Use Slack View to live stream a Slack channel on a web site.

Slack View demo:

The latest version of Slack View now features Real-Time-Streaming of Slack channels to multiple Slack View web pages. You can personalize Slack View with themes and deploy Slack View as a Docker container.

Slack View leverages Python and Flask-SocketIO to achieve real time streaming of Slack events. The rendered Slack View page becomes a read only display of Slack channel.

A custom implementation of Slack View at, live streams a #bad-actors Slack channel of hackers probing and attempting to infiltrate a system. This demonstrates how Slack messages in a channel can be published outside a Slack client. In this example, stakeholders who normally don’t use Slack, suddenly realize that their systems are constantly under siege by bad actors like “Steven Seagal” and are grateful for those IT Security policies that protect the organization.

Another implementation of Slack View could be to embed Slack support channels into a dashboard to monitor multiple discussions, war rooms or issues.

  3. Run the Docker image with the volume switch to mount your config directory as /config in the image. For example:
    docker run -v /path/to/config_dir:/config -p 7000:7000 -e TZ=Australia/Brisbane meltaxa/slackview

PHP version

Slack View was originally written in PHP which only provided a snapshot of the channel and a page refresh is required to display the latest messages. For posterity, the php version of Slack View is available under the GitHub php branch.
