Vector/Web
==========
Vector is a Matrix web client built using the Matrix React SDK (https://github.com/matrix-org/matrix-react-sdk).
Getting Started
===============
The easiest way to test Vector is to just use the hosted copy at https://vector.im/beta.
The develop branch is continuously deployed by Jenkins at https://vector.im/develop for
those who like living dangerously.
To host your own copy of Vector, the quickest bet is to use a pre-built released version
of Vector:
1. Download the latest version from https://vector.im/packages/
1. Untar the tarball on your web server
1. Move (or symlink) the vector-x.x.x directory to an appropriate name
1. If desired, copy `config.sample.json` to `config.json` and edit it
as desired. See below for details.
1. Enter the URL into your browser and log into vector!
Important Security Note
=======================
We do not recommend running Vector from the same domain name as your Matrix
homeserver. The reason is the risk of XSS (cross-site-scripting) vulnerabilities
that could occur if someone caused Vector to load and render malicious user generated
content from a Matrix API which then had trusted access to Vector (or other apps) due
to sharing the same domain.
We have put some coarse mitigations into place to try to protect against this situation,
but it's still not good practice to do it in the first place.
See https://github.com/vector-im/vector-web/issues/1977 for more details.
Building From Source
====================
Vector is a modular webapp built with modern ES6 and requires a npm build system to build.
1. Install or update `node.js` so that your `npm` is at least at version `2.0.0`
1. Clone the repo: `git clone https://github.com/vector-im/vector-web.git`
1. Switch to the vector directory: `cd vector-web`
1. Install the prerequisites: `npm install`
1. If you are using the `develop` branch of vector, you will probably need to
rebuild one of the dependencies, due to https://github.com/npm/npm/issues/3055:
`(cd node_modules/matrix-react-sdk && npm install)`
1. Configure the app by copying `config.sample.json` to `config.json` and modifying
it (see below for details)
1. `npm run package` to build a tarball to deploy. Untaring this file will give
a version-specific directory containing all the files that need to go on your
web server.
Note that `npm run package` is not supported on Windows, so Windows users can run `npm
run build`, which will build all the necessary files into the `vector`
directory. The version of Vector will not appear in Settings without
using the package script. You can then mount the vector directory on your
webserver to actually serve up the app, which is entirely static content.
config.json
===========
You can configure the app by copying `vector/config.sample.json` to
`vector/config.json` and customising it:
1. `default_hs_url` is the default home server url.
1. `default_is_url` is the default identity server url (this is the server used
for verifying third party identifiers like email addresses). If this is blank,
registering with an email address, adding an email address to your account,
or inviting users via email address will not work. Matrix identity servers are
very simple web services which map third party identifiers (currently only email
addresses) to matrix IDs: see http://matrix.org/docs/spec/identity_service/unstable.html
for more details. Currently the only public matrix identity servers are https://matrix.org
and https://vector.im. In future identity servers will be decentralised.
Running as a Desktop app
========================
In future we'll do an official distribution of Vector as an desktop app. Meanwhile,
there are a few options:
@asdf:matrix.org points out that you can use nativefier and it just works(tm):
```
sudo npm install nativefier -g
nativefier https://vector.im/beta/
```
krisa has a dedicated electron project at https://github.com/krisak/vector-electron-desktop
(although you should swap out the 'vector' folder for the latest vector tarball you want to run.
Get a tarball from https://vector.im/packages or build your own - see Building From Source
above).
There's also a (much) older electron distribution at https://github.com/stevenhammerton/vector-desktop
Development
===========
Before attempting to develop on Vector you **must** read the developer guide
for `matrix-react-sdk` at https://github.com/matrix-org/matrix-react-sdk, which
also defines the design, architecture and style for Vector too.
The idea of Vector is to be a relatively lightweight "skin" of customisations on
top of the underlying `matrix-react-sdk`. `matrix-react-sdk` provides both the
higher and lower level React components useful for building Matrix communication
apps using React.
After creating a new component you must run `npm run reskindex` to regenerate
the `component-index.js` for the app (used in future for skinning)
**However, as of July 2016 this layering abstraction is broken due to rapid
development on Vector forcing `matrix-react-sdk` to move fast at the expense of
maintaining a clear abstraction between the two.** Hacking on Vector inevitably
means hacking equally on `matrix-react-sdk`, and there are bits of
`matrix-react-sdk` behaviour incorrectly residing in the `vector-web` project
(e.g. matrix-react-sdk specific CSS), and a bunch of Vector specific behaviour
in the `matrix-react-sdk` (grep for Vector). This separation problem will be
solved asap once development on Vector (and thus matrix-react-sdk) has
stabilised. Until then, the two projects should basically be considered as a
single unit. In particular, `matrix-react-sdk` issues are currently filed
against `vector-web` in github.
