Error when calling kuroshiro init [invalid file signature] even though files are found

some server auto decompress .gz in response (ex: python django), so just modify kuromoji/src/loader/BrowserDictionaryLoader.js and build your own js

BrowserDictionaryLoader.prototype.loadArrayBuffer = function (url, callback) {
    var xhr = new XMLHttpRequest();
    xhr.open("GET", url, true);
    xhr.responseType = "arraybuffer";
    xhr.onload = function () {
        if (this.status > 0 && this.status !== 200) {
            callback(xhr.statusText, null);
            return;
        }
        var arraybuffer = this.response;

        //var gz = new zlib.Zlib.Gunzip(new Uint8Array(arraybuffer));
        //var typed_array = gz.decompress();
        callback(null, arraybuffer);
    };
    xhr.onerror = function (err) {
        callback(err, null);
    };
    xhr.send();
};

Also look into the browser you use which may cause the error. @hexenq i have test in all browser im having the same issue. for a strange reason dict files is loading on index page . but when i go to other pages. this .dat.gz files doens load files at all. i get 404 not found error . this should be fixed. i dont think it has to do with my browser .

the error is coming from this line of code

},{"./TokenizerBuilder":4,"./dict/builder/DictionaryBuilder":14}],16:[function(require,module,exports){
"use strict";var zlib=require("zlibjs/bin/gunzip.min.js"),DictionaryLoader=require("./DictionaryLoader");function BrowserDictionaryLoader(r){DictionaryLoader.apply(this,[r])}BrowserDictionaryLoader.prototype=Object.create(DictionaryLoader.prototype),BrowserDictionaryLoader.prototype.loadArrayBuffer=function(r,e){var o=new XMLHttpRequest;o.open("GET",r,!0),o.responseType="arraybuffer",o.onload=function(){if(this.status>0&&200!==this.status)e(o.statusText,null);else{var r=this.response,t=new zlib.Zlib.Gunzip(new Uint8Array(r)).decompress();e(null,t.buffer)}},o.onerror=function(r){e(r,null)},o.send()},module.exports=BrowserDictionaryLoader;
