| # Kiwix JS | ||
|
|
||
| Kiwix is an offline browser for Wikipedia, Stackexchange, Project Gutenberg, and other Web resources packaged as highly compressed ZIM | ||
| archives. For full information about the open-source Kiwix project, see our main Web site: https://www.kiwix.org/. | ||
|
|
||
| Kiwix JS is an official HTML5/Javascript implementation of the Kiwix software, principally targeting browser extensions or add-ons. You | ||
| can get the extension, completely free, from the Mozilla, Chrome and Edge extension stores (see [Store links](#officially-supported-platforms) below). | ||
| There is also a version, primarily intended for use within extensions, implemented as an offline-first Progressive Web App (PWA) | ||
| at https://browser-extension.kiwix.org/current/. For the dedicated, fully featured PWA based on Kiwix JS, please see https://pwa.kiwix.org. | ||
|
|
||
| To use Kiwix JS, you will need to obtain, completely free, a content archive (see [Usage](#usage)). Once you have this on your device, select it with the | ||
| file selector (Configuration page), or drag-and-drop it into the app, and start searching for article titles. No further Internet access is required to | ||
| read the archive's content. You can have the entire content of Wikipedia in your own language inside your device (including images and audiovisual content) | ||
| entirely offline. If your Internet access is expensive, intermittent, slow, unreliable, controlled or censored, you can still have offline access to this | ||
| amazing repository of knowledge, information and culture. | ||
|
|
||
| The Kiwix browser also works with other content in the [OpenZIM format](https://wiki.openzim.org/wiki/OpenZIM), and has support for [Zimit content](https://youzim.it/) | ||
| (based on the Web Archive format), but our main targets are Mediawiki-based content (Wikipedia, Wikivoyage, Wikitionary, etc.), StackExchange, Project | ||
| Gutenberg and TED Talks. | ||

|
|
||
| ## Usage | ||
|
|
||
| Install "Kiwix JS" from your browser's add-on store. This is the best way to get the extension, because it will be kept up to date automatically. If | ||
| you would rather not use a store, you can get a file-based version of the extension from http://download.kiwix.org/release/browsers/ (and follow | ||
| [instructions below](#installing-signed-or-unsigned-extension-files-in-chromium)), but you will have to update this manually. | ||
|
|
||
| Alternatively, you can bookmark or install the PWA version from https://browser-extension.kiwix.org/current/ (it will auto-update), or try our dedicated | ||
| PWA version at https://pwa.kiwix.org. To install the PWA (in Chromium browsers), go to Settings -> Apps -> Install this site as an app. | ||
|
|
||
| As mentioned above, the app requires at least one ZIM archive of offline content. You can download one from https://library.kiwix.org (this has a nice, | ||
| graphical interface and a preview of each ZIM archive) or from https://download.kiwix.org/zim/ (a more basic list of archives). You have to download | ||
| these separately, store them in your filesystem, and manually select them after starting the application (or you can drag-and-drop one into the app). | ||
|
|
||
| **Zimit-based archives** (available from the "zimit" directory on https://download.kiwix.org/zim/, or made yourself with [youzim.it](https://youzim.it/)), are | ||
| **now compatible** with this reader, as of v3.11.5, in modern browsers *if the reader is running in [ServiceWorker mode](#some-technical-details) as an offline-first PWA* | ||
| ([see below](#some-technical-details) for an explanation of what this means). If the app is running in any other mode, then only static content will be | ||
| viewable, and many Zimit ZIMs may not work at all when viewed statically. Our sister app https://pwa.kiwix.org has some more support for Zimit archives | ||
| in solder browsers. | ||
|
|
||
| ## Compatibility | ||
|
|
||
| Since the app is written in HTML/JavaScript, it should work in most recent browser engines and many older ones too, depending on the Content | ||
| Injection mode supported by the specific browser engine. Archives containing dynamic content (most non-Wikimedia archives) work much better | ||
| in ServiceWorker mode ([see below](#some-technical-details)), but unfortunately this is not available in many older browsers. If you wish to read such archives, we | ||
| would suggest that you upgrade to a browser that supports Service Workers (Chrome 58+, Firefox 61+ [not ESR versions], Edge 17+, Safari 11.3+). | ||
|
|
||

