This is an app for Slack that renders Mermaid diagrams in Slack.
This app adds a /mermaid command to your Slack workspace. You can use it to post Mermaid diagrams in Slack messages.
The app listens for a /mermaid command and opens a Slack modal where you can enter your Mermaid diagram code. After you submit the modal, the app renders the diagram using Mermaid CLI into a PNG file. This PNG is uploaded to Slack and posted as a message. PNG is deleted from the server after it's posted.
- Edit already posted diagram (through Modal?)
- Automatically detect Mermaid diagrams in messages and render them?
- Live preview of the mermaid document in the modal? Seems like this can't be done with Slack's UI limitations.
- Support DMs, more context in the comment.
