Wekan v4.29 changes markdown rendering from marked to markdown-it.
With markdown-it, also markdown-it-emoji plugin has been added, supporting full list of GitHub emojis.
Example emoji code, that you can add for example to card name, card description etc:
:rainbow: :thumbsup: :100:
That shows emojis 🌈 👍 💯
For markdown-it, there are also other syntax extensions where some are listed at that markdown-it page, and others at npmjs.com.
For example, how to get some mermaid plugin working so that some syntax works for https://mermaid-js.github.io/mermaid/ ?
Using newest Ubuntu amd64:
sudo apt -y install git
git config --global user.name "Yourfirstname Yourlastname"
git config --global user.email email-address-you-use-at-github@example.com
git config --global push.default simple
nano .ssh/config
There add your User (GitHub username) and IdentityFile (Your ssh private key. Not public key that has .pub). For indentation, use one tab.
Host *
IdentitiesOnly=yes
Host github.com
Hostname github.com
User xet7
IdentityFile ~/.ssh/id_xet7ed
Save and Exit with Ctrl-o Enter Ctrl-x Enter
If you do not have ssh key, create it:
ssh-keygen
And press Enter about 3 times, until you have private key at ~/.ssh/id_rsa and public key at ~/.ssh/id_rsa.pub
Add public key .pub to your github account web interface.
Add path to Meteor:
nano .bashrc
There at bottom add:
export PATH=~/.meteor:$PATH
Save and Exit with Ctrl-o Enter Ctrl-x Enter
mkdir repos
cd repos
git clone git@github.com:YourGithubUsername/wekan.git
cd wekan
IMPORTANT: Do NOT npm audit fix --force, it downgrades @meteorjs/rspack and breaks builds.
npm audit shows false info, it does not recognize that elliptic is already updated
to 6.6.1 with override at package.json like you can see with npm list elliptic.
https://github.com/wekan/wekan/blob/main/CHANGELOG.md#v850-2026-04-03-wekan--release
./rebuild-wekan.sh
1
./rebuild-wekan.sh
2
./rebuild-wekan.sh
3
That does: 1 install dependencies, 2 builds wekan, 3 starts wekan in development mode with command meteor, so it can detect if some file changes and try to rebuild automatically and reload webbroser. But, still sometimes, it may need stopping with Ctrl-c and full build with option 2.
And then register and login at http://localhost:4000
meteor npm install markdown-it-something --save
Edit file wekan/packages/markdown/src-integration.js and add using that new package, using code example from that new plugin page, or similar like emoji plugin was added.
Test does that new plugin syntax work, for example in card title, card description etc on other input fields.
If normal markdown, emoji, and your new added plugin syntax all work, commit your changes:
git add --all
git commit -m "Added plugin markdown-it-something."
git push
And then at your GitHub for https://github.com/YOUR-GITHUB-USERNAME/wekan click Create pull request.
Updating to next Meteor release:
meteor update
meteor npm update
Updating to specific Meteor release:
meteor update --release METEOR@3.4
If you are changing Meteor and Node.js versions, you may need to reset Meteor:
meteor reset
Or alternatively, delete wekan repo (if you did not need any changes you made), and clone wekan repo again, and then build etc.
