Extensible Slack App for link unfurling
=======================================

[](#extensible-slack-app-for-link-unfurling)

*Slack app for [unfurling](https://api.slack.com/docs/message-link-unfurling) issue links*

Slack App
---------

[](#slack-app)

[Create](https://api.slack.com/apps/new) or [Manage](https://api.slack.com/apps) your app.

You need `Verification Token` (`SLACK_VERIFICATION_TOKEN`) for next step.

Under `Features`:

- enable [Events API](http://api.slack.com/events-api) for [`link_shared`](https://api.slack.com/events/link_shared) event with `links:read` scope.
    1. Click `Event Subscriptions` on the left.
    2. Click `Enable Events`.
    3. Click `Add Workspace Event` and add `link_shared`.
    4. Click `Add Domain` and type your domain.
    5. Click `Save Changes`.
- add `links:write` permission scope
    1. Click `OAuth & Permissions` on the left.
    2. Go to `Scopes` section and select `Add link previews to messages` in the list of permissions.
    3. Click `Save Changes`.
- enable `Incoming Webhooks`

Obtain `OAuth Access Token` (`SLACK_API_TOKEN`) under `OAuth & Permissions`

Configuration
-------------

[](#configuration)

```
cp env.example .env

```

Adding providers
----------------

[](#adding-providers)

The app itself handles no links, you need to add some providers:

- [Eventum Provider](https://github.com/eventum/slack-unfurl-eventum)
- [GitLab Provider](https://github.com/glensc/slack-unfurl-gitlab)
- [Jira Provider](https://github.com/glensc/slack-unfurl-jira)
- [Zendesk Provider](https://github.com/rcknr/slack-unfurl-zendesk)
- [Pagerduty Provider](https://github.com/glensc/slack-unfurl-pagerduty)

Troubleshoot
------------

[](#troubleshoot)

If the unfurl is not happening check that the domain is not [blacklisted](https://my.slack.com/admin/attachments).

If you modify app domains, you need to `Install App` (`/install-on-team` as url) again to re-authorize:

- [https://api.slack.com/reference/messaging/link-unfurling#configuring\_domains](https://api.slack.com/reference/messaging/link-unfurling#configuring_domains)

Development
-----------

[](#development)

Install composer deps and start builtin HTTP server:

```
composer install
composer run server

```

To build docker image locally and run it:

```
docker build -t slack-unfurl .
docker run --rm -p 4390:4390 -v $(pwd)/var/log:/app/var/log -v $(pwd)/.env:/app/.env slack-unfurl

```
