From 63595f35bc5718082020fe469812d09a7ea7946a Mon Sep 17 00:00:00 2001 From: Claude Bot Date: Mon, 15 Sep 2025 08:05:46 +0000 Subject: [PATCH] fix: correct dependency chain structure in JSON output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING FIX: JSON now shows correct dependency chain from root to target Previously showed target package with its dependents as children (backwards). Now correctly shows the path from root package to the target package. Example for 'bun why body-parser' in a project with express: { "name": "my-project", "dependencies": { "express": { "from": "^4.18.0", // Actual spec from package.json "dependencies": { "body-parser": { "from": "1.20.3", // Actual spec from express's package.json ... } } } } } Changes: - Shows dependency chain from root to target (not backwards) - "from" field now shows actual dependency specifier from lockfile - All data comes from lockfile (no package.json reads needed) - Works for both direct and nested dependencies 🤖 Generated with Claude Code Co-Authored-By: Claude --- src/cli/why_command.zig | 231 ++++++++++++++++++---------- test/cli/install/bun-pm-why.test.ts | 24 +-- 2 files changed, 151 insertions(+), 104 deletions(-) diff --git a/src/cli/why_command.zig b/src/cli/why_command.zig index 04b01e013d..8bbbd84827 100644 --- a/src/cli/why_command.zig +++ b/src/cli/why_command.zig @@ -347,13 +347,16 @@ pub const WhyCommand = struct { } if (json_output) { - // Build JSON output using proper JSON formatting + // Build JSON output showing dependency chain from root to target var json_buf = bun.MutableString.init(ctx.allocator, 0) catch unreachable;
