Package Manager Improvements - Bun-Inspired Features

This document outlines future improvements to Home's package manager, taking inspiration from Bun's excellent developer experience.

🚀 Performance Improvements

1. Parallel Downloads (Like Bun)

Status: 🟡 Planned Priority: High Impact: Massive speed improvement

Bun downloads packages in parallel, making installations incredibly fast. Home should do the same.

Implementation:

// Use Zig's thread pool for parallel downloads
const ThreadPool = std.Thread.Pool;

fn downloadAllParallel(self: *PackageManager) !void {
    var pool: ThreadPool = undefined;
    try pool.init(.{ .allocator = self.allocator });
    defer pool.deinit();

    // Spawn parallel download tasks
    for (lock.packages.items) |pkg| {
        try pool.spawn(downloadPackageAsync, .{ self, pkg });
    }

    // Wait for all downloads
    pool.waitAndWork();
}

Benefits:

• 5-10x faster installations
• Better network utilization
• Improved developer experience

2. Global Content-Addressable Cache

Status: 🟡 Planned Priority: High Impact: Disk space savings + faster installs

Like Bun, store packages globally and symlink them into projects.

Cache Structure:

~/.home/
  cache/
    packages/
      <hash1>/  # Content-addressed by checksum
      <hash2>/
      <hash3>/
    registry/
      metadata.json

Benefits:

• Install a package once, use everywhere
• Massive disk space savings
• Instant installs for cached packages
• Atomic operations

3. HTTP/2 and Compression

Status: 🔴 Not Started Priority: Medium Impact: Faster downloads

// Use HTTP/2 with compression
const http_client = std.http.Client.init(allocator);
defer http_client.deinit();

// Enable compression
http_client.compression = .gzip;

Benefits:

• Smaller downloads
• Faster transfers
• Better bandwidth usage

🎨 User Experience Improvements

4. Beautiful Progress UI

Status: 🔴 Not Started Priority: High Impact: Developer delight

Bun shows beautiful progress bars with speed indicators. Home should too!

Example Output:

📦 Installing 24 packages...

⠋ http-router@1.0.0          [████████████████████] 100% | 2.3 MB/s
⠋ zyte@main                  [█████████░░░░░░░░░░░]  45% | 1.8 MB/s
✓ json-parser@2.1.0          [████████████████████] 100% | 3.1 MB/s

⠋ 3 packages remaining... (avg 2.4 MB/s)

Implementation:

const ProgressBar = struct {
    name: []const u8,
    current: usize,
    total: usize,
    speed_mbps: f64,

    pub fn render(self: _ProgressBar) void {
        const percent = @as(f64, @floatFromInt(self.current)) / @as(f64, @floatFromInt(self.total)) _ 100.0;
        const bar_width = 20;
        const filled = @as(usize, @intFromFloat(percent / 100.0 * @as(f64, @floatFromInt(bar_width))));

        std.debug.print("\r⠋ {s:<30} [", .{self.name});

        var i: usize = 0;
        while (i < bar_width) : (i += 1) {
            if (i < filled) {
                std.debug.print("█", .{});
            } else {
                std.debug.print("░", .{});
            }
        }

        std.debug.print("] {d:.0}% | {d:.1} MB/s", .{ percent, self.speed_mbps });
    }
};

5. Package Scripts (Like package.json scripts)

Status: 🟡 Planned Priority: Medium Impact: Better workflow automation

Add script support to ion.toml like Bun/npm:

[package]
name = "my-app"
version = "1.0.0"

[scripts]
dev = "ion run src/main.home --watch"
build = "ion build src/main.home -o dist/app"
test = "ion test tests/"
bench = "ion bench bench/"
format = "ion fmt src/"

Usage:

# Run scripts like Bun
ion run dev
ion run build
ion run test

6. Workspaces for Monorepos

Status: 🟡 Planned Priority: High Impact: Essential for large projects

Support Bun-style workspaces for monorepos:

