A serverless function that generates SVG mindmaps from indented text data.

This API converts hierarchical text data into visual mindmap diagrams in SVG format. The root node is placed in the center, with child nodes branching out to the left and right sides.

Since it does not rely on external SVG rendering libraries, it can be easily used as a serverless function.

Generates a mindmap SVG from the provided text data.

Can be sent as a JSON body or as form data with application/x-www-form-urlencoded.

A sample of base64image is in test/base64image.txt.

Note about code:

• Write each item on one line.
• Use the number of leading spaces to indicate the depth of the tree structure.
• The highest level (root node) should have one leading space.
• The root node must be the first line of the text.

Samples of code are in test/code*.txt.

Use test/code1.txt as code and test/base64image.txt as base64image.

This is a Next.js app.

• app/api/mindmap/route.tsx is the API endpoint.
• lib/TreeNode.ts is the class for the tree node.

You can test the API by GET function in app/api/mindmap/route.tsx. Please uncomment the GET function code in the file.

Run npm run dev to start the server. Open http://localhost:3000/api/mindmap with query parameters in your browser.

You can easily deploy this API as a serverless function to Vercel.

1. Clone this repository.
2. Run npm install.
3. Install Vercel CLI.
4. Run vercel login.
5. Run vercel.
