which js libs to include for .epub? "zip not defined" about epub.js HOT 13 CLOSED

BTW here is what I have loaded now but not sure what order the scripts should be in. I moved it all to the bottom of the file where I think it should be.

        <script src="js/libs/jquery-1.9.0.min.js"></script>
        <script src="js/libs/loader_filesystem.min.js"></script>
        <script src="js/libs/inflate.min.js"></script>
        <script src="js/libs/zip.min.js"></script>



        <!-- Render -->
        <script src="js/epub.min.js"></script>

        <!-- Hooks -->
        <script async src="js/hooks.min.js"></script>

        <!-- Reader -->
        <script src="js/reader.min.js"></script>

        <!-- fileStorage -->
        <script src="js/libs/fileStorage.min.js"></script>

        <script>
            "use strict";

            document.onreadystatechange = function () {  
              if (document.readyState == "complete") {
                EPUBJS.VERSION = "0.1.6";

                EPUBJS.filePath = "js/";
                fileStorage.filePath = EPUBJS.filePath + "libs/";

                EPUBJSR.app.init("book/backbone_fundamentals.epub");
              }  
            };

          </script>

Sorry for the lack of documentation... working on getting it setup.

The zip library is:
http://gildas-lormeau.github.io/zip.js/
I should warn you that compressed epubs are not yet working in Safari either.

In regards the "Uncaught ReferenceError", Grunt was creating the minified version of the zip.js library out of order, which is now update in the latest commit.

Also, I believe the EPUBJS.filePath should be:

EPUBJS.filePath = "js/libs/";

Finally you shouldn't need to include inflate.min.js, as it is loaded by the zip worker.

from epub.js.

No problem on the docs. I appreciate it. This got me a little farther along but now zip.min.js is trying to load libs/zip/inflate.js resulting in a 404. If I copy inflate.js into libs/zip it gets past that and then gives me a type error

TypeError {} epub.min.js:1
(anonymous function) epub.min.js:1
y epub.min.js:1
(anonymous function) epub.min.js:1
v.trigger epub.min.js:1
(anonymous function) epub.min.js:1
(anonymous function) epub.min.js:1
(anonymous function) epub.min.js:1

I should clarify I just copied the demo directory to myproject hoping to be able to use it and just swap out the mobi-dick for my .epub so not sure if that may be the problem. I should really spend some time with the un-built source to learn more how this works I guess :-)

from epub.js.

I find that epub.js looks for http://localhost/epubjs/inflate.js 404 (Not Found) for the file rather than the location of inflate.js I put in the html.
I also find the example http://fchasen.github.io/epub.js/examples/contained.html is not working.

from epub.js.

It took me a while to figure out that EPUBJS.filePath = "../build/libs/" need to be set for the right location of inflate.js.

from epub.js.

zip.js requires the path to inflate.js and deflate.js to be set like so zip.workerScriptsPath = '/libs/'. See the zip.js docs

Epub.js does this in src/unarchiver.js which comes from EPUBJS.filePath.

There are two changes I think we could make to make this less confusing:

1. Rename EPUBJS.filePath to EPUBJS.libsPath to make it more clear that this needs to be the libs directory
2. Find a way to parse the loaded scripts tags to find inflate.js and deflate.js and use this to set zip.workerScriptsPath, eliminating the need to use EPUBJS.filePath

from epub.js.

Seems EPUBJS.cssPath can't use absolute path. EPUBJS.filePath also needs to be checked.

from epub.js.

Using JSZip mean we no longer need to include EPUBJS.filePath.
Only need to include the following now.
<script src="zip.min.js"></script>

from epub.js.

What's the advantage of JSZip?

from epub.js.

Glad you asked! I tried to update to the latest zip.js and ran into the issue you reported: gildas-lormeau/zip.js#115

JSZip is a little simpler to implement since it doesn't have to find a worker file, is under active development and heavily in use (at least by node libraries.)

from epub.js.

Which isn't to say that I'm opposed to switching back to zip.js at somepoint - it is a great library and has worked well with epubs so far. Moving between the two is a small tweak, but for the moment JSZIP simplifies fixing some of the zip related issues that have been coming up.

from epub.js.

I'm thinking that it may be better to keep epub.js as a simple epub parser lib and leave unzip, file storage, pagination and etc. to the application layer of the readers.

Hi @fchasen,
I use JSZIP to zip my unzipped epub file. But the output is not valid epub. I have all files in the output epub but when I use epubcheck for validating my epub it gives me the following errors:

ERROR(RSC-001): file.epub/file.epub(-1,-1): File 'OEBPS/image/3904.png' could not be found.

I have all of them in my book. Could you please help me with your thought?
Thanks in advance,
