What this developer tool does
Applies block-aware whitespace normalization and indentation to Vue template, script, and style content.
Split lines → infer tag depth → normalize whitespace → count changed lines
Heuristic formatting preserves code but cannot match a full AST formatter in every edge case.
Example
Use the preloaded sample, run the tool, then inspect the output and status before copying it into a project.
Tips for better output
- Use complete framework code when possible.
- Select the matching framework version.
- Review heuristic findings before changing production code.
- Run the project compiler and tests after using generated or transformed output.
