks for closure-compiler*. For users that specify their dependency on this library as ^1.5.3 or ~1.5.3, or any version below, the library doesn't work. It might make sense to pull in the jar finding code that was added in 1.6.0 to a 1.5.x minor so as not to break frozen builds.

This might not be the best solution and I'm sure you aren't totally in control of this but thought I would put it here for others.

Install failing for ^1.6.1

Blocking issue please take action

Installing the package calls the following URL which now returns 503:

Carriage return in shebang line in version from npm

When installing from NPM, the shebang line of ccjs is #!/usr/bin/env node\r\n

The carriage return makes it fail. Invocation fails with the message

env: node\r: No such file or directory”
         ^^^

The source version does not suffer from this problem, so maybe the publishing pipeline introduces the problem somehow.

Out of memory error

I'm facing out of memory error on my laptop running OS X Yosemite with 16 gigabyte of RAM.
I've intentded to compile my javascript app (172k lines). I've tried both SIMPLE_OPTIMIZATION and ANDVANCED_OPTIMIZATION.

My question on StackOverflow

When running ccjs from the command line, it will return exit status "0" (Success) even when there were errors.

It should return some other exit status to indicate an error

Lost in Callbacks?

Hey,

today I just rewritten my gulp plugin that uses your awesome ClosureCompiler.js library, and the code it's much better, readable and gulp-friendly as well (no dirty hacks!).

But I'm having a strange issue: when I call my single 'js' task as gulp js everything works good; If i try to call all the tasks using gulp, somehow your callback gets lost.

Maybe you know something that I'm missing?

Source code of my plugin: https://github.com/julianxhokaxhiu/gulp-closurecompiler/blob/master/gulp-closurecompiler.js

Gulp example configuration:

// Compile and uglify Javascript
gulp.task('js', function() {
    return gulp
    .src(
        'assets/js/*.js'
    )
    .pipe(
        gulpCC({
            fileName: 'main.js'
        })
    )
    .pipe(
        gulp.dest( 'assets/out/js/' )
    )
});

gulp.task('clean', [
    ...
    'js',
    ...
], function(cb){
    del([
        'assets/tmp'
    ], cb);
});

gulp.task('default', [
    'clean'
]);

Thanks in advice for any help :)

New google closure compiler jar file naming

Due to release notes July 13, 2016 there is new compiler jar file naming system. There should be added something like

//line 166
 var compilerFile = '';
        fs.readdirSync(__dirname + '/compiler').forEach(function(file) {
            if (file.indexOf('closure-compiler') !== -1) {
                compilerFile = file;
            }
        })
        var args = ['-XX:+TieredCompilation'];
            if (xms) args.push('-Xms'+xms);
            args.push(
                '-Xmx'+xmx,
                '-jar', __dirname+'/compiler/' + compilerFile
            );

into ClosureCompiler.js

configure.js download function does not work behind a proxy

The problem is in the following:

function download(downloadUrl, filename, callback, ondata) {
    var url = require("url").parse(downloadUrl);
    var out = require("fs").createWriteStream(filename, { flags: 'w', encoding: null, mode: 0666 });
    var bytes = 0, total = -1;
    var req = require(path.join(__dirname, "..", "lib", "follow-redirects.js")).http.request({
        "hostname": url["host"],
        "method": "GET",
        "path": url["path"],
        "agent": false
    }, function(res) {
        if (res.headers["content-length"]) {
            total = parseInt(res.headers["content-length"], 10);
        }
        if (res.statusCode != 200) {
            res.setEncoding(null);
            callback(new Error("Download failed: HTTP status code "+res.statusCode), -1);
            return;
        }
        res.on("data", function(chunk) {
            bytes += chunk.length;
            if (ondata) ondata(chunk.length, total);
            out.write(chunk);
        });

        res.on("end", function() {
            callback(null, bytes);
        });
    });
    req.on("error", function(e) {
        callback(e, -1);
    });
    req.end();
}

Particularly:

 var req = require(path.join(__dirname, "..", "lib", "follow-redirects.js")).http.request({
        "hostname": url["host"],
        "method": "GET",
        "path": url["path"],
        "agent": false

where the hostname and path are ignoring the proxy.

Error: Cannot find module './*.js'

Hi,

my project has the following structure:

index.js
compile.js
lib/
-- Class1.js
-- Class2.js
package.json

In compile.js the compiler is invoked with index.js and all files in the lib-directory as source files. Compilation works as expected.

But when I invoked the compiled source file, cross-references between Class1.js and Class2.js cannot be found. The following error occurs:

module.js:340
throw err;
^
Error: Cannot find module './Class1.js'

In Class2.js there is a reference to Class1.js with require(''./Class1.js').

I could use absolute paths by setting an environment-variable in index.js and reading this in every require-statement. But I would like to know which is the best-practice solution for this problem.

jsdoc dependency notation vs NPM 2.x

Hey,

I was trying to install your package this morning using latest NPM 2.1.7 and I encountered this error:

npm ERR! notarget No compatible version found: jsdoc@'>=3.3.0 <3.4.0'
npm ERR! notarget Valid install targets:
npm ERR! notarget ["0.0.0","3.2.0-dev","3.2.0","3.2.1","3.2.2","3.3.0-alpha1","3.3.0-alpha2","3.3.0-alpha3","3.3.0-alpha4","3.3.0-alpha5","3.3.0-alpha7","3.3.0-alpha8","3.3.0-alpha9","3.3.0-alpha10"]
npm ERR! notarget
npm ERR! notarget This is most likely not a problem with npm itself.
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.

Reading elsewhere I found that this is an issue that was changed between NPM 1.x and 2.x. I've found also someone that already fixed it for both of them, you can see the issue here: krampstudio/grunt-jsdoc#102

Can you fix also yours?

Thanks in advice.

Link to jre package is outdated

Hi.

Link in the jrePrefix is no longer valid. Files are located now under https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/bundled-openjdk-jre/.

download 404

in lib/follow-redirects.js line 128:

`
// Make a new option object for next request from old options object
// Break url in parts
var searchname = url.parse(redirectUrl).search;
var hostname = url.parse(redirectUrl).hostname;
var pathname = url.parse(redirectUrl).pathname;

var redirectOptions = options;
redirectOptions.reqUrl = redirectUrl;
redirectOptions.hostname = hostname;
redirectOptions.path = pathname + searchname;

var out = module.exports[proto].get(redirectOptions, redirectCallback(reqUrl, redirect), redirect);
`

when searchname is null ,it will download from http://120.52.72.22:80/dl.google.com/c3pr90ntc0td/closure-compiler/compiler-latest.tar.gznull

please fix this bug with :

redirectOptions.path = pathname + (searchname? searchname: '');
