Summary of Changes

Hello @n1ru4l, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request rectifies a critical bug within the CLI's schema minification utility, which was inadvertently generating malformed Schema Definition Language (SDL). The core of the solution involves simplifying the minification algorithm to ensure that only whitespace is consistently processed, thereby guaranteeing the integrity and validity of the output schema.

Highlights

  • Schema Minification Fix: Resolved an issue where the CLI's schema minification process produced invalid Schema Definition Language (SDL).
  • Simplified Minification Logic: Refactored the minifySchema function to use a simpler regex for whitespace replacement, removing complex logic that previously handled triple-quoted blocks and comments.
Changelog
  • .changeset/light-shirts-pay.md
    • Added a new changeset entry for a patch release, documenting the fix for invalid schema SDL minification.
  • packages/libraries/cli/src/helpers/schema.ts
    • Modified the minifySchema function to use a simplified regex for whitespace replacement.
    • Removed the previous complex regex that attempted to preserve triple-quoted strings and remove comments, which was identified as the cause of invalid SDL generation.

Code Review

The PR simplifies the minifySchema function but introduces a regression by mangling whitespace within GraphQL descriptions and string literals. This destroys formatting in multi-line descriptions (such as Markdown lists) and can alter the values of string arguments, which contradicts the goal of preserving schema semantics during minification. It also reverts a fix introduced in version 0.58.1.

This change mangles GraphQL descriptions and string literals by replacing internal whitespace with a single space. This breaks Markdown formatting in multi-line descriptions (e.g., lists or paragraphs in """ blocks) and alters the values of string arguments or default values.

Minification must preserve the content of string literals. The previous implementation's approach of identifying and skipping string blocks should be maintained and improved (e.g., to handle escaped quotes) rather than replaced with a destructive global whitespace replacement.

  return schema
    .replace(/(?:("""[\s\S]*?"""|"(?:\\.|[^"])*")|#[^\r\n]*|\s+)/g, (match, group1) => {
      if (group1) return group1;
      return ' ';
    })
    .trim();
