Installation

There are 4 different ways to install XMPP Web:

Ansible

Long time ago, we provided an Ansible role. It had not been updated since 2020 and nobody used it, it is not maintained anymore. You can still use it but it will not set all the relevant configuration in local.js.

Archive

You can download latest .tar.gz archive, unpack files in web directory and configure:

wget https://github.com/nioc/xmpp-web/releases/latest/download/xmpp-web-0.9.7.tar.gz \
  -O /var/tmp/xmpp-web.tar.gz \
  && cd /var/www \
  && tar -xvzf /var/tmp/xmpp-web.tar.gz \
  && chown www-data /var/www/xmpp-web/ -R

Docker image

On each release, we also build a Docker image which is the latest stable Nginx (Alpine variant in order to keep lightweight) serving the generated assets. Configuration in local.js is set up according to environment variables (names and meanings are explained in configuration section).

This can be used:

  • as standalone service:

    docker run -it -p 80:80 --rm \
    -e XMPP_WS=https://domain-xmpp.ltd:5281/xmpp-websocket \
    -e APP_DEFAULT_DOMAIN=domain-xmpp.ltd \
    --name xmpp-web-1 nioc/xmpp-web
  • in a docker-compose.yml file:

    version: "3.4"
    services:
      xmpp-web:
        image: nioc/xmpp-web:latest
        ports:
          - "80:80"
        environment: 
          - XMPP_WS=https://domain-xmpp.ltd:5281/xmpp-websocket
          - APP_DEFAULT_DOMAIN=domain-xmpp.ltd

Build from source

If you want the latest code without waiting for the next release, you can clone this repo, build assets and copy dist files in web directory:

git clone https://github.com/nioc/xmpp-web.git xmpp-web
cd xmpp-web
npm ci
npm run build
nano dist/local.js
mv dist /var/www/xmpp-web
chown www-data /var/www/xmpp-web/ -R

Upgrade

Archive

Use the same method as installation or use the update.sh script. After that, do not forget to edit local.js.

Docker image

Use docker pull nioc/xmpp-web:latest and check if there is some new environment variables to set.