Please note that Vector is intended to run correctly without access to the public
internet. So please don't depend on resources (JS libs, CSS, images, fonts)
hosted by external CDNs or servers but instead please package all dependencies
into Vector itself.
Setting up a dev environment
============================
Much of the functionality in Vector is actually in the `matrix-react-sdk` and
`matrix-js-sdk` modules. It is possible to set these up in a way that makes it
easy to track the `develop` branches in git and to make local changes without
having to manually rebuild each time.
First clone and build `matrix-js-sdk`:
1. `git clone git@github.com:matrix-org/matrix-js-sdk.git`
1. `pushd matrix-js-sdk`
1. `git checkout develop`
1. `npm install`
1. `npm install source-map-loader` # because webpack is made of fail (https://github.com/webpack/webpack/issues/1472)
1. `popd`
Then similarly with `matrix-react-sdk`:
1. `git clone git@github.com:matrix-org/matrix-react-sdk.git`
1. `pushd matrix-react-sdk`
1. `git checkout develop`
1. `npm install`
1. `rm -r node_modules/matrix-js-sdk; ln -s ../../matrix-js-sdk node_modules/`
1. `popd`
Finally, build and start vector itself:
1. `git clone git@github.com:vector-im/vector-web.git`
1. `cd vector-web`
1. `git checkout develop`
1. `npm install`
1. `rm -r node_modules/matrix-js-sdk; ln -s ../../matrix-js-sdk node_modules/`
1. `rm -r node_modules/matrix-react-sdk; ln -s ../../matrix-react-sdk node_modules/`
1. `npm start`
1. Wait a few seconds for the initial build to finish; you should see something like:
```
Hash: b0af76309dd56d7275c8
Version: webpack 1.12.14
Time: 14533ms
Asset Size Chunks Chunk Names
bundle.js 4.2 MB 0 [emitted] main
bundle.css 91.5 kB 0 [emitted] main
bundle.js.map 5.29 MB 0 [emitted] main
bundle.css.map 116 kB 0 [emitted] main
+ 1013 hidden modules
```
Remember, the command will not terminate since it runs the web server
and rebuilds source files when they change. This development server also
disables caching, so do NOT use it in production.
1. Open http://127.0.0.1:8080/ in your browser to see your newly built Vector.
When you make changes to `matrix-react-sdk`, you will need to run `npm run
build` in the relevant directory. You can do this automatically by instead
running `npm start` in the directory, to start a development builder which
will watch for changes to the files and rebuild automatically.
If you add or remove any components from the Vector skin, you will need to rebuild
the skin's index by running, `npm run reskindex`.
If any of these steps error with, `file table overflow`, you are probably on a mac
which has a very low limit on max open files. Run `ulimit -Sn 1024` and try again.
You'll need to do this in each new terminal you open before building vector.
Filing issues
=============
All issues for Vector-web and Matrix-react-sdk should be filed at
https://github.com/matrix-org/matrix-react-sdk/issues
Triaging issues
===============
Issues will be triaged by the core team using the following primary set of tags:
priority:
P1: top priority; typically blocks releases.
P2: one below that
P3: non-urgent
P4/P5: bluesky some day, who knows.
bug or feature:
bug severity:
* cosmetic - feature works functionally but UI/UX is broken.
* critical - whole app doesn't work
* major - entire feature doesn't work
* minor - partially broken feature (but still usable)
* release blocker
* ui/ux (think of this as cosmetic)
* network (specific to network conditions)
* platform (platform specific)
Enabling encryption
===================
End-to-end encryption in Vector and Matrix is not yet considered ready for
day-to-day use; it is experimental and should be considered only as a
proof-of-concept. See https://matrix.org/jira/browse/SPEC-162 for an overview
of the current progress.
To enable the (very experimental) support, check the 'End-to-End Encryption'
box in the 'Labs' section of the user settings (note that the labs are disabled
on http://vector.im/beta: you will need to use http://vector.im/develop or your
own deployment of vector). The Room Settings dialog will then show an
'Encryption' setting; rooms for which you are an administrator will offer you
the option of enabling encryption. Any messages sent in that room will then be
encrypted.
Note that historical encrypted messages cannot currently be decoded - history
is therefore lost when the page is reloaded.
