This blog post announces the Mermaid Chart VS Code plugin, a tool that simplifies creating and editing Mermaid.js diagrams directly within Visual Studio Code. The plugin provides live preview rendering, allowing users to see their diagram update in real-time as they edit the Mermaid.js code. It also offers features like syntax highlighting, linting for error detection, and autocompletion to streamline the diagram creation process. The plugin aims to make working with Mermaid.js diagrams more efficient and integrated within the VS Code environment.
This Hacker News post announces the release and features of a Visual Studio Code plugin specifically designed for working with Mermaid.js diagrams. Mermaid.js is a JavaScript library that allows users to create various types of diagrams, including flowcharts, sequence diagrams, Gantt charts, class diagrams, state diagrams, entity relationship diagrams, user journey diagrams, pie charts, requirement diagrams, and more, from text-based markup. This plugin aims to simplify the process of creating and editing these diagrams directly within the VS Code editor.
The plugin boasts a live preview feature, meaning that any changes made to the Mermaid.js code are immediately reflected in a visual representation of the diagram, allowing for real-time feedback and iteration. It supports all the diagram types offered by Mermaid.js, ensuring full compatibility with the library. Furthermore, it offers syntax highlighting and code completion for Mermaid.js syntax within VS Code, enhancing code readability and reducing errors. This autocompletion assists users in quickly writing correct Mermaid.js markup by suggesting relevant keywords, syntax elements, and even custom directives defined within the diagram.
The plugin facilitates diagram exporting in various formats, including SVG, PNG, and PDF, offering flexibility for sharing and incorporating diagrams into different documents and presentations. Users can easily switch between the code editor and the live preview to check the visual output of their Mermaid.js code. The post highlights the ease of installation through the VS Code marketplace, emphasizing the plugin's accessibility to users already working within the VS Code environment. The aim is to provide a seamless and integrated diagramming experience without the need to leave the editor. The post links to both the VS Code Marketplace entry for the extension and comprehensive documentation for the plugin, offering users resources for installation, usage instructions, and further details on the plugin's capabilities.

Hacker News users generally expressed positive sentiment towards the Mermaid Chart VS Code plugin. Several commenters appreciated the convenience and improved workflow it offered for creating and editing diagrams directly within VS Code. Some highlighted specific features they found useful, such as live preview and syntax highlighting. A few users mentioned alternative tools they preferred, like PlantUML and Excalidraw, but acknowledged the plugin's value for those already working within the Mermaid.js ecosystem. One commenter noted the benefit of having diagrams as code, enabling version control and collaborative editing. There was also a brief discussion regarding the licensing of the plugin and the underlying Mermaid.js library.
The Hacker News post discussing the Mermaid Chart VS Code plugin has a modest number of comments, focusing primarily on existing alternatives and some limitations of the plugin.
Several commenters pointed out the existence of Markdown Preview Enhanced, another VS Code extension that supports Mermaid.js rendering among other features. This sparked a small discussion about the relative merits of each, with some users suggesting Markdown Preview Enhanced as a more comprehensive solution due to its wider feature set beyond just Mermaid diagrams. However, proponents of the dedicated Mermaid Chart plugin emphasized its focused approach and potentially better performance or specific features tailored to Mermaid.js workflows. A nuance mentioned is that the Mermaid Chart plugin allows "live editing" within the editor itself, potentially streamlining the diagram creation process.
Another point raised was the desire for a web-based Mermaid.js editor with similar live editing capabilities, independent of a specific IDE like VS Code. This suggests a preference among some users for a more platform-agnostic solution.
Finally, at least one commenter noted that the Mermaid Chart VS Code plugin doesn't seem to support all Mermaid.js features, specifically mentioning sequence diagrams with loops. This highlights that while the plugin offers a convenient way to work with Mermaid.js within VS Code, it might not be fully feature-complete for all use cases.