|
|
||
| ### Deprecated platforms | ||
|
|
||
| These platforms/browsers are deprecated. We still partially test against them, and we'll try to keep compatibility as long as it's not too complicated: | ||
|
|
||
| - Firefox OS >=1.2: needs to be installed manually on the device with WebIDE | ||
| - Microsoft Edge Legacy >=17: no extension available, but bookmark https://browser-extension.kiwix.org or https://pwa.kiwix.org | ||
| - Microsoft Edge Legacy 15-16: needs to run a bundled version of the source code in jQuery mode only | ||
| - Microsoft Internet Explorer 11: needs to run a bundled version of the source code in jQuery mode only | ||
|
|
||
| **_You can build a bundled version by running `npm install` and `npm run build` in the root directory of this repo._** Alternatively, a bundled version is served | ||
| as a web app for testing from https://kiwix.github.io/kiwix-js/dist/ (also available on the `gh-pages` branch of this repo, under `/dist`). | ||
|
|
||
| ### Installing signed or unsigned extension files in Chromium | ||
|
|
||
| If you need to install Chromium (Chrome or Edge) extension from a file instead of from a Store, e.g. if your browser doesn't support Manifest V3, then you will need to download a | ||
| signed or unsigned CRX or ZIP file from a relevant directory in https://download.kiwix.org/release/browsers/, or else a nightly version from https://download.kiwix.org/nightly/. | ||
| Files with `mv2` in their filename are in the legacy Manifest V2 format. | ||
|
|
||
| To install your CRX or ZIP, open the extension management page in your browser, e.g. chrome://extensions/ or edge://extensions/, and turn on Developer mode. Now, you should be | ||
| able to drag and drop the ZIP file into this page. Verify the extension is showing in the management page. | ||
|
|
||
| Files that we deliver with a `.crx` file extension are files that have been validated by the Edge or Chrome Stores, and you should be able to install these as "first-class" apps. | ||
| ZIP files provided in https://download.kiwix.org/release/browsers/, or the ones labelled `signed` in nightly, are actually signed CRX files that have been renamed with a `.zip` | ||
| extension to facilitate downloading and installing them in Chromium browsers. Although signed, you cannot install them as CRX files, because they have not been validated by the | ||
| Chrome or Edge Stores. **_For this reason, the browser will periodically ask you if you want to turn off developer-mode extensions. Just choose "ask again in two weeks"._** | ||
|
|
||
| If drag-and-drop is difficult, you can instead unzip the extension ZIP into a folder, and note the location. Then select "Load unpacked" and choose the folder that contains the | ||
| unzipped extension. To unzip the MV2 files with a utility like 7Zip, you will need to change the extension name to `.crx`. On Linux, `unzip` can read them without changing the filename. | ||
|
|
||
| ## Some technical details | ||
|
|
||
| Technically, after reading an article from a ZIM file, it is necessary to "inject" the dependencies (images, css, etc). For compatibility reasons, | ||
| there are two main ways of doing this: | ||
|
|
||
| - "ServiceWorker" mode (the default) uses a Service Worker to catch any HTTP request the page may send and reply with content read from | ||
| the ZIM file. It is a generic and clean way of serving content to the browser. It works in any recent browser, but not in older ones. | ||
| Service Workers are currently disabled by Mozilla in Firefox extensions, and in Chromium extensions active content is severly restricted | ||
| for security reasons. In both cases we offer a functional workaround (an offline-first PWA version) as a substitute within the extension; | ||
| - "ServiceWorkerLocal" mode is a restricted ServiceWorker mode that is available only in Chromium extensions running fully locally. Chromium | ||
| extensions running locally block (by design) a lot of dynamic content such as inline JavaScript and `eval`, which means this mode won't work | ||
| with some modern dynamic content, and in particular, it won't work with Zimit-based archives (if you open one of these in this mode, you | ||
| will be thrown back to JQuery mode in order to view static content). However, this mode is useful if you cannot access the offline-first PWA, | ||
| and should work with most official Kiwix ZIM archives; | ||
| - "JQuery" mode (deprecated) parses the DOM to find the HTML tags of the dependencies and modifies them to point to content we extract from the ZIM. | ||
| This mode is compatible with any browser, but it cannot run JavaScript inside the ZIM file, so ZIMs with dynamic content do not work well (if at all). | ||
| If you open a dynamic (including Zimit) archive in this mode (or if you are thrown into the mode due to another incompatibility), then we will do our | ||
| best to display static content, but much functionality is likely to be broken. However, Mediawiki-based content (e.g. Wikipedia) works fine in this mode. | ||
|
|
||
| You can switch between these content injection modes in Configuration, but if your browser supports ServiceWorker mode as an offline-first PWA, you are | ||
| strongly advised to remain in this mode. | ||
|
|
||
| ### Limitations | ||
|
|
||
| It is not yet technically possible automatically re-open a selected ZIM file between sessions. However, browsers that support the File System Access API | ||
| or the `webkitdirectory` property of the File API, allow you to re-open a folder or directory of ZIMs with a quick permission prompt. Another alternative | ||
| is to drag-and-drop a ZIM file into the app. There are [versions of this app](https://kiwix.github.io/kiwix-js-pwa/app) that have experimental support for | ||
| the Origin Private File System, or that use frameworks like Electron, which do have the capability of remembering the chosen archive between app launches. | ||
|
|
||
| The app has fast title search, and slower full-text search for ZIM archives that have a full-text index, thanks to the | ||
| [openzim/javascript-libzim](https://github.com/openzim/javascript-libzim) project. Currently, full-text searching only works in browsers | ||
| that support [Atomic Operations](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Atomics), which means | ||
| recent desktop versions of Chromium and Firefox. There is also support in Safari on iOS 15+. | ||

||
| ## Public releases and nightly builds | ||
|
|
||
| The browser extensions are distributed through the stores of each vendor (see links above). But the packages are also saved in https://download.kiwix.org/release/browsers/ if necessary. | ||
|
|
||
| Some nightly builds are generated, and should only be used for testing purpose: https://download.kiwix.org/nightly/. | ||
|
|
||
| There is a test implementation of the latest code at https://kiwix.github.io/kiwix-js/ (unbundled: needs a modern browser that suppors native ES6 modules), and a bundled version for any | ||
| HTML5 browser (>=IE11) at https://kiwix.github.io/kiwix-js/dist/, but these implementations are used for development, and may be buggy, experimental or unstable. A stable PWA version for | ||
| use in the browser extensions is available from https://browser-extension.kiwix.org/current/. | ||
|
|
||
| ## Previous versions | ||
|
|
||
| The first versions of this application were originally part of the Evopedia project: http://www.evopedia.info (discontinued). There was an "articles nearby" feature, that was able to find articles around your location. It has been deleted from the source code with everything related to Evopedia (but still in git history in versions<=2.0.0). | ||
|
|
||
| These first versions were targeting Firefox OS (discontinued too: we're not lucky ;-) ). | ||
|
