🐞 Bug: tsdx create generates outdated and Bun-incompatible project setup

Describe the Bug

Running bunx tsdx create <pkg-name> generates a project scaffold that relies on outdated and unmaintained TSDX internals. The generated package.json includes tsdx@^1.0.0, legacy scripts, and configurations that are not compatible with modern tooling, especially Bun.

As a result, bun install fails because Bun cannot resolve tsdx@^1.0.0, even though the package previously existed on npm. The generated output is out of sync with current best practices and modern build tools.

---

Steps to Reproduce

1. Run:

   bunx tsdx create <pkg-name>

2. Navigate into the generated project

3. Run:

   bun install

4. Observe the installation failure

---

Expected Behavior

• The scaffolded project should:

  • Use maintained, modern tooling (e.g. tsup, vite, or Bun-compatible alternatives)
  • Avoid dependencies on unpublished or archived packages
  • Generate a package.json that installs cleanly with modern runtimes (Node ≥20, Bun)

• Alternatively, tsdx create should warn that:

  • TSDX is archived / deprecated
  • Bun is not supported

---

Actual Behavior

• The generated package.json includes:

  "devDependencies": {
    "tsdx": "^1.0.0"
  }

• Running bun install fails with:

error: No version matching "^1.0.0" found for specifier "tsdx"
error: tsdx@^1.0.0 failed to resolve

• The generated scripts (tsdx dev, tsdx build, etc.) are unusable in Bun and rely on deprecated tooling.

Screenshots / Logs

bun install v1.2.19 (aad3abea)
error: No version matching "^1.0.0" found for specifier "tsdx"
error: tsdx@^1.0.0 failed to resolve

---

Environment

TSDX version: not installed (resolved via bunx)
Node version: v20.x.x
Bun version: 1.2.19
OS: macOS
Template used: default (React library)

Run used to collect versions:

echo "TSDX: $(bunx tsdx --version 2>/dev/null || echo 'not installed')"
echo "Node: $(node --version)"
echo "Bun: $(bun --version)"
echo "OS: $(uname -a)"

---

Additional Context

• TSDX appears to be archived / unmaintained, but tsdx create still generates new projects without warning.

• The generated configuration does not align with:

  • Modern ESM standards
  • Bun’s strict dependency resolver
  • Current React library best practices

• This leads to a broken first-time experience for users using Bun or modern Node tooling.

Suggestion:

• Deprecate tsdx create, or
• Explicitly document that Bun is unsupported and the tool is legacy.
