Veija slack app rule

veija_rule.js

// Veija slack app rule
// This opens slack channel or message links in the slack app.
//
// 1. Log in to your slack workspace in a browser and copy 
//    your team id (TXXXXXXXXX) from the url: e.g. "T012345679A" 
//    from "https://app.slack.com/client/T012345679A/C0123456789"
// 2. Create a new veija rule that matches url domain and
//    subdomain on <yourslackteam>.slack.com
// 3. Enable 'Transform URL' for the rule, Edit script and paste
//    this code. Make sure to replace the value of TEAM_ID with
//    your actual id.

const TEAM_ID = "T0000000000";

const m = $.url.pathname.match(/\/archives\/(C\w+)(?:\/p(\d+))?/);
if (m) {
  const channelId = m[1];
  const messageTs = m[2];

  let url = `slack://channel?team=${TEAM_ID}&id=${channelId}`;

  // add message timestamp if present
  if (messageTs) {
    url += `&message=${messageTs}`;
  }

  // parse thread_ts from query params if present
  const queryParams = new URLSearchParams($.url.search);
  const threadTs = queryParams.get('thread_ts');
  if (threadTs) {
    url += `&thread_ts=${threadTs}`;
  }

  $.url = url;
}

Line 15:

const m = $.url.pathname.match(//archives/(C\w+)(?:/p(\d+))?/);

Will not work on DMs (which start with a D not a C)

But if you change it to:

const m = $.url.pathname.match(//archives/([CD]\w+)(?:/p(\d+))?/);

Then it will work on DMs too.
