Webogram – UNOFFICIAL Telegram Web App

Telegram offers great apps for mobile communication. It is based on the MTProto protocol and has an Open API. I personally like Telegram for its speed and cloud-support (that makes a web app possible, unlike in the case of WA and others).

MTProto data can be carried over HTTP, but no official web-version for Telegram exists for the time being. So this project is my take at creating one.

Disclaimer: This is an alpha version of the Telegram UNOFFICIAL web application. It may have undetected security issues, and there is definitely a load of bugs to fix, features to add and so on. So if you want 200% secure and fully functional communication, don't use this yet! You can always find Telegram official mobile applications here: https://telegram.org

That said, I'm using this app myself and I'd like to share its sources, so anyone can contribute to the development. Any help is welcome!

Maintained locations

Description	URL	Type
Online Web-version (hosted on Telegram servers)	http://web.telegram.org/	hosted
Online Web-version (hosted on GitHub pages)	http://zhukov.github.io/webogram	hosted
Chrome Web Store	https://chrome.google.com/webstore/detail/telegram/ clhhggbfdinjmjhajaheehoeibfljjno	packed
Firefox & FirefoxOS Marketplace	https://marketplace.firefox.com/app/telegram	packed

Hosted version: the app is downloaded via HTTP as a usual website.

Packed version: the app is downloaded at once in a package via HTTPS. This is a more secure way to use app, but the package is updated less frequently than the Web-version.

All of the apps above are submitted and maintained by @zhukov, so feel free to use them and report bugs here. Please do not report bugs which reproduce only in different locations.

Technical details

The app is based on AngularJS JavaScript framework, written in pure JavaScript. jQuery is used for DOM manipulations, and Bootstrap is the CSS-framework.

Contribute to the code

If you know how to code, we welcome you to send fixes and new features, but in order to be efficient we ask you to follow the following procedure:

• Fork this repo using the button at the top.
• Clone your forked repo locally.

$ git clone git@github.com:yourname/webogram.git

• Don't modify or work on the master branch, we'll use it to always be in sync with webogram upstream.

$ git remote add upstream git@github.com:zhukov/webogram.git
$ git fetch upstream

• Always create a new issue when you plan to work on a bug or new feature and wait for other devs input before start coding.
• Once the new feature is approved or the problem confirmed, go to your local copy and create a new branch to work on it. Use a descriptive name for it, include the issue number for reference.

$ git checkout -b improve-contacts-99

• Do your coding and push it to your fork. Include as few commits as possible (one should be enough) and a good description. Always include a reference to the issue with "Fix #number".

$ git add .
$ git commit -m "Improved contact list. Fix #99"
$ git push origin improve-contacts-99

• Do a new pull request from your "improve-contacts-99" branch to webogram "master".

How do changes suggested on a pull request

Some times when you do a PR, you will be asked to correct some code. You can do it on your work branch and commit normally, PR will be automatically updated.

$ git commit -am "Ops, fixing typo"

Once everything is OK, you will be asked to merge all commit messages into one to keep history clean.

$ git rebase -i master

Edit the file and mark as fixup (f) all commits you want to merge with the first one:

pick 1c85e07 Improved contact list. Fix #99
f c595f79 Ops, fixing typo

Once rebased you can force a push to your fork branch and the PR will be automatically updated.

$ git push origin improve-contacts-99 --force

How to keep your local branches updated

To keep your local master branch updated with upstream master, regularly do:

$ git fetch upstream
$ git checkout master
$ git pull --rebase upstream master

To update the branch you are coding in:

$ git checkout improve-contacts-99
$ git rebase master