[package]
name = "my-monorepo"
version = "1.0.0"

[workspaces]
packages = [
  "packages/_",
  "apps/_"
]

Structure:

my-monorepo/
  ion.toml
  packages/
    http-router/
      ion.toml
    json-parser/
      ion.toml
  apps/
    web/
      ion.toml
    api/
      ion.toml

Features:

• Shared dependencies (hoist to root)
• Workspace-aware linking
• Cross-workspace references
• Single ion pkg install for entire monorepo

📦 Package Registry Improvements

7. Fast Package Metadata

Status: 🔴 Not Started Priority: Medium Impact: Faster dependency resolution

Like Bun, cache package metadata locally:

~/.home/
  registry/
    metadata/
      http-router.json
      zyte.json
    index.json

Benefits:

• Instant dependency resolution
• Offline capability
• Reduced registry load

8. Package Publishing

Status: 🔴 Not Started Priority: High Impact: Ecosystem growth

Make it easy to publish packages:

# Initialize package for publishing
ion pkg init --publish

# Publish to registry
ion pkg publish

# With tag
ion pkg publish --tag beta

ion.toml for publishing:

[package]
name = "my-awesome-lib"
version = "1.0.0"
description = "An awesome Home library"
license = "MIT"
repository = "https://github.com/user/my-awesome-lib"
keywords = ["http", "server", "fast"]

[package.publish]
registry = "https://packages.home-lang.org"
include = ["src/", "README.md", "LICENSE"]
exclude = ["tests/", "bench/"]

🔒 Security Improvements

9. Package Integrity Verification

Status: 🟡 Partial (checksums only) Priority: High Impact: Security and trust

Like Bun, verify package integrity:

pub const PackageVerifier = struct {
    pub fn verifyChecksum(pkg: []const u8, expected: []const u8) !bool {
        var hasher = std.crypto.hash.sha256.init(.{});
        hasher.update(pkg);
        var hash: [32]u8 = undefined;
        hasher.final(&hash);

        const computed = try std.fmt.allocPrint(allocator, "{s}", .{
            std.fmt.fmtSliceHexLower(&hash)
        });
        defer allocator.free(computed);

        return std.mem.eql(u8, computed, expected);
    }

    pub fn verifySignature(pkg: []const u8, signature: []const u8) !bool {
        // Verify package signature with public key
        // TODO: Implement signature verification
        _ = pkg;
        _ = signature;
        return true;
    }
};

10. Audit Command

Status: 🔴 Not Started Priority: Medium Impact: Security awareness

# Check for known vulnerabilities
ion pkg audit

# Fix automatically where possible
ion pkg audit --fix

Output:

🔍 Auditing 24 packages...

⚠️  Found 2 vulnerabilities:

  Moderate: Denial of Service in http-router@1.0.0
  Path: http-router > internal-parser
  Fix: Upgrade to http-router@1.0.1

  High: Remote Code Execution in old-lib@0.5.0
  Path: old-lib
  Fix: Remove dependency or upgrade

Run `ion pkg audit --fix` to automatically fix 1 vulnerability.

⚡ Smart Features

11. Dependency Deduplication

Status: 🔴 Not Started Priority: Medium Impact: Smaller installations

Smart deduplication like Bun:

  app/
    node_modules/
      package-a/
        node_modules/
          lodash@4.17.0
      package-b/
        node_modules/
          lodash@4.17.0

After (with deduplication):
  app/
    .home/
      lodash@4.17.0  # Shared instance
    node_modules/
      package-a/  # Links to shared lodash
      package-b/  # Links to shared lodash

12. Auto-Install on Import

Status: 🔴 Not Started Priority: Low Impact: Convenience

Like Bun, auto-install missing packages:

import "http-router"  // Not installed yet

// Home automatically runs: home pkg add http-router
// Then continues execution

Configuration:

[package.auto-install]
enabled = true
prompt = true  # Ask before installing

13. Lockfile Maintenance
